Between 3/5/18 and 4/3/18, measles has been confirmed in six unvaccinated patients who are residents of Santa Clara County (5) and Alameda County (1). One additional linked case has been confirmed in Nevada. All cases are linked to an unvaccinated traveler who was exposed in Europe and developed measles after returning to the San Francisco Bay Area.
Measles is very infectious, and airborne transmission can occur in settings with large numbers of people like healthcare facilities, schools, child care facilities, shopping centers, public transportation, airports, and amusement parks. Marin County Public Health is advising physicians to be vigilant in identifying and appropriately managing suspected measles cases to avoid ongoing transmission and ensuring that their patients and staff are up-to-date with immunizations.
If you, a family member, or friend develop a rash with a fever ≥101°F (38.3°C) contact your health care provider immediately.
