Introduction: Meningococcemia is an important deadly bacterial infection. This infection is reported from several developing countries worldwide. In Indochina, this disease still exists and is an important disease under surveillance. In Indochina, meteorological background, humid, and hot and the spreading of meningococcemia might be promoted. Materials and methods: In this study, the authors report on a study on correlation between rainfall and the prevalence of meningococcemia in Thailand. Results and conclusions: From analysis on primary data, the least square equation interrelating between prevalence of meningococcemia (Y) versus rainfall (X) is “Y = “1.42 X – 8.37 (r = 0.48, p < 0.05).” Hence, impact of rainfall is possible. The present analysis can support the previous observations. However, the observed correlation coefficient is weak; hence, effect of other local factors is possible.
