There is no known treatment for the polyomavirus disease.
Following strict hygiene methods, such as disinfecting nest boxes, cages, incubators or utensils, can help ensure your bird does not get infected with the polyomavirus. The virus, however, is resistant to most disinfectants; use oxidizers like chlorine beach instead. Aviaries and pet stores should also regularly screen for the virus. And new birds should be quarantined to ensure they do not carry the disease.
Vaccination is available, but its effectiveness has still not be proven. The vaccine is given as a double dose to young birds. The first dose is given at four weeks of age, and second dose is given between six to eight weeks of age.
Adult birds also receive a double dose of vaccination; the second dose given about two to four weeks after the first. A booster dose of the vaccine is then required yearly.
