Mainland China posted dwindling new infections Wednesday in a global coronavirus pandemic and began to publish the daily change in cases which might be free of symptoms. However, the latter could complicate the picture of traits in the disease.
Virtually all of Tuesday’s 36 new cases involved arrivals from abroad, the National Health Commission stated, down from 48 a day before, and taking the count of infections to 81,554.
However, that figure excludes 130 new sufferers of the extremely contagious disease who don’t show symptoms, statistics from the well-being authority showed.
Some other nations include cases that test positive for the virus; however, they show no symptoms in the tally of confirmed cases, in line with advice from WHO.
China should “build a stable line of defense against the risks of an overseas epidemic”, and allow no loopholes, President Xi Jinping mentioned in a comment published Wednesday.
In his remarks throughout a visit to the eastern province of Zhejiang, Xi urged higher management of symptom-free cases.
Users of Chinese social media have expressed fear that carriers with no signs could be spreading the virus unknowingly, especially as authorities ease curbs on travel for hotspots in the epidemic, now that infections have subsided.
Last week, WHO epidemiologist Maria van Kerkhove told a conference in Geneva that symptomatic sufferers had been the principal drivers of transmission within the majority of circumstances, whereas most of these labeled as asymptomatic developed signs a few days after diagnosis.
