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 and 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.

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 there has been no increase 

compared to what we saw before the Covid-19 pandemic. 

 

Information about managing illnesses of concern will continue to be updated on hse.ie over 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 

These measures that we all got used to with Covid-19 are still important. They 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. Visit 

www2.hse.ie/screening-and-vaccinations/covid-19-vaccine/get-the-vaccine/children/ 

The most important ways to prevent the spread of all infections are: 

• making sure anyone unwell stays at home 

• children and adults are up to date with their recommended vaccines, including flu
