🦜💩 Bird poo surveillance reveals global flu hotspots
A new study tracked avian influenza by analysing bird guano in 10 countries. It uncovered high H5N1 diversity, signs of antiviral resistance, & early circulation of strains later found in humans.

Why epidemic assumptions can matter so much…
An ongoing scientific question about the early dynamics of COVID is precisely when the first wave peaked in the UK – when did infections themselves actually start declining?
