Measles affects Utah power plant

SALT LAKE CITY, June 21 (UPI) -- Workers at a Utah power plant who may have been exposed to measles have been asked to stay home unless they can show proof of vaccination, plant officials said.

Health officials say the disease appears to have spread to Millard County in west-central Utah from Cache County in the north, The Salt Lake Tribune reported Tuesday. The carrier appears to have been a Millard County resident who got married in Logan, the Cache County seat.

A spokesman for the Intermountain Power Agency plant in Delta says about 100 of the 500 employees are affected. All were born after 1957.

"From an operational standpoint, this fits in the inconvenience category," John Ward said. "People will have to shuffle schedules a bit, but we're still running."

The Utah Bureau of Epidemiology said the measles virus may have spread to Cache County from Salt Lake City.

Measles, a quickly spreading viral disease, was once common among children. The disease is now rare in the United States.
