INDIANAPOLIS -- There are no reported cases of swine flu in Indiana, but the state sent two specimens to the Centers for Disease Control and Prevention for testing.

Test results are expected to be in later this week. In the meantime, state health officials are asking Hoosiers to be aware of the threat and educate themselves about how to protect their families.

Several state and local agencies are monitoring the outbreak of swine flu in the U.S. and are sharing information with federal agencies, 6News' Julie Pursley reported.

Officials said being proactive and prepared will help reduce the impact of what could become a public health crisis.

"The good news is the current cases that we're seeing in the United States are mild," said Indiana Health Commissioner Dr. Judy Monroe. "However, that could change, because we know that influenza viruses can change rapidly."

Health officials urged schools and businesses to review contingency plans for coping with influenza.

Morgan said Indiana is prepared for a possible pandemic and has more than 651,000 doses of anti-viral medicines on hand, aside from stock at pharmacies and hospitals.

Indiana Travelers Reconsider Trips To Mexico

George Mikalaus left Indianapolis International Airport bound for Mexico Monday morning armed with hand sanitizer and disinfecting wipes.

Mikalaus said he isn't concerned about contracting swine flu, which is suspected in more than 100 deaths in that country, but wants to take precautions.

"I just really heard about this Saturday … but no, I'm staying with my plans," Mikalaus said.

Suzanne DeCellis, of AAA, said she has been told Mexico City is the only area of concern. Several airlines are now waiving change fees for travelers who had been scheduled to travel to that city.

"If … you were traveling to Mexico City within this time period, you should definitely think about changing your reservations," DeCellis said.

Most travelers bound for Mexico from Indiana are headed to tourist spots, such as Cancun, Cozumel, Puerto Vallarta and Cabo San Lucas.

"We have not had any reports, so for now, they need to wait and watch because those are areas where you cannot change your reservations right now," DeCellis said.

U.S. Customs and Border Patrol agents at the airport said they are keeping an eye out for anyone who appears to be ill.

"Anyone we see that looks like they may have the flu or show symptoms of the disease, we'll naturally interview them," said agent William Bell.

Anyone who has a trip scheduled to Mexico City and would like to change their plan should contact the airline directly.
