Dengue is an important systemic viral infection that is caused by the dengue virus. Ribonucleic acid (RNA) from dengue NS1 positive samples, collected randomly during dengue epidemic from October 2016 to October 2017 at Chugtai Lab, was extracted for nucleic acid. Both the detection and serotyping of dengue samples were performed using real-time PCR on Rotor Gene Q. From the 70 NS1 positive samples, 57 (81.4%) samples were confirmed to be positive for dengue virus RNA, while the remaining 13 (18.6%) were negative. Serotype 1 (DEN-1) was verified among all samples by in-house assay and using commercial kit FTD (Fast Track Diagnostics) dengue differentiation; it was concluded that our in-house assay is in 100% concordance with commercial kit. Serotype 2 (DEN-2) and serotype 3 (DEN-3) have been documented in Pakistan since 1994. But recent detection of serotype 1 in Pakistan is indicative of more severe dengue haemorrhagic fever in future due to reinfection.
