Suspected Measles: Care Instructions

Measles is a highly contagious disease caused by a virus. It's also called rubeola (say "roo-bee-OH-luh"). It can cause serious illness or death, especially in young children and people who have not been vaccinated.

Measles travels through the air when an infected person coughs, sneezes, or breathes. The virus can stay in a room for up to 2 hours after an infected person has left. A person with measles can spread it to others starting 4 days before a rash appears and for 4 days after. About 9 out of 10 people who are not immune may get measles if they’re exposed.

If you've been exposed to measles, you might not know yet if you have it. There are things you can do to avoid spreading it to others, just in case.

• Contact your doctor right away if you aren’t vaccinated. If you get a measles vaccine within 72 hours (3 days) of exposure, it may reduce the chance of illness. If you don’t know if you had the vaccine as a child, getting another dose now won’t harm you.
  • Some people who can't get the measles vaccine may get a medicine called immune globulin. It works best within 6 days of exposure. This may be an option for people who cannot get the vaccine, such as those who are pregnant, those with a weakened immune system, and babies under 6 months old.
• Call ahead if you need to see a doctor. You’ll get special instructions. They may include using a different entrance, putting on a mask right away, and going to a separate exam room.
• Isolate yourself from others in a separate room at home. If you’re exposed and not vaccinated, you may need to stay home and away from other people for 21 days after your last exposure. It may be up to 28 days after your last exposure if you received immune globulin.
• Take precautions when you have to leave your room:
  • Wear a mask.
  • Wash your hands.
  • Cover coughs and sneezes.
  • Avoid unnecessary contact with others.
• Avoid public places and stay away from people, especially those who aren't immune to measles. This includes infants and anyone who is pregnant or has a weakened immune system.
• If you live in a group home or a senior living facility:
  • Let the staff know so they can isolate you.
  • Limit your contact with other residents and follow the guidelines above.
  • Avoid shared spaces such as dining rooms, recreation areas, and lounges.
  • Avoid group activities until your doctor says it’s okay to return.

Contact your doctor now or seek immediate medical care if:

• You have a fever with a stiff neck or a severe headache, or light makes your eyes hurt.
• You feel very sleepy or confused.
• You are short of breath.
• You have a cough that is getting worse.

Be sure to say that you may have measles. Measles is very contagious. The doctor may keep you apart from other people in the office. You'll get instructions on what to do.

Watch closely for changes in your health, and be sure to contact your doctor if:

• You do not get better as expected.
