(AP) - Health officials have confirmed another case of swine flu in New Jersey.

The patient is a 12-year-old Camden County girl. Health officials say she traveled to an affected state. She did not go to school while sick and has recovered.

With Tuesday's addition, there are still seven confirmed cases in New Jersey because health officials say a clerical mistake was made in one case previously reported as confirmed. The federal Centers for Disease Control and Prevention now says a 22-year old Bergen County woman did not have the swine flu strain.

A Burlington County school that closed as a precaution after two students showed flu-like symptoms will reopen Wednesday. The Hainesport Township School students tested negative for swine flu.
