Ticks are found in nature
Ticks are small insects that are found in nature between March and October. High grass is one example of where you might find ticks. Ticks suck blood from people and animals. A tick looks like a small spider and is 1–4 millimetres long. A tick may grow bigger in size once it has sucked blood.
Ticks can spread diseases
Ticks are not dangerous, but they can spread diseases. One of these diseases is TBE, tick-borne encephalitis, which can cause inflammation, swelling, of the brain. Another disease is called Lyme disease, and this can affect the skin, joints, and nerves. You can get vaccinated against TBE, but not against Lyme disease.
There is a greater risk of infection if the tick stays attached to the skin for a long time. You should therefore remove the tick as quickly as possible.
