Infections

An infection happens when an organism enters your body and causes disease.

Infections are caused by a virus, bacteria or fungi and can be picked up in lots of ways, either from an infected person, contaminated water, or even an insect bite – and new causes of infection like COVID-19 are always emerging.

Viral infections are among the most contagious, and include the flu (influenza) and the common cold. Healthy preschool aged children are most at risk and may have up to 12 colds per year.

If you have symptoms of an infection, a doctor can assess whether you need antibiotics or other treatment.
