The HSE has issued a warning in Ireland against Lyme disease.
Lyme disease is mainly spread by ticks and people who engage in outdoor activities are likely to be more at risk of being in contact with the disease-carrying ticks.
The HSE said that those who work in forest or grassy areas should be extra aware of tick bites by using insect repellent, wearing long clothing and checking for ticks after a day outside.
In a small number of cases, Lyme disease can 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."
