The HSE has issues a warning against Lyme disease.

Lyme disease is a bacterial illness caused by bacteria. It is spread by tick bites and can affect the skin, joints and nervous system. The infection is common and the HSE has now warned people who frequent the outdoors to be extra cautious. The HSE says 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 and checking for ticks after a day out. While most experience mild flu like symptoms, in some cases the disease can cause heart and nervous system disease. "Lyme disease has been notifiable in Ireland since 2012 and, since then, there have been between eight and 18 cases notified in Ireland each year” said Dr. Paul McKeown. "However, as many people will not be aware that they are/have been infected or may not seek medical help when unwell, the true incidence of Lyme disease is not accurately known. It is likely that there are at least 50-100 cases in Ireland every year," he concluded.
