The epidemiology of Lyme disease
Causes of the disease Lyme disease is caused by the spirochete bacteria Borrelia burgdorferi.
History of the disease
In the 1970’s children living in Lyme, Connecticut and two other neighboring towns started to show rheumatoid arthritis. Because of how strange this was researchers started to look for a causing agent looking at everything including germs, and found a pattern looking at where these kids lived. Considering the children’s initial symptoms started typically during the summer which is when ticks are their peak they turned their eyes to deer ticks.
Some of the children treated reported having been bit by a tick before the rash develop. By the mid 1970’s researchers had named this new disease Lyme disease and began describing the signs and symptoms in order to help physicians diagnosing patients. Still, it was not until 1981 when a researcher from the National Institute of Allergy and Infectious Disease (NIAID) at the Rocky

It is documented the tick bite must be in place for at least 36-48 hours in order for the bacteria to be transmitted to its host. Deer ticks go through four stages of life, and in between stages they must a blood feeding. During the first two stages, eggs and larvae, deer ticks feed of mice and other rodents, which unfortunately are prime reservoirs for the Lyme disease bacteria. Later on, during the next two stages, nymphs and adults, they mostly feed on white-tailed deer, but this is when they become a danger to humans. They can’t fly or jump so they just basically wait on the grassy areas for a new host, so if you happen to walk by at the right time, especially with exposed skin, you could become it. The exposed skin makes it easier for the ticks to attach. Pets like cats and dogs have also been known to carry the ticks into your
White-tailed deer, along with the rest of the Cervidae family, are facing a possible epidemic. Although the disease has not spread over the entire range CWD is efficiently transmitted between individuals. CWD is to the best of our knowledge 100% fetal and incubation can take a few years allowing for many possible transmissions. There also at this time is no form of vaccine or treatment for infected cervids. Despite efforts being put forth to control CWD, being a free-range family of animals proves control to be extremely difficult.
Lyme borreliosis is caused from the bacterial spirochete B. burgdorferi (“A History of Lyme”). It is a zoonotic disease carried by vectors and transmitted biologically (Tortora, Funke, and Case, 410). Lyme borreliosis has diverse symptoms, from a rash to neurological problems (Tortora, Funke, and Case, 651). The recommended treatment is antibiotics, but even with treatment some people still experience post treatment lyme disease syndrome (CDC). It is an Emerging Infectious Disease and is endemic in areas of the United States (CDC).

...who have hunted in CWD endemic areas to have their deer or elk tested before they consume the meat in order to prevent ingestion of contaminated meat (Chronic Wasting Disease Alliance).
In addition, Valley Fever has not received sufficient funding for research. Many milder cases go undiagnosed, which may mean that the reported cases are just the tip of the iceberg. The increase could be because of: • More people exposed to the fungus because of increased travel or relocation to the southwestern United States • Changes in the way cases of valley fever are being detected and reported to public health officials, or • Changes in factors such as temperature and rainfall, which can affect the growth of the fungus in the environment and how much of it is circulating in the air. There is no vaccine to protect against it and, in the most severe cases, no cure. The population of Phoenix has grown by ten per cent in the past decade, and newcomers have no acquired immunity.

Several tests may be performed on patients to determine the cause of lymphatic damage and elephantiasis. A definitive diagnosis of lymphatic filariasis is done through the identification of the microfilariae in blood. Samples of blood are taken at night. Other test used for diagnosis is immunodiagnostic test; it can identify the cause of the symptoms based on the detection of antigens of Wuchereria bancrofti. This test is highly specific and sensitive, blood samples do not have to be taken at night (Seppa
Lyme disease is one of the seven most common diseases reported in the United States to the CDC annually (www.cdc.gov). The rates have gone from 10,000 cases in 1992 to over 30,000 cases in 2009. 95% of these cases were found in the northeast and Midwest regions of the United States (Committee on Lyme Disease, 2011) . More cases happen in this area of the country due to the close proximity of deer to population. The bite itself isn’t the problem, rather the pathogen being spread in mammals from the bite. Lyme disease occurs when a tick penetrates the skin of mammals and the spirochete Borrelia burgdorferi enters. Borrelia burgdorferi is carried by ticks named the Ixodes dammini, which is the main vector for Lyme disease. These may also be known as I. scapularis, and may be found on deer (Schilling-McCann, 2010). ¬¬¬In addition to Lyme Disease, ticks may also carry Rocky Mountain Spotted Fever or Tularemia (Smeltzer et al, 2010).
You wouldn’t think the carrier of this disease would come from a little mosquito bite but it does.
Through the rise of technological advances in medicine, the vaccine has changed the world for the greater good of the human race. Making a great triumph and virtually eliminating an array of life-threatening diseases, from smallpox to diphtheria, thus adding approximately thirty years to many humans’ life spans. Although, a new complication has arisen, possibly linking neurological digression with this rise of new vaccines. Such a digression has forced parents to exempt their children from receiving vaccinations and brought forth mental anguish affecting the minds of many.
A disease is transmitted in one way or the other. Lyme disease is transmitted through a vector. The vector of the disease is an infected deer tick. The deer tick has to bite a person to spread the disease. When a deer tick bites a person (sucks blood), the Borrelia burgdoferi bacteria is transmitted into the persons body.

As you exit the bus, another passenger next to you starts to cough, and then you hold the handrail as you exit the bus. Since you’re late getting home, you take a shortcut through a field to get home quicker. These three simple acts just exposed you to bacteria, viruses, and insects that could cause illness or even death. Infectious diseases, also known as communicable disease, are spread by germs. Germs are living things that are found in the air, in the soil, and in water. You can be exposed to germs in many ways, including touching, eating, drinking or breathing something that contains a germ. Animal and insect bites can also spread germs.1
Almost 8 million people are infected with hookworm (Freary et al), in severe cases it can result in death. On the contrary, epidemiological evidence suggests the hookworm may help with allergies and asthma. Two different scientific tests were performed to see if hookworms could help with symptoms of allergies and asthma. The first study was done to determine if hookworm infection would help airway responsiveness in a person who has allergies. The second study tested “to see the effects of experimental hookworm infection in asthma” (Freary et al). In comparison both the studies were trying to use hookworms as a treatment for issues with people’s immune systems. Contrastingly, the first study (based on allergies) had to be conducted first in order for the second study (asthma) to be conducted due to safety precautions. The allergy study also had to be conducted first to see if anything would even happen. Before these studies were performed there were two similar previously done studies. One of the studies tested hookworm intensity with normal people. It was important to have these studies as information for the two being analyzed for information on safety and the effects.
The symptoms were blisters of the skins with puss and bleeding with high fever. The government was very aware and thought they had a vaccine but the micro-organism morphed into another pathogen that was airborn and the previous vaccine was no
