Demographic, clinical and social factors associated with human immunodeficiency virus infection and other sexually transmitted diseases in a cohort of women from the United Kingdom and Ireland. MRC Collaborative Study of women with HIV. (1/1248)

BACKGROUND: Clinical experience suggests many women with HIV infection have experienced no other sexually transmitted diseases (STD). Our objective was to test the hypothesis that a substantial proportion of women with HIV infection in the United Kingdom and Ireland have experienced no other diagnosed STD and to describe the demographic, clinical and social factors associated with the occurrence of other STD in a cohort of HIV infected women. METHOD: Analysis of cross-sectional baseline data from a prospective study of 505 women with diagnosed HIV infection. The setting was 15 HIV treatment centres in the United Kingdom and Ireland. The main outcome measures were occurrence of other STD diagnosed for the first time before and after HIV diagnosis. Data were obtained from interview with women and clinic notes. We particularly focused on occurrence of gonorrhoea, chlamydia and trichomoniasis after HIV diagnosis, as these are the STD most likely to reflect recent unprotected sexual intercourse. RESULTS: The women were mainly infected via heterosexual sex (n = 304), and injection drug use (n = 174). 151 were black Africans. A total of 250 (49.5%) women reported never having been diagnosed with an STD apart from HIV, 255 (50.5%) women had ever experienced an STD besides HIV, including 109 (21.6%) who had their first other STD diagnosed after HIV. Twenty-five (5%) women reported having had chlamydia, gonorrhoea or trichomoniasis diagnosed for the first time after HIV diagnosis, possibly reflecting unprotected sexual intercourse since HIV diagnosis. In all 301 (60%) women reported having had sex with a man in the 6 months prior to entry to the study. Of these, 168 (58%) reported using condoms 'always', 66(23%) 'sometimes' and 56 (19%) 'never'. CONCLUSIONS: Half the women in this study reported having never experienced any other diagnosed STD besides HIV. However, after HIV diagnosis most women remain sexually active and at least 5% had an STD diagnosed which reflect unprotected sexual intercourse.  (+info)

Incidence of acquired immunodeficiency syndrome (AIDS)-related Kaposi's sarcoma in the Aquitaine Cohort, France, 1988-1996. Groupe d'Epidemiologie Clinique du SIDA en Aquitaine. (2/1248)

OBJECTIVE: To assess secular trends of the incidence of Kaposi's sarcoma (KS) between 1988 and 1996 in the Aquitaine Cohort of human immunodeficiency virus type 1 (HIV1)-infected subjects (southwestern France). METHODS: Adults of both sexes of all HIV-transmission categories were included. We distinguished between incident and prevalent KS and in case of multiple acquired immunodeficiency syndrome (AIDS) defining illnesses between initial or subsequent KS. Only incident KS were considered for annual incidence rate calculation. RESULTS: Overall, 21.2% (356/1678) of homosexuals and 1.9% (58/3030) of the other patients were diagnosed with KS over time. Although there was a sharp decrease in 1996 for initial KS, the annual incidence rate of KS was stable over time in the overall cohort as well as in homosexuals (4.3% per year on the average for KS as an initial AIDS-defining illness and 2.1% per year for subsequent KS in homosexuals). The median CD4+ cell count at the time of diagnosis of KS was 56 per mm3 (78 for initial KS, 14 for subsequent KS), with no significant variation over time. CONCLUSION: In the Aquitaine Cohort, the annual incidence of KS has remained stable between 1988 and 1995 with a recent decline in 1996, only for initial KS, while case management of HIV-infected subjects changed drastically.  (+info)

Hygiene behaviour in rural Nicaragua in relation to diarrhoea. (3/1248)

