The Outbreak

Introduction With the end of the war, all the countries have evoked the ultimate peace in the world ... but that is wrong. This is 80 degrees morning wet in Miami, Florida. Jack just woke up to school. He is a smart and intelligent child. His mother and father are very happy with such a son. But one day, I did not know they are the last to meet him. They sent him to school. That's when they came in ... they entered so early that he had no time to protect themselves.

In the Middle Ages, the occurrence of glandular plague repeatedly destroyed the population of Europe. The great plague (1665 - 66) was the last major epidemic in London. With that outbreak, an estimated 100,000 deaths corresponded to about 15% of the city's population at that time. As the number of victims begins to increase, the burial ground will be in a competent state and a hole will be drilled to accommodate the dead. These biggest ones are in Aldogate, where it is estimated that more than 1,000 plague victims are buried in anonymous pits.

As a study of vector mediated diseases, let's think about plague. With countless occurrences recorded for centuries, the plague caused millions of deaths. Pestogenesis still exists. Plague is caused by bacteria Yersinia pestis. Historically rats were common, with the occurrence of a large occurrence of plague among them, it has long been considered a disease transmitted directly by rats. Bacterial cells collect and attach to the valve between the gastrointestinal tract and the esophagus. The valve cover has a spine structure. The glandular stomach usually allows blood meals to enter the midgut and prevents blood from flowing back into the esophagus.

There were several historic plague occurrences, including the occurrence of pests in Hong Kong in 1984 and pulmonary plague in Manchuria from 1910 to 1911. The plague of 1984 was also known as "Black Death" because the whole body is colored black. Before and after the death, it was confirmed later as a gland plague. Pneumonic plague is unique, it is completely pneumonia (lung infection). Patients with pulmonary plague may develop cough, usually accompanied by hemoptysis (hemoptysis), headache, weakness. Both diseases caused outbreaks, but the government at that time had different management and measures.

The devastating plague occurred periodically between the middle of the 14th century and the 17th century. One outbreak known as pandemic disease (1665-1666) is presumed to have living expenses in London and one fifth of the population of 107,500,000. Prior to the Industrial Revolution, the standard of living has hardly changed. If we set real UDP per capita GDP to 100 in 1566, it increased to 130 in 1806. This means that the annual growth rate of per capita income for 240 years is 0.11%. In other words, there is no major improvement in the quality of life for most people on average.
