Tick bites and lyme disease
Habits
There are a number of different types of ticks in Britain, all of which need occasional blood meals to survive. Each type of tick usually feeds off a particular type of animal. When this 'host' animal is not available, the tick will seek an alternative supply of blood and humans may be bitten.
Food
Once on the skin, the tick injects its saliva which prevents the blood from clotting and makes the bite painless. It buries its head beneath the skin and remains attached for about two days feeding slowly for the first 24-36 hours and then rapidly gorging itself. During this stage, it tick becomes much bigger. After feeding, it will drop off the body.
Lyme disease
In 1986 doctors at Southampton General Hospital discovered that bites from a tiny tick which normally lives on deer can cause illness in humans. Lyme disease can cause flu-like symptoms (tiredness, headaches, pain in joints and muscles). If untreated it can, in severe cases, lead to arthritis and a stiff neck and can be mistaken for meningitis. The risk of getting lyme disease is small, with one in every 5,000 tick bites likely to lead to it.
How to Remove the Tick
If you've been bitten by a tick and it's still attached to your skin, remove it as soon as possible to reduce your risk of picking up illnesses such as Lyme disease .
To remove a tick:
- Use a pair of tweezers that won't squash the tick (such as fine-tipped tweezers), or use a tick removal tool (available from pet shops or vets).
- Grip the tick as close to the skin as possible to ensure the tick's mouth isn't left in the skin.
- Pull steadily away from the skin without twisting or crushing the tick
- Wash your skin with water and soap afterwards, and apply an antiseptic cream to the skin around the bite.
Don't use a lit cigarette end, a match head or substances such as alcohol or petroleum jelly to force the tick out.

What to do Following a Tick Bite
Most tick bites will require no further action. The first sign to watch out for is a red skin rash which starts at the site of the tick bite and spreads outward in a ring shape. This rash can be up to 50 cm (20 inches) in diameter. It may be followed by:
- a headache
- fever/chills
- a stiff neck
- pain in the joints
- difficulty remembering and concentrating.
If you get any of these symptoms, see doctor as lyme disease can be treated with antibiotics. The earlier it is diagnosed, the easier it is to treat. All doctors in the New Forest area are aware of it and will know what action to take. If you are a visitor to the area and symptoms develop after your return home, show your doctor this information.
