Coronavirus: Spain calls on army to fight Covid-19
Meanwhile, World Health Organization data said fatality and infection rates were easing in most regions.
Spain said Tuesday it will call in the army to try to help curb the spread of the coronavirus as parts of Europe and Asia battle new surges, while data from the UN health agency suggested the pace of transmission was easing in many parts of the world.
Governments have been ramping up efforts to contain the disease, which has claimed the lives of almost 814,000 people and infected at least 23 million since late last year.
World Health Organization data said fatality and infection rates were easing in most regions, notably in the hard-hit Americas, except Southeast Asia and the eastern Mediterranean.
In Africa, WHO regional director Matshidiso Moeti said new cases were declining after the continent passed "what seems to have been a peak".
But Health Minister Zweli Mkhize of hard-hit South Africa warned that "our biggest worry is whether in fact this is the first surge and there might be another one", pointing to the latest developments in Spain.
One of the worst-affected countries in Europe, Spain,†is to use 2,000 soldiers trained in tracking to help regions identify those who have been exposed to infected people.
"We can't let the pandemic once again take control of our lives... we must take control and halt this second curve," said Prime Minister Pedro Sanchez.
