Answer:
An epidemic is an occurrence of disease that is temporarily of high prevalence. An epidemic occurring over a wide geographical area is called pandemic.
The rise and decline in epidemic prevalence of an infectious disease is a probability phenomenon dependent upon transfer of an effective dose of the infectious agent from an infected individual to a susceptible one. Following an epidemic, the host population becomes susceptible because of the deterioration of individual immunity; the removal of immune individuals by death; and the influx of susceptible individuals by birth. The time elapsing between successive epidemic peaks is variable and differs from one disease to another.
Environmental crises, such as flood, drought, earthquake and landslide, lead to spread of a number of epidemic diseases such as plague, measles, diphtheria, cholera, influenza, diarrhoea and malaria. A brief survey of some of the important epidemic diseases is given below.
Plague Plague is an infectious fever caused by the bacillus Yersinia pestis, which is transmitted by the rat flea. It is primarily a disease of rodents; and epidemics in human beings originate in contact with the fleas of infected rodents. The disease in man has three forms: (a) bubonic (swelling of the lymph nodes); (b) pneumonic. (involvement of lungs); and (c) septicemic (invasion of blood stream). Plague has also been classified on the basis of the area of its occurrence: murine or urban plague in urban areas, and sylvatic or campestral plague in desert or rural areas. Bubonic ‘ plague constitutes about three-fourths of all plague cases.
In the 14th century, the plague epidemic in Europe resulted in the death of one-fourth of the population or 2.5 crore people of the continent. The Great Plague of London in 1664-65 resulted in more than 70,000 deaths in a population estimated at 4,60,000. An outbreak in Canton and Hong Kong in 1894 left 80,000 to 1,00,000 dead, and within 20 years the disease spread from the southern Chinese ports throughout the whole world, resulting in more than one crore deaths.
In India, the epidemic, originating in Surat (Gujarat) spread in eight states in the period August-October 1994. It killed 53 of 5,150 infected people. The devastating earthquake in Latur (Maharashtra) in 1993 was held responsible for the outbreak of plague. It may be mentioned here that Bir, the most affected region of Gujarat, and Latur are not far away from one another. Further, heavy rain and flood in Surat in that year had resulted in heavy deaths of animals, which made the flea to turn to other host (man). Plague spread in Himachal Pradesh as recently as February 2002.
According to specialists, any change in the ecology of rats may become the cause of plague. Deforestation is one such change. Due to deforestation, wild rates take refuge in nearby human settlements. These rats carry along with them the plague-causing agent
We asked students how their lives have changed since the onset of this pandemic. They told us about all the things they miss, what it’s like to learn online, and how they’re dealing with the uncertainty. But, they also pointed out the things that have brought them joy and peace amid the chaos.
Life as we know it, upended
Yesterday my school district announced that our school would be closed until May 5. Upon receiving the email, I immediately contacted my friends to share our responses. To most of my friends and me, this news was no surprise. Already finishing week one of quarantine, I find myself in a state of pessimism in regards to life in the midst of a pandemic. My days have blurred into Google Classroom assignments, hobby seeking, aimless searching on Netflix, and on exceptionally boring days, existential contemplation.
The dichotomy of chance freedom from school and yet the discombobulated feelings of helplessness and loneliness plague my time home alone. My parents are yet working and as an only child, I try my best to stay sane with blasting music and shows. Other times I call my friends to pass the time doing school assignments. Even then, schoolwork seems increasingly pointless.
With most of my classes being APs, the recent CollegeBoard update for the 2020 AP exams was a blow to my educational motivation.
