Human Psittacosis Cases and Environmental Surveillance in Lishui, China (2021-2024)

Xiuying Chen's research provides epidemiological and environmental data on 28 laboratory-confirmed human psittacosis cases in Lishui City, Zhejiang Province, China. The dataset spans from 2021 to 2024, integrating clinical records, contact investigations, and results from 142 environmental samples. It was published on the figshare platform in April 2026.

Use Cases

• Analyze risk factors like age, occupation, and poultry exposure against severe disease outcomes (64.3% severe) and mortality (3 deaths).
• Model diagnostic delay (median 12 days) using patient demographic and clinical presentation features.
• Correlate environmental sample positivity rates (14.79% overall, 26.7% in duck manure) with human case locations and timelines.
• Study transmission patterns using data on 205 close contacts and the detected household cluster of 3 cases.

Strengths

• Includes 28 laboratory-confirmed human cases with detailed epidemiological characteristics.
• Integrates multi-source data: clinical records, contact tracing for 205 individuals, and 142 environmental samples.
• Covers a defined 4-year time period from 2021 to 2024.

Limitations

• Small sample size of 28 confirmed cases limits statistical power for subgroup analyses.
• Geographic scope is limited to a single city (Lishui), reducing generalizability.
• Environmental detection of C. psittaci DNA does not confirm viability or transmissibility.
