4 February — What makes a person with COVID more contagious? Hint: not a cough
The amount of SARS-CoV-2 in a person’s body is a major factor in determining whether they are likely to transmit the virus to others, according to a study of nearly 300 infected people and their close contacts.
Most people with COVID-19 do not give it to anyone else, but some become ‘superspreaders’. To understand why, Michael Marks at the London School of Hygiene & Tropical Medicine and his colleagues monitored 282 people, deemed ‘index cases’, who had recently developed mild symptoms of COVID-19. The team also monitored 753 people who lived with, cared for or otherwise had close contact with the index cases (M. Marks et al. Lancet Infect. Dis.
doi.org/10.1016/S1473-3099(20)30985-3; 2021).
Only one-third of the index cases transmitted the virus to a close contact. Those with a relatively high ‘viral load’, a measure of the amount of virus in the body, were much more likely to pass on the virus than were those with a low viral load. Index cases were no more likely to transmit the virus if they had a cough than if they didn’t.
The findings suggest that tracing the contacts of people with high viral loads is especially important, the authors say.www.thelancet.com/journals/laninf/art...Ben mij er beetje aan het verdiepen in en hopelijk ontlokt het hier ook een discussie. Steeds meer en meer anti-PCR verhalen duiken er op maar tegelijkertijd is het wel de PCR die je (volgens mij) nodig hebt om saliva-samples te testen. LFT is daar niet goed genoeg voor.