BACKGROUND: Childhood diarrhoea is a leading cause of morbidity and mortality in Nicaragua. Amongst the risk factors for its transmission are 'poor' hygiene practices. We investigated the effect of a large number of hygiene practices on diarrhoeal disease in children aged <2 years and validated the technique of direct observation of hygiene behaviour. METHODS: A prospective follow-up study was carried out in a rural zone of Nicaragua. From the database of a previously conducted case-control study on water and sanitation 172 families were recruited, half of which had experienced a higher than expected rate of diarrhoea in their children and the other half a lower rate. Hygiene behaviour was observed over two mornings and diarrhoea incidence was recorded with a calendar, filled out by the mother, and collected every week for 5 months. RESULTS: Of 46 'good' practices studied, 39 were associated with a lower risk of diarrhoea, five were unrelated and only for two a higher risk was observed. Washing of hands, domestic cleanliness (kitchen, living room, yard) and the use of a diaper/underclothes by the child had the strongest protective effect. Schooling (>3 years of primary school) and better economic position (possession of a radio) had a positive influence on general hygiene behaviour, education having a slightly stronger effect when a radio was present. Individual hygiene behaviour appeared to be highly variable in contrast with the consistent behaviour of the community as a whole. Feasible and appropriate indicators of hygiene behaviour were found to be domestic cleanliness and the use of a diaper or underclothes by the child. CONCLUSION: A consistent relationship between almost all hygiene practices and diarrhoea was detected, more schooling producing better hygiene behaviour. The high variability of hygiene behaviour at the individual level requires repeated observations (at least two) before and after the hygiene education in the event one wants to measure the impact of the campaign on the individual.  (+info)

Virulence evolution in a virus obeys a trade-off. (4/1248)

The evolution of virulence was studied in a virus subjected to alternating episodes of vertical and horizontal transmission. Bacteriophage f1 was used as the parasite because it establishes a debilitating but non-fatal infection that can be transmitted vertically (from a host to its progeny) as well as horizontally (infection of new hosts). Horizontal transmission was required of all phage at specific intervals, but was prevented otherwise. Each episode of horizontal transmission was followed by an interval of obligate vertical transmission, followed by an interval of obligate horizontal transmission etc. The duration of vertical transmission was eight times longer per episode in one treatment than in the other, thus varying the relative intensity of selection against virulence while maintaining selection for some level of virus production. Viral lines with the higher enforced rate of infectious transmission evolved higher virulence and higher rates of virus production. These results support the trade-off model for the evolution of virulence.  (+info)

Dirt and diarrhoea: formative research in hygiene promotion programmes. (5/1248)

Investment in the promotion of better hygiene for the prevention of diarrhoeal diseases and as a component of water and sanitation programmes is increasing. Before designing programmes capable of sustainably modifying hygiene behaviour in large populations, valid answers to a number of basic questions concerning the site and the intended beneficiaries have to be obtained. Such questions include 'what practices favour the transmission of enteric pathogens?', 'what advantages will be perceived by those who adopt safe practices?' and 'what channels of communication are currently employed by the target population?' A study of hygiene and diarrhoea in Bobo-Dioulasso, Burkina Faso, used a mixture of methods to address such questions. This paper draws on that experience to propose a plan of preliminary research using a variety of techniques which could be implemented over a period of a few months by planners of hygiene promotion programmes. The techniques discussed include structured observation, focus group discussions and behavioural trials. Modest investment in such systematic formative research with clear and limited goals is likely to be repaid many times over in the increased effectiveness of hygiene promotion programmes.  (+info)

The quality of immunization data from routine primary health care reports: a case from Nepal. (6/1248)

