Is measles caused by bacteria?

Because measles is viral, antibiotics do not remove the cause. The infection can produce fever, cough, runny nose, sore eyes, and a rash that spreads from the face downwards. Other illnesses can cause similar features, so symptoms alone cannot confirm measles. A [Fever](/symptoms/fever/) may be part of the illness without identifying its cause.

The virus can move between people through air and respiratory secretions, including in indoor settings. Review the [Measles](/conditions/measles/) information for the wider pattern and possible complications.

Phone a healthcare service before going to a waiting room, explain the symptoms and any exposure, and follow instructions about avoiding contact with others. Rest and fluids can support recovery. Do not start leftover antibiotics. Ask about [MMR Vaccination](/treatments/preventive-care-and-vaccination/mmr-vaccination/) if your record is uncertain; a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) can address diagnosis and prevention.

Seek urgent help for breathing problems, confusion, a seizure, severe dehydration, inability to wake normally, or a rapidly worsening condition. Contact a clinician promptly for suspected measles in a baby, during pregnancy, or with a weakened immune system. [Swollen Glands](/symptoms/swollen-glands/) may occur with infection but do not establish a measles diagnosis.

Ask whether an examination or test is needed, how to protect household contacts, how long to stay away from others, and whether vaccination advice is needed after exposure.
