1. It is mentioned that the microbiology department is one of the sentinel surveillance center under NVBDCP. It included all samples received from OPD, IPD, and from multiple hospitals.

2. Based on our primary objective, we included only samples positive for dengue and excluded others. Our objective was not to assess co-infections with dengue.

3. We included only those cases who were diagnosed by IgM or NS1 Antigen test which are diagnostic tests and not the screening test. Thus, sensitivity and specificity was not mentioned.