Reported high immunization coverage achieved in Nepal over the last ten years is expected to reduce child mortality in the country. The present study, carried out in hill district in mid-west Nepal, aimed to assess the quality of immunization data in Nepal. The number of children who received different vaccines during one year was obtained from three sources: 1) the Immunization REgister of three Primary Health Care Service Outlets (PHCSOs) where each immunized child is recorded; 2) monthly PHC Reports, which are based on the Immunization Register; 3) monthly DHO Reports, which are based on the above PHC Reports (the DHO reports are the source of official statistics). The number of children in the PHC Reports was higher than the number in the Immunization REgisters for all vaccines. The number of immunizations in the DHO Reports was higher than the number in the PHC Reports for BCG, DPT, and measles; the number was lower for poliomyelitis. The overall number of immunizations was higher in the DHO Reports than in the Immunization Registers, by 31% for BCG, 44% for DPT, 155% for polio, and 71% for measles. We conclude that the official report overestimates the immunization coverage in the district. The immunization programme, therefore, might not result in the expected reduction of morbidity and mortality despite the investment in the programme and reported high coverage.  (+info)

Evolution and biological characterization of human immunodeficiency virus type 1 subtype E gp120 V3 sequences following horizontal and vertical virus transmission in a single family. (7/1248)

It has been suggested that immune-pressure-mediated positive selection operates to maintain the antigenic polymorphism on the third variable (V3) loop of the gp120 of human immunodeficiency virus type 1 (HIV-1). Here we present evidence, on the basis of sequencing 147 independently cloned env C2/V3 segments from a single family (father, mother, and their child), that the intensity of positive selection is related to the V3 lineage. Phylogenetic analysis and amino acid comparison of env C2/V3 and gag p17/24 regions indicated that a single HIV-1 subtype E source had infected the family. The analyses of unique env C2/V3 clones revealed that two V3 lineage groups had evolved in the parents. Group 1 was maintained with low variation in all three family members regardless of the clinical state or the length of infection, whereas group 2 was only present in symptomatic individuals and was more positively charged and diverse than group 1. Only virus isolates carrying the group 2 V3 sequences infected and induced syncytia in MT2 cells, a transformed CD4(+)-T-cell line. A statistically significant excess of nonsynonymous substitutions versus synonymous substitutions was demonstrated only for the group 2 V3 region. The data suggest that HIV-1 variants, possessing the more homogeneous group 1 V3 element and exhibiting the non-syncytium-inducing phenotype, persist in infected individuals independent of clinical status and appear to be more resistant to positive selection pressure.  (+info)

Identification of MaTu-MX agent as a new strain of lymphocytic choriomeningitis virus (LCMV) and serological indication of horizontal spread of LCMV in human population. (8/1248)

In this study we elucidated the molecular character of MaTu-MX, previously described as an unusual transmissible agent. Amino acid sequencing of peptides generated from a 58-kDa MX-related protein purified from MaTu human carcinoma cells allowed us to identify it as a nucleoprotein (NP) of lymphocytic choriomeningitis virus (LCMV). Northern blot analysis detected LCMV-specific RNAs in MaTu cells. Comparative immunoprecipitations showed cross-reactivity between NP of LCMV strain WE and MX NP. Using RT-PCR, we have cloned MX NP cDNA. According to sequence comparison, MX LCMV is as closely related to both LCMV strains WE and Armstrong as these strains are to one another. Based on this finding we propose that MX is a new strain of LCMV. We also showed that the stability of MX NP in MaTu cells is very high and that the virus is transmissible by cell-to-cell contact or by cell-free extract to human HeLa and monkey Vero cells, but not to human AGS, canine MDCK, mouse NIH 3T3, and hamster CHO cells. Finally, employing MX LCMV NP in immunoprecipitation and solid-phase radioimmunoassay, we found 37.5% prevalence of anti-LCMV antibodies in human sera, suggesting possible horizontal spread of the virus in the human population.  (+info)

