While most tick bites do not result in diseases, some can. Some of the diseases passed on by ticks include relapsing fever, tularemia, Rocky Mountain Spotted Fever (RMSF), Q Fever and anaplasmosis. The most well-known is Lyme disease. For more information on Lyme Disease, visit BC Centre for Disease Control - Lyme Disease (Borrelia burgdorferi infection).
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 don't carry diseases, and most tick bites don't 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 6 weeks after the tick bite. Sometimes a rash or sore appears along with the flu-like symptoms. Common tick-borne diseases include:
Tick paralysis is a rare problem that may occur after a tick bite. In some parts of the world, tick bites may cause other tick-borne diseases, such as South African tick-bite fever.
The medical assessment of symptoms is based on the body parts you have.
If you are transgender or non-binary, choose the sex that matches the body parts (such as ovaries, testes, prostate, breasts, penis, or vagina) you now have in the area where you are having symptoms.
If your symptoms aren’t related to those organs, you can choose the gender you identify with.
If you have some organs of both sexes, you may need to go through this triage tool twice (once as "male" and once as "female"). This will make sure that the tool asks the right questions for you.
Are there red streaks leading away from the area or pus draining from it?
Yes
Red streaks or pus
No
Red streaks or pus
Do you have diabetes, a weakened immune system, peripheral arterial disease, or any surgical hardware in the area?
"Hardware" includes things like artificial joints, plates or screws, catheters, and medicine pumps.
Yes
Diabetes, immune problems, peripheral arterial disease, or surgical hardware in affected area
No
Diabetes, immune problems, peripheral arterial disease, or surgical hardware in affected area
Do you have a new rash or sore after being bitten by a tick?
The rash could be anywhere on the body. It may or may not be near the bite.
Yes
New rash or sore
No
New rash or sore
Does the rash cover a lot of your body?
Yes
Rash over much of body
No
Rash over much of body
Have you developed any flu-like symptoms after a tick bite, such as fever, muscle or joint pain, headache, nausea and vomiting, or a general feeling of illness?
This could happen within minutes of the bite or up to 3 weeks later.
Have you had symptoms for more than a week after a tick bite?
Yes
Symptoms for more than 1 week after tick bite
No
Symptoms for more than 1 week after tick bite
Many things can affect how your body responds to a symptom and what kind of care you may need. These include:
Your age. Babies and older adults tend to get sicker quicker.
Your overall health. If you have a condition such as diabetes, HIV, cancer, or heart disease, you may need to pay closer attention to certain symptoms and seek care sooner.
Medicines you take. Certain medicines, such as blood thinners (anticoagulants), medicines that suppress the immune system like steroids or chemotherapy, or natural health products can cause symptoms or make them worse.
Recent health events, such as surgery or injury. These kinds of events can cause symptoms afterwards or make them more serious.
Your health habits and lifestyle, such as eating and exercise habits, smoking, alcohol or drug use, sexual history, and travel.
Try Home Treatment
You have answered all the questions. Based on your answers, you may be able to take care of this problem at home.
Try home treatment to relieve the symptoms.
Call your doctor if symptoms get worse or you have any concerns (for example, if symptoms are not getting better as you would expect). You may need care sooner.
Symptoms of a severe allergic reaction can start within minutes of eating or being exposed to an allergen. While symptoms usually occur within 2 hours, in rare cases the time frame can vary up to several hours after exposure. Do not ignore early symptoms. When a reaction begins, it is important to respond right away.
Symptoms of a severe allergic reaction can vary from person to person. The same person can have different symptoms each time they have a severe allergic reaction. Symptoms can include any of the following:
Respiratory (breathing): coughing, wheezing, shortness of breath, chest pain or tightness, throat tightness, hoarse voice, nasal congestion or hay fever-like symptoms (runny, itchy nose and watery eyes, sneezing), trouble swallowing
Gastrointestinal (stomach): nausea, pain or cramps, vomiting, diarrhea
Cardiovascular (heart): paler than normal skin colour/blue colour, weak pulse, passing out, dizziness or lightheadedness, shock
Other: anxiety, sense of doom (the feeling that something bad is about to happen), headache, uterine cramps, metallic taste
A severe reaction can take place without hives, so make sure to look out for all of the signs of an allergic reaction.
Increased pain, swelling, warmth, or redness in or around the area.
Red streaks leading from the area.
Pus draining from the area.
A fever.
You may need a tetanus shot depending on how dirty the wound is and how long it has been since your last shot.
For a deep or dirty wound that has things like dirt, saliva, or feces in it, you may need a shot if:
You haven't had a tetanus shot in the past 5 years.
You don't know when your last shot was.
You have not received 3 doses of the tetanus vaccine series.
For a clean wound, you may need a shot if:
You have not had a tetanus shot in the past 10 years.
You don't know when your last shot was.
You have not received 3 doses of the tetanus vaccine series.
Certain health conditions and medicines weaken the immune system's ability to fight off infection and illness. Some examples in adults are:
Diseases such as diabetes, cancer, heart disease, and HIV/AIDS.
Long-term alcohol and drug problems.
Steroid medicines, which may be used to treat a variety of conditions.
Chemotherapy and radiation therapy for cancer.
Other medicines used to treat autoimmune disease.
