“The work of epidemiology is about unanswered questions, but also uncontested answers” ​​- Patricia Buffler. The science that examines when and where infections occur and how they are communicated to the public is called epidemiology. Say no to plagiarism.

John Snow, a British doctor, led a series of examinations related to the cholera outbreaks in London. The study of disease transmission deals with the occurrence and spread of disease within a given population. The study of disease transmission focuses on life forms or specialists that can spread irresistible infections among humans and other populations of creatures. To track the onset and pattern of spread of an unstoppable infection outbreak, it is important to find out which microbe we are paying attention to. Disease transmission experts explore five links within the infectious disease cycle, including: characteristics of the microbe, source and repository of the microorganism, mode of transmission, host susceptibility, output components . The attributes of the microorganism involve the type of microbe, such as what it means to individuals, whether it is treatable, how it enters the host cell. Then, at this point, the source of the microbe involves where a particular microorganism came from, what is the ancestor of that microbe. Furthermore, the method of transmission involves how a particular microorganism communicates from one host to another host. Furthermore, host vulnerability involves a specific type of microbe ready to make all hosts sick or not. Finally, the discharge system involves how we are going to repair or eliminate this type of microbe. These kinds of things or areas that a disease transmission specialist can work for. The discipline of epidemiology is broadly defined as "the study of how disease is distributed in populations and the factors that influence or determine this distribution." Among a range of recognized basic epidemiological functions, monitoring and surveillance and the investigation of outbreaks are most immediately relevant to identifying and stopping the spread of infectious diseases in a population. There are a few steps a disease transmission specialist can take to control pandemics for an infectious microorganism. There are three types of steps a disease transmission specialist can take. The first type aims to reduce or eliminate the source of the disease. There are different ways to do without the source. These are: isolation and disengagement of carriers, now we will understand the circumstances of coronavirus. When a person is affected by coronavirus, specialists or health experts say that the person in question should remain separated from others because due to coronavirus infection, the person has become the carrier of coronavirus which can influence the others. Then, at that moment, after the destruction of a creature depositing the contamination, we realize as a whole that female mosquitoes of the adis type are the carriers of dengue. This way, if we kill the mosquitoes, we will be ready to eliminate dengue. From then on, wastewater treatment to reduce water contamination. If individuals are influenced by waterborne bacterial disease, they should treat the sewer line with the.
