Smallpox Moosa Mohammed Health Science Technology 3/4/2016 Smallpox Smallpox is a viral and contagious infection that is caused by the Variola Virus. Smallpox is a disease that arose approximately 10,000 years ago in Africa and Southern Asia that spread quickly through the air and eventually spread throughout the whole world. Smallpox is a fatal and dangerous disease that has no cure but does have a vaccination to prevent it. However the vaccination does comes with a few dangerous side effects making this infection something no one wants to have. In addition Smallpox can spread very easily making people more vulnerable to it.
The Hot Zone, an extraordinary novel with chilling events, was significantly amusing in copious ways. The fast paced spreading of infections, the grueling deaths, and the race against time to find a cure; stopping the viruses in their tracks. These main concepts are the greatest points that contributed to the storyline. These factors that Richard Preston stated specifically, came together to create a thrilling novel. In the novel, The Hot Zone, many new superstitions become significant due to the fear of epidemics.
Sputum contains a lot of bacteria, viruses, fungi and other pathogens. Respiratory infectious diseases, like influenza, tuberculosis, bronchitis, pneumonia, measles, pertussis, diphtheria and other pathogens, are spread through the sputum, very dangerous. Spitting there are many hazards, not only can cause health problems, in infectious disease multiple times, phlegm is a highly damaging route of transmission, inadvertently freely spit sputum are likely to have increased 10 people infected with the virus. First of all, spitting could lead to spread bacteria, into the air will harm to people. In our usual life, no spitting everywhere slogan, the reason is spitting is an extremely uncivilized unsanitary, spitting will make sputum bacteria spread easily, especially in public places, crowded place will make the spread of the virus.
The central idea of Richard Preston’s The Hot Zone is that the outbreaks of many deadly hot agents are due to the oversight of humans. Preston conveys his message through detailed descriptions of simple mistakes that characters make. One instance of human oversight that he wrote about was the usage of dirty needles in the hospitals of Sudan, leading to a massive outbreak of Ebola Sudan. The virus “hit the hospital like a bomb” and “transformed the hospital at Maridi into a morgue” all because “the medical staff had been giving patients injections with dirty needles” (74). Due to the blunder of the hospital staff, Ebola Sudan was spread much quicker and killed much more than it would’ve if they had used sterile needles.
Pandemics will be the downfall of the human race. Avian flu can become this pandemic. Avian flu is a bird flu, but has been known to make the cross-species jump to humans, pigs, and even whales. The H5N1 virus, a strain of an avian influenza, has been terrorizing the world for several years. Symptoms affect the infected host very quickly and negatively, sometimes causing death in a day.
Press Centre Fact Sheet by UNICEF Questions and Answers on Polio in general Q What is poliomyelitis disease? Poliomyelitis (polio) is a highly infectious disease caused by a virus that invades the nervous system and can cause total paralysis in a matter of hours. Approximately one in 200 infections leads to irreversible paralysis, usually in the legs. Among those paralysed, five to ten per cent die when their breathing muscles become immobilized. Poliomyelitis mainly affects children under 5 years of age.
From Napoleon’s defensive action at Walcheren, to the Union Army’s attempts to take control of the Mississippi River at Corinth and Vicksburg, to the Dreadful numbers of malaria casualties suffered by U.S. Marines on Goudal Canal during the World War II and more recently in Vietnam, numerous people on the world died because of a catastrophic disease, malaria. Although the disease has now been given medical research by a lot of scientist from a lot of country thus a number of anti-malaria drugs have been created, it is still a harmful disease and still need more research to completely wipe it out. The effect of malaria cannot be showed through simple numerical data, so here we just talk about it effect in a specific historical period, the Vietnam War.
Mass hysteria is a condition affecting a group of persons, characterized by excitement or anxiety, irrational behavior or beliefs, or inexplicable symptoms of illness. Since the beginning of time everyone has dealt with mass hysteria. One mass hysteria that connects to this story is the hysteria about the Ebola virus infecting everyone. The Ebola virus by definition is a usually fatal disease, a type of hemorrhagic fever, caused by the Ebola virus and marked by high fever, severe gastrointestinal distress, and bleeding. We all know how rare the chances are of actually getting infected yet no one cares.
Category 4 hurricanes start to cause catastrophic damage. They cause brutal flooding and this hurricane type begins to kill many people. Category 5 hurricanes are major storms that cause fatal damage and usually have a death toll of around one-hundred people. They have wind speeds of 157 mph and
Acquired immune deficiency syndrome (AIDS) is the world’s most dreaded disease caused by the human immunodeficiency virus (HIV). Precisely, the viral infection destroys the immune system of the patient by way of eliminating the CD4+ lymphocytes (Mandal, 2012). With decreased immunity, the body becomes vulnerable to a wide range of infections otherwise known as opportunistic infections. These could be viral, bacterial, or fungal infections as well as tumors and other conditions adverse to a person’s health (Mandal, 2012). Ideally, the pathology of AIDS involves several key states namely seroconversion illness, asymptomatic infection, persistent generalized lymphadenopathy, symptomatic infection, and eventually AIDS (Mandal, 2012).
Ebola Viruses There are many different ways to pass away, some harsher than others. In “The Hot Zone” By Richard Preston, there are a few different viruses explained to be deadly to not only humans, but other species as well. The hot zone is an area on earth that contains lethal, infectious organisms. Marburg virus, Ebola Zaire, and Sudan virus all contribute to making the hot zone so pernicious. One of the viruses mentioned in “The Hot Zone” that significantly contributes to the Ebola virus disease (EVD) is the Marburg virus disease (MARV) is rare but a severe hemorrhagic fever.
