Director-General of the World Health Organization (WHO), Tedros Adhanom Ghebreyesus, who already warned that most countries are still in the early stages of dealing with the coronavirus pandemic, has now announced that nost of the world's population is still susceptible to Covid-19 as only a low percentage of the population has antibodies to the virus.

Early serological studies reflect that a relatively low percentage of the population has antibodies to Covid-19, which means most of the population is still susceptible to the virus, WHO Director-General Tedros Adhanom Ghebreyesus said at a press briefing. He also discussed the steps taken by the countries to test, trace and isolate Covid-19 cases to prevent the virus from spreading further. "Countries put these stringent measures in place, sometimes called lockdowns, in response to intense transmission. Many have used the time to ramp up their ability to test, trace, isolate and care for patients, which is the best way to track the virus, slow the spread and take pressure off the health systems. The good news is that there has been a great deal of success in slowing the virus and ultimately saving lives. To protect lives and livelihoods, a slow, steady, lifting of lockdowns is key to both stimulating economies, while also keeping a vigilant eye on the virus so that control measures can be quickly implemented if an upswing in cases is identified," he reportedly further added.

Covid-19 has claimed the lives of more than 293700 people and infected over 4366600 people across the world. The virus was first identified in Wuhan, Hubei Province, in China. As the death toll and overall cases began rising rapidly across the world, the World Health Organization (WHO) declared a global health emergency and the outbreak has now been labelled a pandemic. A total of 8718 cases have been registered in Tamil Nadu so far, while 75066 cases have been confirmed across India. Tamil Nadu has reported 61 deaths while 2442 people have succumbed to the illness across the country.
