AN outbreak of swine flu at a national school in Cavan is being managed by the Health Service Executive.

Scientists believe they have found the answer to why bird flu does not spread easily between people.

The bird flu virus that infected a Vietnamese girl was resistant to the main drug that’s being stockpiled in case of a pandemic, a sign that it’s important to keep a second drug on hand as well, a researcher said tonight.
