COVID-19 – Everything you Need to Know

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.

 

What are the symptoms of COVID-19?

The most common symptoms of COVID-19 are:

  • Fever
  • Tiredness
  • Dry cough

Some patients may have:

  • aches and pains
  • nasal congestion
  • runny nose
  • sore throat or diarrhea.

These symptoms are usually mild and begin gradually. Some people become infected but don’t develop any symptoms and don’t feel unwell.

 

How does COVID-19 spread?

People can catch COVID-19 from others who have the 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. People can also catch COVID-19 if they breathe in droplets from a person with COVID-19 who coughs out or exhales droplets or by touching objects or surfaces with these droplets and then touching their eyes, nose or mouth. This is why it is important to stay more than 1 meter (3 feet) away from a person who is sick. 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.

 

What can I do to protect myself and prevent the spread of disease?

You can reduce your chances of being infected or spreading COVID-19 by taking some simple precautions:

  • Regularly and thoroughly clean your hands with an alcohol-based hand sanitizer or wash them with soap and water for 20 seconds.
  • Maintain at least 1 metre (3 feet) distance between yourself and anyone who is coughing or sneezing.
  • Avoid touching eyes, nose and mouth.
  • 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 and call in advance. Follow the directions of your local health authority.
  • Keep up to date on the latest COVID-19 hotspots (cities or local areas where COVID-19 is spreading widely). If possible, avoid traveling – especially if you are an older person or have diabetes, heart or lung disease.
  •  Self-isolate by staying at home if you begin to feel unwell, even with mild symptoms such as headache, low-grade fever (37.3 C or above) and a slight runny nose, until you recover. If it is essential for you to have someone bring you supplies or to go out, e.g. to buy food, then wear a mask to avoid infecting other people.
  • If you develop fever, cough and difficulty breathing, seek medical advice promptly as this may be due to a respiratory infection or other serious condition. Call in advance and tell your provider of any recent travel or contact with travelers.

 

How long is the incubation period for COVID-19?

The “incubation period” means the time between catching the virus and beginning to have symptoms of the disease. Most estimates of the incubation period for COVID-19 range from 1-14 days, most commonly around five days.

 

How long does the virus survive on surfaces?

It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems to behave like other coronaviruses. Studies suggest that coronaviruses (including preliminary information on the COVID-19 virus) may persist on surfaces for a few hours or up to several days. This may vary under different conditions (e.g. type of surface, temperature or humidity of the environment).

If you think a surface may be infected, clean it with simple disinfectant to kill the virus and protect yourself and others. Clean your hands with an alcohol-based hand sanitizer or wash them with soap and water. Avoid touching your eyes, mouth, or nose.
