Changing Pattern of Dengue Virus Serotypes in Thailand between 2004 and 2010
Dengue virus infection is a major concern in several countries, and
more than 50 million people are infected worldwide each year. Thailand
is one of the countries where people are susceptible to infection due
to favourable geographical and environmental conditions. In this
retrospective study, we reported the changing pattern of dengue virus
serotypes during the period between 2004 and 2010. The following
percentage prevalence showed different serotypes of dengue virus (DENV)
predominant in respective years: DENV1 in 2004 (56.41%), DENV4 in 2007
(50%), DENV1 in 2008 (57.41%), and DENV3 in 2010 (38.7%). Moreover, the
major serotypes were not stable as they showed a shift from one
serotype to another. We also found co-infection with two different
serotypes and reported the clinical manifestations, which were not
different from infection with a single serotype. Co-infection with
various serotypes may not necessarily cause more severe disease
