In addition to the three confirmed cases of swine flu in Dallas County, there are now six probable cases as well, health officials said Tuesday.
One of the probable cases, where a lab test shows the subject positive for flu but may not indicate the particular strain, had a connection to Canyon Creek Elementary School -- which has been closed the remainder of the week because of swine flu. Two other cases mentioned Monday were family members of previously confirmed cases who had begun showing flu symptoms.
In addition to the probable cases, Carlo said that there were a number of cases labeled suspicious -- where someone shows flu symptoms, but has not yet been tested or where test results were inconclusive.
Carlo said there were seven cases in Dallas County where they believed to have found swine flu, only to realize it was seasonal flu after further examination.
This year's seasonal flu has been shown to be Tamiflu-resistant, but the drug can still be used to treat swine flu, according to Carlo.
All of Dallas County's probable cases have been referred to the Centers for Disease Control and Prevention. The CDC lists six cases of laboratory-confirmed cases of swine flu in Texas.
In Tarrant County, health officials are investigating six probable cases of swine flu, five of which were new on Tuesday. None of the cases have been confirmed. Lab results from the CDC in all six cases are pending, health officials said.
According to the CDC, there are everyday actions people can take to stay healthy.
Officials ask anyone with flu symptoms to visit their doctor.
