Reported COVID-19 cases around the world surpassed 1 million on Thursday, doubling in a week as the virus spreads across Europe and North America and establishes a toehold in Africa. The spread of the deadly virus, since it first originated in China, has reached 205 countries now, it said.
It comes as the country's leading infectious disease expert says there is a "reasonably good chance" the USA will face a second wave of coronavirus later this year.
The number of confirmed U.S. cases has reached 189,510, the most in the world, though Italy and Spain have recorded more fatalities.
Italy recorded its highest number of fatalities with almost 14,000 and more than 110,500 cases, while Spain reported deaths exceeding 10,000 and diagnosed greater than 110,200 patients. In total, 47,189 people have died from Covid-19, while 193,989 have recovered from the disease. Washington state has confirmed 222 COVID-19-related deaths.
Many countries, including Canada, have imposed restrictions on travel and the ability of their citizens to move around in cities, including closing businesses and requiring that people only go out when essential - in some cases imposing fines.
The WHO has repeatedly emphasized the potentially devastating impact of epidemics across Africa, where many health systems are ill-equipped to care for what could be an overwhelming number of critical patients.
