Pleasanton Unified School District spokeswoman Myla Grasso said Friday afternoon that students and a district staff member have been tested for the swine flu.
"We have been informed that 13 students and one staff member have been tested for the H1N1 virus, but we have not been informed those are positive," she said.
Grasso said she didn't know when the results would be back.
Pleasanton school officials yesterday notified parents that they should keep their children home if they have flu-like symptoms and to quickly advise their student's school that the child is experiencing those symptoms when the absence is called in.
The notice came as schools reported that several of their students are now at home recovering from flu-like symptoms.
"These symptoms include a fever over 100 degrees and sore throat or cough," said Myla Grasso, the district's Public Information Officer. "Other symptoms may include loss of appetite, lethargy, runny nose, aches, nausea, vomiting, or diarrhea. Families are encouraged to contact their health care provider if their child experiences these symptoms."
The warning came on the same day that local health officials announced the first case of swine flu in San Francisco.
The San Francisco Department of Public Health announced that the state public health department has confirmed that a local boy who recently traveled to Mexico has contracted the virus. Health officials said the boy is not in school.
According to Grassso, the Pleasanton district's policy calls for students who have been ill to not return to school until they have been fever-free for 24 hours without the aid of a fever reducer such as Tylenol or Advil. Other symptoms should have improved significantly as well.
Grasso said the school district is monitoring absences at all sites daily.
"Other steps we are taking include the provision of additional hand sanitizer and cleaning wipes in classrooms," she added. "We are in close communication with the city of Pleasanton and Alameda County public health services."
"Steps you can take to help prevent the spread of flu include frequent and thorough hand washing, coughing or sneezing into a tissue, avoiding touching eyes, nose, or mouth, avoiding contact with sick people, and staying home from school or work if you are sick," Grasso said in a message sent to parents.
On Friday, Alameda County Department of Health spokeswoman Sherri Lewis said there is now one probable case of the H1N1 virus.
"It is a woman in her 50s with no recent travel to Mexico," she said, adding that she could not disclose what city the woman lives in.
Lewis said more specimen are being sent to a Richmond lab for further testing and that "the cases are increasing by the day."
New cases also being reported in Solano and San Mateo counties, according to health officials.
The Solano County case is a 50-year-old Vacaville man. Two other probable cases were reported by health officials in San Mateo County, who plan to release details at a news conference later this morning.
Two Bay Area schools have been closed in response to the swine flu outbreak -- Branham High School in San Jose and Highlands Elementary School in Pittsburg -- after probable cases were reported among students.
At least four probable cases of swine flu have been detected in Santa Clara County, three in Contra Costa County and two in Marin County.
Suspected swine flu cases were first reported in the Bay Area on Tuesday, but the outbreak, believed to have originated in Mexico, was first reported in the U.S. in late March in Southern California and Texas, according to health officials.
It is spread mainly person-to-person through coughing and sneezing.
