Infection Control Society of Pakistan (ICSP) has claimed that Brazil, South Africa, and the UK strains of Coronavirus are responsible for a large part of the total COVID-19 cases in Karachi in the ongoing third wave of the viral infection.
ICSP’s claim is based on the analysis of 3,510 COVID-19 positive samples obtained between December 2020 and February 2021, showing that these three strains accounted for 54% of these cases.
