The influenza A(H1N1) pdm09 virus, which caused a human pandemic in 2009, contained genetic material from viruses that circulated in pigs, birds and humans in the 1990s and 2000s, hence its name. However, it currently circulates seasonally in humans and is different from those viruses that are common in pigs.
According to the head of the Influenza Research Institute, there are no particular differences in the course or consequences between the two strains of the influenza virus.
— For an ordinary person, in general, they are no different. Influenza caused by the A(H3N2) virus occurs with typical manifestations, and sometimes with atypical ones – it can masquerade as any other acute respiratory viral infection. It is impossible to determine by eye that the disease is caused by the influenza virus A, B, or any particular strain. Regarding the high mortality rate of influenza A (H3N2), everything is also ambiguous, it depends on various reasons. When swine flu dominated last season, although it was not swine, they also talked about off-scale mortality, added Dmitry Lioznov.
