Measles is a highly contagious viral infection that can cause serious complications. It spreads through the air when an infected person breathes, coughs or sneezes. Vaccination provides the best protection.
Symptoms
Early symptoms include a high temperature, cough, runny or blocked nose and red, sore, watery eyes. Small white spots may appear inside the mouth. A blotchy rash usually begins on the face and behind the ears before spreading down the body. The rash may be harder to see on brown or black skin.
What to Do If Measles Is Suspected
Contact a healthcare service urgently and call before attending a clinic. Measles spreads very easily, so staff may arrange an assessment that avoids exposing other patients. Prompt advice is especially important for babies, pregnant people, anyone with a weakened immune system and people who have not been fully vaccinated.
When to Get Emergency Help
Call your local emergency number for a seizure, severe breathing difficulty, inability to stay awake, sudden confusion, a stiff neck, pain from bright light, a child who is limp or not responding normally, or a rash that does not fade when pressed through a clear glass.
Care and Complications
There is no specific routine treatment for measles. Rest, fluids and appropriate medicine for discomfort may help. Follow professional advice about medicines for children. Complications can include pneumonia, seizures, inflammation around the brain and problems during pregnancy.
Preventing Spread
Follow local public health advice about isolation. Avoid close contact with babies, pregnant people and anyone with a weakened immune system. Wash hands, cover coughs and do not share cups, cutlery, towels or bedding. The MMR or MMRV vaccine protects against measles according to the vaccination program where you live.
