Temperature and atmospheric pressure may be considered as predictors for the occurrence of bacillary dysentery in Guangzhou, Southern China.

INTRODUCTION

The control of bacillary dysentery (BD) remains a big challenge for China.

METHODS

Negative binomial multivariable regression was used to study relationships between meteorological variables and the occurrence of BD during the period of 2006-2012.

RESULTS

Each 1°C rise of temperature corresponded to an increase of 3.60% (95%CI, 3.03% to 4.18%) in the monthly number of BD cases, whereas a 1 hPa rise in atmospheric pressure corresponded to a decrease in the number of BD cases by 2.85% (95%CI = 3.34% to 2.37% decrease).

CONCLUSIONS

Temperature and atmospheric pressure may be considered as predictors for the occurrence of BD in Guangzhou.
