Measles outbreak shows vaccination value Thu Oct 27, 3:24 PM ET



A large measles outbreak in Indiana earlier this year shows what can
happen when an imported case of measles encounters a group of
unvaccinated individuals.

This outbreak and the serious cases that arose would not have occurred
if long-standing measles vaccination guidelines had been followed,
researchers from the Centers for Disease Control and Prevention reported
Thursday in their Morbidity and Mortality Weekly Report.

The source of the Indiana outbreak, which occurred over a 4-week period
in May and June, was an unvaccinated female teenager who had visited
Romania at the time of a major measles outbreak.

Soon after she returned to Indiana, 34 measles cases occurred, most of
them involving children whose parents had declined to have them vaccinated.

All of the patients recovered, although three were hospitalized,
including one who required mechanical ventilation, the report indicates.

Local health departments in Indiana, Ohio, and Illinois took a number of
measures to prevent the outbreak from spreading further, including
voluntary patient isolation, giving vaccine and immunoglobulin to
susceptible contacts, and verifying the immune status of healthcare workers.

"The Indiana outbreak could have been prevented by adherence to
long-standing Advisory Committee on Immunization Practices
recommendations calling for measles vaccination of 1) international
travelers, 2) children, and 3) healthcare workers," the report emphasizes.
