Testing For Kidney Disease
Tests to diagnose kidney disease include complete blood count, serum biochemistry, and urinalysis. These blood tests will determine if your pet is anemic, determine white blood cell counts, measure blood urea nitrogen, creatinine, and electrolytes. A urinalysis is essential for the proper interpretation of the urea and creatinine values in the serum biochemistry profile and may also provide important clues to the possible underlying cause of kidney disease. A urinalysis will also determine the specific gravity, pH, presence of blood in the urine, and the amount of protein in the urine. An evaluation of the urine sediment will determine the presence of red blood cells, white blood cells, bacteria, crystalline material, and cellular casts all of which provide information to determine the underlying cause of kidney disease in your pet. Further diagnostic tests may be recommended based on the results of these initial screening tests.
When Should You See A Doctor If You Think You Have Lyme
The rash is a pretty good indication that you may have been bitten. Take a photo of the rash and see your doctor. At this stage, treatment with antibiotics will probably work.
If you don’t have the rash but have symptoms like fatigue, fever, and headache but no respiratory symptoms like a cough, you may want to talk to your doctor.
How Ticks Find Their Hosts
Ticks can’t fly or jump. Instead, they wait for a host, resting on the tips of grasses and shrubs in a position known as “questing”. While questing, ticks hold onto leaves and grass by their lower legs. They hold their upper pair of legs outstretched, waiting to climb onto a passing host. When a host brushes the spot where a tick is waiting, it quickly climbs aboard. It then finds a suitable place to bite its host.

How Many People Get Lyme Disease
There is no way of knowing exactly how many people get Lyme disease. A recently released estimate based on insurance records suggests that each year approximately 476,000 Americans are diagnosed and treated for Lyme disease.1,2 This number is likely an over-estimate of actual infections because patients are sometimes treated presumptively in medical practice. Regardless, this number indicates a large burden on the health care system and the need for more effective prevention measures.
Q: CDC previously estimated that ~300,000 people get Lyme disease each year.3,4 Why is this new number different?
Both estimates are based in part on insurance claims data, however the 476,000 estimate uses more recent information covering the years 2010-2018. In addition, there are some differences in the detailed methods used to develop the two estimates. Its important to emphasize that 476,000 is the estimated number of people treated for Lyme disease and likely includes some patients who were not actually infected.
Q: CDC also states that approximately 35,000 cases of Lyme disease are reported each year. Why is this number so different?
Q: How often does CDC plan to estimate how many people get Lyme disease?
As additional robust sources of data become available, CDC will use them to better understand how Lyme disease affects the American public.
How Ticks Spread Disease
The tick feeding process makes ticks very good at transmitting infection:
- Depending on the tick species and its stage of life, preparing to feed can take from 10 minutes to 2 hours. When the tick finds a feeding spot, it grasps the skin and cuts into the surface. The tick then inserts its feeding tube. Many species also secrete a cement-like substance that keeps them firmly attached during the meal. The feeding tube can have barbs which help keep the tick in place.
- Ticks also can secrete small amounts of saliva with anesthetic properties so that the animal or person can’t feel that the tick has attached itself. If the tick is in a sheltered spot, it can go unnoticed.
- A blacklegged tick will attach to its host and suck the blood slowly for several days. If the host animal has certain bloodborne infections, such as the Lyme disease agent, the tick may ingest the pathogen and become infected. If the tick later feeds on a human, that human can become infected.
- After feeding, the blacklegged tick drops off and prepares for the next life stage. At its next feeding, it can then transmit the infection to the new host. Once infected, a tick can transmit infection throughout its life.
- If you remove a tick quickly you can greatly reduce your chances of getting Lyme disease. It takes some time for the Lyme disease-causing bacteria to move from the tick to the host. The longer the tick is attached, the greater the risk of acquiring disease from it.

