Also known as coronavirus, covid.

This page is general health information, not a diagnosis. Always consult a licensed clinician about your own health.

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

Mild cases are managed at home with rest, fluids and fever relief while limiting contact with others, especially the elderly. Doctors may recommend testing, and high-risk patients can benefit from early medical review. Vaccination reduces the chance of severe illness.

See a doctor urgently if

  • Difficulty breathing or chest pain
  • Oxygen-level concerns such as bluish lips or severe weakness
  • Fever lasting more than five days
  • Confusion or inability to stay awake
  • Symptoms in someone elderly, pregnant or with chronic illness
