NEWBERRY, S.C. (WIS) - Officials at the Department of Health and Environmental Control say they have confirmed two "probable" cases of swine flu in Newberry and another two cases still uncertain.

DHEC released a statement to make the announcement:

"Of the viruses sampled, two were type A, unsubtypable. That means, because this is a novel virus, we will assume that these two cases that were tested at the lab do have the new swine flu virus and these will now be considered ‘probable cases,' so they are being sent to the federal Centers for Disease Control and Prevention for further evaluation and testing," said Jerry Gibson, M.D., chief of DHEC's Bureau of Disease Control.

"We can go on the working assumption that we've got two cases of the novel, so-called swine flu virus," said Dr. Gibson in a press conference.

Newberry Academy Headmaster Robert Dawkins says DHEC is visiting the home of the girl who tested probable to get more information. He adds that parents of students at the school are being asked to get Tamiflu, an antiviral medication, for their kids.

The school is expected to be sanitized on Tuesday to avoid further spreading of the virus.

The story began when thirteen Newberry Academy students and three adults went on a trip to Cancun, Mexico and returned with flu-like symptoms last Monday.

The virus has killed more than 100 people in Mexico and infected dozens in the U.S.

Newberry Academy has been closed since Monday as a precaution.
