With SARS, those infected became seriously ill. Once they were quarantined from others, the virus stopped spreading. In contrast, China is still finding dozens of asymptomatic cases of the coronavirus every day despite bringing its epidemic under control. This is very likely to be an epidemic that co-exists with humans for a long time, becomes seasonal and is sustained within human bodies, said Jin Qi, director of the Institute of Pathogen Biology at Chinas top medial research institute, the Chinese Academy of Medical Sciences.
A consensus is forming among top researchers and governments worldwide that the virus is unlikely to be eradicated, despite costly lockdowns that have brought much of the global economy to a halt. Some public health experts are calling for the virus to be allowed to spread in a controlled way through younger populations like Indias, while countries like Sweden have opted out of strict lockdowns.
Anthony Fauci, the director of US National Institute of Allergy and Infectious Diseases, said last month that Covid-19, the disease caused by the virus, could become a seasonal ailment as evidenced by cases now showing up in countries across the southern hemisphere belatedly as they enter their winter seasons.
Over 3 million have been sickened and over 210,000 killed in the global pandemic.
While some including US President Donald Trump have expressed hope that the viruss spread will slow as the temperature in northern hemisphere countries rises in the summer, Chinese experts on Monday said that they found no evidence for this. The virus is heat sensitive, but thats when its exposed to 56 degrees Celsius for 30 minutes and the weather is never going to get that hot, said Wang Guiqiang, head of the infectious diseases department of Peking University First Hospital. So globally, even during the summer, the chance of cases going down significantly is small.
