'Kissing disease'

The HSE also shared information on how to stop the spread of the illness that they say is often referred to as the "kissing disease".

They said: "Glandular fever is very infectious. It's passed in saliva and can be spread through:

  • kissing – it is often referred to as the 'kissing disease'
  • exposure to coughs and sneezes
  • sharing eating and drinking utensils, such as cups, glasses and unwashed forks and spoons

And recommend people to wash their hands regularly, wash bedding that might have spit on it, avoid kissing and not to share any cooking or eating utensils.


There is no cure for glandular fever and it gets better by itself but there are a few things you can do to ease symptoms.

The HSE recommend rest and sleep, to drink plenty of fluids to avoid dehydration and to take painkillers like paracetamol or ibuprofen.

Antibiotics will not help because the illness is caused by a virus.
