Psittacosis Pneumonia: Diagnosis, Treatment and Interhuman Transmission
1Shandong First Medical University & Shandong Academy of Medical Sciences, Taian, 271000, People's Republic of China.
Abstract:
Psittacosis pneumonia is a zoonosis caused by Chlamydia psittacosis infection, mainly resulting from contact with aerosols of birds or poultry's urine, feces, and excrement. The clinical manifestations range from general symptoms of infection to severe acute respiratory syndrome and systemic diseases, currently diagnosed using metagenomic next-generation sequencing (mNGS) to improve diagnostic accuracy. To date, most reports have only discussed human exposure to poultry disease. However, the latest studies have shown that human-to-human transmission of Chlamydia psittaci occurs not only between infected patients and their close contacts but also between secondary contacts. After looking back on relevant literature at home and abroad in the past ten years, this paper reviews the diagnosis, diagnosis and treatment, and progress in epidemiological research of Psittacosis pneumonia.
Insights
Psittacosis pneumonia, a zoonotic disease from Chlamydia psittaci, can spread between humans, not just from birds. This review covers its diagnosis, treatment, and epidemiology.
Area of Science:
- Infectious Diseases
- Zoonotic Infections
- Respiratory Medicine
Background:
- Psittacosis pneumonia is a zoonotic disease caused by Chlamydia psittaci.
- Transmission typically occurs through contact with infected avian aerosols (urine, feces).
- Clinical presentations vary from mild symptoms to severe acute respiratory distress syndrome.
Purpose of the Study:
- To review the diagnosis, treatment, and epidemiological research progress of Psittacosis pneumonia.
- To highlight recent findings on human-to-human transmission of Chlamydia psittaci.
- To consolidate knowledge from the past decade of relevant literature.
Main Methods:
- Comprehensive literature review of domestic and international studies published in the last ten years.
- Analysis of diagnostic methods, including metagenomic next-generation sequencing (mNGS).
- Examination of reported cases and transmission patterns.
Main Results:
- Metagenomic next-generation sequencing (mNGS) is improving diagnostic accuracy for Psittacosis pneumonia.
- Evidence indicates human-to-human transmission of Chlamydia psittaci, extending to secondary contacts.
- Previous reports predominantly focused on poultry-to-human transmission, underrepresenting human-to-human spread.
Conclusions:
- Psittacosis pneumonia diagnosis and treatment require updated approaches considering human-to-human transmission.
- Further research into the epidemiology and transmission dynamics of Chlamydia psittaci is crucial.
- Enhanced surveillance and awareness are needed to manage this evolving zoonotic threat.
