In 1967 a total of 41 human cases of psittacosis were reported to the National Communicable Disease Center (NCDC). This was 9 cases fewer than in 1966 . Psittacosis surveillance reports were received on 38 of the 41 cases. Parakeets and pigeons were the most frequently mentioned probable sources of infection. The greatest risk of exposure was among pet bird owners. As in 1966, no chicken, turkey, or other avian ornithosis outbreaks were reported in 1967.
