RE: Significant increase in viral infections and Group A Strep infections

DATE: 7th December 2022

There has been a large increase in general viral infections among children and young people this winter. There have also been recent concerns about a rare bacterial infection. This infection is iGAS (an invasive Group A Streptococcal infection). It is also known as Group A Strep.

Significant increase in viral infections
We have seen a significant increase in the usual winter viral infections. This includes an increase in flu. This is because children are mixing together more. In previous years social contact was much reduced. This in turn reduced the rates of routine infection.

Typical symptoms of viral infections

Symptoms of viral infections typically include:

  •  runny or blocked nose
  •  mild fever
  •  cough
  •  lethargy (tiredness)

Many children with viral infections also have a generalised rash.
Most children with viral infections can safely be cared for at home.
More information can be found at https://www2.hse.ie/conditions/colds-coughs-children/

Group A Strep and related bacterial infections
There have been cases of serious bacterial infections, specifically Group A Strep.
Severe infection is rare. Group A Strep more commonly causes infections such as:

  • tonsillitis
  • scarlet fever
  • skin infections

Ireland has seen cases of more serious infections recently. But so far the rate of serious infection is below the level seen before the Covid-19 pandemic.

Information about managing illnesses of concern will continue to be updated on hse.ie over the coming days and weeks.

Important messages for families and children regarding any infections:

1) The most important measure is to stay home if you are unwell.
Many children might have a runny nose or a slight cough in winter season. However, if a child is feeling unwell they should be at home. For example, they may have:

  • fever
  • cough, and
  • sore throat

They should stay at home until those symptoms have finished.

See https://www2.hse.ie/conditions/colds-coughs-children/

Children with symptoms are more likely to spread infections. For example, they may spread flu or bacterial infections. Staying home when unwell will help prevent spread to other children, families and staff.

2) Infection, prevention and control measures

– Cover coughs and sneezes
– Keep hands clean

Many of the measures that we all got used to with Covid-19 are still important. Hygiene measures such as these should be encouraged for everyone. These measures help stop the spread of infection.

3) Vaccination
Making sure your child is up to date on all recommended vaccinations will help:
– stop your child getting an infection and
– make them less likely to be unwell if they do get an infection.

Routine childhood vaccinations protect against many significant viral and bacterial infections.
There is no vaccine against many viral illnesses or Strep A.

Flu vaccine
The nasal spray flu vaccine is available for children aged 2 to 17 years. It helps protect against severe infection with flu and onward spread.
See https://www2.hse.ie/conditions/flu/childrens-flu-vaccine/

Many adults are also recommended to have the flu vaccine.

Vaccination for Covid-19 is still available.


  • The most important ways to prevent the spread of all infections are making sure   anyone unwell stays at home.

If you are concerned your child may be unwell, please check hse.ie.

There is information on coughs, colds, fever, rashes and symptoms of concern. There is advice on when to contact your GP or go to a hospital emergency department. https://www2.hse.ie/conditions/colds-coughs-children
