Symptomless cases make coronavirus control harder

“Researchers in Germany have found that people can be infected without appearing sick, after symptom-based screening missed two cases of coronavirus in a group evacuated from China to Germany.

Several tests, including a throat swab, later confirmed the two people had the virus, the infectious disease unit at University Hospital Frankfurt says.

“We discovered that shedding of potentially infectious virus may occur in persons who have no fever and no signs or only minor signs of infection,” the researchers say. “It is unclear whether persons who show no signs or symptoms of respiratory infection shed [the virus].” See article at Sci Dev Net Website
