How Durable is the disease?
According to WHO, the virus is killed by heat (56 deg C for 3 hours or 60 deg C for 30 minutes) and common disinfectants, such as formalin and iodine compounds. The virus can survive, at cool temperatures, in contaminated manure for at least three months. In water, the virus can survive for up to four days at 22 deg C and more than 30 days at 0 deg C. For the highly pathogenic form, studies have shown that a single gram of contaminated manure can contain enough viruses to infect 1 million birds.
