A person can be infected with COVID-19 for up to 14 days before showing any symptoms. While pre-symptom transmission of the virus is possible, medical experts currently think it is less common than post-symptom transmission. Symptoms of infection include runny nose, fever, cough and difficulty breathing.
COVID-19 is commonly spread through respiratory droplets when an infected person coughs or sneezes. Transmission can occur through close personal contact, or by touching something that has the virus on it and then touching your mouth, nose or eyes before washing your hands.
Scientists studying the virus have determined that it can remain detectable for up to three hours in the air, four hours on copper, a day on cardboard and 2-3 days on plastic and stainless steel.
If you have cold or flu-like symptoms you are asked to self-isolate to limit your contact with other people unless you have been directed to seek medical attention. To reduce the possibility of transmission, practice proper cough/sneeze etiquette by coughing/sneezing into your elbow. Practice social distancing, too, by keeping two metres between yourself and other people. And you should also wash your hands frequently (and thoroughly) with soap and water.
