THE FIRST MEASLES death in Ireland in over 20 years was confirmed yesterday.
A man in Leinster died after contracting the disease, the HSE said.
It is understood he recently travelled to the Birmingham area where a measles outbreak has been reported.
Yesterday’s death is the first confirmed case of measles in Ireland so far this year. However, a further nine suspected cases have been reported.
These cases are currently under investigation and need to be tested in a laboratory before being confirmed as measles.
Seven of these cases have been defined as ‘possible’ measles, while two are listed as ‘probable’ measles. The suspected cases, all involving children aged nine and younger, were reported between 28 January and 3 February.
Two or more cases of measles are classed as an outbreak.
There have been relatively few confirmed cases of the disease in Ireland in recent years.
There were four confirmed cases in 2023, two confirmed cases in 2022, no cases were confirmed in 2021, and five cases were confirmed in 2020.
No deaths were reported in any of those years.
Amid a large increase in cases in Europe and a decline in vaccination rates, the HSE has recently been warning of a potential outbreak here. A taskforce has been set up to monitor and respond to the situation.
There was a nearly 45-fold increase in measles cases in Europe last year, according to the World Health Organisation (WHO). Around 42,200 people were infected with the disease in 2023, compared with 941 during 2022.
So, what exactly do people need to know about measles and how to prevent it?
What is measles?
Measles is a highly infectious disease that can cause serious complications, particularly in children under one year of age, pregnant women, and the immunosuppressed.
It typically starts with cold-like symptoms that develop about 10 days after a person gets infected. The person will get a rash a few days later.
The illness usually lasts for seven to 10 days.
What are the symptoms?
Many people with measles develop small greyish-white spots in their mouths. These appear before the rash and usually last for a few days. A rash appears around two to four days after the first symptoms and fades after about a week.
If you have these symptoms, you should seek medical advice. People are advised to phone prior to attending their GP, Emergency Department or other healthcare provider to inform them they have these symptoms.
To reduce the risk of spreading the infection to others, people should avoid:
What are the risks?
If 1,000 people get measles:
Typically, one in 1,000 people will develop encephalitis (swelling of the brain). For every 10 children who develop encephalitis, one will die and up to four will have brain damage.
One in 8,000 children under two years of age get SSPE (brain degeneration), which may be many years after measles and is always fatal.
One in 6,000 people will get a blood clotting problem.
What is the MMR vaccine?
The MMR (measles, mumps and rubella) vaccination is the best way to protect people from measles.
Two doses of the MMR vaccine are necessary to be considered fully vaccinated. The first dose is given by a GP when a child is 12 months of age. The second dose is generally given by school vaccination teams when the child is in junior infants.
If a person is unsure if they or their child has received one or both doses of the MMR vaccine, they should contact their GP. A person can also request their vaccine records from the HSE.
An MMR catch-up programme was launched through GP centres in November 2023, aimed at children and young adults who did not receive one or both doses of the vaccine.
Some GPs are also offering MMR boosters to older adults. A person should contact their GP for more information.
The HSE runs information campaigns targeting migrants who may not have received the MMR vaccine (in a number of languages), as well as members of the Travelling and Roma communities.
The overall uptake of the MMR vaccine in Ireland in 2021/2022, the latest figures available, was 87.5%. The uptake rates ranged from 74.1% in Dublin North Central to 97.2% in Dublin South East.
The WHO recommends a 95% uptake rate of the MMR vaccine to ensure herd immunity. Some people cannot be vaccinated – for health reasons, pregnancy, or if they are less than one year old – and rely on mass immunity among the general population.
“The importance of taking precautions to protect both the individual and the community from measles cannot be understated,” a spokesperson from the HSE told The Journal.
“While measles is preventable through vaccination, the virus spreads very quickly between people who are not vaccinated and can have severe consequences, particularly for babies and vulnerable groups.”
Vaccine hesitancy
A recent Irish study estimated that almost one-in-five males aged 18 and 19 are unvaccinated against measles.
The HSE spokesperson said some parents are or were hesitant to vaccinate their children “due to concerns about vaccine safety, often fuelled by misinformation”.
One of the reasons some people are reluctant to vaccinate their children is because of a now widely-discredited study from the late 1990s.
British doctor Andrew Wakefield published a study in the Lancet medical journal in 1998 that linked the MMR vaccine to autism.
However, the findings were later disproved. In 2010, the study was retracted and Wakefield was struck off the medical register in the UK.
In the past 30 years, more than 500 million doses of MMR vaccine have been given in over 90 countries.
“Experts from around the world, including the World Health Organisation, agree that there is no link between the MMR vaccine and autism,” the HSE’s spokesperson said.
“Numerous studies have proved that the vaccine is safe, however the misinformation may continue to circulate and can influence vaccine decisions.”
A decline in uptake rates may also be partially due to complacency. There have been relatively few measles cases in Ireland in recent years because of the success of the MMR vaccine.
Due to the fact cases are rare, some people “underestimate the severity” of measles and choose not to get vaccinated or vaccinate their child, the spokesperson added.
