The occurrence and clinical characteristics of dengue, chikungunya, and Zika virus infections in a region of Dhaka City, Bangladesh

Background: Mosquitoes are the most important vector population in tropical and subtropical countries. It is extremely difficult to reduce the mosquito population in an overcrowded community. Recurrent rainfall also promotes their proliferation. As a result, mosquito-borne viral infections spread through the enormous population during the rainy season. This study sought to explore the current state of vector-borne viral infections in a specific area of Dhaka, Bangladesh. Methods: Blood samples were taken from symptomatic patients. Blood sera were tested using real-time RT-PCR. The detection kit is intended for the qualitative detection of Chikungunya, Dengue, and Zika viruses. Results: The findings revealed that the younger age group (21-30 years) had more Dengue cases, while the middle-aged group (41-50 years) had Chikungunya sickness. There were no cases of Zika among the 118 patients. All of the patients had fevers and headaches. Males had a 10% lower risk of Dengue virus infection than females. On the other hand, the male group was 50% more likely to have Chikungunya fever than the female group. A few patients tested positive for both Dengue and Chikungunya. Conclusion: Mosquitoes can transmit viral infections. Forest regions, pet waste, tyres, and lengthy wet seasons all contribute to mosquito proliferation. In this study, we investigated the current state of vector-borne diseases. Mosquitoes transmitted the Dengue and Chikungunya viruses across the population. Mosquito control is crucial because patients lack access to treatment. This project aims to raise stakeholders’ awareness of mosquito-borne diseases.
