Up up 19 cases of measles have already been reported throughout the country in recent weeks.
It is believed the source of the infection came from central Europe where measles outbreaks are occurring in widespread measures.
Consultant in Public Health Dr Kevin Kelleher said:
“The HSE are looking to raise public awareness around the signs and symptoms of the condition and ensure anyone with concerns addresses them immediately in order to receive a rapid diagnosis.”
“Measles is highly infectious, and if cases are isolated early, the risk of transmission to vulnerable individuals decreases. The time between exposure to the virus and developing measles rash is normally 14 days (range 7-21 days). People are infectious from 4 days before rash starts until 4 days after.”
Those most at risk are those who are not fully vaccinated with two doses of MMR and babies younger than 1 year old.
