In the current study, hepatomegaly was found in 26.5% (n = 287)
of patients – 43.7% of children and 19.9% of adults. Hepatomegaly
has been reported to be common in adults17 and absent in
children20 in previous studies; however hepatomegaly was absent
in both children and adults in one previous study.14 Inter-observer
variation might be one of the reasons for these discrepancies in the
clinical findings. Moreover, the immune status of the affected
population to dengue viruses and the genetic makeup of the
infecting dengue virus might also have had an influence on the
variation in clinical manifestations.
