Anxious WHO implores world to 'do it all' in long war on COVID-19

The World Health Organization warned on Monday that there might never be a "silver bullet" for COVID-19 in the form of a perfect vaccine and that the road to normality would be long, with some countries requiring a reset of strategy. WHO Director-General Tedros Adhanom Ghebreyesus and WHO emergencies head Mike Ryan exhorted nations to rigorously enforce health measures such as mask-wearing, social distancing, hand-washing and testing. The WHO head said that, while the coronavirus was the biggest health emergency since the early 20th century, the international scramble for a vaccine was also "unprecedented".
