RIO DE JANEIRO, BRAZIL - World Health Organization (W.H.O.) Director-General Tedros Adhanom has reported that the global number of covid-19 cases has decreased for the fourth straight week over the past seven days. According to him, this is a result of restrictions imposed by countries and the progress of vaccination. "It is not yet time to relax protective measures," he said over a press conference in Geneva, Switzerland.
The W.H.O. has further stated that studies conducted to date do not suggest a lower vaccine protection against severe cases of the new strains detected.
