What You Need to Know About the Coronavirus

When there’s an outbreak of disease, public health professionals serve as indispensable conduits of truth. Separating fact from fiction about the 2019 novel coronavirus (COVID-19), first detected in Wuhan, China, in December 2019, is the most recent and urgent challenge for those safeguarding public health.

Providing an accurate flow of information can be especially difficult with a rapidly spreading infection like the new coronavirus, which the Centers for Disease Control and Prevention (CDC) calls “an emerging, rapidly evolving situation.”1

When it began issuing daily status reports on January 21, 2020, the World Health Organization (WHO) documented 282 confirmed cases of the new coronavirus.2 Two weeks later, the total number of cases climbed to 17,391,3 and has been rising since.

“WHO is working closely with global experts, governments, and partners to rapidly expand scientific knowledge on this new virus, to track the spread and virulence of the virus, and to provide advice to countries and individuals on measures to protect health and prevent the spread of this outbreak,”4 the organization reports on its website.

WHO offers a variety of resources to stakeholders that range from governments to community health workers. In this excerpted Q&A, WHO shares vital information about what it calls a “public health emergency of international concern.”5 Here are some of the important facts you should know about the coronavirus:6

What is a coronavirus?

Coronaviruses are a large family of viruses found in both animals and humans. Some infect people and are known to cause illness ranging from the common cold to more severe diseases such as Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS).

What is a “novel” coronavirus?

A novel coronavirus (CoV) is a new strain of coronavirus that has not been previously identified in humans. The new, or “novel,” coronavirus [COVID-19] … had not previously been detected before the outbreak was reported in Wuhan, China, in December 2019.

Who can catch this virus?

People living or traveling in an area where the virus is circulating may be at risk of infection. … [The virus] is circulating in China, where the vast majority of people infected have been reported. Those infected from other countries are among people who have recently traveled from China or who have been living or working closely with those travelers. … Health workers caring for persons who are sick with the virus are at higher risk and must protect themselves with appropriate infection prevention and control procedures.

How does the virus spread?

The new coronavirus is a respiratory virus which spreads primarily through contact with an infected person through respiratory droplets generated when a person, for example, coughs or sneezes, or through droplets of saliva or discharge from the nose. It is important that everyone practice good respiratory hygiene. For example, sneeze or cough into a flexed elbow, or use a tissue and discard it immediately into a closed bin. It is also very important for people to wash their hands regularly with either alcohol-based hand rub or soap and water.

How dangerous is it?

As with other respiratory illnesses, infection with the virus can cause mild symptoms including a runny nose, sore throat, cough, and fever. It can be more severe for some persons and can lead to pneumonia or breathing difficulties. More rarely, the disease can be fatal. Older people and people with pre-existing medical conditions (such as diabetes and heart disease) appear to be more vulnerable to becoming severely ill with the virus.

What can I do to protect myself?

Wash your hands frequently with soap and water or use an alcohol-based hand rub if your hands are not visibly dirty. … Maintain at least 3 feet distance between yourself and other people, particularly those who are coughing, sneezing, and have a fever. Avoid touching eyes, nose, and mouth. If you have fever, cough, and difficulty breathing, seek medical care early.

Should I wear a mask to protect myself?

Wearing a medical mask can help limit the spread of some respiratory disease. However, using a mask alone is not guaranteed to stop infections and should be combined with other prevention measures. …

WHO advises on rational use of medical masks thus avoiding the unnecessary waste of precious resources and potential misuse of masks This means using masks only if you have respiratory symptoms (coughing or sneezing), have suspected virus infection with mild symptoms, or are caring for someone with suspected virus infection.

What is the correct way to wear and dispose of a mask?

Before putting on a mask, wash your hands with alcohol-based hand rub or soap and water. Cover your mouth and nose with the mask and make sure there are no gaps between your face and the mask. Avoid touching the mask while using it; if you do, clean your hands with alcohol-based hand rub or soap and water. Replace the mask with a new one as soon as it is damp and do not reuse single-use masks. To remove the mask, remove it from behind (do not touch the front of mask) and discard immediately in a closed bin. Wash hands with alcohol-based hand rub or soap and water.

Are there any specific medicines to prevent or treat the virus?

To date, there is no specific medicine recommended to prevent or treat the novel coronavirus. However, those infected with the virus should receive appropriate care to relieve and treat symptoms, and those with severe illness should receive optimized supportive care. Some specific treatments are under investigation and will be tested through clinical trials. WHO is helping to coordinate efforts to develop medicines to treat the virus with a range of partners.

If you want to protect yourself from getting infected with the new coronavirus, you should maintain basic hand and respiratory hygiene, safe food practices, and avoid close contact, when possible, with anyone showing symptoms of respiratory illness such as coughing and sneezing. The following measures are not specifically recommended as COVID-19 remedies as they are not effective to protect yourself and can be even harmful:

  • Taking vitamin C
  • Smoking
  • Drinking herbal teas
  • Wearing multiple masks to maximize protection
  • Taking self-medication such as antibiotics
