COVID-19 symptoms range from mild illness to pneumonia. Some people recover easily, others may get very sick very quickly. Symptoms include fever or acute respiratory illness (eg cough, sore throat and shortness of breath). People with severe illness may have difficulty breathing, which is a sign of pneumonia and requires immediate medical attention.
It can take up to 14 days for symptoms to show after a person has been infected.
So far, most people in Australia with COVID-19 have had recent international travel or contact with a person known to have the virus. At the moment it seems severity increases with age. People aged over 60, people with weakened immune systems, and people with underlying health conditions, like diabetes, lung disease, heart disease and kidney failure are at higher risk of severe illness.