Medicines taken after organ transplant.
Not having a spleen.
Tick paralysis is a rare reaction to the venom that some ticks release when they bite. Symptoms usually start 4 to 7 days after a tick attaches to your body and may include:
Tingling, numbness, or loss of feeling or movement that starts in your hands or feet.
Trouble swallowing or talking.
Double vision.
Loss of movement in your face.
Removing the tick stops the release of the venom and reverses the problem.

Most ticks don't carry diseases, and most tick bites don't cause serious health problems. The sooner ticks are removed, the less likely they are to spread disease.
Some ticks are so small that 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.
Use fine-tipped tweezers to remove a tick. If you don't have tweezers, put on gloves or cover your hands with tissue paper, then use your fingers. Do not handle the tick with bare hands. If the mouthparts break off and remain in the skin, remove them with tweezers or, if you are unable to remove them easily, see your health professional as soon as possible.
Do not try to smother a tick that is attached to your skin with petroleum jelly, nail polish, gasoline, or rubbing alcohol. This may increase your risk of infection.
Do not try to burn the tick while it is attached to your skin.
Put the tick in a dry jar or ziplock bag and save it in the freezer for later identification if necessary.
Wash the area of the tick bite with soap and a lot of warm, clean water.
Apply a thin layer of antiseptic cream, lightly to the wound. It will keep the bite from sticking to the bandage.
After you remove the tick, wash your hands really well with soap and water.
Save the tick in a container with a tight fitting top:
Dampen a small cotton ball and put it into the tick container, if the tick is still alive.
An intact dead tick may also be identified and tested.
When you return home from areas where ticks might live, carefully examine your skin and scalp for ticks. Check your clothing, outdoor gear, and pets, too. Remove any ticks you find. Then put your clothing in a clothes dryer on high heat for 10 minutes to kill any ticks that might remain.
Home treatment to help relieve pain and itching
Apply an ice pack to your bite for 15 to 20 minutes once an hour for the first 6 hours. When you are not using ice, keep a cool, wet cloth on the bite for up to 6 hours.
An antihistamine medicine, such as a non-drowsy one like loratadine (Claritin) or one that might make you sleepy like diphenhydramine (Benadryl), may help relieve itching, redness, and swelling. Don't give antihistamines to your child unless you've checked with the doctor first.
A spray of local anesthetic containing benzocaine, such as Solarcaine, may help relieve pain. If your skin reacts to the spray, stop using it.
Calamine lotion applied to the skin may help relieve itching.
After the first 6 hours, if there is no swelling, try putting a warm face cloth on the bite for comfort.
Medicine you can buy without a prescription
Try a non-prescription medicine to help treat your fever or pain:
Aspirin (also a non-steroidal anti-inflammatory drug), such as Entrophen
Talk to your child's doctor before switching back and forth between doses of acetaminophen and ibuprofen. When you switch between two medicines, there is a chance your child will get too much medicine.
Safety tips
Be sure to follow these safety tips when you use a non-prescription medicine:
Carefully read and follow all directions on the medicine bottle and box.
Do not take more than the recommended dose.
Do not take a medicine if you have had an allergic reaction to it in the past.
If you have been told to avoid a medicine, call your doctor before you take it.
If you are or could be pregnant, do not take any medicine other than acetaminophen unless your doctor has told you to.
Apply an insect repellent safely. Use insect repellents according to the directions on the label, particularly when applying repellent to children.
Use a lower-concentration repellent on children.
Do not put repellent on small children's hands, since they often put their hands in their mouths.
Wash the insect repellent off with soap and water after returning indoors.
Use products that contain 0.5% permethrin on your clothing and outdoor gear, such as your tent. You can also buy clothing already treated with permethrin. Permethrin is not available as an insect repellent in Canada, but travel health clinics may be able to advise you on how to buy permethrin or permethrin-treated gear.
Cover as much of your skin as possible when working or playing in grassy or wooded areas. Wear a hat, a long-sleeved shirt, and long pants with the legs tucked into your socks. Keep in mind that it is easier to spot ticks on light-coloured clothes. If you think you may have a tick on your clothing, put your clothing in a clothes dryer for 10 to 15 minutes to kill the tick.
Wear gloves when you handle animals or work in the woods.
Take steps to control ticks on your property if you live in an area where Lyme disease is prevalent. Clearing leaves, brush, tall grasses, woodpiles, and stone fences from around your house and the edges of your yard or garden may help reduce the tick population and the rodent population that the ticks depend on. Remove plants that attract deer, and use barriers to keep deer—and the deer ticks they may carry—out of your yard. Treating yards with chemicals that kill ticks (ascaricides) is sometimes effective but exposes you and your pets to chemicals that may not be safe. You may choose to treat your lawn for ticks with nonchemical or environmentally safe methods instead. Call your local landscaping nursery or local health unit for more information.
Stay away from tick-infested areas.
For information on how to specifically prevent Lyme disease, see the topic Lyme Disease.
You can help your doctor diagnose and treat your condition by being prepared to answer the following questions:
When were you bitten? How many times were you bitten? If you saved the tick, bring it with you to your doctor's appointment. If not, be prepared to describe the tick.
What are your main symptoms?
When did your symptoms begin? How have your symptoms developed, progressed, or changed since the bite?
