Wuhan ramps up Covid-19 testing as fears of a second wave mount


The city at the epicentre of the original outbreak is facing the threat of a second wave of infections.

Wuhan, China – Authorities in Wuhan have

tested over 3 million residents for the coronavirus in April and

May and aim to test all of the rest, state media said, as the

city at the epicentre of the original outbreak faces the threat

of a second wave of infections.

Priority will go to residents who have not been tested

before, and people living in residential compounds with previous

cases of infection, or old or densely populated estates, the

official Xinhua News Agency reported late Thursday, citing a

Wuhan government meeting.

Fears of a second wave just as businesses and schools reopen

flared at the weekend after Wuhan reported a cluster of cases,

the first since a lockdown was lifted on April 8.

Those infections were previously asymptomatic – people who

had the virus but had shown no fever or other symptoms.

Authorities should have a clear indication of the number of

asymptomatic cases once everyone in the city has been tested,

Xinhua said, without giving a timeframe for that process.

Reuters, citing an internal document to district officials,

reported on May 11 that the city planned to conduct the tests

for the rest of its 11 million residents over just 10 days.

On Friday in open-air plazas, Wuhan residents waited

patiently in long queues for their turn to take the test.

“I think it’s necessary,” said Wuhan resident Tong Zheguang,

32. “There’s a possibility of a recurrence of the epidemic.”

Jiang Liandi, 70, said: “Of course I’m a little bit worried.

I’m also afraid there will be new infections.”

Wuhan has detected more than a dozen asymptomatic infections

per day in recent days.

Some experts say the mass testing is unprecedented in scale,

and shows the level of concern. Others say the sheer size of the

operation is bound to lead to errors.

The city conducted 1.79 million coronavirus tests from April

1 to May 13, according to Reuters calculations based on daily

reports published by the city’s health commission.

If Xinhua’s report that 3 million tests have been conducted

since April also uses figures from the health commission, that

would suggest up to 1.2 million tests were administered on May

14 alone.

But the health authority said late on Friday, without

elaborating, that 72 791 tests had been conducted on May 14.

That was up from 67 026 tests on May 13 and the

second-highest total since it started publishing such data on

Feb. 21.

Preventing a rebound

Recent outbreaks in the northeasterly Heilongjiang province

and Jilin city have contributed to fears of other fresh

outbreaks in China.

On Friday, the mainland reported four new confirmed cases

for May 14, the National Health Commission (NHC) said in a

statement on Friday. All were locally transmitted.

“The epidemic situation is now fragmented domestically, but

the task of preventing a rebound of the epidemic remains

arduous,” Zeng Yixin, a vice minister at the NHC, told a news


“The epidemic situation abroad is still severe and complex,

and the pressure to defend against the outside continues to

increase,” Zeng added, referring to cases of citizens returning

from abroad infected with the virus.

China has stopped foreigners entering as a precaution

against imported infections.

Zeng also said some Covid-19 vaccines were set to complete

their second-phase clinical trials in July.

Confirmed cases in mainland China stand at 82 933 and the

death toll at 4633. China does not include people who have been

tested and found to be asymptomatic carriers in its tally, and

does not publish a cumulative number of asymptomatic cases.
