Why is it important?

In 2016, there was a sudden rise in dengue cases reported in Rawalpindi, and in 2017, an outbreak of dengue occurred for the first time in Peshawar. Additionally, in 2016, cases of an unidentified illness emerged, which were later identified as Chikungunya virus infections. Therefore, this study aimed to determine the serotypes of dengue virus and the co-infection of Chikungunya virus in Lahore, Rawalpindi, and Peshawar during the period of 2016-2018.


I appreciate the valuable contributions of all the co-authors of this article in collecting samples and data from different locations in Pakistan. Through this collaborative effort, we were able to unravel the mystery of co-circulation of Chikungunya virus and Dengue virus infections in Peshawar, Pakistan.
