Transcript of Lyme Disease

Lyme Disease also known as Borreliosis, or Bannwarth syndrome (which is it's medical term) What Is Lyme Disease? Lyme disease is a bacterial infection spread through the bite of the blacklegged tick the disease is caused by bacteria called BORRELIA BURGDORFERI the ticks pick up the bacteria when they bite mice or deer that are infected with Lyme disease you can get the disease if you are bitten by an infected tick, because they transmit the bacteria into your body Stages and Symptoms Stage One Stage Two Stage Three Early Localized Lyme Disease The infection is not yet widespread throughout the body. The symptoms can begin days or weeks after infection. Symptoms May Include: body-wide itching
muscle pain
general ill-feeling There may also be a "bull's eye rash"
(a flat or slightly raised red spot at the site of the tick bite. Often there is a clear area in the center, and it can be quite large, expanding in size) Symptoms come and go. Untreated, Lyme disease can spread to the brain, heart and joints. Early Disseminated Lyme Disease The bacteria have begun to spread throughout the body. These symptoms may occur weeks to months after the initial tick bite. Symptoms May Include: paralysis or weakness in the muscles of face
muscle pain and pain or swelling in the knees and other large joints
heart problems, such as skipped heart beats (called Papitations) Late Disseminated Lyme Disease Symptoms can occur months or even years after the infection. The bacteria have spread throughout the whole body. Symptoms May Include: abnormal movement
muscle weakness
numbness and tingling
speech problems The disease can be fatal, but it's rare that people die from it, though some still have. Usually, if you take care of yourself and take the antibiotics to counteract the disease, you should be fine. The History of Lyme Disease Lyme Disease is the most common tick-borne infection in North America and Europe, but isn't common in Canada. The disease was first officially identified in the United States in the 1970s in the town of Lyme, Connecticut. It began with a local artist named Polly Murray. By 1975 Murray had been suffering for 10 years, but doctors could find no explanation to her condition. The actual spirochete responsible for Lyme disease was not discovered until 1981, when microbiologist Willy Burgdorfec studies a sample of ticks. He dissected the ticks and found that 60% of them contained a strain of spirochete bacteria in their midguts. That's when he suspected he had found the cause of what was known as Lyme disease. The agent causing Lyme disease had finally been found, so in 1983, at the International Symposium of Lyme Disease, the Lyme bacterium was named Borrelia burgorferi in honor of its discoverer and his research. Definitions spirochete: Any member of an order of bacteria characterized by a long spiral shape, many of which cause illness How Infection Occurs Although people get infected through the bite of a tick, the tick isn't the original host, or reservoir, of the bacteria. Instead, it's the vector. A tick becomes infected with the bacteria when it feeds on a source that naturally carries
Lyme-causing strain of Borrelia, such as a chipmunk, shrew, or white-footed mouse. The bacteria then lodges in the intestines of the tick. When the infected tick bites a person and begins to feed, Borrelia spirochetes are transferred from the tick's intestines through its saliva and into the person's bloodstream. Lyme Disease is a vector-borne disease, which means that it's transmitted from one host to another by a vector, or a carrier. Definitions vector: An organism that transmits a bacterium or virus that causes a disease to another organism Is It Contagious? According to the Centers for Disease Control and Prevention (CDC), there is no evidence that Lyme disease can be transmitted from person to person through touching, contact, or if it can be transmitted through air, water or food. It's also important to know that previous infection with Lyme disease does not lead to immunity, So if you've gotten it before, you can get it again, which means that it's always good to watch what you are doing and where. Prevention Tips Here's some advice that you should think about if you don't plan on getting Lyme disease! humans, as well as pets, can carry around ticks and contract the disease, so make sure to check your cat or dog after a walk avoid doing outside activities that increase tick exposure, such as gardening, hiking, or hunting in an area where Lyme disease is known to occur stay away from wooded or bushy areas, try not to walk in high grasses and leafy litter, and take precautions to avoid direct
