If someone is infected with the Coronavirus, there will be symptoms within 1-14 days since exposure to the virus. Common symptoms are:
Most people will only experience mild symptoms, but in certain cases, infection can cause pneumonia and breathing difficulty. In a small number of cases, the Coronavirus infection can be fatal. Older people (elderly) and people with health problems such as high blood pressure, heart problems or diabetes may experience more serious illness.
As the symptoms are similar to the common cold, a test is needed to determine whether a person is infected with the Coronavirus. Tests are available at referral hospitals for people who experience symptoms with a doctor’s referral.
The keys to prevent the Coronavirus (COVID-19) are clean your hands with soap and running water as often as possible, avoid touching your face, stay away from people who show symptoms (fever, dry cough, fatigue), when coughing or sneezing: cover mouth and nose with elbows folded or tissue that is thrown immediately into a closed trash can.
