Seasonal variation of Pneumocystis jirovecii infection: analysis of underlying climatic factors

Pneumocystis jirovecii causes severe pneumonia (PCP) in immunocompromised patients. Seasonal changes of PCP incidence may be associated with climate changes. In this first study using multiple linear regression statistics to assess monthly climatic data and Pneumocystis, PCP incidence was positively correlated with mean temperature, but not with rainfall or wind strength.
