Measles Exposure

Is this your child's symptom?

  • Exposure (close contact) to person with confirmed measles.
  • Your child has no symptoms of measles (rash, cough or fever).

Measles Exposure (Close Contact): Definition

Being near an infected person puts you at risk for getting measles. Examples of close contact are:

  • Living in the same house. Household contacts have the highest risk of catching measles.
  • For young children, being in the same childcare room or carpool.
  • Sharing eating utensils or drinking glasses.
  • Face-to-face contact such as kissing or hugging.
  • Being coughed or sneezed on.
  • Having prolonged close conversation (within 6 feet) of an infected person.
  • Caution: measles is one of the most contagious of all viruses. Even casual contact in the same school can put unvaccinated children at risk for infection.

Measles Transmission: How it Spreads

  • Cause: measles is caused by the Measles virus.
  • Spread: measles is a very contagious virus. Reason: It is spread by tiny airborne particles that carry the virus and can float in the air. These can remain in a closed area for up to 2 hours after the person with measles has left.
  • Also, respiratory droplets from coughing or sneezing on other people can spread the virus. They can cause disease by getting in the eyes, nose or mouth.
  • Incubation period: 10 to 12 days to onset of respiratory symptoms. Another 2 to 4 days to onset of the measles rash. Average time from exposure to rash is 14 days (range: 7 to 21 days).
  • Contagious period: from 4 days before until 4 days after the start of the rash.
  • Attack rate: the chance of getting measles after exposure is over 90% in unvaccinated persons

Measles (MMR) Vaccine: Age When Normally Given (AAP)

  • All children need to get their measles vaccines.
  • Children normally get their first vaccine at age 12 months. This gives 95% protection.
  • Children normally get their second vaccine (booster) at age 4 years. This gives 99% protection.
  • Protection against measles infections is permanent and lifelong.

Measles Symptoms

  • Measles starts with red eyes, runny nose, cough and fever. Respiratory symptoms continue for 2 to 5 days before the onset of the measles rash.
  • Koplik spots are tiny white specks on the lining of the mouth (inner cheeks). They appear 1 to 2 days before the onset of the rash. These are only seen with measles but can be difficulty to see.
  • The measles rash starts on day 2 to 5 of the illness. It's a blotchy red rash that starts on the face. The rash spreads downward to involve the entire body over the next 3 days. The rash is deep red. The rash is usually gone by 7 days.

Care Advice for Measles Exposure

Treatment for Close Contacts Without Symptoms

What You Should Know About Measles Exposure:

  • Your child has been exposed to the measles virus.
  • What you need to do depends on if your child has had measles vaccines or infection before.
  • Keeping your child's vaccines up-to-date always gives your child the best protection.
  • In any case, try to avoid further exposure to people with measles.
  • Here is some care advice that should help.

If No Prior Measles Vaccines or Infection, You Need the Vaccine for Protection

  • Your child has a high risk of getting measles in the next 10 to 12 days.
  • For protection from this infection, your child needs a measles vaccine as soon as possible. Call for a vaccine appointment now.
  • The vaccine is 90% protective if given within 3 days of exposure.
  • After 3 days of exposure, the vaccine is not helpful in preventing the disease from this specific exposure.

If Had Only One Measles Vaccine, You Need a Booster Vaccine

  • One measles (MMR) vaccine gives 95% of children protection against measles.
  • If that is the case, get a MMR vaccine booster as soon as possible.
  • Call now for a vaccine appointment.

If Had Measles Vaccine Twice in the Past, You Should be Protected

  • Since your child's measles (MMR) vaccines are up-to-date, your child is 99% protected against getting measles.
  • That means they have less than a 1% chance of getting measles.
  • If that happens, the symptoms would be much milder than regular measles.
  • You do not need to see your doctor.

If Had Measles Infection in the Past, You Should be Protected

  • Since you are certain that your child has had measles before, that means they are immune to measles.
  • Protection is lifelong.
  • Children do not get measles a second time.
  • You do not need to see your doctor.

If You are Not Vaccinated, Isolation is Needed for Known Measles Exposures:

  • Measles is extremely contagious.
  • If your child is unvaccinated, Isolate your child at home until 21 days has passed since the exposure.
  • DO NOT allow any visitors.
  • DO NOT send your child to school, childcare, or other public places.
  • Avoid close contact with others (hugging, kissing).
  • If you go to an ER or other medical facility, stay in the car until medical staff brings you a mask and escorts you in.
  • Because measles is so contagious, someone from the public health department may also contact you.

Call Your Doctor If:

  • Fever occurs
  • Rash occurs
  • Other symptoms of measles occur (such as cough)
  • You think your child needs to be seen
  • You have other questions or concerns

There are cases of measles in NC, and we are aware of exposures in Chapel Hill, Durham, and Wake County. We can give the MMR dose early to families who want it. This applies to infants 6-12 months who have not gotten a dose yet or kids under 4-5 years who have not gotten their second MMR dose. At this time, the NC DHHS and health departments are not recommending this unless traveling or living in an area with sustained transmission. 2 doses of the MMR vaccine are highly effective (97%) at preventing measles infections. At CHCAC, children receive their first dose at 12 months of age and a second dose at 4 years of age, ensuring they are fully protected as soon as possible, in accordance with the most up-to-date AAP recommendations. Some infants aged 6 months to 11 months who travel internationally or in high-prevalence areas may need a dose to protect them; however, they still require the 1-year and 4-year-old doses as well. If you are ever concerned about a possible exposure to measles, please CALL before entering our office. DO NOT ENTER the office. NC DHHS keeps a list of areas with measles exposures here . This is a highly contagious illness, and special precautions must be taken to prevent spread. The virus can be present in the air for 2 hours after an infected person is in the room, and 90% of susceptible patients can be infected. As always, if you have questions, we are here to help make sense of it all!
