Lyme disease can be contracted by a bite from an infected tick. The most common symptom is a "bullseye" shaped rash around the bite.
They can be found in long grass, woodland and heath in places like the Lake District and the North York Moors.
Many people experience flu-like symptoms or headaches and the disease can be treated with antibiotics.
Left untreated it can lead to long term health problems such as neurological symptoms, joint problems or symptoms similar to chronic fatigue.
A person with Lyme disease isn't contagious but there has been debate as to whether it can be passed from mother to child in the womb. Many charities have called for more research.
It's estimated there are up to 3,000 cases of Lyme Disease in England and Wales every year, although 20 per cent are contracted abroad.
The best way to prevent Lyme disease is to avoid being bitten, wearing long-sleeved shirts, tucking socks into trousers.
