1. What is a coronavirus?
Coronaviruses are a large family of viruses, which may cause illness in animals or humans. In humans, several coronaviruses are known to cause respiratory infections ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The most recently discovered coronavirus causes coronavirus disease COVID-19.
2. What is COVID-19?
COVID-19 is an infectious disease caused by the most recently discovered coronavirus. This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019.
3. What are the symptoms of COVID-19?
The most common symptoms of COVID-19 are fever, tiredness, and dry cough. Some patients may have aches and pains, nasal congestion, runny nose, sore throat or diarrhoea. These symptoms are usually mild and begin gradually. Some people become infected but don’t develop any symptoms and don't feel unwell. Most people (about 80%) recover from the disease without needing special treatment. Around 1 out of every 6 people who get COVID-19 becomes seriously ill and feel difficulty in breathing. Old people, and those with underlying medical problems like high blood pressure, heart problems or diabetes, are more likely to develop serious illness. People with fever, cough and difficulty in breathing should seek medical attention.
4. How does COVID-19 spread?
People can catch COVID-19 from others who have virus. The disease can spread from person to person through small droplets from the nose or mouth, which are spread when a person with COVID-19 coughs or exhales. These droplets land on objects and surfaces around the person. Other people then catch COVID-19 by touching these objects or surfaces, then touching their eyes, nose or mouth. People can also catch COVID-19 if they breathe in droplets from a person with COVID-19 who coughs or exhales droplets.
5. Can the virus that causes COVID-19 be transmitted through the air?
Studies suggest that the virus that causes COVID-19 is mainly transmitted through contact with respiratory droplets rather than through air.
6. Can COVID-19 be caught from a person who has no symptoms?
The main way the disease spreads is through respiratory droplets expelled by someone who is coughing. The risk of catching COVID-19 from someone with no symptoms at all is very low. However, many people with COVID-19 experience only mild symptoms. This is particularly true at the early stages of the disease. It is therefore possible to catch COVID-19 from someone who has, for example, just a mild cough and does not feel ill.
7. protective measures for everyone
* Regularly and thoroughly clean your hands with an alcohol-based hand rub or wash them with soap and water.
* Maintain at least 1 metre (3 feet) distance between yourself and anyone who is coughing or sneezing.
* Make sure you, and the people around you, follow good respiratory hygiene. This means covering your mouth and nose with your bent elbow or tissue when you cough or sneeze. Then dispose of the used tissue immediately.
* Stay home if you feel unwell. If you have a fever, cough and difficulty breathing, seek medical attention. Follow the directions of your local health authority.
