A new study has confirmed that people with kovid-19 positive will be highly contagious within the first five days of developing symptoms, emphasizing the need for rapid isolation.
According to research published in the Lancet, asymptomatic people can remove the virus from the body faster and be contagious in less time.
In the first systematic review of this type, researchers analyzed data from previous 98 studies on the transmission of coronavirus infection.
The researchers compared their findings on covid-19 with two other coronavirus strains to better understand why covid-19 spread so quickly. They found that SARS-CoV-2 (the virus that causes cobid-19) carries viral loads (the number of viruses detected in the body) in the upper respiratory tract at the onset of the disease, beginning on the fifth day of symptoms.
This is important because the upper respiratory tract virus is considered the main source of transmission. For comparison, the peak load of two other coronavirus strains (SARS-CoV and MERS-CoV) is at a peak later – 10 to 14 days and 7 to 10 days, respectively – to detect symptoms and provide more time in quarantine, HuffPost reported.
