A cross-sectional study in India has shown an increased number of COVID-19 infections in those between the ages of 0-19 and in women, a higher mortality rate and more incidences of post-vaccination infections with the Delta variant.
World Health Organization's (WHO) COVID-19 Weekly Epidemiological Update, issued this week, cited this cross-sectional study. The study, which has not yet been peer-reviewed, focused on demographic characteristics, including severe illness and mortality rates.

Researchers conducted this study in India among COVID-19 cases caused by the B.1 variant (a non-Variant Of Concern) and the B.1.617.2 Delta variant (a Variant Of Concern).
"Using viral genomic sequences from 9,500 COVID-19 patients, the study found an increased number of infections among younger age groups (0-19 years) and women, a lower mean age for infection and symptomatic illness/hospitalisation, higher mortality and more frequent incidences of post-vaccination infections with Delta variant compared to the non-VOC (B.1) variant," the WHO update said.
