I haven’t made a mistake in this case. You haven’t shown how my claim is wrong.
You:
“It took the human H1N1 virus 90 years to go extinct (see below).”
“H1N1pdm09 is swine flu…”
Reality:
“Influenza A (H1N1) pdm09 emerged as a major public health problem in 2009. The virus has evolved since then and has acquired several mutations that are epidemiologically important. Viral hemagglutinin (HA) protein is crucial determinant for virus entry, antigenicity, and virulence. The information regarding amino acid substitutions in HA protein of viruses circulating in India during 2017 is lacking. We sequenced HA gene of Influenza A (H1N1) pdm09 detected in Central India and compared the amino acid sequences with present vaccine component and contemporary Influenza A (H1N1) pdm09 sequences. We observed 7 amino acid changes of which two (T508A and I510T) were novel to Central Indian strain.”
H1N1pdm09, which you’re desperately trying to obfuscate as mere “swine flu,” is infecting and being isolated from humans in 2019, thus also fitting your “human H1N1 virus” definition, which you falsely claim is extinct.
Or are you claiming that these Indian patients in Madhya Pradesh are swine?
