There is a 50/50 chance that you have coronavirus of these people, says CDC
If you got Covid-19, you could catch it from this group of people.
While some people who contract COVID-19 have a general idea of howwhere they have been infectedOutside, others wonder who they came into contact with that carrying coronavirus. As experts learn more about COVID-19 and how it is transmitted, they constantly update the guidelines on the disease. According to recent estimates of disease control and prevention centers (CDC), if you had it, there is a 50/50 chance that you got someone's coronavirusesBefore seeing symptoms.
According to the CDC, the symptoms usually appear2 to 14 days after exposure to the virusAlthough some people never expose symptoms. In the days preceding the appearance of the symptoms, the infected person is always contagious. The CDC estimates that50% of the transmissions come from pre-symptomatic people.
"The possibility ofPre-symptomatic transmission Increases the challenges of confinement measures, "the CDC states. The key to the attenuation of pre-symptomatic propagation is of oneself in quarantine for two weeks if you believe you have come into contact with a COVID-19 case, even if you do not exposesymptom. The CDC says that pre-symptomatic transmissions emphasize the importance of social distancing and other preventive measures.

A recent study published byActs of the National Academy of Sciences of the United States of America (PNAS) examined the impact of "silent transmissions" (defined asPre-symptomatic and asymptomatic step) in the controlCOVID-19 epidemics. The study revealed that due to the omnipulation of "silent transmissions", symptom-based isolation can not prevent the propagation of coronavirus. According to the NAPs, quarantining of these with symptoms "must be supplemented by rapid tracing of contacts and tests that identify asymptomatic and pre-committed cases, in order to lift current restrictions safely and minimize the risk. resurgence ".
Since 50% of the transmissions occur before people showSymptoms of the virusThe protocols must be put in place to take into account this important source of infections. And for information on asymptomatic propagation, seeThe number of coovidants without symptoms increases, says CDC.
