Weather: driving force behind the transmission of severe acute respiratory syndrome in China?
BACKGROUND
The association between weather and severe acute respiratory syndrome (SARS) transmission in Beijing and Hong Kong in the 2003 epidemic was studied to examine the effect of weather on SARS transmission.


METHODS
Pearson's correlation analyses and negative binomial regression analyses were used to quantify the correlations between the daily newly reported number of SARS cases and weather variables, using daily disease notification data and meteorological data from the two locations.


RESULTS
The results indicate that there were inverse association between the number of daily cases and maximum and/or minimum temperatures whereas air pressure was found to be positively associated with SARS transmission.


CONCLUSIONS
The study suggests that weather might be a contributory factor in the 2003 SARS epidemic, in particular in the transmission among the community members.
