We have detected avian H3N8 viruses in poultry. These viruses are genetically similar to recent human H3N8 cases in China. /1
wwwnc.cdc.gov/eid/article/28… So far no fatal human H3N8 case was reported before. And the detected H3N8 virus does not seem to be fully adapted to human. But many of us are serological naïve to this avian H3N8. /2

Does vaccination affect intra-host SARS-CoV-2 diversity? Do different variants have different abilities to explore sequence space?

Here is our @HKU_SPH @GuHaogao @ahmedaquadeer PREPRINT to answer these questions:
researchsquare.com/article/rs-133… To address these, we deep sequenced samples from vaccinated or unvaccinated COVID-19 patients infected by different variants (VOCs vs non-VOCs).

For the effect of vaccination, we found:
1. The nucleotide diversity between vaccinated and unvaccinated are similar.

Our report of SARS-CoV-2 in pet hamsters in published by #Lancet now.

Key findings：
1. The diversity of delta virus in hamsters is more diverse than expected. It might circulate in hamsters for a few months. /1 2. Multiple human clusters were found (blue arrows）suggesting that there were more than one hamsters to human transmission in this outbreak.
3. The hamster virus is still transmissible between humans. /2
