China Thursday reported small coronavirus outbreaks driven by the Delta variant in three provinces as a cluster linked to an eastern airport spreads despite mass testing and a vaccination drive.
The flareup, which began after nine workers at the Nanjing airport tested positive on July 20, has since seen 171 cases detected in Jiangsu province, while infections have spread to at least four other provinces.
It is geographically the largest spread for several months, challenging China’s aggressive containment efforts which have relied on mass testing, lockdowns and swift contact tracing.
The virus first emerged in the central city of Wuhan, but China has extolled its success in largely extinguishing the pandemic inside its borders, allowing the economy to rebound.
The new outbreak, coupled with cases seeping over the porous border with Myanmar, is threatening that record.
Officials in Jiangsu have locked down hundreds of thousands of residents, Lu Jing, a member of the epidemic prevention taskforce told reporters Thursday.
“Internet cafes, gyms, cinemas and karaoke bars and even libraries in Nanjing have been shut down,” he said.
The city has tested all 9.2 million residents twice as officials rush to curb the spread of the disease, he said adding the highly contagious Delta variant is posing challenges to containment efforts.
The southwestern province of Sichuan reported three new cases Thursday while Beijing reported one locally transmitted case, the first in six months.
The patient living on the outskirts of the Chinese capital had tested positive after returning from a theatre festival at a tourist hotspot in central China, health officials said.
