AIDS1
- Viral load monitoring for HIV is of particular interest in the treatment of people with HIV, as this is continually discussed in the context of management of HIV/AIDS. (wikipedia.org)
Infectious dose4
- The viral load is a measure of how bright the fire is burning in an individual, whereas the infectious dose is the spark that gets that fire going," says Edward Parker at the London School of Hygiene and Tropical Medicine. (newscientist.com)
- Two basic virological concepts have gotten a lot of attention recently-the "infectious dose" and the "viral load" of SARS-CoV-2. (medicalxpress.com)
- Where does the uncertainty on viral loads and infectious dose leave us? (medicalxpress.com)
- Studying viral loads and the infectious dose will likely be important to make better decisions for health care providers. (medicalxpress.com)
Monitoring2
- Ct values or similar viral load data should be regularly reported to public health officials by testing centers and incorporated into monitoring programs. (medrxiv.org)
- Monitoring Treatment Effectiveness: Regular viral load testing is performed after initiating ART to monitor treatment response. (worldhivday.org)
COVID3
- However, in the case of covid-19, it doesn't necessarily follow that a higher viral load will lead to more severe symptoms. (newscientist.com)
- For instance, health workers investigating the covid-19 outbreak in the Lombardy region of Italy looked at more than 5,000 infected people and found no difference in viral load between those with symptoms and those without. (newscientist.com)
- For COVID-19, that means how many viral genomes are detected in a nasopharyngeal swab from the patient. (medicalxpress.com)
Virus9
- Although it is not commonly seen, it is possible to have an undetectable human immunodeficiency virus ( HIV ) load without treatment . (medicinenet.com)
- Undetectable viral load means the virus is dormant inside a small number of cells called viral reservoirs in the body. (medicinenet.com)
- In addition to antibody testing, human immunodeficiency virus (HIV) tests identify viral RNA. (medicinenet.com)
- If your viral load is undetectable, it suggests you have less human immunodeficiency virus (HIV) in your body. (medicinenet.com)
- Viral load and heterosexual transmission of human immunodeficiency virus type 1. (nih.gov)
- We examined the influence of viral load in relation to other risk factors for the heterosexual transmission of human immunodeficiency virus type 1 (HIV-1). (nih.gov)
- The viral load is the amount of a specific virus in a test sample taken from a patient. (medicalxpress.com)
- The viral load reflects how well a virus is replicating in an infected person. (medicalxpress.com)
- Not only from a viral evolutionary perspective but from a long-term damage one, since most proteins in this virus have multiple purposes and can induce long-term changes. (substack.com)
Clinical1
- The hypothesis of Opt4Kids was that point-of-care viral load testing and early referral for drug resistance testing would speed up clinical decision-making resulting in improved treatment outcomes among children with HIV. (aidsmap.com)
Ribonucleic1
- Main outcome measures Ribonucleic acid (RNA) viral load measured in respiratory, stool, serum, and urine samples. (bmj.com)
Initiation2
- Thus, the most important use of the viral load is to monitor the effectiveness of therapy after initiation of ART. (hiv.gov)
- By regularly assessing viral load, healthcare professionals can make informed decisions regarding treatment initiation, adjustment, and prevention strategies. (worldhivday.org)
Diagnosis1
- The HIV-infected population can be described by five component measures, depending on what information is available on the level of care, viral load, and diagnosis. (cdc.gov)
Strains2
- Crimean-Congo hemorrhagic fever (CCHF) is a tick- probe compatible with all known CCHFV strains was not borne viral zoonosis that occurs widely in Africa, Asia, possible. (cdc.gov)
- They identified antibodies that neutralized 100 percent of strains drawn from the major viral subtypes. (medindia.net)
Plasma2
- The viral load of HBV DNA in infected plasma samples showed a significant alteration in the biofield treated group as compared to control. (longdom.org)
- Additionally, viral load count of HCV RNA in infected plasma samples was significantly reduced by 67% in the biofield treated group as compared to control. (longdom.org)
Healthcare providers1
- People with HIV should consult their healthcare providers to identify an appropriate testing plan for viral load. (medicinenet.com)
Treatment9
- Can You Have Undetectable Viral Load Without Treatment? (medicinenet.com)
- According to HIV treatment guidelines in the United States, viral load should be evaluated every three to four months. (medicinenet.com)
- A viral load test is needed to guide treatment decisions. (medlineplus.gov)
- #AskTheHIVDoc: Care and Treatment What is a viral load blip? (greaterthan.org)
- Causes of viral rebound can include drug resistance, poor adherence to an HIV treatment regimen or interrupting treatment. (aidsmap.com)
- The WHO 2003 guidelines for the use of ART initially did not recommend viral load (VL) testing as a necessary component of treatment programs. (biomedcentral.com)
- Typically, HCV viral loads are checked during treatment at weeks 4, 8, 12, and 24, and then every 3 months after the conclusion of treatment. (medscape.com)
- Initiating Treatment: Viral load testing is crucial when deciding to start ART. (worldhivday.org)
- Rising viral load levels over time indicate treatment failure, and additional tests are conducted to assess potential drug resistance and guide treatment modification. (worldhivday.org)
Dynamics2
People2
- The report, Knowledge is power , reveals that although the number of people living with HIV who are virally suppressed has risen by around 10% in the last three years, reaching 47% in 2017, 19.4 million people living with HIV still do not have suppressed viral loads. (unaids.org)
- When you're talking about your viral load, people always ask if it goes up should I be worried, when should I investigate changing medications, those kinds of things. (greaterthan.org)
Predictor1
- This means that the viral load alone is not a clear predictor of disease outcome. (medicalxpress.com)
