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.
Dozens of captive animal species have been found infected or proven able to be experimentally infected with SARS-CoV-2, the virus that causes COVID-19. The virus has also been found in over a dozen wild animal species. Most animal species that can get the virus have not been proven to be able to spread it back to humans.
In the winter of 1929–1930, a psittacosis pandemic spread across the United States and Europe. Its mortality rate was 20% and as high as 80% for pregnant women. The disease's spread was eventually attributed to exposure to Amazon parrots imported from Argentina.
Here's how long it typically takes for symptoms to start.
At least one person in Denmark got parrot fever from a pet bird. Of the 15 other cases with available exposure information, 12 said they had contact with wild birds primarily through bird feeders.
After the latency period (but before clinical infection) the infected person can transmit the disease without signs of any symptoms. Such infection is called subclinical infection. Incubation period (also known as the latent period or latency period ) is the time elapsed between exposure to a pathogenic organism, a chemical, or radiation , and ...
There is no evidence of novel coronavirus transmission through food, food containers or food packaging. The vast majority of infections occur due to close contact with infectious patients.
Locally, they are considered as pests for feeding on crops, and are hunted for food or sport. [28] The current population is estimated to be in the range of 10,000 to 20,000. [25] [30] An example of the displacement of golden parakeets by habitat loss comes from the building of the Tucuruí Dam, Pará, from 1975 to 1984. More than 35,000 forest ...