The contactor has a tip portion at one end of the contactor to contact with the contact target, a base portion at another end of the contactor which is inserted in a through hole provided on the contact substrate in such a way that an end of the contactor functions as a contact pad for electrical connection at a surface of the contact substrate, and a spring portion provided between the tip portion and the base portion which produces a contact force when the contactor is pressed against the contact target.
A contact structure for establishing electrical connection with contact targets. The contact structure is formed of a contact substrate and a plurality of contactors. The contactor has an intermediate portion which is inserted in the through hole provided on the contact substrate in a vertical direction, a contact portion which is connected to the intermediate portion and positioned at one end of the contactor to function as a contact point for electrical connection with a contact target, and a base portion which is provided at other end of the contactor, and a spring portion having a cantilever shape upwardly inclined relative to the surface of the contact substrate and provided between the base portion and the intermediate portion.
Contact structures are formed by building a core structure on a substrate and over coating the core structure with a material that is harder or has a greater yield strength than the material of the core structure. The core structure may be formed by attaching a wire to the substrate and spooling the wire out from a spool. While spooling the wire out, the spool may be moved to impart a desired shape to the wire. The wire is severed from the spool and over coated. As an alternative, the wire is not over coated. The substrate may be an electronic device, such as a semiconductor die.
The present invention relates to coupler device, processing apparatus and method of processing a plurality of body-coupled communication signals which have been detected by using an electrode arrangement with a plurality of electrodes or electrode segments ( 40, 42; 40, 43 ). Respective transmission parameters of the body-coupled communication signals are estimated and at least one of a selecting and weighting processing is applied to the detected body-coupled communication signals based on the estimated transmission parameters. Then, the processed body-coupled communication signals are combined to generate a diversity output signal. Thereby, robustness against coupler misplacement and user convenience is increased in body-coupled or body-based communication systems.
Dec 19, 2016 , Atlanta, GA. The demand and the average time on the waiting lists for organ transplants are growing, while the supply of organs remains comparatively limited.. According to UNOS, the United Network for Organ Sharing, currently more than 121,480 people across the United States are waiting for an organ, while 30,970 people received transplants in 2015. In the same year, 6,648 people died on the transplant waitlist, while 6,702 were removed from the list after waiting so long that they became too sick to undergo transplant surgery.. A possible resolution to this problem is to increase the availability of organs. In the past, organs with a small risk of infection were often not chosen for transplant. After several transmissions of infectious diseases that occurred through transplants where these infections (or the risk) were not detected ahead of time, use of many more organs were discouraged because of problems with understanding the risk..

The reducing agent is dissolved uniformly or becomes a colloidal solution state if the reducing agent is not dissolved. A complexing agent is added to the plating bath as needed, and a plated member is treated with electroplating. Accordingly, eutectoid of the metal matrix and the reducing agent is formed on the plated member ...
Describing contact patterns is crucial to understanding infectious disease transmission dynamics and guiding targeted transmission mitigation interventions. Data on contact patterns in Africa, especially South Africa, are limited. We measured and compared contact patterns in a rural and urban community, South Africa. We assessed participant and contact characteristics associated with differences in contact rates. We conducted a cross-sectional study nested in a prospective household cohort study. We interviewed participants to collect information on persons in contact with for one day. We described self-reported contact rates as median number people contacted per day, assessed differences in contact rates based on participant characteristics using quantile regression, and used a Poisson model to assess differences in contact rates based on contact characteristics within age groups. We also calculated cumulative person hours in contact within age groups at different locations. We conducted 535 interviews
The potential for transmission of infectious diseases in the outpatient setting is an increasingly important concern as more (and more invasive) medical care is delivered outside of the hospital. This study begins the important task of developing a systematic approach to infection control for outpatient settings by providing a review of published reports of cases of infections acquired in outpatient settings. As the authors acknowledge, the conclusions that can be drawn are limited by biases that affect whether an infectious outbreak is reported, including, among others, the ease of documentation of specific organisms involved, the degree of interest in the circumstances or etiologic agent, and the number of persons involved. Further, information about the numbers and types of patients who did not develop the diseases being studied is not reported. Thus, this study does not permit conclusions regarding the frequency of outpatient transmission of infectious diseases, the specific infections that ...

