In the 1957 "Asian flu" and 1968 "Hong Kong flu" pandemics, flu strains were caused by reassortment between an avian virus and a human virus. [ 2 ] [ 3 ] In addition, the H1N1 virus responsible for the 2009 swine flu pandemic has an unusual mix of swine, avian and human influenza genetic sequences.
Americans are in the throes of flu season in large swaths of the country. Data − from traces in wastewater to hospitalizations − show higher levels of flu virus circulating in most of the U.S ...
The findings are based on the analysis of samples collected in Europe during the 1918 pandemic.
The avian virus is inactivated more quickly in manure, but can survive for up to two weeks in feces on cages. Avian influenza viruses can survive indefinitely when frozen. [ 57 ] Influenza viruses are susceptible to bleach, 70% ethanol, aldehydes, oxidizing agents, and quaternary ammonium compounds.
A quadruple whammy of viruses – flu, COVID, norovirus, and respiratory syncytial virus, or RSV – is hitting the U.S. as the year comes to a close. The Centers for Disease Control and ...
