People who are positive for Kovid-19 are most contagious in the first five days after symptoms appear, confirms new research, emphasizing the need for rapid isolation.
Studies published in The Lancet also show that asymptomatic people can clear the virus from their bodies faster and remain contagious for less time. This was explained by Krutika Kupali, a scientist at the Stanford University School of Medicine in California.
According to previous studies, the percentage of asymptomatic cases can reach 80%, but the new analysis, which involved 21,708 patients, shows that asymptomatic cases are 17%, or drastically less!
In the first study of its kind, researchers analyzed data from 98 previous studies on the transmission of coronavirus infection. They compared their findings to two other types of coronavirus to better understand why Covid-19 is spreading so fast. The researchers found that the viral load, ie. the amount of virus detected in the body during the different stages of SARS-CoV-2 infection peaks in the upper respiratory tract at the onset of the disease, between the onset of symptoms and the fifth day. This is important because the virus in the upper respiratory tract is considered a major source of transmission, writes BGNES.
By comparison, the viral load for the other two types of coronavirus, SARS-CoV and MERS-CoV, peaked later, between 10 and 14 days and 7 and 10 days, respectively, providing more time to recognize symptoms. HuffPost reported.
