Global circulation of influenza viruses

The global anxiety and a significant threat to public health due to the current COVID-19 pandemic reiterate the need for active surveillance for the zoonotic virus diseases of pandemic potential. Influenza virus due to its wide host range and zoonotic potential poses such a significant threat to public health. Click on the article title to read more. Introduction. Antiviral agents are part of the initial response plans for pandemic influenza and play a key role in protecting high‐risk populations from seasonal influenza. 1 , 2 , 3 In recent years, the widespread circulation of seasonal A(H3N2) viruses resistant to the aminoadamantanes and seasonal A(H1N1) viruses resistant to the neuraminidase inhibitor oseltamivir has been observed.

Influenza surveillance data from recent years shows co-circulation of influenza B viruses from both lineages in the United States and around the world. Understanding the spatiotemporal patterns of emergence and circulation of new human seasonal influenza virus variants is a key scientific and public health challenge.

A pandemic can occur when a new and very different influenza A virus emerges that both infects people and has the ability to spread efficiently between people. The global anxiety and a significant threat to public health due to the current COVID-19 pandemic reiterate the need for active surveillance for the zoonotic virus diseases of pandemic potential. Influenza virus due to its wide host range and zoonotic potential poses such a significant threat to public health.

Some skeptics suspected that influenza was simply reclassified as covid, while many journalists and ‘fact checkers’ claimed influenza was suppressed by face masks and lockdowns. 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.
