How many days before the virus is no longer viable in bird droppings?
The viability of AI in feces is generally dependent on three things: • temperature of environment • humidity of environment • exposure to sunlight Generally, influenza viruses survive for up to 7 days at 70°F under “good” conditions (high humidity and no sunlight), but they can survive longer in colder temperatures. Experimentally, infected chicken feces can remain positive for virus through 35 days when stored wet at 4°C (~ 39°F) and not exposed to sunlight.
