Most discussions acknowledge the likelihood of lab leaks contributing to viral re-emergence, showing general agreement with the article's themes.
Posts demonstrate high curiosity, referencing multiple historical cases and debating lab leak origins, indicating strong engagement.
Many discussions delve into scientific analyses, historical context, and implications for future research, revealing deep involvement.
These social discussions highlight significant concerns regarding viral origins, public health risks, and the need for better scientific transparency, indicating high influence.
Abstract in brief
- The 1977 reemergence of H1N1 influenza after 20 years was likely due to a lab strain accidentally released, which appeared to lack decades of evolution.
- Using viral samples with unrealistic dates in evolutionary analyses can lead to biased divergence time estimates and higher uncertainty.
- Reanalyzing the data suggests the 1977 virus circulated for about a year before detection, but pinpointing its geographic source remains challenging, highlighting the need for better methods to handle such data.]

@guillaume512312 Incidentally the Spanish flu virus took a 20-year break right after the new H2N2 virus caused a pandemic in 1957—and re-emerged in 1977. Fascinating stuff, rich with clues about viral emergence & extinction. I'm surprised no one is looking at all this. https://t.co/yodXX3HE3q

@SOwieka Nie wspominając o ponownym pojawieniu się H1N1 w maju 1977r (najpierw w Chinach, potem w Rosji). Wycieki z lab. to w Chinach już tradycja. https://t.co/kznxvwwUUo
@strollisgoat @NateSilver538 While I agree lab leak cause is low probability in this case, it has happened before. For example: H1N1 flu pandemic of 1977 https://t.co/S8Y4ysdirl 2007 United Kingdom foot-and-mouth outbreak https://t.co/OCaGnnbUEh 2019 brucellosis outbreak in China https://t.co/nGvWi8eBsh
@ejames_c I also knew this had happened before - 1977 Russian Flu was very likely a lab leak (in China, not sure if Wuhan). So, I knew the fact that the origin was next to a virology institute "concentrated a lot of probability mass" on the hypothesis of a leak. https://t.co/VaNdB3Ar9s
@BeijingPalmer "impossible to ever actually verify" it was verified in cases of SARS and H1N1, both of which were leaks from chinese labs 'impossible' seems to be a way of papering over, "labs won't share records" https://t.co/TdHdMIPTbe https://t.co/kPJIRN1wcf
