Introduction:
Psittacosis is a well-recognized zoonotic infectious disorder caused by Chlamydia psittaci (C. psittaci). Human-to-human transmission of C. psittaci has rarely been reported previously, especially in the case of healthcare-associated infections.
Case Report:
A 32-year-old man was admitted to the intensive care unit with severe pneumonia. An intensive care unit healthcare worker contracted pneumonia 7 days after performing endotracheal intubation on the patient. The first patient, a duck feeder, had been closely exposed to ducks, while the second patient had not been exposed to any birds, mammals or poultry. C. psittaci sequences were obtained by metagenomic next-generation sequencing analyses of bronchial alveolar lavage fluid of both the patients, and they were diagnosed with psittacosis. Therefore, healthcare-associated human-to-human transmission between both cases took place.
Conclusions:
Our findings have implications for managing patients with suspected psittacosis. stringent protective measures are needed to prevent healthcare-associated human-to-human transmission of C. psittaci.
Insights
Healthcare workers should implement stringent protective measures, as this study documents rare human-to-human transmission of psittacosis (Chlamydia psittaci) in a hospital setting. This zoonotic infection can spread between patients and staff, highlighting the need for increased vigilance.
Area of Science:
- Infectious Diseases
- Zoonotic Infections
- Microbiology
Background:
- Psittacosis is a zoonotic disease caused by Chlamydia psittaci (C. psittaci).
- Human-to-human transmission of C. psittaci is rare, particularly in healthcare settings.
- This highlights a potential gap in understanding infection control for this pathogen.
