Overview
COVID-19 is a respiratory infection caused by the SARS-CoV-2 virus, spread mainly through droplets when an infected person coughs, sneezes or talks. Most people now have a mild, flu-like illness, but older adults and people with conditions like diabetes or hypertension can still become seriously ill.
Symptoms
Fever or chills
Cough
Sore throat
Tiredness and body aches
Loss or change of smell or taste
Headache
Shortness of breath (more serious)
Causes & risk factors
Inhaling respiratory droplets from an infected person
Close contact in crowded, poorly ventilated spaces
Touching the face after contact with contaminated surfaces
Treatment & self-care
