1. Typhus
Typhus is one of several similar diseases caused by Rickettsiae. The name comes from Greek meaning typhos smoky or hazy, describing the state of mind of those affected with typhus. A reliable picture of the disease first appeared during the Spanish siege of Moorish Granada in 1489. These include descriptions of fever and red spots on arms, back and chest, advancing to the delirium, gangrenous sores, and the smell of rotting flesh. During the siege, the Spaniards lost 3,000 men to enemy action but an additional 17,000 died of typhus. Epidemics occurred throughout Europe from the 16th to the 19th century, and occurred during the English Civil War, the Thirty Years' War and the Napoleonic Wars. In the Thirty Years' War, 8 million Germans eliminated by plague and typhoid fever. During Napoleon's retreat from Moscow in 1812, more French soldiers died of typhus than were killed by the Russians.
2. Ebola
Named after the Ebola hemorrhagic fever Ebola River, where the first recognized outbreak of fever occurred. The virus is characterized by long filaments, and has a shape similar to the Marburg virus, also in the family Filoviridae, and have similar symptoms. It remains largely unclear until 1989 with the outbreak in Reston, Virginia. This virus has been confirmed to be transmitted through body fluids, however, transmission through oral exposure and through conjunctiva exposure is possible. In the early stages, Ebola may not be very contagious. Contact with someone at an early stage may not transmit the disease. As the illness progresses, bodily fluids from diarrhea, vomiting, and bleeding represent an extreme biohazard. Due to lack of proper equipment and hygienic practices, large-scale epidemics occur mostly in poor, remote areas without modern hospitals or well-educated medical staff.
3. Malaria
Some of the symptoms of malaria are anemia, fever, chills, and even coma or death. The disease is usually spread when people are bitten by an Anopheles mosquito, infected from other humans. Every year, there are approximately 400 million cases of malaria, killing millions of people. This disease is one of the most common infectious diseases, and serious problems. Currently, no vaccine has been made a big impact, but many are being created.
4. Cholera
In the most severe form of cholera is very fatal. If not treated within three hours, people who are infected will die. Symptoms of diarrhea, shock, bleeding, leg cramps, vomiting, and dry skin. The first cholera outbreak in Bengal, and from there it spread to India, China, Indonesia, and the Caspian Sea. When the pandemic finally ended in 1826, there were more than 15 million deaths in India alone. Oral rehydration therapy and antibiotics to treat cholera.
5. Smallpox
Smallpox is believed to begin to infect humans in 10,000 BC In England in the 18th century the disease has killed about 400,000 people each year and is responsible for most of the blindness. Other signs include vomiting, back ache, fever, and headache. The earliest evidence of smallpox in ancient Egyptian mummies. It is estimated that Egyptian merchants brought the disease to India, where it remains endemic during the past 2000 years. After successful vaccination campaigns throughout the 19th and 20th, the WHO certified the eradication of smallpox in December 1979. To this day, smallpox is the only human infectious disease has been completely eradicated.
6. Spanish Flu
The 1918 flu pandemic (commonly referred to as the Spanish flu) was an influenza pandemic that spread to nearly every part of the world. This is caused by influenza incredible evil and deadly strain of virus A subtype H1N1. Historical and epidemiological data are inadequate to identify the geographic origin of the virus. Most of the victims were healthy young adults, in contrast to most influenza outbreaks which predominantly affect juvenile patients, elderly, or weakened. pandemic lasted from March 1918 to June 1920, spreading even to the Arctic and remote Pacific islands. It is estimated that anywhere from 20 to 100 million people were killed across the world, or the approximate equivalent of one third of the population of Europe. Interestingly, the Spanish flu came from the same subtype (influenza A virus subtype H1N1) virus as swine flu.
7. Yellow Fever
Yellow fever symptoms are things such as fever, chills, slow heartbeat, nausea, vomiting, and constipation. WHO estimates that the disease causes about 30,000 deaths every year, when left unvaccinated. A well-known outbreak of yellow fever in Philadelphia, Pennsylvania in 1793. This disease has killed as many as 10,000 people in Philadelphia alone. Most of the population fled the city, including the president. But, the mayor lives and the life and order were soon restored.
