Conclusion
In summary, COVID-19 should be considered as a differential diagnosis of
acute undifferentiated febrile illness. In endemic regions, however,
clinically suspected patients should be tested for both COVID-19 and
Dengue fever, especially during the rainy season. This will aid in
determining the burden of dengue and COVID-19 coinfection. Precise
diagnosis is very crucial considering clinical presentation, exposure
history and laboratory assays. During the COVID-19 pandemic, isolation
of febrile ill patients’ needs to be considered to, which leads to the
prevention of disease transmission. COVID-19 can show with nonspecific
symptoms; therefore, it is critical that physicians are aware of this
potential. As a result, instances of COVID-19 with extrapulmonary and
unusual manifestations, as well as co-infections such as dengue fever,
should not be overlooked when patients present to hospital settings,
where healthcare professionals should be cautious. We believe that a
combination of these strategies will help Bangladesh deal with the
COVID-19 and dengue virus outbreaks, lowering higher mortality rates and
increasing the survival rate of COVID-19 cases, which may be intensified
by dengue.
