Scientists uncover the antigenic patterns of the recent influenza A (H3N2) virus

Scientists uncover the antigenic patterns of the recent influenza A (H3N2) virus | Influenza | Scoop.it
The human influenza A (H3N2) virus was widespread in many countries in the 2014-2015 winter season, causing more morbidity and mortality. Through an antigenic modeling, it was discovered that the recent H3N2 viruses constitute two distinct antigenic clusters, which may account for its disease burden in the 2014-2015 winter season.

1977 H1N1 influenza virus is not relevant to the gain of function debate

A new analysis shows that the reappearance of the 1997 H1N1 virus has little relevance to the gain-of-function debate.

Global circulation patterns of seasonal influenza viruses vary with antigenic drift : Nature : Nature Publishing Group

Global circulation patterns of seasonal influenza viruses vary with antigenic drift : Nature : Nature Publishing Group | Influenza | Scoop.it
Understanding the spatiotemporal patterns of emergence and circulation of new human seasonal influenza virus variants is a key scientific and public health challenge. The global circulation patterns of influenza A/H3N2 viruses are well characterized, but the patterns of A/H1N1 and B viruses have remained largely unexplored. Here we show that the global circulation patterns of A/H1N1 (up to 2009), B/Victoria, and B/Yamagata viruses differ substantially from those of A/H3N2 viruses, on the basis of analyses of 9,604 haemagglutinin sequences of human seasonal influenza viruses from 2000 to 2012. Whereas genetic variants of A/H3N2 viruses did not persist locally between epidemics and were reseeded from East and Southeast Asia, genetic variants of A/H1N1 and B viruses persisted across several seasons and exhibited complex global dynamics with East and Southeast Asia playing a limited role in disseminating new variants. The less frequent global movement of influenza A/H1N1 and B viruses coincided with slower rates of antigenic evolution, lower ages of infection, and smaller, less frequent epidemics compared to A/H3N2 viruses. Detailed epidemic models support differences in age of infection, combined with the less frequent travel of children, as probable drivers of the differences in the patterns of global circulation, suggesting a complex interaction between virus evolution, epidemiology, and human behaviour.

Ahead of Print -Effect of Live Poultry Market Closure on Avian Influenza A(H7N9) Virus Activity in Guangzhou, China, 2014 - Volume 21, Number 10—October 2015 - Emerging Infectious Disease journal -...

We assessed the effect of closing live poultry markets in China on influenza A(H7N9) virus detection and viability. Intensive sampling was carried out before, during, and after a 2-week citywide market closure; the markets were cleaned and disinfected at the beginning of the closure period. Swab samples were collected at different sites within the markets and tested for H7N9 by real-time reverse transcription PCR and culture. During the closure, H7N9 viral RNA detection and isolation rates in retail markets decreased by 79% (95% CI 64%–88%) and 92% (95% CI 58%–98%), respectively. However, viable H7N9 virus could be cultured from wastewater samples collected up to 2 days after the market closure began. Our findings indicates that poultry workers and the general population are constantly exposed to H7N9 virus at these markets and that market closure and disinfection rapidly reduces the amount of viable virus.
