Medical experts have told parents to be aware of the symptoms.
Parents are again being warned about the unknown strain of hepatitis infecting children.
There are growing concerns about the virus after the global death toll reached 12.
So far, only one child has died from the unknown strain in Ireland, but the death toll is rising across the globe.
One other Irish child needed a liver transplant.
Only six cases have now been confirmed in Ireland, but all patients needed to be hospitalised.
It is believed the HSE is monitoring all cases, but a cause has yet to be established.
Medical experts are investigating the outbreak and believe it could be linked to the adenovirus infection.
However, this theory is still under investigation.
The HSE has urged parents to be aware of the symptoms but stressed that they should not worry too much as the virus is not extremely transmissible.
Doctors stressed that hepatitis A, B, C, and D are not responsible for the strain.
Infection rates in Ireland remain low, but the risk is still there.
The main symptoms include jaundice, diarrhea, and respiratory issues.
Other symptoms include a high fever and gastrointestinal symptoms.
If you fear your child has the unknown strain of hepatitis then you should contact your doctor immediately.
Experts stressed that parents should not delay in contacting a health professional if they suspect a case.
