The Delta variant of COVID-19, which shows signs of increased transmissibility, has been detected in over 80 countries and could quickly overwhelm health care systems, warns World Health Organization technical lead on covid-19 Dr. Maria Van Kerkhove. The WHO reports that new cases and virus deaths are rapidly climbing in Africa, and WHO regional director for Africa Dr. Matshidiso Moeti says the continent needs millions more vaccine doses to prevent new variants from emerging.