On the technical side, I had some ideas. Wonder if they made sense and if any of these tools (apps) already exist:. One of the big tools in the response is transmission tracking and isolation. Going ahead this seems a common part of the response to any pandemic. But from reading the news this seems to be still done in a relatively primitive way. These days most everyone has a smartphone. With a combination of GPS and perhaps blue tooth shouldnt it be possible to create a list of potential contacts? This way, the moment a positive for an infection is detected (through a symptomatic case, or random screening etc.) instantaneously a list of probables for infection transmission could be generated and then triaged. Not sure how much damage reduction we already can do but surely for future pandemics this sort of thing can squelch the spread right at the start? Perhaps, GPS alone will generate a moving circle too large for this to make good use of; typical transmission tracking would want to only ...

Sasakian manifolds were first introduced in 1962. This books main focus is on the intricate relationship between Sasakian and Kähler geometries, especially when the Kähler structure is that of an algebraic variety. The book is divided into three parts. The first five chapters carefully prepare the stage for the proper introduction of the subject. After a brief discussion of G-structures, the reader is introduced to the theory of Riemannian foliations. A concise review of complex and Kähler geometry precedes a fairly detailed treatment of compact complex Kähler orbifolds. A discussion of the existence and obstruction theory of Kähler-Einstein metrics (Monge-Ampère problem) on complex compact orbifolds follows. The second part gives a careful discussion of contact structures in the Riemannian setting. Compact quasi-regular Sasakian manifolds emerge here as algebraic objects: they are orbifold circle bundles over compact projective algebraic orbifolds. After a discussion of symmetries of Sasakian

A method for testing and burning-in semiconductor components such as semiconductor dice on a semiconductor wafer, is provided. The method includes the step of providing all of the components on the wafer with resilient contact structures, such as metal pins having integral spring segments. The resilient contact structures are used to test the components to identify functional and non-functional components. Following this test, the resilient contact structures on the non-functional components are deformed, such that electrical communication with the non-functional components is prevented in a subsequent burn-in test. This permits the burn-in test to be performed using
A colonization is the usual presence of non-pathogenic and even potentially pathogenic microbes on the skin, in the nose, mouth, bowel, penile or vaginal mucosa, as a part of normal human flora, in the amount not harmful for the body - this is not an infection. An example is the presence of Lactobacilus acidophilus bacteria in the colon.. A contamination is the presence of germs which do not multiply, for example, in a contaminated (not infected)wound. Infected or septic wound contains multiplying microbes. Contamination also refers to presence of pathogenic microbes on medical equipment, in the water, food etc.. A carrier state is the non-usual presence of pathogenic microbes in the body, in the way not harmful for the carrier, but potentially dangerous for others, since the carrier is usually contagious. For example, if you have Staphylococcus aureus bacteria (a common cause of skin infections) in your nose, you may infect others, even if you alone never develop an infection.. An overgrowth of ...
The relative amount of transmission in I2 (ϕ) also has a large effect on ESS virulence (figure 1b). As the amount of transmission in I2 increases, the ESS virulence decreases, and the rate of decrease depends on the level of mortality that occurs in the I1 class. As the level of transmission in I2 and the disease mortality rate in the I1 class (ρ) approach zero, the ESS virulence goes to infinity (figure 1b). These results can be understood by realizing that for any fixed level of virulence (α), decreases in the transmission parameter ϕ reduce the fitness benefit of reaching the second class (I2), while increases in ρ both decrease the probability of reaching the second class and decreases the infectious period in the first class. Therefore, as both parameters reach zero, there is no benefit in reaching the second class and no cost to virulence in the first class. Thus, ESS virulence is very high and virulence will have a greater tendency to increase after introduction.. The effect of the ...
In this work we develop an experimental method to study interparticle force transmission in 3D. An initial 2D study of volumetric data for commercially available polyethylene fluorescent microspheres shows that three-dimensional effects play a significant role in deformation of real granular assemblies. This highlights the need for more experimental work to validate existing numerical models and motivate further development of theory and models describing real 3D granular media. A full 3D analysis method is described where volumetric images are captured via confocal microscopy and the displacement fields for each particle are determined using digital volume correlation (DVC). This data is then used to determine the average strain in each particle as well as the assemblys fabric (geometric descriptors of particles and contacts) which are in turn used for the Granular Element Method (GEM) to determine interparticle forces.

