This factor contributes to increased transmission of the virus
Many of those infected, being asymptomatic, did not detect the virus
The COVID-19 it is a disease from which we still have a lot to learn, so researchers and scientists do not stop studying everything that helps them stop the transmission of a virus, SARS-CoV-2, which has rarely caused a pandemic before seen. An example is found in the results of a study by researchers from Cedars-Sinaipublished in JAMA Network Openin which it is pointed out that more than half of people infected with the Omicron variant did not know they were infected.
susan chengdirector of the Institute for Research on Healthy Aging in the Department of Cardiology at the Smidt Heart Institute at Cedars-Sinai and one of the study’s authors, puts it this bluntly: “more than one in two people who were infected with Omicron did not know they had it“In fact, it is a fact in line with other research that pointed out that between 25 and 80% of people infected with COVID-19 do not show visible symptoms. Of course, Ómicron is an even milder variant.
Sandy Y. Younganother of the authors of the research, adds that “the findings of our study add to the evidence that undiagnosed infections can increase transmission of the virus“. In summary, the fact that there are many asymptomatic people or whose disease has not been detected in time contributes to the incidence of COVID-19 is even higher.
