Milder cases drive spread of coronavirus, finds study
Why is it in news?
- 86% of people in China who were infected with novel coronavirus (SARS-CoV-2) were not tested in the two-week period before travel restrictions came into force on January 23 in Wuhan and other cities.
- These undetected cases contributed to the majority of virus spread in the community, says a paper published in the journal Science .

- Findings of the study
(1) The researchers used a computer model that draws on observations of reported infection and spread within China in conjunction with mobility data from January 10-23 and January 24-February 8.
(2) People who experienced mild, limited or no symptoms were not detected but spread the virus anyway.
(3) The modelling study suggests that a “radical increase” in identifying and isolating people who have not been tested yet would be needed to fully control the spread of the virus.
