Ckikungunya virus infection and relationship to rainfall, the relationship study from southern Thailand.

There are several important mosquito borne infectious disease in the tropical countries. Chikungunya virus infection is an important arbovirus in this group. We hereby used a standard medicogeographical analysis to assess the correlation between prevalence of Chikungunya virus infection and rainfall in the endemic area of Thailand, the Southern region. In this work, the correlation was poor but significant. The result is concordant with a similar report from the retrospective analysis from the local center of disease control. Several other factors can affect the pattern of Chikungunya virus infection in the studied endemic area.
