Ticks are common on Seili. If possible, avoid areas with high grass or other thick vegetation and keep to the roads and lawns. A daily check for ticks is effective in preventing them from attaching. You should especially check areas of the body with thin skin.
If you find an attached tick, tweezers for removing it can be obtained at the main building. If you have difficulty detaching the tick, contact the staff for help.
You should observe the bite for a few weeks in case of a Lyme disease (borreliosis) infection. The most visible symptom is a rash that appears around the bite in a spreading circle shape. Other symptoms resemble the common cold: fever, headache, muscle aches etc. The infection is treatable with antibiotics.
