What is psittacosis?
A person can become infected with pathogens of psittacosis from any type of birds. Ornithosis (psittacosis) - severe infectious disease, which is caused by bacteria that resistant to disinfectants. Infection occurs through contact with parrots. The causative agent of the disease - chlamydia psittaci (from Lat. «psitta» - parrot). There are four species of ñhlamydia, three of which cause inflammation of the lung in humans. Transmission of the causative agent of psittacosis from person to person is registered extremely rare. But if this does happen, then the patient should be isolated. The incubation period lasts an average of 10-12 days. Psittacosis is similar to acute respiratory viral infection, typhoid fever, and pneumonia, and therefore identification is extremely hindered, so the diagnosis is often delayed. In severe cases, the disease in elderly or debilitated people can be fatal. Children and young people usually survive. Infection affects the entire body, so the fully recovery - only within a few weeks.

Causes of psittacosis
The disease is caused by chlamydia - bacteria, which parasites in birds. Once in the body, they multiply and infect tissues. Birds shed chlamydia in the faeces.

The chance of infection is increased in those bird owners who "kiss" with their pets, does not follow the rules of personal hygiene. Other carriers of infection - urban pigeons, those are accumulating in one place and contribute to its spread.

Course of the disease
Symptoms appear on 7-15 days after contact with infected birds. The disease develops gradually, at first, variations in temperature, headache and muscle pain, heart palpitations, cough, sometimes nosebleeds, diarrhea, excessive thirst are observed in the patient. After these symptoms resembling acute viral respiratory infection or flu, the most often - pneumonia develops, sometimes - jaundice or delirium. The fever lasts about three weeks, then it disappear along with other symptoms gradually. Chlamydia often spread through the bloodstream throughout the body. They are particularly quickly multiply in the liver and spleen, so this disease is characterized by an increase in these organs, and sometimes by heart disease.
