The Use of Variola major in Bioterrorism Essay -- Biological Terrorism

Variola major: its symptoms and the possibilities of its use in bioterrorism Smallpox is a virus that was pronounced eradicated in 1990 by the World Health Organization (WHO). Prior to its elimination through the coordinated efforts of several international agencies, it was considered one of the most dangerous threats to the prolonged existence of the human race. Its effects, especially those of the hemorrhagic strain, are comparable to those of such agents as the Zaire Ebola virus, Lassa hemorrhagic fever, and Marburg virus. EPIDEMIOLOGY Smallpox (Variola major) spreads through either direct physical contact or prolonged proximity to an infected individual. The disease begins in the lungs, spreading from there to the rest of the body. Men and women are equally susceptible to the disease, as are all ethnicities. Of those who came in contact with the disease, few survived. The mortality rates are these: Discrete ordinary smallpox: 34% Confluent ordinary smallpox: 59% Hemorrhagic smallpox: 94% Smallpox was known to nearly wipe out entire populations, and often decimated communities, cities, and countries. POSSIBLE BIOWARFARE USES FIRST USE The first recorded use of smallpox as a biological weapon was in 1756. Sir Jeffrey Amherst and other members of the British colonial army gave blankets that had previously belonged to smallpox victims to American Indians, causing them and their tribes to contract the disease previously unknown to them. In some areas, more than 50% of the population perished. WORLD WAR II During the second world war, the Axis decided to begin the usage of biological weapons in order to assure that the war went in their favor. This task was assigned to Japanese Military Unit 731, which recruited numer... ...(2005) Biological weapons defense: infectious diseases and counterbioterrorism. New York: Humana. Smallpox.

Children and education Essay

?Children’s mind is considered as white sheets, so it is easy for us to write on them as we want. In fact, some experts believe that children should begin to learn foreign language at primary school. In my opinion, there are many advantages to learn a target language as a child. First of all, the most advantage is they can learn a great number of vocabularies. Take my brother an example. He began studying English when he was six years old. Therefore, he knows many thematic vocabularies. Having graduated from high school, he finds it easy to communicate with foreigners by a wide knowledge. Next, learning foreign language as child helps children to imitate rightly pronunciation of native languages. For example, my daughter in grade two learns English two days a week. She often listens to songs and stories by native’s voice. As a result, she can imitate their voice and rhythm to pronounce rightly. Last but not least, another advantage is they can remember the pattern sentences longer. They can practice some patterns by repetition method. In reality, ones are repeated so many times that they remember them deeply, and that helps them to reflect quickly in context communicate. In brief, with above-mentioned reasons, it is better for children to begin learn foreign language at primary school than at secondary school. They will achieve a wide, strong knowledge as well as their self- confident to enter a bright future. Learning a foreign language at primary school or secondary school is very necessary for children. However, some people think that it is better for children to begin learning a foreign language at primary school rather than secondary school. There are a lot of controversial opinions about this problem. In my opinion, I agree with this statement because of the following reasons. Firstly, learning a foreign language at primary school helps children develop their skills better. Nowadays, children of all primary shcools in the nation have to study the foreign language, mainly English. At primary school, children have focused on learning vocabularies, how to pronounce†¦At this age, the children’s brain is developing so it is very easy for them to learn the foreign language. Moreover, the children of primary school have a lot of time and conditions to learn the foreign language because they have less subjects at school. The chidren should begin learning the foreign language at primary school because it will help them to develope their skills including reading and speaking skill. If the children begin learning the foreign language at secondary school, they will face a lot of difficulties in their study because they do not have the basic knowledge of foreign language. At secondary school, the children have to spent more time on different subjects, therefore they do not have more time to learn the foreign language. Secondly, to begin learning the foreign language at primary school helps the children to pronounce more exactly. The program of teaching and learning the foreign language at primary school and secondary school is different. If the children begin learning the foreign language at secondary school, they will study more skills such as writing, speaking, reading, listening, grammar and new words. Hence, it is not good for children to begin learning the foreign language at secondary school. Unlike the secondary school, the children of primary school only learn the vocabularies, the way of pronunciation and simple sentences. Learning the foreign language at primary school will create many favorable chances for children to prepare firm knowlegde and this hepls them to learn the foreign language at secondary school better. In conclusion, to begin learning the foreign language at primary school is better than secondary school. The children should begin learning the foreign language at primary school because this is an important period that hepls them build basic knowlegde of foreign language.

Firstly, the FDA is partially to blame. While they do not require animal testing, they do require that the safety of a product be demonstrated satisfactorily. Besides the FDA, several large corporations that play a huge role in this problem. Most of the more popular makeup brands (L’Orà ©al, Estee Lauder, Johnson Johnson, etc.) test on animals.
