Ireland has recorded its first case of Clade I Mpox, a more severe and potentially deadlier strain of the virus, after a patient returned from abroad. Health officials are now on high alert as concerns grow over the potential for further spread.

What Is Clade I Mpox and Why Is It Dangerous?

Mpox, formerly known as monkeypox, has had multiple outbreaks worldwide, but Clade I is significantly more severe than the more common Clade II strain. Studies indicate that Clade I has a higher fatality rate, spreads more efficiently among humans, and has the potential to cause more long-term health complications.

Medical expert Dr. Seán Gallagher explains:

“Clade I is not the same as previous cases seen in Europe. This strain has been linked to higher hospitalisation rates and complications, making early detection and containment crucial.”

First Case in Ireland – How Did It Arrive?

The patient, whose identity remains undisclosed, contracted the virus abroad before returning to Ireland. The Health Protection Surveillance Centre (HPSC) confirmed that the case has been isolated, and contact tracing is underway to prevent further transmission.

A statement from health officials reassured the public:

“The case is being closely monitored, and we are working with international health bodies to assess the situation. No further cases have been confirmed at this time.”

However, concerns are rising as Mpox can have an incubation period of up to three weeks, meaning more cases could emerge in the coming days.

Symptoms of Clade I Mpox – What to Watch For

Clade I Mpox presents similar but often more intense symptoms compared to previous cases. Common symptoms include:

• Painful skin lesions and rashes
• Fever and chills
• Severe fatigue and muscle aches
• Swollen lymph nodes
• Respiratory issues in severe cases

Unlike Clade II, which has been manageable with antivirals and vaccines, Clade I has been associated with higher rates of severe illness, especially in immunocompromised individuals.

How Is It Transmitted?

Mpox spreads primarily through close physical contact, including:

• Skin-to-skin contact with lesions or infected surfaces
• Respiratory droplets from prolonged exposure
• Contaminated clothing or bedding
• Sexual contact (a significant factor in recent outbreaks)

Is There a Risk of a Larger Outbreak in Ireland?

While officials downplay the likelihood of widespread transmission, some experts warn that underestimating Clade I could be dangerous. Epidemiologist Dr. Fiona Murphy cautioned:

“A single case should not cause panic, but it should demand immediate action. If Clade I enters vulnerable populations, we could see hospitalisations increase.”

The biggest concern is Ireland’s limited supply of Mpox vaccines, which were already stretched during previous outbreaks.

Government Response – Is Ireland Prepared?

Public health authorities have initiated contact tracing and quarantine measures for anyone potentially exposed. However, there are growing calls for:

• Immediate procurement of additional vaccines
• Expanded testing to detect asymptomatic cases
• Clearer public guidance on transmission risks

The Department of Health released a statement urging caution:

“Individuals who have traveled recently and are experiencing symptoms should seek medical advice immediately. Avoid close contact with others until cleared by a doctor.”

Lessons from Previous Outbreaks – Are We Doing Enough?

In 2022, Europe faced a widespread Mpox outbreak, leading to thousands of cases and urgent vaccination rollouts. Experts argue that Ireland cannot afford to wait for more infections before acting.

One frustrated public health advocate noted:

“Why are we always reacting instead of preparing? We knew Clade I was circulating in other countries—why weren’t stronger measures in place before now?”

What Happens Next?

With no additional confirmed cases yet, officials hope that rapid containment efforts will prevent further spread. However, the next two weeks are critical in determining whether Ireland will face a larger Mpox outbreak.

The public is urged to remain vigilant—especially those who have traveled recently—and to follow any health advisories issued by the government.
