The Southern Health Board said yesterday that four suspected cases of meningococcal meningitis in counties Cork and Kerry were all "doing fine".
"At this time of year it is quite normal to see a number of query cases", a spokesman for the board said. "They very often turn out not to be meningitis".
The spokesman said the cases under investigation are not from the same area. There have been 43 confirmed cases of meningitis in the Southern Health Board region this year, 24 unconfirmed cases and three deaths.
