The US Centers for Disease Control and Prevention (CDC) has reported more than 1,200 confirmed cases of measles in 2019, the most in any year since 1992. Measles was declared eliminated in 2000; however, the US is now on the verge of losing that designation. Measles Local Health Departments
Local health departments are on the front lines investigating possible measles cases and responding to outbreaks when they occur, and the large urban health departments that make up the membership of the Big Cities Health Coalition are no different. New York City, where there have been over 600 cases of measles, reports the department has deployed 400 staff during their response, with the local cost reaching more than $2 million. This is not unique to New York. Outbreaks result not only in severe illness, but also place significant pressure on already stretched financial and human resources in public health departments, and tight local budgets often have to find dollars to support this important on the ground work. Measles Local Health Departments
The current outbreak has largely been linked back to a handful of travelers who were exposed to measles abroad prior to coming back to the US. Such exposures can lead to outbreaks if and when those who are ill – or don’t yet know they are ill – come in contact with pockets of unvaccinated people in a community. Measles is a highly contagious disease, and the majority of this year’s cases have occurred in people who were not vaccinated. In some communities, the spread of false information about vaccines has impacted overall immunization rates, contributing to the severity of some of the localized outbreaks.
Los Angeles County
In April 2019, Los Angeles County Department of Public Health (LACDPH) responded to five local cases associated with an outbreak – all were unvaccinated and could be traced to an index case infected during international travel. For all suspected and confirmed cases, regardless of jurisdiction, public health officials interview each case to establish where they were and with whom they had been in contact, determining who else might be at risk for contracting the illness, and then follow up with those people, the case contacts. For example, during this outbreak, one of the confirmed cases went to the UCLA campus for multiple days attending classes, and another visited Cal State University Library, leading to over 1,800 known contacts from just two measles cases.

LACDPH worked with health services from both universities to assess the risk for the 1,800 contacts – important and valuable support – but the department also had to track down hundreds of people who were in public spaces visited by the confirmed cases when they were infectious. This included restaurants, ride shares, health care workers, and friends and family. Many members of the public self-identified as being in contact and made themselves known to officials, another great help to health officials.
To prevent further spread of measles, quarantine orders were issued to university contacts (nearly 350 people) and all those who had visited Cal State’s Library (more than 700 people who could be identified) while determining whether or not they at risk for developing measles. This was a labor intensive process, taking approximately 4,500 staff hours and costing between $1,000 – $2,000 to investigate each person that was a contact. With nearly 3,000 contacts identified, the health department invested between $3 and $6 million, in addition to the unknown costs of lost wages due to quarantine and university staff costs.
LACDPH communicated with diverse audiences to ensure the local community had accurate, clear information on the outbreak, so people could understand if they were at risk and what to do if they were exposed. Telebriefings were organized and health notices put up in key locations, such as the airport. Health information was translated into 11 foreign languages and the department worked with trusted local partners such as churches or community centers to help spread the word about measles.
Seattle & King County
A measles outbreak was also reported in Seattle & King County in April. One infected traveler passing through Sea-Tac airport resulted in nine cases over a two-month period, leading to at least 37 locations being identified by Public Health – Seattle & King County as places where people may have been exposed. Measles Local Health Departments
Detailed investigations were undertaken to reconstruct the activities and locations of cases during the infectious period. Ninety potential cases were investigated, leading to six confirmed cases of measles, and 397 close contacts were identified for active monitoring. This entailed a health official contacting the person on a daily basis to see if they had started to develop symptoms. Extensive messaging and materials were produced for health care facilities, schools, and businesses to try to limit the spread of disease. This has cost Seattle & King County over $280,000 to date, in addition to the costs borne by local businesses, service providers and to those who developed measles. The outbreak also strained staff resources, with some staff unable to maintain their routine responsibilities.The experiences of @lapublichealth and @KCPubHealth demonstrate the local impact that even a handful of measles cases can have.

Washington state was home to a legislative response, with the state passing legislation to remove philosophical or personal objection exemption for the measles, mumps and rubella vaccine. Further, at the federal level, local Congresswoman Kim Shrier (WA-08) introduced the VACCINES Act (Vaccine Awareness Campaign to Champion Immunization Nationally and Enhance Safety) to fund research on vaccine hesitancy. Measles Local Health Departments
The federal government is a key partner to local and state officials in any response, policy and monetary resources are crucial components to combating these measles outbreaks. The US Congress each year appropriates dollars for the 317 immunization program, which provides funds health department infrastructure to provide vaccines for those most in need. The budget passed by the US House includes a $39 million increase for FY20 (which starts Oct 1) to ensure high vaccination coverage levels in response to the measles outbreak. Measles Local Health Departments
In recent weeks, a number of bills have been introduced in the Congress related to vaccines hesitancy and surveillance that would help move us more towards the prevention rather than response end of the spectrum. In addition to the VACCINES Act, the Lower Health Care Costs Act authorizes a national campaign to increase awareness of vaccines and combat misinformation, and the Vaccines and Promotions Act directs the Department of Health & Human Services to assess the impact of social media in accelerating or mitigating public health crises.
These bills propose meaningful activities, and should they be enacted, federal dollars will need to be appropriated to support them. The experiences of Los Angeles County and Seattle & King County demonstrate the local impact that even a handful of measles cases can have – we must support local health departments and ensure they have the funds and resources to stand ready for future outbreaks.
