Dengue Fever And Climate: Analysis In Thiruvananthapuram
Thiruvananthapuram, the capital district of Kerala state, has witnessed an alarming rise in dengue fever cases since
2010. An approach to analyze spatial and temporal trends was not yet undertaken in the State. The objective of this study was
to geographically map the confirmed cases and to determine relation to climatic correlates. Epidemiological data and
meteorological data from January 2011 to June 2014 were obtained from Health Service Department and Indian
Meteorological Departments respectively. A total of 8279 cases were analyzed. The monthly dengue fever occurrence,
climatic variables such as humidity, temperature and rainfall showed seasonality. A temporal trend was found between the
occurrence of the cases and rainfall every year. The findings of this study showed that timely geospatial analysis of available
routine public health data could be useful in the prediction and control of potential outbreaks in the district.
