Georgia health officials said Friday that they are trying to contact some state residents who attended a church conference near Seattle where they may have been exposed to the measles.

No measles cases have been reported in Georgia, though the Centers for Disease Control and Prevention on Thursday warned of several outbreaks across the United States. Unvaccinated children and infections brought in from foreign countries are fueling the spread of the highly contagious disease, the agency said.

The Georgia Division of Public Health is trying to get contact information for residents who attended the Generation Church Conference in late March in Kirkland, Wash.

An unknown number of Georgia residents were among the 2,000 to 3,000 participants at the conference, said Donn Moyer, a spokesman at the Washington State Department of Health.

Seattle health officials are investigating eight suspected measles cases in one family. "It is possible that the first child was exposed while at the conference in late March, but we have not confirmed this connection," said Matias Valenzuela, spokesman for the Seattle and King County health department.

In addition to this cluster, the CDC said there have been 64 cases of measles reported nationwide from Jan. 1-April 25 — the highest number since 2001.

Measles, which can be a life-threatening illness, usually causes a rash, fever, and cough. Health officials are urging parents to ensure their children are properly vaccinated.

Georgia's health department is working to raise awareness among the state's doctors of the measles outbreaks and reminding them to immediately report rashes so they can be investigated, said spokeswoman Taka Wiley.

The state doesn't track how many Georgia children have not been vaccinated against measles. But a national CDC survey estimates the 2006-2007 measles vaccination rate for Georgia children 19 months to 35 months of age was 93 percent, compared with 92 percent nationwide, Wiley said.
