Dengue has become endemic in India with outbreaks occurring almost every year. The seroprevalence and serotypic data of the last 7 years in samples obtained from suspected dengue patients from a tertiary care hospital were analyzed. Out of 7846 serum samples received in the virology laboratory from suspected dengue cases during 2002 to 2008, 2366 (30.15%) were serologically confi rmed. Serotyping was done using mRT-PCR. All the four serotypes were detected in 2003, while data in 2004, 2005 and 2006 revealed the the predominance of Den-3.
