A DUBLIN HOSPITAL has urged visitors to stay away after a new outbreak of the virus that hit two other hospitals in the capital over Christmas.

It’s understood a number of wards at Connolly Hospital in Blanchardstown are affected by cases of norovirus, which can cause violent vomiting and diarrhoea.

Visitors are being asked to stay at home unless absolutely necessary, and no children are permitted on the general wards at any time.

The restrictions were first introduced on Monday after the outbreak began on Sunday.

St Vincent’s and Beaumont hospitals were forced to introduce similar restrictions over the holiday period. More than 100 people were affected by that previous outbreak.

Norovirus is extremely contagious and has no specific treatment. The HSE has previously advised anyone concerned about infection to wash their hands frequently, and clean and disinfect any surfaces that may be contaminated.

Similarly, any clothes or bedsheets which come into contact with infectious substances should be immediately removed and washed.
