This is how likely you are to have a silent case of Covid.
The research determined the probability of having an asymptomatic case of coronavirus.
TheCoronavirus is continually searchedEspecially when it comes to determining the amount of symptomatic people against asymptomatic. Various studies report different asymptomatic prevalence rates by 6% up to 96%. So, what is the truth? According to new research, the probability of having a silent case of Covid is actually at the lower part of the spectrum.
A recent study, published in thePlum medicine Journal on September 22, showed that asymptomatic cases actuallyrepresents only a minority of Covid infections. The researchers conducted a systematic review of 94 studies from March to June that had data on a few more than 600 coronavirus patients. Through their conclusions, they could estimate thatOnly 20% of coronavirus infections remain asymptomatic.
Of the 6,600 patients, nearly 1,300 years have never finished bySympathize. Since a person starts initially without symptoms, it means that about 80% of people are symptomatic after having tested positive for coronavirus.
"The conclusions of this alive systematic review suggest that most people infected with SARS-COV-2 will not remain asymptomatic throughout the infection," said the study.
According to researchers, these data are troublesome because most people arePositive test for coronavirus Even before their symptoms start. This can meanA lot of narrow contact implications go unnoticed before the start of the symptoms. After all, the researchers noted that the "secondary attack rate was lower in the contacts of people with asymptomatic infection than those with symptomatic infection".
"The contribution of pre-symptomatic and asymptomatic infections to the global transmission of SARS-COV-2 means thatPrevention measures of the combination, with improved hand hygiene and respiratory tract, tests and isolation strategies and social distancing,will continue to be necessary, "Diana Buitrago-Garcia, co-author for the study and researcher at the University of Bern, said in a declaration.

Researchers also noted that their systematic review can be better adapted to the availability of the exact rate of people with silent coronavirus cases since the research that only publishes people at a given time "will overestimate the proportion of the true asymptomatic infection , because those who will develop the symptoms of COVID-19 will be wrongly classified as asymptomatic rather than pre-symptomatic. "
For example, one ofAmerican studies they examined Calculated that 27 people who have tested positive for the coronavirus were asymptomatic. However, 24 of these people who end up developing symptomsafter Their test - which means they were actually pre-symptomatic non-asymptomatic.
"The conclusions of systematic examinations, including ours, do not support the affirmation that a vast majority of SARS-COV-2 infections are asymptomatic," said Berne researchers in their September study. And for more information on COVID cases,Half of COVID patients made this mistake, a new study says.
