The Basic Reproduction Number for Dengue fever in Tamil Nadu (2012) Epidemic

Dengue is known in India since 1940s but the disease is very limited in its spread. Dengue is becoming rampant in many states of southern India. As of now no specific treatments or vaccines are available against the disease. The people of Tamil Nadu and Puducherry, where the dengue incidences are increasing, perceive this spurt as due to poor rainfall and power supply. A Case study, using data of the outbreak that occurred in 2012 in Tamil Nadu is presented [1]. There are different methods for calculation of basic reproductive number. The aim of this study is to evaluate the reproductive number using data from dengue cases in Tamil Nadu.
