Coronavirus pandemic | New cases doubles to 99 in mainland China as imported infections hit a record high

In addition, highlighting another major source of risk, newly reported asymptomatic coronavirus cases nearly doubled to 63 on April 11, from 34 the previous day, according to China's National Health Commission (NHC).

Mainland China reported 99 new coronavirus infections on April 11, more than doubling from the previous day to reach a one-month high, as the number of single-day imported cases hit a record, official data released on Sunday showed.

In addition, highlighting another major source of risk, newly reported asymptomatic coronavirus cases nearly doubled to 63 on April 11, from 34 the previous day, according to China's National Health Commission (NHC).

Almost all the new infections - the biggest daily count since March 6 - involve travelers from overseas. Just two out of the 99 cases were locally transmitted.

Shanghai, China's commercial hub, contribute to more than half of the imported cases. The city reported 52 new coronavirus cases on April 11, all involving Chinese nationals traveling from overseas, the municipal health commission said on Sunday.

Of Shanghai's new cases, 51 flew in on the same flight from Russia on April 10. The 52nd case involves a Chinese national arriving in Shanghai from a trip to Canada.

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.
