The cases in Chandigarh are at a spree, the World Health Organisation, WHO recently said that people who are in their 20s, 30s and 40s often tend to be asymptomatic and are hence the drivers of the disease.
Rajesh Kumar, former Head, Department of Community Medicine and School of Public Health, PGI, said, “The probability of passing the infection from asymptomatic patients is lower than that of symptomatic patients. However, asymptomatic patients are more in number and producing more cases of infections. For example, 90 asymptomatic patients with probability of 0.5 per cent may infect 45 more persons while 10 symptomatic patients with probability of 2 percent can infect 20.”
He added, “The transmission mode is obvious for symptomatic people i.e. coughing or sneezing. On the other hand, an asymptomatic patient can transmit the virus while singing or talking loudly. Therefore, the use of masks should be advocated strongly. This can prevent inadvertent spread by an asymptomatic person who is not aware of his/her positive status.”
A recent data shared by the UT Administration shows that a majority of the patients (2,319), who have opted home isolation, and 384 patients lodged at COVID care centres are either asymptomatic or have mild symptoms. A total of 117 patients, who are moderate to critical cases, are admitted to the dedicated COVID hospitals; the PGI and the Civil Hospital, Sector 48.
Rest 171 patients are admitted to the dedicated COVID health centres; the GMSH-16, the GMCH-32 and the civil hospitals in Sector 22 and 45 and Mani Majra.
