Types of measles: what to know

Measles is also known as rubeola and is caused by a highly contagious virus. It is not divided into separate routine types in the way some conditions are. A typical illness may begin with fever, cough, runny nose and irritated eyes, followed by a spreading rash. Swollen glands can occur, and symptoms may be more severe in babies, adults, pregnant people or anyone with reduced immunity. Terms such as modified measles may describe a milder or altered presentation after partial immunity; they do not make the infection harmless or non-contagious.

Call a healthcare service before attending in person if you have fever and a new rash after a possible exposure. This allows infection-control advice and reduces contact with vulnerable people. A GP consultation can review symptoms, exposure and vaccination history. Rest, fluids and advice about fever may help, but antibiotics do not treat the measles virus. Check vaccination records with a clinician; MMR vaccination is the main preventive measure and may be advised for eligible people.

Seek urgent help for breathing difficulty, severe dehydration, unusual sleepiness, confusion, a seizure or a child who is difficult to wake. Contact a clinician promptly for suspected measles because complications can affect the lungs, ears or brain and the infection spreads readily.

Ask whether your symptoms fit measles, how to avoid exposing others, whether testing is needed, and whether your vaccination record calls for MMR protection.
