The Los Angeles County Health Officer, Dr. Jonathan E. Fielding, has announced that there are two probable cases and two possible cases of swine influenza in Los Angeles County. All of the cases have recently traveled to Mexico. The two probable cases include an 11-year-old and a 52-year-old who have tested positive for influenza type-A, but have not yet been confirmed to have swine flu. The possible cases include a 69-year-old and a 60-year-old who have exhibited flu-like symptoms, but have not yet had testing. Results are expected within four days.

“These cases do not yet indicate that we have laboratory confirmed swine influenza in Los Angeles County, but it is likely,” said Jonathan E. Fielding, MD, MPH, Director of Public Health and Health Officer. “Although we have not yet confirmed a case in LA County, we have increased our surveillance activities in the past week, and we believe that we will find swine influenza here in the county. Possible swine flu cases take several days to be confirmed through lab testing.”

The Los Angeles County Department of Public Health is also investigating three possible flu clusters in three schools located in the Santa Clarita Valley and San Pedro. Laboratory results on these clusters are expected by the end of the week.

“It is important for the public to keep in mind that the best approach to prevent getting seasonal or swine influenza is good hygiene, such as frequent hand washing, covering their mouth when they cough or sneeze, and staying home if they are sick, in order to prevent the spread of any kind influenza,”
