Dengue, an arboviral infection is a notifiable disease in India and is endemic in many regions of the country. CRP levels help in knowing the severity of the disease. Patients with signs and symptoms of Dengue were included in the study. Their demographic data was noted. Serum was tested for NS1 ELISA, IgM ELISA. Positive samples were tested for CRP levels. Platelet count, Blood transfusion information was noted. Dengue positivity was 21%, with male predominance (55.6%), common in young children and teens. CRP level of 12 mg/L was seen in 28.40% of patients. Patients with CRP of 48mg/L required multiple platelet transfusion. Conclusion: our study has correlated dengue positive patient’s platelets, CRP levels and need for blood transfusion. CRP levels help in knowing the severity of dengue disease.
