Ticks are small spider-like animals (arachnids) that bite to fasten themselves onto the skin and feed on blood. Ticks live in the fur and feathers of many birds and animals. Tick bites occur most often during early spring to late summer and in areas where there are many wild animals and birds.
Most ticks do not carry diseases, and most tick bites do not cause serious health problems. But it is important to remove a tick as soon as you find it. Removing the tick's body helps you avoid diseases the tick may pass on during feeding. Removing the tick's head helps prevent an infection in the skin where it bit you. See Home Treatment for the best way to remove a tick.
Usually, removing the tick, washing the site of the bite, and watching for signs of illness are all that is needed. When you have a tick bite, it is important to determine whether you need a tetanus shot to prevent tetanus (lockjaw).
Some people may have an allergic reaction to a tick bite. This reaction may be mild, with a few annoying symptoms. In rare cases, a severe allergic reaction (anaphylaxis) may occur.
Many of the diseases ticks carry cause flu-like symptoms, such as fever, headache, nausea, vomiting, and muscle aches. Symptoms may begin from 1 day to 3 weeks after the tick bite. Sometimes a rash or sore appears along with the flu-like symptoms. Common tick-borne diseases include:

Most ticks do not carry diseases, and most tick bites do not cause serious health problems. The sooner ticks are removed, the less likely they are to spread disease.
Some ticks are so small it is hard to see them. This makes it hard to tell whether you have removed the tick's head. If you do not see any obvious parts of the tick's head in the bite site, assume you have removed the entire tick, but watch for signs of a skin infection.
When you return home from areas where ticks might live, carefully examine your skin and scalp for ticks. Check your pets, too.
