Doctors at a hospital in Wuhan, China, where the virus emerged reported that between 3 and 14% of cured patients became reinfected with the illness, though it’s unclear whether they were contagious the second time, the South China Morning Post reported.
The news comes as experts raised an alarm that China is facing a second outbreak due to the increasing number of imported cases as well as the ‘silent carriers’ who show no symptoms.