Zika virus (ZIKV) emerged in Latin America and the Caribbean (LAC) region in 2013, with serious implications for population health in the region. In 2016, the World Health Organization declared the ZIKV outbreak a Public Health Emergency of International Concern following a cluster of associated neurological disorders and neonatal malformations. In 2017, Zika cases declined, but future incidence in LAC remains uncertain due to gaps in our understanding, considerable variation in surveillance and the lack of a comprehensive collation of data from affected countries. Our analysis combines information on confirmed and suspected Zika cases across LAC countries and a spatio-temporal dynamic transmission model for ZIKV infection to determine key transmission parameters and projected incidence in 90 major cities within 35 countries. Seasonality was determined by spatio-temporal estimates of Aedes aegypti vectorial capacity. We used country and state-level data from 2015 to mid-2017 to infer key model
Existing estimates of the basic reproduction number, R0, for human schistosomes are mostly in the range 1-4, implying that schistosomes should be relatively easy to eliminate from endemic areas, which is contrary to practical experience. An estimate of R0 for a site in Zimbabwe is obtained here using a mathematical model explicitly incorporating two features believed to be epidemiologically significant; age-dependent exposure and acquired immunity. Parameter estimates are, as far as possible, obtained independently, but the coefficients representing man-snail and snail-man transmission, as well as parameters representing effects of acquired immunity, must be estimated indirectly by fitting the model to field data. Heterogeneity in human exposure and contamination is crudely incorporated by considering `wormy and non-wormy fractions of the population. The results suggest R0 to be in the range 4-5 or more, higher than previous estimates and despite only moderate levels of infection at this site. ...
Author Summary Resistance of influenza to common antiviral agents carries the possibility of causing large morbidity and mortality through failure of treatment and should be taken into account when planning public health interventions focused on stopping transmission. Here we present a mathematical model of influenza transmission which incorporates heterogeneous contact structure and stochastic transmission events. We find scenarios when treatment either induces large levels of resistance or no resistance at identical values of transmission rates depending on the number initially infected. We also find, contrary to previous results, that targeted treatment causes more resistance at lower treatment levels than non-targeted treatment. Our results have important implications for the timing and distribution of antivirals in epidemics and highlight important differences in how transmission is modeled and where assumptions made in previous models cause them to lead to erroneous conclusions.

