Surveillance Psittacosis is a reportable condition in most states. Trends Annual incidence varies considerably because of periodic outbreaks. A decline in reported cases since 1988 may be the result of improved diagnostic tests that distinguish C.psittaci from more common C. pneumoniae infections. Challenges Diagnosis of psittacosis can be difficult. Antibiotic treatment may prevent an antibody response, thus limiting diagnosis by serologic methods.
Infected birds are often asymptomatic.
Tracebacks of infected birds to distributors and breeders often is not possible because of limited regulation of the pet bird industry. Opportunities Characterize new and rapid diagnostic tests for human and avian psittacosis, and determine value of screening flocks for avian psittacosis to prevent human infection.
