Three probable cases of swine influenza have now been reported in Philadelphia.
Further testing in those cases -- a two-year-old child, a 46-year-old woman and a 25-year-old man -- must be done to confirm swine flu, according to the Pennsylvania Department of Health.
The child became ill on March 23, before the current outbreak was recognized in the United States. Since that time, the child has recovered fully from the illness.
Initial tests showed that the child had the influenza A infection, but the Philadelphia Department of Public Health requested that the child's case be reviewed further in light of the current swine flu outbreak. Results have not yet been confirmed.
Further information on the two adult cases was not immediately available.
The only other case of probable swine flu virus in Pennsylvania was reported Thursday in Montgomery County. That case also has not been confirmed.
Penn is "actively monitoring the influenza outbreak," according to a University-wide e-mail sent yesterday, and is working with both city and state officials to keep the community updated and prepare for the possibility of further cases in the area.
The University has also suspended all Penn-sponsored programs to Mexico until further notice after the Centers for Disease Control and U.S. State Department issued travel warnings for all non-essential travel to Mexico.
As of Thursday afternoon, there are 109 confirmed cases of swine flu in the United States, and one person has died from the infection, according to the CDC.
Four students at the University of Delaware tested positive for swine flu, according to an alert posted on the school's Web site. Twelve other students at the university are suspected of having swine flu.
Common symptoms of swine flu include fever greater than 100 degrees, body aches, coughing, sore throat, respiratory congestion and diarrhea or vomiting. Anyone who has recently traveled to an affected area, come in contact with someone who has swine flu or is experiencing these symptoms should seek medical attention immediately.
