Psittacosis—also known as parrot fever, and ornithosis—is a zoonotic infectious disease in humans caused by a bacterium called Chlamydia psittaci and contracted from infected parrots, such as macaws, cockatiels, and budgerigars, and from pigeons, sparrows, ducks, hens, gulls and many other species of birds.
Chlamydia psittaci is a lethal intracellular bacterial species that may cause endemic avian chlamydiosis, epizootic outbreaks in other mammals, and respiratory psittacosis in humans. Potential hosts include feral birds and domesticated poultry, as well as cattle, pigs, sheep, and horses.
Humans commonly catch parrot fever by breathing in the dust from an infected bird’s secretions, according to the US Centers for Disease Control and Prevention. People can also get sick if a bird ...
The 1929–1930 psittacosis pandemic, also known as the psittacosis outbreak of 1929–1930 and the great parrot fever pandemic, [2] was a series of simultaneous outbreaks of psittacosis (parrot fever) which, accelerated by the breeding and transportation of birds in crowded containers for the purpose of trade, was initially seen to have its origin in parrots from South America.
Vendors selling birds including parrots, cockatoos, lovebirds and parakeets, must provide written information on psittacosis and avian chlamydiosis and post a sign with information. Infected pet ...
[5] [6] [7] Human infection with animal influenza viruses is rare, as they do not transmit easily to or among humans. [8] However, avian and swine influenza viruses in particular possess high zoonotic potential, [9] and these occasionally recombine with human strains of the flu and can cause pandemics such as the 2009 swine flu.

The most common era or years that feral parrots were released to non-native environments was from the 1890s to the 1940s, during the wild-caught parrot era. In the psittacosis "parrot fever" panic of 1930, "One city health commissioner urged everyone who owned a parrot to wring its neck. People abandoned their pet parrots on the streets." [30]
Humans have become infected while visiting forested areas and are believed to be responsible for helping the virus make its way to towns and cities, but person-to-person transmission hasn't been ...
