Effects of climate change on the distribution of influenza virus in Indonesia in 2012-2013
Influenza is a disease that occurs throughout the year in Indonesia. Surveillance of ILI (Influenza-Like Illness) has been ongoing since 2006, but information on the effect of climate change on the distribution of influenza virus in Indonesia is still limited. This study aims to determine the distribution pattern of influenza due to climate change in Indonesia in 2012-2013.
This study used ILI surveillance data for year2012-2013. All sentinel ILI divided by rainfall zones (region A, B or C). ILI case data were analyzed based on the distribution of positive cases of influenza per month in each region.
The positive case of influenza in 2012 was 858 (22.4%) and 624 (23.3%) in 2013. The case of influenza in Indonesia in 2012-2013 fluctuated each month following the rain patterns.
Conclusions: The pattern of distribution of ILI cases are different for each region according to the rainfall pattern in the area. (Health Science Indones 2014;2:78-82)
