A number of countries including China and Japan have confirmed cases of second time Corona Virus infection.
The Covid-19 (coronavirus) outbreak which started from China is now reported to have killed at least 3,000 people globally.
As of Monday, almost 90,000 confirmed cases with the numbers outside China growing faster than inside China.
As the disease pattern is still unknown, there is no explanation yet for second-time infection.
While the world health body is yet to admit that the disease should be declared as pandemic, the WHO chief on Thursday said the Covid-19 outbreak has reached a “decisive point” and has “pandemic potential”.
Tedros Ghebreyesus said no country should assume it won’t get case.
“This virus does not respect borders. It does not distinguish between races or ethnicities. It has no regard for a country’s GDP or level of development.
“It is what is happening around the world that is now our greatest concern.We are at a decisive point,” he said.
He advised countries with new and lesser cases to act aggressively so that they can contain the virus.
