Abstract:
Prior to COVID-19, dengue was an important public health problem in Malaysia. Due to the movement control order
imposed by the Malaysian government to curb the COVID-19 transmission, a study predicted that mosquito-borne
diseases would increase during lockdown and partial lockdown seasons. Thus, this study aims to determine the current
situation of dengue incidence during the pre-COVID-19 pandemic (2019) and during the COVID-19 pandemic (2020
and 2021). We compared the number of laboratory-confirmed cases in the pre-COVID19 year (2019) and during the
COVID-19 pandemic (2020 and 2021). In addition to that, we characterized the clinical manifestation, dengue serotype
and viremia levels of dengue patients that were admitted to the Hospital Cancelor Tuanku Muhriz. We found a significant
decrease in the number of laboratory-confirmed cases between COVID-19 pandemic and the pre-covid period
(p2020=0.064; p2021<0.001). In this study, we found DENV 4 serotype was the most common serotype in dengue
patients admitted to our hospital. There was no significant correlation between DENV serotype/viremia level with
clinical manifestation of dengue fever and dengue with warning signs. However, patients infected with DENV4 had the
highest viral load compared to patients infected with other serotypes. We also found high viremia levels were significantly
associated with the febrile phase.
