For how many days, people infected with Covid-19 can potentially transmit the virus

People infected with coronavirus are more likely to transmit the virus in the first five days after the onset of symptoms, a new study suggests. The study's authors, published in the medical journal The Lancet Microbe, said Thursday that the findings underscored the need to identify coronavirus-infected people early and the importance of isolating cases.

Understanding when patients are most likely to transmit the virus has become a critical public health concern in order to more easily control the global spread of Covid-19. "This is the first review and the first systematic meta-analysis that has comprehensively reviewed and compared the viral load for three human coronaviruses. "The study suggests why SARS-CoV [which causes Covid-19 disease] spreads more efficiently than SARS-CoV and MERS-CoV and is more difficult to control," said lead author Dr. Muge Cevik from the University of St Andrews in Scotland.

"Our findings are consistent with contact tracking studies, which suggest that most viral transmissions occur many times and especially within the first five days after the onset of symptoms, indicating the importance of self-isolation immediately after symptoms," he added. .

The study analyzed three coronaviruses - SARS-CoV-2, MERS-CoV and SARS-CoV - and their viral loads. Of the three, Covid-19 is more likely to be more infectious in the first five days of symptoms. The researchers noted that their analysis took into account only patients who went to the hospital and did not include people with milder infection. However, Drs. Antonia Ho from MRC-University of Glasgow, said that people with milder symptoms can fight the virus much faster.

Studiuesit paralajmëruan gjithashtu se edhe personat asimptomatikë mund të jenë po kaq infektues, por për një periudhë më të shkurtër.

Dr. Cevi tha: “Disa studime kanë zbuluar se individët me infeksion asimptomatike mund ta luftojnë virusin më shpejt, duke sugjeruar që ata pa simptoma mund të jenë po aq infektues sa ata me simptoma në fillim të infeksionit, por për një periudhë të shkurtër kohore.”
