The surge is infecting people in cities ranging from Shenzhen to Qingdao on the coast, to Xingtai in the north and the numbers have crept steadily higher since early March. While the mainland's numbers are small relative to numbers reported in Europe or in the U.S., or even the city of Hong Kong, which had reported 32,000 cases on March 13, they are the highest since the first big outbreak of COVID-19 in the central city of Wuhan in early 2020.

Shanghai reported a record number of symptomatic COVID-19 cases on Saturday and other areas across China imposed restrictions as the country kept up its "dynamic clearance" approach that aims to stamp out the highly transmissible Omicron COVID-19 variant.

The Zhengzhou Airport Economic Zone, a central Chinese manufacturing area that includes Apple Inc supplier Foxconn, announced a 14-day lockdown on Friday "to be adjusted according to the epidemic situation".

In northwestern China, the city of Xian on Friday urged residents to avoid unncessary trips outside their residential compounds and encouraged companies to have employees work from home or live at their workplace, following dozens of COVID-19 infections this month.

A Xian government official, responding to residents' concerns over potential food shortages, said on Saturday that the announcement did not constitute a lockdown and that the city would not impose one.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
