The Panamanian Health Ministry reported four new cases of the A/H1N1 flu on Monday, bringing the confirmed cases in the country to 59.

Of the 59 cases, 55 were in Panama City, one in Colce province and three in Colon province, the ministry said.

Thirty-one of the cases were women and 28 were men. More than 50 percent of the infected were patients under 15 years old.

None of the patients have been hospitalized, but all are under strict sanitary control and have received specialized medical treatment, authorities said.

The first confirmed A/H1N1 flu case in Panama was reported on May 8.

To prevent the spread of the disease, a campaign has been launched in the country, calling the public to wash hands frequently and using facial masks. Three schools, where students had shown A/H1N1 flu symptoms, have been closed.
