KUWAIT: Well-informed health sources said that four swine flu cases were discovered amongst students of a private school in Salmiya, and that by examining other students as a precautionary measure, they were all found clear of the H1N1 virus. The sources also stressed that swine flu was no longer dangerous and that it was only as dangerous as seasonal flu, unless infected people suffer from other chronic diseases such as diabetes, blood pressure, heart or lung diseases.
