Fair Oaks, CALIFORNIA (BNO NEWS) – Health officials are investigating a suspected swine flu case at a Fair Oaks elementary school in California, health officials told BNO News on Sunday evening.

“Essentially it’s a possible case, a teenage student at a Fair Oaks school,” Kerry Shearer said, who is a spokesman for the Sacramento County Division of Public Health. The teenager, who is a student at St. Mel’s School, had recently came in contact with several people who visited Mexico and became ill.

“The student was tested and it was of an influenza type that could not be sub typed,” Shearer said. The samples have now been sent to the CDC to confirm or rule out swine flu. The CDC is expected to receive the samples on Monday morning but it can take several days before the results are known.

Because of the suspected case, a county health officer recommended that the school should be closed until there are no new cases of respiratory illness. About 275 students attend the school and none of them have so far reported illness, the principal of the school has agreed with to close the school. Health officials will monitor the students for the next days.

Shearer said the school will likely not reopen before Thursday. He could not provide details on the teenager to protect his or her identity.

“The symptoms were mild and that’s what we’ve seen in the U.S. so far, just mild symptoms unlike in Mexico where it has been more serious,” the spokesman added.

Meanwhile, WTOL-TV reports that officials are investigating a person with swine flu symptoms in Wood County, Ohio.
