Hemorrhagic fevers are multiple viral illnesses in a group. The group is responsible for illnesses such as Ebola,marburg, lassa fever and yellow fever viruses. Also called VHF’s can be fatal. The VHF’s may be different illnesses, but these viruses have many common symptoms that are very crucial. The symptoms include damage to blood vessels and damage to organs. When the body’s organs are damaged the body loses its ability to regulate itself, which in time can cause it to shit down entirely. The hemorrhagic fever viruses have all occurred in different places and at different times. The first case of the most well known illness of the group (Ebola) or classified as Zaire ebolavirus, occured in 1976 when it broke out in two separate people near the exact same time. One of the patients broke  out into ebola in South Sudan, and one in Democratic Republic of the Congo. Once the two subjects came down with the illness, the outbreak continued in a village close to the Ebola River, which is why the river is called that today. After the outbreak in 2015 it is suspected that the disease is caused by “nonhuman primates” such as different breeds of monkey. A certain cause other than infection has not been proved. Ebola spreads through human to human contact where blood or skin is transmitted through the two subjects. Through the viruses mutations in 2015 it was suspected it would become airborne but did not become so. When a patient comes down with ebola they are likely to experience body aches, fever, it damages the organs and immune system of the body and causes blood clotting cells to drop, which causes profuse bleeding from the pores of the body. The cures to this disease are not widely known. In the most recent outbreak it was found that the antibodies of a survivor cured the patients, but due to limited supply of another human antibodies, there is no sufficient cure. The marburg virus or genus marburgvirus was first discovered in 1967 when a German lab worker came down with hemorrhagic fever after handling infected tissue. The first outbreak was in 1975 in South Africa in a person who had been traveling from Zimbabwe. Throughout the 1970’s and into the 80’s several cases occurred sporadically. The natural origins of this disease are still unknown other than fruit bats are expected to be a natural host of the virus. After a human comes in contact with one of the bats the disease is then spread through human to human contact. The first symptom of this disease like many is fever, followed by chills, headache, and myalgia, a maculopapular rash, most prominent on the trunk (chest, back, stomach), Nausea, vomiting, chest pain, a sore throat, abdominal pain, and diarrhea, jaundice, inflammation of the pancreas, severe weight loss, delirium, shock, liver failure, massive hemorrhaging, and multi-organ dysfunction. The cure to this disease is unknown like Ebola and has a very high fatality rate. Lassa fever also known as Lassa Hemorrhagic fever was first found in West Africa in 1969 when two missionary nurses lives were claimed in the country of Nigeria. The virus comes from the rodent family of rat called the African rat. After exposure to the rat human to human contact can also spread the disease, though the disease is not as contagious as ebola or marburg. The symptoms begin with flu-like symptoms and turn into more complicated symptoms such as tremors, seizures and damage to the liver. Though the disease only has a fatality rate of 1% and 15% in severe cases, in pregnancy there is a 95% chance the baby will be stillborn or killed. The cure to lassa fever is an antiviral medication called ribavirin, this cure is only effective if administered during the first 6 days of infection. The person who discovered the cure and where is unknown. Yellow Fever classified as Flavivirus febricis is a viral infection originally found in East or Central Africa. This disease was first mentioned in Africa in 1744. The yellow fever virus is spread through a type of mosquito bite (Aedes aegypti). After a bite from the mosquito the virus is then spread through human blood and semen. In cases of mild infection the virus only lasts three to four days after an incubation period of up to six. With mild infection the symptoms are known as fever, chills, loss of appetite, fatigue, vomiting and nausea. 15% of cases are severe cases and the symptoms are known to be damage to the liver and kidney, vomit with blood which is why the spanish name for the disease translates to “Black vomit”, bleeding in the mouth and eyes and damage to gastrointestinal tract. The cure to this disease is unknown but can be treated and there is a vaccination. The treatment focuses on the fever and muscle pain by keeping the patient hydrated. Vaccination of this disease is advised for any child over the age of 9 and anyone who will be traveling to african or latin american countries, often times there is a travel ban unless you are vaccinated, the vaccine must be repeated every 10 years to those who choose to travel to high risk areas.
