Dr Tedros told a virtual briefing on Monday: “We all want this to be over. We all want to get on with our lives. But the hard reality is this is not even close to being over.
“Although many countries have made some progress, globally the pandemic is actually speeding up.”
“With 10 million cases now and half a million deaths, unless we address the problems we’ve already identified at WHO, the lack of national unity and lack of global solidarity and the divided world which is actually helping the virus to spread… the worst is yet to come,” he said.
“I’m sorry to say that, but with this kind of environment and conditions we fear the worst.”
He also urged more governments to follow the examples of Germany, South Korea and Japan, which kept their outbreak in check through policies that included rigorous testing and tracing.
What are the worst-affected countries?
The US has reported more than 2.5 million cases and about 126,000 deaths with Covid-19 so far – more than any other nation.
US states that emerged from lockdown in recent weeks – notably in the south – have been reporting sharp increases in new infections in recent weeks.