What Causes Lyme Disease
Lyme disease is caused by bacteria. In the United States, this is usually a bacterium called Borrelia burgdorferi. It spreads to humans through the bite of an infected tick. The ticks that spread it are blacklegged ticks . They are usually found in the:
- Upper Midwest
- Pacific coast, especially northern California
These ticks can attach to any part your body. But they are often found in hard-to-see areas such as your groin, armpits, and scalp. Usually the tick must be attached to you for 36 to 48 hours or more to spread the bacterium to you.
Stage : Changing Skin
In stage 3, few signs of Lyme disease appear on the skin. Most problems occur in the heart and nervous system, and these can be serious.
Where you see signs on your skin: If you were in Europe when bit by a tick, you may see changes to your skin in this late stage. These changes usually appear on a hand or foot. Some people develop this change on both of their hands or feet. It can also occur on a knee, elbow, or elsewhere.
What the skin looks like: The skin begins to swell, and you may notice some redness. These signs are caused by having a bacterial infection for a long time. The affected skin may also feel sore.
In time, the skin starts to harden and shrink, causing deep lines to form. If you have hair in the area, it tends to fall out. The sweat glands can die, and the skin often becomes so thin that it tears easily. The medical name for this condition is acrodermatitischronical atrophicans.
In stage 3, you may also see tumors on your skin. It is believed that the long-term infection and swelling in the lymph nodes can lead to a cancer known as cutaneous B-cell lymphoma.
Skin starts to harden and shrink, causing deep lines to form
The medical name for this condition is acrodermatitis chronical atrophicans. Swelling, hardened skin, and deep lines on the foot of someone who has had Lyme disease for years.
When you see signs of changing skin and symptoms: These tend to occur months or years after you are bitten by a tick.

Stage : Late Disseminated Lyme Disease
Late disseminated Lyme disease occurs when the infection hasnt been treated in stages 1 and 2. Stage 3 can occur months or years after the tick bite.
This stage is characterized by:
- arthritis of one or more large joints
- brain disorders, such as encephalopathy, which can cause short-term memory loss, difficulty concentrating, mental fogginess, problems with following conversations and sleep disturbance
- numbness in the arms, legs, hands, or feet
Is There A Vaccine That Will Protect My Dog From Lyme Disease
A safe and generally effective vaccine is available for protecting dogs against Lyme disease. This vaccine is initially given twice, at two- to four-week intervals.
“Annual revaccination is necessary to maintain immunity.”
Annual revaccination is necessary to maintain immunity. Vaccination against Lyme disease will be determined by your pet’s lifestyle and individual risk assessment. Be sure to discuss any questions you may have regarding the type and frequency of vaccination with your veterinarian.

What Can I Do To Lower My Chances Of Getting Lyme Disease Or Any Other Disease From Ticks
Prevention begins with you! Take steps to reduce your chances of being bitten by any tick. Ticks are most active during warm weather, generally late spring through fall. However, ticks can be out any time that temperatures are above freezing. Ticks cling to vegetation and are most numerous in brushy, wooded or grassy habitats. When you are outside in an area likely to have ticks , follow these simple steps to protect yourself and your loved ones:
What Should You Do If You Find A Tick
Don’t touch the tick with your bare hand.
Use a pair of tweezers to remove the tick. Grab the tick firmly by its mouth or head as close to your skin as possible.
Pull up slowly and steadily without twisting until it lets go. Don’t squeeze the tick, and don’t use petroleum jelly, solvents, knives, or a lit match to kill the tick.
Save the tick. Place it in a plastic container or bag so it can be tested for disease, if needed.
Wash the bite area well with soap and water and put an antiseptic lotion or cream on the site.

Is There A Test For Lyme Disease
Diagnosing Lyme disease can be difficult as symptoms can vary between individuals and can also be similar to other illnesses. Health care providers use information on symptoms, potential exposure to infected black-legged ticks, and laboratory blood testing to diagnose the disease. Laboratory tests alone may not always detect Lyme disease, especially if it is in the early stages of infection. If an individual develops symptoms of Lyme disease after being bitten by a tick or visiting a known at risk area for Lyme disease, they should see their family doctor right away. The earlier a diagnosis is made, the greater the chance of a successful treatment. For more information about diagnosing Lyme disease visit www.canada.ca/Lymedisease.
Can Lyme Disease Be Treated
Yes, antibiotics are used to treat Lyme disease. Lyme disease is rarely life threatening, but if left untreated, more serious symptoms can develop. Some people experience symptoms that continue more than six months after treatment. Research continues into the causes of these persistent symptoms and possible treatment methods. If an individual suspects Lyme disease, they should consult a health care provider as soon as possible.

What Can A Workplace Or Home Do To Reduce The Presence Of Ticks
Keep the lawn and yard well maintained to prevent ticks from living near the home or workplace.
- Keep the grass mowed. Trim trees and shrubs.
- Remove leaf litter, brush, and weeds at the edge of the lawn, and around stonewalls and woodpiles.
- Clean up and seal stonewalls and small openings around the home to help discourage rodents.
- Keep stacked firewood piles and bird feeders away from buildings.
- Keep any pets, particularly dogs, out of the woods and talk to your veterinarian about tick repellents for your pets.
- Move children’s swing sets and sandboxes away from the woodland’s edge and use a woodchip or mulch foundation.
- Consider using hard landscape items such as woodchips, mulch, stones, gravel, tile, or metals.
- Create a border or barrier between the lawn, woods, or stonewalls to discourage deer and rodent activity.
- Widen woodland trails.
How Is Lyme Disease Spread
Not all deer ticks are infected with the bacteria that cause Lyme disease. Ticks can become infected if they feed on animals such as mice and other mammals that are infected. The disease can be spread when an infected tick bites a person and stays attached for a period of time. In general, the tick must be attached for 36 to 48 hours or more. Lyme disease does not spread from one person to another. Transfer of the bacteria from an infected pregnant woman to her fetus is extremely rare.

