What is parrot fever? A chef in Zhongshan suffers from fever due to long-term exposure to poultry

On September 19, the reporter learned that Zhongshan Boai Hospital recently received a patient with repeated fever for 3 days. After consultation by Xu Lei, deputy director of the Department of Respiratory Medicine of Pok Oi Hospital, and testing by joint medical technology, the diagnosis was psittacosis infectious disease.

It is understood that psittacosis is a zoonotic infectious disease that can be carried by birds, poultry and wild animals. Once the human respiratory tract comes into contact with the carrier pathogen, the risk of infection is greatly increased, and there is a relatively rare possibility of human-to-human infection. The prognosis for human infection with psittacosis is 1%, but it cannot be ignored.

The patient admitted to Zhongshan Boai Hospital is a chef. He is often exposed to poultry in his daily work. After admission, the patient had repeated fever, accompanied by severe headache, limb pain, fatigue and other symptoms. One week after admission, he was still accompanied by fever and physical discomfort.

After the diagnosis of psittacosis infectious disease, Zhongshan Boai Hospital immediately treated the patient for the cause. It is reported that the patient’s fever has now subsided and his condition has improved. After discharge, he was transferred to the outpatient clinic for drug rehabilitation treatment.

How much do you know about parrot fever

Q: What kind of infectious disease is psittacosis?

Answer: Psitatis fever is a zoonotic infectious disease, mainly caused by psilocybin psilocybin, which is intracellularly parasitized by orchid-negative bacteria. Birds, poultry and wild animals can be carried and infected. Human-to-animal infection can occur through respiratory inhalation or close contact. Human-to-human transmission is also possible, but relatively rare. Psitavirus can affect people of any age and gender, but incidence peaks in middle age, with an age range of 35-55 years. The pathogen has been found in many countries and regions around the world, and with the migration of animals and the increasing number of pet birds, the infection of psittacosis has also shown an upward trend year by year.

Q: What are the clinical manifestations of psittacosis?

Answer: The symptoms of human infection with psittacosis are mainly respiratory diseases, and the clinical manifestations may vary. psittacosis is highly pathogenic, and most infected people have flu-like symptoms such as chills, sore throat, and headache. and endanger life. Studies have shown that the average incubation period of psittacosis infection from asymptomatic to fulminant invasive disease is 5-14 days. Other symptoms include altered mental status, neck stiffness, photophobia, hepatosplenomegaly, and pharyngitis. The specific performance is as follows:

CNS involvement can manifest as meningitis, cerebral ataxia, cranial nerve palsy, rhabdomyositis, Guillain-Barre syndrome, and epilepsy.

Respiratory manifestations include pneumonia, acute respiratory distress syndrome, respiratory failure, and septic shock.

Involvement of the heart can manifest as myositis, parotitis, endocarditis, and aortitis.

renal and digestive manifestations include acute interstitial nephritis, acute renal failure, glomerulonephritis, hepatitis, pancreatitis, and acute abdomen.

The fluid system presents with diffuse intraductal coagulation (DIC), splenomegaly, and eosinophilic syndrome.

Rheumatological manifestations include reactive arthritis and polyarteritis.

Q: What is the prognosis for psittacosis?

A: The prognosis for psittacosis depends primarily on the severity of the patient, comorbidities, and the duration of treatment and supportive care. Despite antibiotic treatment, mortality is estimated at 1%.
