Asymptomatic coronavirus cases may be far more common than we thought.
A survey conducted by the U.K.'s Office for National Statistics revealed 86.1 percent of people who contracted COVID-19 between April and June showed no major symptoms of the disease, including cough, fever, or a loss of taste or smell, on the day they were tested. Around three quarters of those tested showed no symptoms at all, including fatigue or a shortness of breath, raising fears of a "silent transmission" by asymptomatic people, The Guardian reports.
