In April, the Hawaii Department of Health reported two measles cases on Oahu in a household member of an unvaccinated child who contracted the virus while traveling internationally.  

The DOH said Wednesday that no additional measles cases followed and that they have concluded there was no community spread. The state agency previously conducted contact tracing efforts and said it identified all the people who were exposed in public settings except those at the Daniel K. Inouye International Airport.

However, the DOH said measles cases in the U.S. are on the rise, with more than 1,000 cases already reported across 30 states this year. The agency warned the risk for more travel-related measles cases in Hawaii is still high, and said they recommend people work together to increase the MMR (measles, mumps and rubella) vaccination rate.

Measles is one of the world’s most contagious viruses. The virus spreads through direct contact with an infected person or through the air when an infected person coughs or sneezes. An infected person can spread measles up to four days after developing the rash and four days afterwards. The virus can remain in the air for up to two hours after an infected person has left the room.
