Abstract
Background
India is one of the countries in the World Health Organization South-East Asia
Region that regularly reports outbreaks of dengue fever (DF)/dengue hemorrhagic
fever (DHF). As effective control and preventive programmes depend upon
improved surveillance data, this study was carried out to report the seroprevalence
of dengue virus infection in an area around Jamnagar city, Western India.
Methods
The laboratory records of clinically suspected dengue patients from July 2008
to June 2011 were analysed retrospectively for the results of immunoglobulin
M (IgM) anti-dengue antibodies, tested by dengue monoclonal antibody (IgM)
capture enzyme-linked immunosorbent assay (MAC ELISA). Variations in disease
incidence by sex, age group and season were assessed.
Results
A total of 903 serum samples were tested, of which 253 were positive. The majority
were males (72%) and in the age group of 16–30 years. The incidence of dengue
peaked in October and slowly tapered by December.
Conclusion
Dengue cases were higher during September to December, in the post-monsoon
season. This observation is useful for planning special preventive strategies. The
study draws attention to the susceptibility of the male, young adult age group.
