Episode notes
Bird Flu's Mammalian Shift
- The H5N1 bird flu, widespread in birds, is now infecting US dairy cows and some humans.
- Two human cases have an untraceable source, raising concerns about human-to-human transmission.
Asymptomatic Spread of Bird Flu
- A study found 7% of dairy farm staff had H5N1 antibodies despite no symptoms, suggesting undetected spread.
- This makes monitoring infection severity and transmission potential challenging.
COP29 Funding Shortfall
- The COP29 climate summit deal secured only $300 billion yearly for poorer nations, falling short of the $1.3 trillion requested.
- This inadequate funding hinders climate action and discourages carbon-cutting plans.
