A person can acquire Lyme disease by the bite of an infected tick. This disease is transmitted by deer ticks or black-legged ticks. Ticks are tiny in size and as their bite is painless, people might not even realize that they have been bitten. Once an infected tick attaches itself to the skin, it is able to transmit the bacteria. This bacteria eventually ends up in the bloodstream. The duration of attachment necessary to transfer

Heartworm disease is a serious and potentially deadly disease that ultimately affects animals all around the world. A heartworm is a blood-borne parasite called Dirofilaria immitis that resides in the heart and surrounding large blood vessels of infected animals. The presence of heartworms in the body often leads to severe lung disease, heart failure, and damage to other organs. Heartworm disease affects a variety of species including pets, wildlife, and although rare, humans.

The disease was caused by rats and rat fleas but, also from human to human by breathing the same air. Scientists know that the bacillus travels from person to person, through

Woman and men had swelling in the groin or under armpit, it was the size of an egg. This infected area would have pus or blood is oozing out. Some of the other effects are vomiting, diarrhea, aches in the body, or having a fever. After the symptoms change black or purple spots are found on the body. Sooner or later the person with the disease will die.

In the early stages of heartworm, little to no symptoms will occur. Symptoms in most animals that will be noticed could be a mild persistent cough. The animal will have a decreased appetite. They could have a bulging chest due to excess fluid. They will experience weight loss and have difficulty breathing. They will have a reluctance to exercise and be fatigue. They could have an allergic reaction to the offspring of the worms. The worm(s) can cause blockage in the blood flow of the heart and cause the animal to collapse, this is mostly common to be the first sign to appear in cats. It is difficult to diagnose a cat for heartworm because they will experience the same symptoms that are used to diagnose other diseases in felines. This could include weight loss, fatigue, and difficulty breathing. Also, they could experience gagging and vomiting. Other signs that have been documented in heartworm are nose bleeds, secondary pneumonia, increased blood pressure, and excessive sleeping. It is rare that the worm(s) could get lost and end up in the brain or eyes and cause seizures, blindness, and lameness. Given the symptoms and clinical signs, we can move on to how heartworm is

Where you live in the U.S. has a significant impact on your risk of getting Lyme disease. Most cases occur in the Northeastern U.S. or the Midwest. In fact, in 2105, 95 percent of confirmed Lyme disease cases in the U.S. occurred in just 14 states. If you live in one of the following states, you are at increased risk of exposure:

Blastocystis hominis (B hominis) is a common parasitic organism found throughout the world. An infection with B hominis is called blastocystosis. The parasite lives in your large intestine and can be found in stool. It can remain in the body for weeks, months, or years. It is not known whether the parasite B hominis causes any symptoms in humans or if the associated symptoms may be caused by infection with other parasitic organisms, bacteria, or viruses. Often, B hominis is found along with other organisms that are more likely to be the cause of your symptoms.

Most parasitic diseases can not be contracted in the United States but when traveling, you can catch it. Luckily, you can take some precautions to avoid contracting them. There are some diseases contracted by consuming contaminated water and food. Some of the preventative measures that should be taken to avoid this is keeping away from drinking the water, swimming only in designated swimming areas, not swimming in freshwater and avoiding swallowing water when swimming, steer clear from cooked food from street vendors, raw vegetables, and unpasteurized dairy foods such as milk or cheese. You should also get specific vaccinations before entering different countries like diphtheria, tetanus, pertussis, Influenza, Measles, Polio, Hepatitis A, Hepatitis

The Bubonic Plague seems now to be a problem of the past, but as time goes on, the science world discovers more about the inner workings of the illness. The basics of the plague, however, have been known for a while. As we know it, the Bubonic Plague is no longer an issue in everyday life, but, surprisingly, it is still affecting people around the world. While cases of this can be found in the more rural parts of the United States, it is primarily an issue in third-world countries, where rats and fleas are more prominent, and there is a lower state of cleanliness (Sutyak, Katia. n.d.).

However, with the work of modern medicine, antibiotics such as streptomycin, gentamicin and doxycycline have been developed to treat the plague. However, if treatment is not received within 24 hours of contracting symptoms, death can result. (NLM, 2013) With the development of antibiotics to treat the plague, treatment reduces your chances of mortality to 15%, but without treatment the prognosis for a person infected with the bubonic plague has a 50% to 90% death rate. Furthermore, if left untreated, the bubonic plague can either multiply in the bloodstream, causing septicaemic plague, or progress to the lungs, causing pneumonic plague, both of which have a higher mortality rate, even with antibiotic treatment. However, several preventive measures can be taken to limit your risk of contracting the disease, active immunization with a vaccine of killed bacteria offers protection against the bubonic plague. This particular vaccine is administered in three doses, with the first two 1 – 3 months apart, and dose three administered 5 – 6 months after the second vaccine. However, booster shots are required every 6 months in high risk areas, such as western USA. (UCLA,

How the disease was transmitted was further looked on by Nelson (1995). According to the said author, the disease was transmitted primarily by fleas and rats. The stomachs of the fleas were infected with bacteria known Y. Pestis. Nelson held that “the bacteria would block the "throat" of infected fleas so that no blood could reach their stomachs, and they grew ravenous since they were starving to death” (1995, par. 14). The bacteria would then attempt to suck up blood from their victims, only to disgorge it back into their preys' bloodstreams (Nelson, 1995). Now, however, the victims' blood was mixed with Y. Pestis. Fleas infected rats in this fashion, and the rats spread the disease to other rats and fleas before dying (Nelson, 1995). Without rodent hosts, the fleas then migrated to the bodies of humans and infected them in the same fashion as they had the rats .

The whipworm is a parasitic worm that acquired it name due to its shape of a whip. Whipworms cause infections called trichuriasis. Trichuriasis is a type of infection that occurs in the large intestines. The infection occurs most commonly in children and develops after ingestion of water or dirt.that is contaminated with feces. Soil can become contaminated with whipworm eggs through contaminated feces that are used in fertilizers. The contaminated fertilizer can then infect lawns or lawns can become infected when infected animals of humans relieve themselves outside. Contact with the feces can infect anyone who is exposed to it. Symptoms of a whipworm infection include, nausea, vomiting, abdominal pain,headaches, unexpected weight loss, painful bowel movements, incontinence, and bloody diarrhea.

When traveling to and from exotic locations, vacationers are warned about drinking untreated water, swimming in freshwater lakes and streams, and against eating certain foods. The risks for contracting a parasitic disease while abroad are pretty well defined and as a traveler you are made aware. Less known are the risks here at home. It is a fact however that parasitic diseases in the US are on the rise. According to Dr. Oz “approximately 1 in 3 Americans is infected with an intestinal parasite at any given time.” Specific statistic are not available because most Americans who are infected may be unaware. Often the symptoms of neglected parasitic infections are troublesome, however, vague. Therefore treatment is not immediately sought and even

Apart from food transmission the virus is most commonly contracted via person-to-person contact. Several other ways of transmission include touching surfaces or objects that are contaminated with the virus and then proceeding to

     Transmission of the parasite can occur in several different ways. Direct transmission can occur by handling infected animal or human feces. One quarter of reported direct transmission infections occurred by direct contact with feces, while the rest were reported to have happened by person to person contact (Donnelly & Stentiford, 1997).
