H5N1 avian influenza spilling over to cows and cats

A CDC report indicates H5N1 avian influenza is transmitting from birds to domestic cattle and cats, with potential cow-to-cow transmission noted. Such developments suggest new transmission pathways to humans, especially through consumption of raw milk. The study underscores the virus’s spread in affected cattle herds and a high incidence of severe disease and mortality in cats exposed to infected milk. Consequently, caution is advised against consuming raw milk and exposing cats to it.

H5N1 flu virus (bird flu) vaccine development and availability

The USA faces a growing bird flu outbreak caused by the H5N1 virus, with potential human infection risks but no confirmed human-to-human transmission yet. While the CDC monitors the situation, they’ve prepared by stockpiling H5N1 vaccines from manufacturers like Sanofi and GSK. However, the current vaccine reserves are limited and primarily for healthcare workers, with mass production waiting until a specific pandemic strain is identified. Furthermore, vaccine production could be challenged by reduced chicken egg availability due to the outbreak, prompting research into egg-less vaccine production methods.

Bird flu outbreaks — what are the scientific facts

An emerging bird flu outbreak involves the H5N1 subtype, with the potential of infecting humans. Currently, 48 states reported outbreaks in birds, but only two human cases, one mild, were confirmed. While there’s no immediate concern for a pandemic, health authorities remain vigilant, and vaccines are available. The press may be reacting strongly to the situation.

FDA approves first vaccine to prevent H5N1 avian influenza
