The World Health Organization (WHO) official has stated that people with SARS Cov-2 may not be infectious if they are ‘Asymptomatic’, a significant new claim about the understanding of the (Covid-19) coronavirus disease that experts around the world said could be premature. The spread of the virus from people without symptoms is “rare” even with warnings from numerous experts worldwide that such transmission is more recurring and likely explains why the pandemic is so hard to contain.
Maria Van Kerkhove, WHO official epidemiologist said at a press briefing in Geneva, where officials from the global health agency said that new coronavirus cases had their biggest daily increase ever and countries, must continue with efforts to accommodate the virus. She said, adding that these asymptomatic cases were identified through contact tracing of known patients and the lack of onward transmission by asymptomatic individuals was based on data from countries carrying out detailed contact tracing.
However, more than 7 million people have been reported infected with the coronavirus globally and over 4, 00, 000 have died.
The co-head of the government’s virus taskforce told Reuters on Monday that at least half of Singapore’s newly discovered coronavirus cases show no symptoms and reinforcing the city state’s decision to ease lockdown restrictions very gradually.
Meanwhile, China announced results from its population-wide testing where they found 300 asymptomatic patients among the city’s 9.98 million residents. However, On Tuesday, A total of 1,174 close contacts of the 300 cases have also been tested negative for coronavirus.
Also besides, the experts have sought to ask the WHO to make a distinction between whether the lack of transmission was true only in asymptomatic cases-people with an infection that is so mild that they never have any symptoms as compared to pre-symptomatic cases where people go on to later develop symptoms.
Researchers from China’s Guangzhou studied 94 patients and estimated that 44% of secondary cases were infected during the index patient’s presymptomatic. At Last, “Disease control measures should be adjusted to account for probable substantial presymptomatic transmission.”
