High contagiousness of Delta variant combined with the peak tourist season leads to new cases in several provinces.
Provinces across China have imposed tougher restrictions in an effort to racing to contain the country’s worst coronavirus outbreak in months, with health officials attributing the surge in COVID-19 infections to the highly contagious Delta variant.
Authorities reported 328 symptomatic infections in July – almost equal to the total number of local cases from February to June.
“The main strain circulating at present is the Delta variant … which poses an even greater challenge to virus prevention and control work,” Mi Feng, spokesman for the National Health Commission (NHC), said at a news briefing on Saturday.
It came a day after the World Health Organization (WHO) urged governments globally to contain Delta before it turns into something deadlier and draws out the pandemic.
The WHO said an 80 percent average increase in COVID-19 cases was recorded over the past four weeks in five of the health agency’s six regions, a jump largely fuelled by the fast-spreading Delta variant.
First detected in India, the strain has now reached 132 countries and territories.
“Delta is a warning: it’s a warning that the virus is evolving but it is also a call to action that we need to move now before more dangerous variants emerge,” the WHO’s emergencies director Michael Ryan told a news conference.
According to a leaked document by the Centers for Disease Control and Prevention in the United States, a review of findings from other countries showed that while the original SARS-CoV-2 was as contagious as the common cold, each person with Delta infects on average eight others, making it as transmissible as chickenpox but still less than measles.
Nanjing cluster
In China, the current outbreak is geographically the largest to hit the country in several months, challenging its early success in curbing the pandemic within its borders.
More than 260 infections nationwide have been linked to a cluster in Nanjing city in eastern Jiangsu province, where nine cabin cleaners at an international airport tested positive on July 20.
Hundreds of thousands have already been locked down in the province, while Nanjing has tested all 9.2 million residents twice.
he contagiousness of the Delta variant, combined with the peak tourist season and high passenger circulation at the airport, has led to the rapid spread of this outbreak, NHC official He Qinghua told reporters at the briefing.
Fresh cases reported on Saturday in two more regions – Fujian province and the sprawling megacity of Chongqing – included one patient who visited the tourist city of Xi’an, in Shaanxi province, and an international cargo crew member who recently travelled from abroad, authorities said.
