Winter viruses are starting to rear their head as the weather turns colder, with a single outbreak of norovirus causing 33 people to fall ill.
The outbreak was detected at a childcare centre in eastern Ireland at the end of October and a further five cases were linked to a hospital outbreak in the north east of the country two weeks after.
Norovirus is known as the winter vomiting bug as it thrives during the colder season and can cause some nasty symptoms.
It is highly contagious and easily spread through close contact with people who have been infected.
Public Health England (PHE) advises staying away from work, and keeping children off school or from nursery, for at least 48 hours if you experience any symptoms of the bug.
The bug will usually pass within two to three days and is best treated through plenty of rest and by drinking lots of fluids to avoid dehydration.
With cases of norovirus typically increasing during the winter, these are all of the symptoms to look for and how the bug is spread.