Seek Medical Care Early To Prevent Lyme Disease From Progressing
Its easy to get bit by a tick and not know it. Most people dont feel a tick on their skin or the bite. Checking your skin for ticks after spending time outdoors can help you find a tick and remove it.
Removing a tick can prevent Lyme disease. A tick must be attached to your skin for at least 36 hours to infect you with the bacteria that cause Lyme disease.
Its not always possible to find a tick, so its important to pay close attention to your skin. If you notice any signs of Lyme disease or develop a rash, get medical care right away. Ticks can cause other serious diseases, such as Rocky Mountain spotted fever.

What Are The Signs And Symptoms Of Lyme Disease
Early signs and symptoms of Lyme disease usually start three days to one month after being bitten by an infected tick. Although symptoms of Lyme disease can be different from person to person, most people experience mild flu-like symptoms soon after being bitten. A small number may have more serious symptoms, sometimes weeks after the bite.
Early signs and symptoms of Lyme disease may include:

What Happens At Your Appointment
The GP will ask about your symptoms and consider any rash or recent tick bites you know about.
Lyme disease can be difficult to diagnose. It has similar symptoms to other conditions and there’s not always an obvious rash.
2 types of blood test are available to help confirm or rule out Lyme disease. But these tests are not always accurate in the early stages of the disease.
You may need to be retested if you still have Lyme disease symptoms after a negative result.
What If A Tick Bites My Dog
The more ticks in your region, the likelier it is that your furry pal will bring them home.
Your dog is much more likely to be bitten by a tick than you are. And where Lyme disease is common, up to 25% of dogs have had it at some point.
About 10% of dogs with Lyme disease will get sick. 7-21 days after a tick bite, your dog might seem like theyâre walking on eggshells. They also might have a fever and enlarged lymph nodes. Plus, they might seem tired. Dogs also get antibiotics for Lyme.
What if my dog brings ticks into my home?
Use a tick control product on your pet to prevent Lyme disease. Also, have your dog vaccinated against Lyme.
Check your dogâs whole body each day for bumps. If you notice a swollen area, see if thereâs a tick there. If you find a tick, wear gloves while you use tweezers to separate it from your dog. Then, put it in soapy water or alcohol, or flush it down the toilet.
Use alcohol to clean the spot on your dog where the tick was attached. Keep an eye on that spot, and also on your dog to make sure theyâre behaving normally. If you notice any changes, check with your vet.

Where Does Lyme Disease Occur In Ohio
Blacklegged ticks that carry Lyme disease are most commonly found in the eastern and southern areas of the state, but are likely to occur in suitable wooded habitat throughout most or all of Ohio. On the map below, each dot represents one case of Lyme disease and is placed randomly in the patient’s county of residence. The presence of a dot does not necessarily mean that the Lyme disease infection was acquired in Ohio. The place of residence can be different from the place where the patient became infected.

What Are The Symptoms Of Lyme Disease
Symptoms can start anywhere from 3 to 30 days after the bite. They may look different depending on the stage of your infection. In some cases, you wonât notice any symptoms until months after the bite.
Early symptoms include:
All of those symptoms are also common in the flu. In most Lyme infections, one of the first symptoms youâll notice is a rash.
Without treatment, symptoms can get worse. They might include:
- Severe headache or neck stiffness
- Rashes on other areas of your body
- Arthritis with joint pain and swelling, particularly in your knees
- âDroopingâ on one or both sides of your face
- Inflammation in your brain and spinal cord
- Shooting pains, numbness, or tingling in your hands or feet
What does the rash look like?
Some Lyme rashes look like a bull’s-eye with circles around the middle. But most are round, red, and at least 2 inches across.
The rash slowly gets bigger over several days. It can grow to about 12 inches across. It may feel warm to the touch, but itâs usually not itchy or painful. It can show up on any part of your body.
How small are ticks?
Ticks come in three sizes, depending on their life stage. They can be the size of a grain of sand, a poppy seed, or an apple seed.