egg. Covid has proved rather less lethal than I thought it might in March last year: as the Doomlord rightly notes, that was a time of radical uncertainty, uncertainty that diminished, as it tends to, with time. We should count our blessings.. Yet the insistence by some here that any government response was an over-reaction is as nonsensical as was the Economists Letter that, on its face, denied the existence of any trade-offs between economic activity and the Covid suppression. There are obvious trade-offs: we would never abandon all economic activity for the sake of suppressing a disease, and despite the inflated claims of some lockdown opponents, we never did. Moreover there are dynamic (ie, inter-temporal) trade-offs: the price of some economic activity today, with the risk of infection transmission, was the likelihood of more wide-spread infection tomorrow. The point the Economists Letter should have made was that, in the view of its authors, the benefits of continued steps toward ...
In this paper, we investigate a disease transmission model of SIRS type with latent period τ≥0 and the specific nonmonotone incidence rate, namely, For the basic reproduction number R0>1, applying monotone iterative techniques, we establish sufficient conditions for the global asymptotic stability of endemic equilibrium of system which become partial answers to the open problem in [Hai-Feng Huo, Zhan-Ping Ma, Dynamics of a delayed epidemic model with non-monotonic incidence rate, Commun. Nonlinear Sci. Numer. Simul. 15 (2010) 459-468]. Moreover, combining both monotone iterative techniques and the Lyapunov functional techniques to an SIR model by perturbation, we derive another type of sufficient conditions for the global asymptotic stability of the endemic equilibrium ...
Epidemiology strongly parallels the study of ecology, primarily being concerned with the incidence, distribution, reproduction and persistence of species. The spread of disease, or its transmission, is arguably the most important incident studied in epidemiology, underpinning a pathogens ability to reproduce and persist within a host population. However, observations of individual transmission events are often impossible to observe directly, making variation in this process difficult to study. This has resulted in a great deal of epidemiological theory being based on homogenous transmission of disease through host populations. Understanding disease transmission as a heterogeneous process requires an appreciation of the ecological dynamics determining a pathogens ability to transmit. In this thesis a cross-disciplinary approach is taken to examine the ecological dynamics that may affect disease transmission at different ecological scales. In Chapter 2 I review empirical evidence in support of ...
We give a survey of results on global stability for deterministic compartmental epidemiological models. Using Lyapunov techniques we revisit a classical result, and give a simple proof. By the same methods we also give a new result on differential susceptibility and infectivity models with mass action and an arbitrary number of compartments. These models encompass the so-called differential infectivity and staged progression models. In the two cases we prove that if the basic reproduction ratio R0 \leq 1, then the disease free equilibrium is globally asymptotically stable. If R0 | 1, there exists an unique endemic equilibrium which is asymptotically stable on the positive orthant.

Abstract: The threat of new or emerging diseases, such as avian influenza, has prompted many researchers to construct detailed predictive models of infectious disease transmission between humans in order to advise healthcare policy. At the heart of many of these models, however, are crude assumptions regarding the mixing and contact rates between individuals. Here, I will present the results from a diary-based contact survey which describes how often individuals encountered others, as well as the level of intimacy and the social context of the encounter. Simulations demonstrate the important characteristics of this data for transmission of infection. see: DIMACS Computational and Mathematical Epidemiology Seminar Series 2006 - 2007 ...

The transmission of infections is once again in the forefront of worldwide concerns. The current Ebola virus outbreak which started in Africa has killed many people and the future of this epidemic is unknown. When studying infectious disease transmission and prevention, the hospital as a building is a virtual guinea pig. The high rates of patient deaths due to healthcare-associated infections (HAIs) indicate that this guinea pig is very sick indeed. Why is the hospital physical environment a place where infections flourish? Hospitals are shelters . . .
Individuals living in communities more remote at baseline had lower travel rates compared with less remote villages (adjusted odds ratio [OR] = 0.51; 95% confidence interval [CI] = 0.38, 0.67). Our model predicts that less remote villages are, therefore, at increased disease risk. Though road building and travel increased for all communities, this risk differential remained over 10 years of observation. Our transmission model also suggests that travelers and nontravelers have different roles in disease transmission. Adults travel more than children (adjusted OR = 1.73; 95% CI = 1.30, 2.31) and therefore disseminate infection from population centers to rural communities. Children are more likely than adults to be infected locally (attributable fraction = 0.24 and 0.09, respectively) and were indirectly affected by adult travel patterns ...
Phylogenetic clustering of HIV sequences from a random sample of patients can reveal epidemiological transmission patterns, but interpretation is hampered by limited theoretical support and statistical properties of clustering analysis remain poorly understood. Alternatively, source attribution methods allow fitting of HIV transmission models and thereby quantify aspects of disease transmission. A simulation study was conducted to assess error rates of clustering methods for detecting transmission risk factors. We modeled HIV epidemics among men having sex with men and generated phylogenies comparable to those that can be obtained from HIV surveillance data in the UK. Clustering and source attribution approaches were applied to evaluate their ability to identify patient attributes as transmission risk factors. We find that commonly used methods show a misleading association between cluster size or odds of clustering and covariates that are correlated with time since infection, regardless of their
