There is no definitive treatment for birds with polyomavirus infection, other than supportive care. Birds with mild hemorrhaging might benefit from vitamin K injections and supportive veterinary care. Often, the disease progresses so quickly that no treatment will be effective.
Several herbs such as sage, garlic, thyme, echinacea and oregano, possess anti-coccidial properties against Eimeria species, which reduce oocyst excretions from infected birds.
Foods to offer: seed, millet, pellets, some fresh fruit, or easily digestible human foods such as mashed ripe bananas, applesauce, strained or soft vegetables such as peas or vegetables, infant rice cereal or baby food, oatmeal, or ground up pellets mixed with fruit juice.
