This disease is also known as American trypanosomiasis. It is a tropical parasitic disease caused by the protist Trypanosoma cruzi. It is spread mostly by insects known as Triatominae, or "kissing bugs". The signs and symptoms: Early stage, symptoms are typically either not present or mild, and may include fever, swollen lymph nodes, headaches, or local swelling at the site of the bite. After 8-12 weeks, individuals enter the chronic phase of disease and in 60-70% it never produces further symptoms. The other 30 to 40% of people develop further symptoms 10 to 30 years after the initial infection, including enlargement of the ventricles of the heart in 20 to 30%, leading to heart failure.

Caused by a virus transmitted by the Aedes aegypti mosquito. Signs and symptoms: sudden onset fever, headache (typically located behind the eyes), muscle and joint pains and rash. It is also known as breakbone fever because of the muscle and joint pains. Occurs in three phases febrile, critical and recovery.

This disease was first identified in 1976, when two simultaneous outbreaks occurred in the Democratic Republic of the Congo and was named after a river near one of the first outbreaks. It is a viral hemorrhagic fever of humans and other primates. Signs and symptoms typically start between two days and three weeks after contracting the virus and include fever, sore throat, muscular pain, and headaches. Followed by vomiting, diarrhea and rash, along with decreased function of the liver and kidneys. At this time, some people begin to bleed both internally and externally. The disease has a high risk of death, killing between 25 and 90 percent of those infected, with an average of about 50 percent. In 2016 there was largest outbreak in history of this disease in West Africa.

The clinical name for this disease is lymphatic filariasis and is caused by a parasitic roundworm (Nematode). 90% of the cases are caused by the roundworm parasite Wuchereria bancrofti, which is transmitted by the bite of a mosquito infected with the larva stage. The adult stage lives in the lymphatic system and disrupts the flow of lymph and affects the functioning of the immune system. Obstruction of the lymphatic vessels leads to swelling in the lower torso, typically in the legs and genitals.

Causative agent: Acute: Staphylococcus aureus or Streptococcus pneumoniae. Subacute: S. epidermidis. Acute symptoms: Abrupt onset, Pneumonia infection present, valve destruction/abscess formation in heart muscle. Subacute symptoms: Heart murmurs, fatigue and fever. Slowly lose energy over a period of weeks or months. Abrupt development of stroke may occur.

This disease is caused by the bacteria Rickettsia prowazekii, which lives in the alimentary tract of the body louse (Pediculus corporis). This disease is transmitted to humans when the louse bites to engage in a blood meal. The louse defecates as it eats; when the host scratches the site, the lice are crushed, and the Rickettsia-laden excrement is inoculated into the bite wound. This disease is responsible for large epidemics in populations with poor sanitary and overcrowded conditions. The disease can be severe with a mortality of up to 60% without antibiotic treatment.

Caused by Gram-negative bacteria such as E. coli and Pseudomonas aeruginosa. Symptoms are cause by the release of the endotoxin LPS when bacteria break down.

Caused by the nematode Dirofilaria immitis, which is transmitted by mosquitoes primarily to domestic dogs, wild wolves and foxes, and raccoons. Adult D. immitis can cause pulmonary blockage producing the following symptoms: Cough, exhaustion upon exercise, fainting, coughing up blood, and sever weight loss

An RNA virus with the following symptoms causes this disease: Loss of appetite, nausea, fatigue, joint pain, jaundice, and dark urine. The virus is transmitted person to person through body fluids and enters the bloodstream and affects the liver. No medical treatments once contacted, but there is a vaccine available for prevention.

This is a vial infection of the liver caused by an RNA virus that is spread through the blood or body fluids of an infected individual by sharing needles, being stuck with an infected needle, or through sexual contact. Symptoms include stomach pain, loss of appetite, nausea, fatigue, and jaundice. In January of 2016 a once-daily pill called Zepatier was approved by the FDA and has been shown to cure the disease in almost 100% of those treated.

This is a viral illness common in West Africa transmitted by the multimammate rat Mastomys natalensis. The virus is transmitted by direct contact with food or household items contaminated with rat droppings and/or urine. Signs and symptoms: Occurs in 1-3 weeks after contacting virus. Mild symptoms include slight fever, malaise, weakness and headache. In sever cases hemorrhaging in the gums, and nose can occur.

Caused by protozoans in the genus Plasmodium, which are transmitted by the bite of infected mosquito. Symptoms: "flu-like" includes fever, headache and pain in the joints and muscles. Symptom pattern changes after 2 to 3 weeks.

Caused by the Epstein-Barr virus, which is a double stranded DNA virus that belongs to herpes virus family. Also called the kissing disease. Symptoms include: Fever, sore throat covered with pus, fatigue, enlarged lymph nodes and spleen. Most cases fever and sore throat disappear within 2 weeks.

Caused by the bacteria Yersinia pestis, which is carried by infected black rats and is transmitted to humans by the bite of fleas that have bitten infected black rats. Symptoms develop abruptly 1 - 6 days post infection. Disease is characterized by large tender lymph nodes called buboes. Other symptoms include, high fever, shock, delirium, and patchy bleeding under the skin.

This disease is caused by an infection with freshwater parasitic worms found in certain tropical and subtropical countries. It is an acute and chronic parasitic disease caused by blood flukes (flatworms) such as S. mansoni and S. japonicum . Signs and symptoms include rash, itchy skin, fever, chills, cough, headache, belly pain, joint pain, and muscle aches.

The disease was first described during World War I. It is caused by the bacteria Bartonella quintana and is transmitted by the vector Pediculus humanus var corporis (body louse).

Signs and symptoms include fever, chills and profuse sweating, frontal or retro-orbital headache, often associated with a stiff neck and photophobia, neuropsychiatric symptoms, such as weakness, depression, restlessness, and insomnia, Conjunctivitis, difficulty or labored breathing, abdominal pain, often associated with anorexia, nausea, vomiting, weight loss, diarrhea, and constipation, bone pain, particularly involving the shins.

Is a bacterial disease caused by Francisella tularensis, a non-motile, aerobic, Gram negative, rod shaped bacteria. Symptoms are characterized by development of skin ulcerations and enlargement of regional lymph nodes. Other symptoms include fever, chills, and body aches. The disease is all so known as rabbit fever or deer fly fever.

Caused by four varieties of bacteria in the genus Brucella, which are transmitted to human by contact with domesticated infected animals such as dogs, cattle, goats, and pigs. Occurs in workers in the meatpacking industry and a major problem in animals used for food. Can be contacted by ingesting raw milk and unpasteurized dairy products. Symptoms include: Headache, weakness, depression, weight loss, fatigue, and liver dysfunction.

An enveloped single stranded RNA Arbovirus belonging to the Flavivirus family causes this disease. The virus multiplies in the Aedes mosquito, which transmits the virus to humans. Symptoms can range from mild to severe. Common form may be only fever and slight headache lasting a day or two. Severe disease characterized by high fever, nausea, nose bleeds, bleeding into the skin, and "black vomit" from GI bleeding and jaundice.
