Answers
Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus. Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment.

The disease caused by the novel coronavirus first identified in Wuhan, China, has been named coronavirus disease 2019 (COVID-19) – ‘CO’ stands for corona, ‘VI’ for virus, and ‘D’ for disease.
Formerly, this disease was referred to as ‘2019 novel coronavirus’ or ‘2019-nCoV.’
The COVID-19 virus is a new virus linked to the same family of viruses as Severe Acute Respiratory Syndrome (SARS) and some types of the common cold.
How does the COVID-19 virus spread?
The virus is transmitted through direct contact with respiratory droplets of an infected person (generated through coughing and sneezing), and touching surfaces contaminated with the virus. The COVID-19 virus may survive on surfaces for several hours, but simple disinfectants can kill it.
What are the symptoms of coronavirus?
Symptoms can include fever, cough, and shortness of breath. In more severe cases, the infection can cause pneumonia or breathing difficulties. More rarely, the disease can be fatal.
These symptoms are similar to the flu (influenza) or the common cold, which are a lot more common than COVID-19. This is why testing is required to confirm if someone has COVID-19. It’s important to remember that key prevention measures are the same – frequent hand washing, and respiratory hygiene (cover your cough or sneeze with a flexed elbow or tissue, then throw away the tissue into a closed bin).
How can I avoid the risk of infection?
Here are four precautions you and your family can take to avoid infection:
icon 1
Wash your hands frequently using soap and water or an alcohol-based hand rub.
icon 2
Cover mouth and nose with flexed elbow or tissue when coughing or sneezing. Dispose of used tissue immediately.
icon 3
Avoid close contact with anyone who has cold or flu-like symptoms.
icon 4
Seek medical care early if you or your child has a fever, cough, or difficulty breathing.
Should I wear a mask?
The use of a mask is advised to protect others even if you have no symptoms.
After masks are worn, they must be used and disposed of properly to ensure their effectiveness and to avoid any increased risk of transmitting the virus.
The use of a mask alone is not enough to stop infections and must be combined with frequent hand washing with soap and maintaining a physical distance.
Does COVID-19 affect children?
COVID-19 is a new virus, and we are still learning about how it affects children and pregnant women. We know people of any age can be infected and transmit the virus. However, older people and/or those with pre-existing medical conditions seem more likely to develop severe illness. Cold, mild cough, fever, and body pain are the common symptoms of infection. We have also noted that other symptoms such as pain in the abdomen, loose motions, and vomiting are also present in children.
Clinical features or symptoms affecting children and adolescents, possibly associated with COVID-19, can include but are not limited to: fever, headache, body pain, tiredness, cough, breathlessness, poor feeding, loss of taste or smell (in a child more than eight years old), rash, red or pink eyes, swollen and/or red lips, tongue, hands, feet, gastrointestinal problems (diarrhoea, vomiting).
