"Intensive care units are filling up to capacity in some places, particularly in Europe and North America," said the WHO chief in a press briefing on Monday.
"But we cannot give up. We must not give up. Leaders must balance the disruption to lives and livelihoods with the need to protect health workers and health systems as intensive care fills up," he stated.
According to him, when leaders act quickly and deliberately, the virus can be suppressed.
But, where there has been political division at the national level and blatant disrespect for science and health professionals, confusion has spread and cases and deaths have mounted.
"This is why I have said repeatedly: stop the politicisation of covid-19. A pandemic is not a political football. Wishful thinking or deliberate diversion will not prevent transmissions or save lives," he stated.
"What will save lives is science, solutions and solidarity," he stated.
