A team from China describes dengue virus (DENV) genomic epidemiological features found in the country's Guangdong province for a paper in PLOS Neglected Tropical Diseases. The researchers did whole-genome sequencing on 114 DENV isolates from serotypes 1-4, which were collected in 21 cities between 2013 and 2017, using the sequence data to search for informative variants and signs of recombination, and to untangle phylogenetic relationships between the isolates.
