Perfectly healthy-looking individuals (asymptomatic) around us from any age group are proven to be spreading more coronavirus than the sick individuals who show clear signs and symptoms of coronavirus illness that includes coughing, sneezing, runny nose, fever, etc.
On Tuesday, Dr. Sandra Ciesek, director of the Institute of Medical Virology in Frankfurt, Germany, tested 24 passengers who had just flown in from Israel.
Seven of the 24 passengers tested positive for coronavirus. Four of those had no symptoms, and Ciesek was surprised to find that the viral load of the specimens from the asymptomatic patients was higher than the viral load of the specimens from the three patients who did have symptoms.
Viral load is a measure of the concentration of the virus in someone’s respiratory secretions. A higher load means that someone is more likely to spread the infection to other people.
