This declaration was based on strong indications that, worldwide, influenza is transitioning toward seasonal patterns of transmission. (uspharmacist.com)
Out-of-season 2009 H1N1 outbreaks are no longer being seen in most countries, and the intensity of transmission is lower than that reported in 2009 and early 2010. (uspharmacist.com)
Previous research on the pandemic found that environmental factors, timing of the end school holidays, population sizes and air travel contributed to its spread, but this new research has found that transmission occurred primarily over short distances and that school age children may have catalysed the spread.

The epidemiological mechanisms behind the W-shaped age-specific influenza mortality during the Spanish influenza (H1N1) pandemic 1918-19 have yet to be fully clarified. (hindawi.com)
The present study aimed to develop a formal hypothesis: tuberculosis (TB) was associated with the W-shaped influenza mortality from 1918-19. (hindawi.com)
Analyzing the data (i), we found that the W-shaped pattern was not only seen in mortality but also in the age-specific case fatality ratio, suggesting the presence of underlying age-specific risk factor(s) of influenza death among young adults. (hindawi.com)
The data (iii) were analyzed by employing the age-period-cohort model, revealing harvesting effect in the period function of TB mortality shortly after the 1918-19 pandemic. (hindawi.com)

New analysis of the 2009 H1N1 influenza pandemic in the US shows that the pandemic wave was surprisingly slow, and that its spread was likely accelerated by school-age children. (cam.ac.uk)
The most detailed analysis to date of the spread of the H1N1 2009 pandemic influenza virus, known informally as 'swine flu', has found that short-range travel was likely the primary driver for the 2009 pandemic in the United States, in contrast with popularly accepted views on the way diseases spread.

The study, based on data gathered from health insurance claims made throughout 2009, found that international air travel, which was previously thought to be important in the pandemic, played only a minor role in its spread within the US. (cam.ac.uk)
According to this new analysis, school-age children accelerated the spread of the pandemic, which was transmitted over short distances, in contrast with widespread reports at the time linking the pandemic to international air travel and population density. (cam.ac.uk)
The H1N1 influenza virus spread rapidly around the globe in 2009 after it was first identified in Mexico. (cam.ac.uk)
There is so little detailed analysis of the way in which pandemics spread - so much of the current thinking is based on opinion and presumption," said Dr Julia Gog of Cambridge's Department of Applied Mathematics and Theoretical Physics, who led the research. (cam.ac.uk)
It's remarkable that in an era of widespread air travel and regional ground transport that this pandemic spread so slowly," said Dr Gog. (cam.ac.uk)
During a flu pandemic, one way to prevent the spread of the flu is to have those who are sick stay home. (cdc.gov)
Researchers explored these questions this past spring in Texas, the second state to have confirmed person-to-person spread of pandemic H1N1 2009 flu. (cdc.gov)
Pandemic influenza A (H1N1) virus emerged in Mexico in early 2009 and rapidly spread worldwide. (cambridge.org)
The CDC has issued interim recommendations for controlling the spread of H1N1 influenza in health care settings. (medscape.com)

What patient factors were predictors of adverse outcomes among children diagnosed with h1n1 during the 2009 pandemic? (medscape.com)

Influenza virus subtypes H1 and H3 of diverse lineages are endemic in swine and are globally widespread. (cdc.gov)
This is of greater concern in parts of Southeast Asia, where the population density is high, influenza is less seasonal, human-animal contact is common and avian influenza is still endemic. (psu.edu)

BACKGROUND: The impact of pandemic (H1N1) 2009 influenza on immunocompromised patients in western countries has been described, but reports from pediatric patients in the Middle East or Arab countries are deficient. (edu.lb)

However, the global impact of this new pandemic remains uncertain. (elsevierpure.com)
