A Platte County woman in her thirties who just came back from Mexico is exhibiting symptoms of Missouri's first possible case of swine flu. She has not been hospitalized.

The woman, whose name could not be released, lives in the northern part of the county and has no school-aged children.

Her test results have been sent to the Centers for Disease Control in Atlanta after determining she has a new virus similar to swine flu. 

Margaret Donnelly, director of the Department of Health, says a Missouri resident who was hospitalized in Nebraska could be counted as Missouri's second possible case of swine flu.

Donnelly says there have been no business closings in Missouri.

According to Donnelly, a couple dozen people have been tested in Missouri.

The test is a nasal swab that is sent to the state health lab.

Susan Hoskins, Emergency Response Manager at the Platte County Health Department, says there is no need for alarm.

Hoskins says Platte County has received their allotment of antiviral medicine from the state. Most other local public health agencies can expect their allotment today.

Antivirals are only distributed to people with symptoms. They are not vaccines and only treat the symptoms of the virus.
