A total of 61 cases of psittacosis in man were reported from 22 states during 1965, 8 cases more than in 1964. Parakeets were the most frequently mentioned probable source of human infection, with pigeons being next in frequency. Two turkey ornithosis outbreaks, both associated with low human morbidity, were reported during the year. One occurred in Minnesota causing three human infections and the other occurred in Virginia, resulting in one human case.
