VANCOUVER, Wash. (AP) – Health officials say the number of confirmed measles cases in Washington has grown to 34, with nine more suspect cases.
Clark County Public Health said on Sunday that most of the cases include children under 10 years of age.
Officials say 30 of the patients were not vaccinated against the highly contagious disease and in four cases it is not clear if the person was vaccinated. One person was hospitalized.
Measles is a highly contagious viral disease that is contacted when an infected person coughs or sneezes. It can be kept in the air for a maximum of two hours in an isolated space.
The full vaccine is 97% effective and provides immunity for life.
