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.
It enters the body through the lungs and is carried to the internal organs. Then, the skin is infected and boils and rashes will appear all over. Smallpox is spread through contact between people and saliva when talking, coughing or sneezing. It can also be spread rapidly when the boils on the skin burst, leading to the smallpox DNA going everywhere.The highly infectious disease ravaged and plagued across the globe, decimating a large number of the population. In the 18th century, it had an astonishing mortality rate of 90% in the United States.
The symptoms associated with an infection caused by C.diff are the result of gastroenteritis which is “a very common health problem worldwide that causes diarrhea and/or vomiting as a result of INFLAMMATION of the mucous membranes of the stomach and intestinal tract. It affects mainly the small bowel and can be caused by either viral or bacterial INFECTION” (Ignatavicius and Workman, 2016, p.1127). One of the largest barriers to treatment of a C.diff infection is the resistance to antibiotics. The CDC (2016) says “C.difficile caused almost half a million infections among patients in the United States in a single year. An estimated 15,000 deaths are directly attributable to C.difficile infections” (clostridium difficile section, para.
There's five different mutations of the Ebola virus: Ebola Zaire, Ebola Sudan, Taï Forest Ebola, Ebola Reston, and Bundibugyo Virus (“Ebola” 1). With so many different symptoms, which require a different attack. The Ebola virus is complex, making it even harder to fight. Ebola has intense symptoms, High fatality rates and no cure. “In humans, certain Ebola viruses can cause fatality in 50 to 90 percent of cases” (“Ebola” 1).
WHO reports that there are about 1.3 million to 4 million cases of cholera reported around the world annually. The disease is also responsible for death of about 21,000 to 143,000 people per year. (http://www.who.int/mediacentre/factsheets/fs107/en/) Cholera was once a pandemic disease, causing death of millions of people. Today, cholera exists in regions that are developing but is easily curable and is considered an endemic disease. The
The problem is quite serious because several of the emerging diseases such as the Powassan virus have been found to be devastating. According to Knapp and Rice (2015), over 10 percent of people infected with the Powassan virus are dying due to encephalitis and meningitis caused by the disease (p. 9). Tick-borne diseases have consequential effects and should not be taken lightly. If this problem is not dealt with then tick-borne diseases could be the number one cause of death in the United
There are some strains of influenza that escape the vaccination every year. Viruses are highly susceptible to mutations during replication, so these strains likely experience a mutation in either the hemagglutinin or neuraminidase at some point. This mutation alters the shape of these glycoproteins, causing the antibodies in the victim’s immune system to not be able to bind to the virus. This is usually where the seasonal flu virus comes from each year. New strains of influenza mutate all the time, causing all organisms vulnerable to become sick and start the process of developing new antibodies all over again.
A single person with, “pertussis can infect up to 12 to 15 other people” (Pertussis F.A.Q). Pertussis(Whooping Cough) is an easily transmitted virus, its vaccine has been developed, and Pertussis seems to be a near to nothing problem in the future. To begin with pertussis, commonly known as whooping cough is, “a very contagious disease caused by a type of bacteria called Bordetella Pertussis” (Causes and Transmissions). It’s a common disease in the United States, it has reported peaks every 3 to 5 years and has frequent outbreaks. Pertussis easily passes from person to person due to the fact that it is capable of becoming airborne.
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.
The main diseases that run through Costa Rica include Malaria, Dengue, Fever, Chagas Disease, Leptospirosis, Zika and Yellow Fever. According to Pan American Health Organization, in 2006-2010, 84,443 cases of Dengue disease were reported, of which 471 were serious. Costa Rica is considered a high-risk area for Malaria, which encompasses approximately 70% of the home population. Leptospirosis has the highest morbidity of any disease in which has caused a total of 46 deaths from 2006-2010, conferring from the Pan Health Organization. Costa Rica health officials have been in tight guard and have cautioned future travelers informing them that cases of the Zika virus have been confirmed.
