Measles Case Reported in San Francisco After International Travel
San Francisco health officials announced Wednesday that an infant who recently returned from overseas has tested positive for measles. The child, who is under 12 months old and unvaccinated, was confirmed to have the virus on Monday evening after exposure during travel.
The infant is currently recovering at home, and all household members are reported to have been vaccinated against measles. Health officials are reaching out to people who had close contact with the family to ensure everyone’s safety.
This is the first measles case in San Francisco since 2019, though officials did not disclose specific travel details or any information about the child. At present, the general public’s risk of exposure is deemed low, but those who may have been in contact could be contacted by health authorities for further information.
Measles is a highly infectious disease that spreads easily through the air when an infected person coughs, sneezes, or even talks. The virus can linger in indoor air for up to an hour. Symptoms typically begin with a fever, cough, runny nose, and pinkeye, followed by a rash appearing 2 to 4 days later. Serious complications can occur, including pneumonia and, in rare cases, a severe brain disease called subacute sclerosing panencephalitis (SSPE).
Health officials strongly recommend the measles, mumps, and rubella (MMR) vaccine, which is safe and highly effective—about 97% effective after two doses. Dr. Susan Philip, a health officer, stressed the importance of vaccination, stating, “Measles is one of the most contagious diseases in the world. If you and your family are traveling internationally, make sure everyone is up to date on the MMR vaccine and knows the symptoms of measles.”
The MMR vaccine is usually recommended for children between 12 and 15 months, with a second dose between ages 4 and 6. Infants aged 6 to 12 months who are traveling can receive an early dose.
Residents with questions about the MMR vaccine and immunization records are encouraged to contact their healthcare provider.
