Righting the wrongs of science False findings must be acknowledged and 'corrected' to keep science credible Stephen Ornes Sep 11, — 7: Instead, it gets flagged as unreliable.
A pandemic is an epidemic of infectious disease that spreads through populations across a large region; for instance a continent, or even worldwide. Killed more than million people worldwide in the 20th century alone, and most of the native inhabitants of the Americas Smallpox Smallpox also known by the Latin names Variola or Variola vera is a contagious disease unique to humans.
Smallpox is caused by either of two virus variants named Variola major and Variola minor. The deadlier form, V. Long-term side-effects for survivors include the characteristic skin scars. Occasional side effects include blindness due to corneal ulcerations and infertility in male survivors.
Smallpox killed an estimated 60 million Europeans, including five reigning European monarchs, in the 18th century alone. As for the Americas, after the first contacts with Europeans and Africans, some believe that the death of 90 to 95 percent of the native population of the New World was caused by Old World diseases.
It is suspected that smallpox was the chief culprit and responsible for killing nearly all of the native inhabitants of the Americas.
In the fighting, a Spanish soldier carrying smallpox died. When Cortes returned to the capital, smallpox had devastated the Aztec population.
Smallpox was responsible for an estimated million deaths in the 20th century. As recently asthe World Health Organization WHO estimated that 15 million people contracted the disease and that two million died in that year.
After successful vaccination campaigns throughout the 19th and 20th centuries, the WHO certified the eradication of smallpox in To this day, smallpox is the only human infectious disease to have been completely eradicated from nature.
Spanish Flu — Killed 50 to million people worldwide in less than 2 years Spanish Flu In andthe Spanish Flu pandemic killed more people than Hitler, nuclear weapons and all the terrorists of history combined.
A pandemic is an epidemic that breaks out on a global scale. Spanish influenza was a more severe version of your typical flu, with the usual sore throat, headaches and fever. However, in many patients, the disease quickly progressed to something much worse than the sniffles.
Extreme chills and fatigue were often accompanied by fluid in the lungs. One doctor treating the infected described a grim scene: In the morning, the dead bodies are stacked about the morgue like cordwood.
There is no cure for the influenza virus, even today. All doctors could do was try to make the patients comfortable, which was a good trick since their lungs filled with fluid and they were wracked with unbearable coughing. The lucky ones simply drowned in their own lungs. The unlucky ones developed bacterial pneumonia as an agonizing secondary infection.
The pandemic came and went like a flash. More than half a million died in the U. Black Death — It began in South-western or Central Asia and spread to Europe by the late s. The total number of deaths worldwide from the pandemic is estimated at 75 million people; there were an estimated 20 million deaths in Europe alone.
The three forms of plague brought an array of signs and symptoms to those infected. Bubonic plague refers to the painful lymph node swellings called buboes, mostly found around the base of the neck, and in the armpits and groin.
The septicaemic plague is a form of blood poisoning, and pneumonic plague is an airborne plague that attacks the lungs before the rest of the body.
The classic sign of bubonic plague was the appearance of buboes in the groin, the neck and armpits, which oozed pus and bled. Victims underwent damage to the skin and underlying tissue, until they were covered in dark blotches.
Most victims died within four to seven days after infection. When the plague reached Europe, it first struck port cities and then followed the trade routes, both by sea and land.
Of those who contracted the bubonic plague, 4 out of 5 died within eight days.Analysis of Issue Causes of AIDS There are many factors that cause Acquired immune deficiency syndrome (AIDS). In an essay written by David Herlihy, entitled "Bubonic Plague.
Abstract. Dendritic cells (DCs) are the most potent class of antigen presenting cells and are versatile regulators of antigen-specific immune responses.
Because of their seminal r. Pneumonic plague, the only transmissible form of the infection, can occur from spread of the bubonic stage through the bloodstream or be acquired airborne from someone else with pneumonic plague.
What is the difference between the pneumonic plague and bubonic plague - What is the difference between the pneumonic plague and bubonic plague? Bubonic plague is the most common form of disease and arises following a bite from a flea that has previously fed on an infected animal (Poland and Barnes, ).
The bacteria are disseminated from the initial site of infection to the draining lymph nodes, which become swollen and tender, forming a bubo.
