- The country’s only new infections confirmed in the past two days have been imported from overseas, suggesting containment measures worked
- But there are still likely to be infected people with mild or no symptoms, and questions over how the data was compiled, experts say
“With many of these cases having mild to no symptoms, ensuring that the whole country remains prepared and is actively looking for new cases is essential,” he said. “While it is possible there are no new cases, it is also very possible that somewhere in the country there are mildly infected people.”
Missing mild cases, and those infected but showing no symptoms, are a “legitimate concern”, according to Xi Chen, an assistant professor at the Yale School of Public Health.
“Eighty per cent of cases have mild symptoms, so zero cases is a milestone, but not the end of the epidemic in China,” he said. Patients with mild symptoms or who are asymptomatic can still spread the disease to others, he added, and this needed to be monitored carefully in the coming weeks.
The extent to which asymptomatic carriers contribute to spreading the disease is yet to be understood by scientists.
In addition, Hubei province in mid-February changed how it classified its confirmed cases, which caused a surge in infection numbers. This decision, which allowed doctors to diagnose a person by a clinical examination, not only by a positive laboratory test, was later reversed, leaving confusion about the true extent of the disease.
China must focus on keeping out imported cases, expert says
Other commentators said it could not be ignored that political considerations may play a part as China looks to highlight its communist governance model and portray itself as a global leader in combating the disease.
“We are in the midst of the most intensive propaganda operation of the [Communist] Party state in living memory, in trying to project its success in dealing with the virus,” Steve Tsang, director of the University of London’s SOAS China Institute, said. “That narrative requires statistical backup.
Data can be trusted when it comes with transparency about how it was collected, so that it can be independently evaluated, Tsang said.
Nis Gruenberg, an analyst with Berlin-based independent think tank the Mercator Institute for China Studies, said that the numbers could be viewed as an “indicator” of a reduction of cases in China.

“Some [Western critics] have been saying China and its system are ill-equipped to handle this outbreak, and now the Chinese government is trying to invert that argument and say, ‘Look at you, you are not doing it well enough,’” Gruenberg said.
The message from the Chinese government that it has succeeded in containing the virus may “politicise” the figures and is a potential driver for under-reporting around the country, according to Gruenberg.
“If history is any guide in China then there is a massive history of under-reporting for various reasons, both within the system and internationally,” he said. “I’m sceptical that this is the true number, or that anyone really knows the true number.”
