Essay – Biological disasters
Biological disaster is one of the important subjects in the world now a days. The disaster the word itself suggest that it is one of them hazard to the living organisms. It may involve diseases, any natural calamities or anything which is providing harm to the living organisms. The biological disaster one of the new terms which is used very prominently after Corona. Biological disaster is spread of disease due to any living organism, that living organism can be microorganisms such as bacteria, fungi, viruses, parasites, algae etc. When diseases are spread through a microorganism is called as biological disaster. Many of the times question arises how this biological disaster arises or what is the source of this biological disaster, so now a days our scientist can answer our 99% questions.
Biological disaster mainly arises through various bacteria, fungi, viruses and parasites. These microorganisms are generally present everywhere on the earth but the problem arises when the non-pathogenic form of microorganism convert into pathogenic form. Pathogenic form of the microorganism is the form when the organism is able to cause the disease and that’s how biological disaster starts. As the microorganism are present everywhere such as on any object, on food, in air, in water, on the human body as well as plants and animals, in the human gut, in soil etc. The presence of microorganisms everywhere signifies the importance and functions of microorganisms. The functions of microorganisms signify us the microorganisms or bacteria can be good their presence can be good when they are in non-pathogenic form. Microorganisms perform various functions such as in plant growth, to decompose the food, to digest the food, to increase the soil fertility etc. Along with the uses of microorganisms there are certain disadvantages of microorganisms. When the bacteria convert from non-pathogenic to pathogenic form it can cause disease such as water Borne disease, food Borne disease,Tick borne disease, mite Borne disease and zoonotic disease.
The major examples of microorganism Borne disease are malaria and dengue which is caused by the bite of mosquito, typhoid which is caused by contaminated food due to the presence of pathogen salmonella typhi, HIV caused by the virus human immunodeficiency virus due to contaminated blood or contaminated fluid.
This microorganism causes various hazards to the living organisms, as the spread of disease through the microorganism occurs through various ways such as disease can be contagious (direct contact), this is can spread through food, water, respiratory droplets or it can be indirect transmission. The modes of transmission of the disease through the microorganisms are responsible for epidemics (when the number of patients increases unexpectedly in a particular area is called as epidemic), pandemic (win the number of patients increases worldwide is called as Pandemic), endemic (diseases which are normally found in a particular area).
The major example of biological disaster was covid-19. The disease was spread through direct contact as well as indirect contact and the causative agent of the disease is corona virus. The disease was declared as pandemic by the scientist. As in covid-19 more than Crores of lives lost. The outbreak occurred in 2019.
Like the covid-19 in earlier also various disease out to break had observed such as plague, cholera, swine flu, encephalitis etc. Therefore due to the outbreak of various diseases the government is now then more careful about the hygiene, cleanliness etc. Now a days government is more concern about the health and therefore spreading the awareness among every population, to aware the people about the biological disaster. To prevent such biological disaster, precautions are necessary such as washing the hands with soap or any hand wash after using the washroom, before taking the meal and after sneezing and coughing, personal care such as Daily Bath, daily clean and wash clothes, cutting the nails. To boost the immunity, eat the healthy food in the sense nutrients, proteins, vitamins to prevent the immunodeficient condition and drink at least 3 litres of waters per day to overcome from dehydration condition.The health workers should wear hand gloves, personal protective equipment kit (ppe kit), should wear mask when working with the patients, should dispose them medical garbage very carefully in order to prevent any contamination or any contaminated disease. Used syringes should be disposed in a proper manner.Now a days our government is also spreading awareness among the people about the vaccine. At the people having some fear about the vaccines and its effectiveness, but the vaccine is only for the purpose of precaution to prevent any disease such as polio vaccine, MMR (Measles, Mumps, Rubella )vaccine etc. Along with the vaccines, through various medium an importance of exercise and weight management are also there to overcome the obesity. The household garbage should be disposed in a clean and neat manner such as the wet garbage and dry garbage, disposal of sanitary napkins, diapers of baby and the Kitchen waste should dispose in a well manner.This biological disaster teaches us the cleanliness, importance of hygiene and the healthy food. As the government is spreading the awareness among all the people, therefore the name biological disaster chapter added in the science text book so that students can learn various good habits from the childhood itself.
In the science text book, one of the chapter on microorganism is added so that students will get the information about the diseases and the microorganisms their benefits as well as uses from the childhood.Therefore the biological disaster is one of the up bringing topic, everyone should know about it and the importance of microorganisms with their uses and disadvantages. Biological disaster is nothing but the mistake of human in their day-to-day life. If everyone follow the ethics and manner of cleanliness then the war or the disaster against the microorganisms can be win.Therefore let us come together for the better future of Earth, us and our upcoming generations to live a healthy life with good habits and win the war against the microorganism.
