The World Health Organization, or WHO, warned on Monday that there might never be a “silver bullet” or an extraordinary solution like a perfect vaccine against COVID-19. WHO officials added that the road to normality would be long. And some countries would need to re-think how they deal with the health crisis. Johns Hopkins University estimates that, by August 3, more than 18 million people around the world had been infected with the disease and more than 690,000 had died. Also, some nations that thought they were over the worst of the crisis are experiencing a resurgence.
