The HSE has issued a warning against Lyme disease.
The infection is spread by ticks, with people engaged in outdoor pursuits are most at risk.
The HSE has said ramblers, campers, mountain bikers, and others who work and walk in forest or grassy areas should be vigilant against tick bites by using insect repellent, wearing long trousers and sleeves as well as checking for ticks after a day out.
Lyme disease can, in a small number of cases, cause severe debilitating heart and nervous system issues.
"Ticks are tiny spider like creatures that feed on the blood of mammals and birds and will also feed on the blood of humans and occasionally dogs," said Dr. Paul McKeown, HPSC Specialist in Public Health Medicine.
"Ticks are more numerous and more active in the summer months and protecting against tick bites protects against Lyme disease. The most effective way to prevent Lyme disease is by preventing tick bites."
