China on Sunday claimed 25 of the 30 news coronavirus cases it confirmed were imported.
China’s National Health Commission said the five locally transmitted cases were reported from the southeastern province of Guangdong.
In a statement, the commission said three deaths were reported on Saturday from Hubei province, the capital of which is Wuhan, initially at the center of the global coronavirus outbreak.
“Hubei reported no new cases of confirmed infections, no new cases of suspected infections, and 3 deaths.”
However The National Health Commission said in a statement on Monday that 78 new asymptomatic cases had been identified at of the end of the day on Sunday, compared with 47 the day before.
Imported cases and asymptomatic patients, who have the virus and can give it to others but show no symptoms, have become China’s chief concern in recent weeks after draconian containment measures succeeded in slashing the infection rate.
Of the new cases showing symptoms, 38 were people who had entered China from abroad, compared with 25 a day earlier. One new locally transmitted infection was reported, in the southern province of Guangdong, down from five a day earlier in the same province.
The new locally transmitted case, in the city of Shenzhen, was a person who had travelled from Hubei province, the original epicentre of the outbreak, Guangdong provincial authorities said.
The Guangdong health commission raised the risk level for a total of four districts in the cities of Guangzhou, Shenzhen and Jieyang from low to medium late on Sunday.
Mainland China has now reported a total of 81,708 cases, with 3,331 deaths.
Daily infections have fallen dramatically from the peak of the epidemic in February, when hundreds were reported daily, but new infections continue to appear daily.
The country has closed off its borders to foreigners as the virus spreads globally, though most imported cases involve Chinese nationals returning from overseas.
The central government also has pushed local authorities to identify and isolate the asymptomatic patients.
