Background: Dengue is one of the most predominant vector-borne infections worldwide, caused by an arbo-virus and transmitted by Ades aegypti mosquito. About half of the world's population is now at risk with around 100-400 million dengue cases occurring each year.[1] Dengue causes significant morbidity and mortality in many tropical countries including India.
Objective: To determine the morbidity profile and seasonal trend of dengue.
Methodology: A hospital based descriptive observational study was conducted during January to December’2019 (over 1 year) in an apex infectious disease hospital of Kolkata, West Bengal. Total 1340 admitted dengue patients were studied through interview technique and review of relevant reports.
Results: Out of total 1340 dengue patients majority were in the age group of 21-30 years (30.9%), male (56.1%), belonged to urban area (59.3%). Cases were showing inclining trend from the month of August, peaked at October-November, thereafter declined in December. Among the dengue cases 89.5% were classified as DF, 8.6% DHF and 1.9% DSS; case fatality rate was 0.45%. Overall 25.9% patients developed hypotension, 3.9% had hemorrhagic skin rash and 6.6% presented with other hemorrhagic manifestations.
Conclusion: In order to reduce dengue morbidity and mortality timely effective management and severity assessment by clinician is indispensible along with area specific awareness generation activity to be initiated during pre-monsoon period for vector control and personal protection by involvement of local leaders.
