Estimating the Incubation Period Distribution of Psittacosis: A Retrospective Observational Study.

ABSTRACT:

Background and aims

Human psittacosis is a zoonotic disease mainly transmitted by contact with birds. However, the recently identified potential human-to-human transmission indicated an emerging threat of this disease. This study aimed to estimate the incubation period of confirmed psittacosis cases.

Methods

We retrospectively collected epidemiological information on confirmed psittacosis cases in Hangzhou City, Zhejiang Province, China, during 2022-2024. Incubation period distributions were estimated from interval-censored exposure and illness onset data using Bayesian parametric models and the Turnbull nonparametric maximum likelihood method.

Results

The median incubation period of confirmed psittacosis cases was 11.3 (95% CrI: 8.5-14.2) days with a 95th percentile
