[Seasonality of XXXX in Venezuela: relationship between monthly rotavirus incidence and rainfall rates].

@entity6425 @entity281
In general, it has been reported that @entity6425 was detected year round in tropical countries. However, studies in Venezuela and Brazil suggest a seasonal behavior of the @entity281 . On the other hand, some studies link @entity281 with climatic variables such as rainfall. This study analyzes the pattern of behavior of the @entity6425 in Carabobo-Venezuela (2001-2005), associates the seasonality of the @entity281 with rainfall, and according to the seasonal pattern, estimates the age of greatest risk for @entity281 . The analysis of the rotavirus temporal series and accumulated precipitation was performed with the software SPSS. The @entity281 showed two periods: high incidence (November-April) and low incidence (May-October). Accumulated precipitation presents an opposite behavior. The highest frequency of events (73.8% 573/779) for those born in the period with a low incidence of the virus was recorded at an earlier age (mean age 6.5 +/- 2.0 months) when compared with those born in the station of high incidence (63.5% 568/870, mean age 11.7 +/- 2.2 months). Seasonality of the @entity281 and the inverse relationship between virus incidence and rainfall was demonstrated. In addition, it was found that the period of birth determines the age and risk of @entity281 . This information generated during the preaccine period will be helpful to measure the impact of the vaccine against the rotavirus.
