Estimates are asymptomatic Corona Virus Cases are about 40-45% depending Anthony Fauci, With the World Health Organization Projection previously A similar estimate, although a new study suggests that silent diffusers could include more than three-quarters of cases.
Researchers from University College London have published their reviews by peers the findings Thursday in Clinical Epidemiology.
The study authors wrote: “Little is known about the proportion of infected persons who are asymptomatic and potentially“ silent ”carriers. They used data from an infection survey from the Office of National Statistics for Coronavirus (COVID-19), which surveyed households in England.
Of the 36,061 people who were tested between April 26 and June 27, 625 (1.7%) reported symptoms on the day of the test. Of the total, only 115 people tested positive, and of those, 76.5% reported no symptoms when tested, while 86% reported no symptoms of COVID-19.
The study focused on the “primary” symptoms such as coughing, fever, and loss of taste and smell.
The researchers said the results indicate that symptom-based testing will not fully capture silent or asymptomatic transmission, and “our analyzes indicate that asymptomatic cases of COVID-19 were widespread in the UK in the spring of 2020.”
They called for changing future testing strategies to prevent future outbreaks and recommended frequent and widespread testing regardless of symptoms. They said this could be possible by developing “simpler tests that produce rapid results at a low cost, and accept some loss of sensitivity.”
However, the Centers for Disease Control and Prevention (CDC) She recommends confirming the results It is rapid tests with a more sensitive test such as RT-PCR / Nasal Swab. The agency also advises that you self-quarantine for 14 days after exposure or travel, even if virus test results are negative.
