What is being done in countries that have bird flu cases?
Most of the countries are working with WHO/OIE/FAO to attempt accurate surveillance and reporting with culling of large populations of infected and exposed poultry (chickens, ducks, turkeys).
Those countries with cases of human bird flu are trying to isolate and quarantine (mostly via hospitalization) the infected and potentially infected cases.
They are sending test samples to reference labs for verification of infections with the H5N1. They are utilizing antiviral treatments and hospital intensive care therapy as indicated and available.
