Facebook CEO Mark Zuckerberg says the social network is stepping up its efforts to combat novel coronavirus-related misinformation by giving the World Health Organization (WHO) free advertising.

Zuckerberg said in a post on his Facebook account that the company is working with national health ministries and global organizations like the WHO, the US Centers for Disease Control and Prevention and UNICEF to get out timely and accurate information on the virus.

Zuckerberg said Facebook will also give “support and millions more in ad credits” to other unspecified organizations.

Facebook has previously taken other measures to fight virus hoaxes and misinformation, including removing false claims and conspiracy theories and showing users a pop-up directing them to the WHO or their local health authority for the latest information.

A Beijing-based intensive care doctor now working in Wuhan – the city at the epicenter of China's coronavirus outbreak – says designated hospitals in the city are seeing an increasing number of empty beds after a large number of virus patients were discharged.

COVID-19 Vaccine

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.

Du Bin added, however, that there's always the possibility of another spike in new cases.

Du on March 4 said that a major cause of deaths in younger patients may have been the prolonged application of certain high-dosage treatments that ended up causing more harm than good.

Cao Bin, a doctor specializing in respiratory research who is also currently in Wuhan, told reporters, “The war is not over.” Cao said Chinese researchers have led initial clinical trials of two antiviral drugs and will soon share the results of the trials with the World Health Organization.

Germany has joined several other countries in banning the export of medical equipment such as respiratory masks, gloves and protective suits in most cases. Germany, like other nations, has faced a shortage of such equipment as concerns over the widening coronavirus outbreak have mounted. In Germany itself, 240 infections have been confirmed so far.

Germany's interior ministry said Wednesday that exemptions from the export ban will be allowed only under strict conditions, such as for “concerted international aid actions.” Russia's government on Wednesday banned the export of masks, respirators and other protective gear along with anti-virus medicines until June 1. It also noted that the ban doesn't cover humanitarian aid.

The Ministry for Industry and Trade said the move is intended to prevent an “artificial deficit” of protective goods, which are being increasingly sold abroad as global demand has soared.

The Czech government also said it is banning exports of respirators and will start regulating their sale at home, saying it needs them for health workers and others. The Czech Republic has five confirmed cases of the new virus.
