Marriott Marquis flags measles exposure

San Diego County public health officials said on Saturday that workers and guests at the Marriott Marquis San Diego Marina may have been exposed to measles during a visit by an infectious person on May 17. The county said the potential exposure at the downtown hotel occurred between 9 a.m. and 3:45 p.m. at the property at 333 W. Harbor Drive, next to the San Diego Convention Center. Officials said they were working through the weekend to identify and notify people who may have been at risk. A second, unrelated measles case in the county did not result in public exposure, local reports said. ### Which hotel visit prompted the warning? The Marriott Marquis San Diego Marina was listed by county health officials as a public exposure site after an infectious person spent part of May 17 at the hotel. Fox 5 San Diego reported that the same person later visited a Baskin-Robbins in Imperial Beach on May 20 between 5 p.m. and 7:30 p.m. (sandiegouniontribune.com) The San Diego Union-Tribune reported that the county’s public notice sought to reach anyone who was at the hotel during the May 17 exposure window. The hotel is a large waterfront property near the convention center, according to Marriott’s website. ### What did officials say about the measles cases? (fox5sandiego.com) San Diego County confirmed two new, unrelated measles cases on May 24, according to 10News. One of those cases involved public exposure and led to the hotel advisory, while the second did not. Fox 5 San Diego said the infectious person tied to the public exposure did not have proof of measles vaccination. (sandiegouniontribune.com) County health officials have not, in the reports reviewed, identified the person publicly. ### What are people who were there supposed to do now? San Diego County’s measles guidance says vaccination is the best protection against the virus. (10news.com) The county says measles is highly contagious and that up to 9 out of 10 nearby unprotected people can become infected if exposed. The Union-Tribune and Fox 5 reported that health officials advised people who may have been exposed to check their vaccination records, watch for symptoms and contact a healthcare provider if symptoms develop. (fox5sandiego.com) Those symptoms can include fever and rash, according to county measles guidance. ### Why did the county issue a public notice instead of contacting people directly? (sandiegocounty.gov) San Diego County has used public exposure notices in earlier measles investigations when an infected person visited places where not everyone present could be identified. A county measles page from March shows officials publicly listed exposure times at Sharp Memorial Hospital while separately working with the facility to notify patients and employees who may have been exposed. (sandiegouniontribune.com) The current hotel advisory follows that same pattern. The Union-Tribune reported that county officials were using the notice to reach hotel workers and visitors who may not have been directly identifiable from records. ### Where can people look for updates? San Diego County maintains a measles information page and a year-specific case update page that it has used for prior exposure notices. (sandiegocounty.gov) The county also posts alerts for healthcare and public health professionals through its CAHAN San Diego system. As of May 24, the county had publicly linked the measles exposure warning to the Marriott Marquis San Diego Marina and the Imperial Beach ice cream shop visit. (sandiegouniontribune.com) Any additional exposure sites or case updates would be expected to appear through county public health channels and local media reports.