contact with ticks walk in the center of trails whenever possible when walking in grassy areas, spray all exposed skin and your clothing with insect repellant Affects On The Body Lyme disease not only hurts the patient, mentally, but physically too. Here are some of the cells within the human body that are affected by the disease: Lyme disease that continues to develop inside the body can begin to form toxins that can be fatal. Flu like symptoms and extreme pain in the muscles and joints can make it difficult to perform everyday functions. Even with antibiotic treatment, the damage to infected parts of the body may be irreversible. Speech problems can begin to develop and worsen, causing communication to be a problem for the infected person. Deterioration of the muscles can also cause a person to become bed-bounded. Epidermis and Dermis (Skin Cells)
- if untreated by antibiotics, the disease may spread to the bloodstream, forming skin rashes, or the person may even develop a chronic skin condition Nerve Cells
- if the disease persists for days or weeks, neurological tissue is likely to display symptoms
- the most common examples are the conditions of Bell's Palsy, a loss of facial muscle tone, characterized shooting pains, neck stiffness, sensitivity to light, memory loss, sleep disturbances, or changes in mood Cardiac Cells
- if the disease lasts for several months, it may spread to the heart Joint and Muscle Tissue
- after several months, the disease may be manifested in joints and muscles, primarily in the form of myalgia and arthritis
- Lyme arthritis is usually most noticeable in the knees
- in addition, Baker's crysts may form and rupture in joints Is There A Vaccine? In 1998, the FDA (Food and Drug Administration) approved a vaccine for Lyme Disease called LYMErix Although some people reported getting sick from the vaccine, the FDA found no evidence that it was dangerous. However, in February 2002, the makers of the vaccine pulled it off the market due to poor sales. Currently, there is no available vaccine on the market for Lyme disease. We still need to find a successful vaccine that can prevent the disease. Treatments Patients are diagnosed from a series of blood tests, and if the results come back as positive, then the patient can take one of two treatment plans. Antibiotic Treatments If it's determined that a person is in fact suffering from Lyme disease, he or she is given antibiotics, which are drugs used to treat infections caused by bacteria. Specific antibodies that docors recommend may include doxycycline, amoxicillin, or cefuroxine axetil, given orally, which means in a form that can be swallowed, such as a pill or capsule. Alternative Therapies Some patients who continue to experience symptoms after being treated for Lyme disease do not want to seek further medical treatment, so these patients sometimes turn to alternative treatments in an effort to feel better. These treatments can range from fairly simple, such as taking mineral supplements, to more complex. try natural treatments Although, the long term financial burden can be catastrophic for some patients. The Stigma Although Lyme Disease is the most common tickborne disease in the world, disagreement about diagnosis and treatment may be a source of stigma for those with the disease. A study was conducted to test and examine both helpful and stigmatizing experiences among Lyme disease patients with persistent symptoms. The study concluded that Lyme disease-related stigma manifests in multiple ways and is perceived by patients with persistent symptoms as interfering with adequate medical care. In contrast, listening to patients and providing greater opportunities for support are perceived as ways in which healthcare providers. Protest Against The IDSA Lyme Disease Guidelines Definitions sigma: A mark of disgrace associated with a particular circumstance, quality, or person On October 22nd, 2011, Lyme patients from around the country gathered on the sidewalks in front of the Boston Convention Center at the annual IDSA meeting. Over 80 people showed up to protest the guidelines written by the IDSA (Infectious Disease Society of America) on how to treat Lyme disease. Support For Lyme there are many small groups out there, trying to get more and more people to realize what Lyme Disease really is - Groups Such As . . . Lyme Disease Awareness
CanLyme (Canadian Lyme Disease Foundation)
Northcoast Lyme Disease Support Group CanLyme says that Lyme Disease is a serious threat. It's on the rise in Canada, yet diagnostics, treatment and public awareness are largely inadequate. Please Help To support Lyme Disease
Do what you can, because every thought counts. Thanks for Listening! Presentation Made By:
