The County of Santa Barbara Health Department (County  Health) has a confirmed positive case of measles related to recent international travel of a county resident. The isolated case was confirmed Monday night and is the first confirmed case since 2019. County Health is actively investigating and coordinating with local healthcare providers and potential exposure to prevent further transmission.  

Measles is a highly contagious viral illness that spreads through the air when an infected person breathes, coughs, or sneezes. The virus can remain in the air for up to two hours after an infected person leaves a room. Those fully vaccinated have very low risk of  infection. People who are not fully vaccinated with two doses of the MMR vaccine, especially young children and pregnant people, are at the highest risk of infection.  

Who May Be at Risk

  • Anyone who is unvaccinated or has not completed the two-dose MMR (measles,  mumps, and rubella) vaccine series.  
  • Infants younger than 12 months, who are too young to be routinely vaccinated. 
  • Pregnant individuals who are not immune to measles.  
  • People with weakened immune systems, regardless of vaccination status. 

Measles Symptoms

A person with measles is contagious from 4 days before the rash appears and 4 days  after it disappears. Symptoms typically appear 7 to 14 days (up to 21 days) after exposure and include:

  • Initially cough, runny nose, and red/watery eyes (conjunctivitis)  
  • Rash typically appears 3-5 days after the first symptoms, starting on face, hairline and neck, spreading down to trunk, arms and legs  
  • High fever (may spike above 104 °F when the rash appears).

What To Do If You Were Exposed 

  • Check your vaccination records. Review vaccination records through your online Digital Vaccine Record to ensure you and your family are up to date on the measles, mumps, and rubella (MMR) vaccine. Two doses of MMR vaccine provide strong long-lasting protection against measles.  
  • Watch for symptoms. Monitor yourself for illness with fever and/or unexplained rash from 7 days to 21 days after an exposure.  
  • Notify a health care provider if you are at high risk. If you are pregnant, an infant under 12 months of age, you have a weakened immune system, and/or you are unvaccinated, contact and notify your health care provider for guidance and next steps as soon as possible if you believe you were exposed. 
  • If someone at home develops measles symptoms:  
    • Keep them isolated from other household members who are not sick, especially unvaccinated household members.  
    • Stay home and do not attend work, school, or public events.  
    • Call your health care provider immediately to let them know someone in your home may be sick with measles. Do not enter a healthcare facility before calling and notifying them of your measles exposure and symptoms.  

General Recommendations for the Public  

  • Make sure you and your family are up to date on the MMR vaccine. Two doses are 97% effective at preventing measles. Vaccination records can typically be found through your healthcare provider, your school immunization records, or the California Digital Vaccine Record (DVR). 
  • If you plan to travel, check your MMR vaccination status. Infants age 6-11 months traveling internationally may receive an early dose of MMR vaccine; talk with your pediatrician.
  • Schedule a vaccine appointment by contacting your local pharmacy or health care provider. MMR vaccines are covered for most people through health insurance plans, including Medi-Cal.  
  • Call ahead before visiting a medical office if you suspect measles, so the facility can prepare to prevent spreading the virus to others in the waiting area.
