Molecular characterization and phylogenetic analysis of Chikungunya virus from Delhi, India.

ABSTRACT:

Background

Chikungunya virus is an alpha virus with high similarity to Dengue and Zika viruses, both in transmission cycle and in clinical presentation. Chikungunya is a re-emerging mosquito-borne infection known to cause small to very large outbreaks/epidemics at frequent intervals. In 2016, India witnessed a large outbreak of Chikungunya infection affecting more than 58,000 people. This study was undertaken to look at the genotypic phylogeny to know the relatedness with previously reported strains.

Methods

During the 2016 outbreak, samples from all patients clinically suspected to have Chikungunya were collected and subjected to testing for IgM antibody by ELISA and viral RNA detection by RT-PCR. Sequencing of the E1 gene segment was done to create a phylogenetic tree comp
