Epidemiology

The episode “Deadly Messengers” in the video series, RX For Survival, shows the deadly diseases transmitted to people by mosquitos and black flies. The mosquitos served as transmitters to deadly diseases like the West Nile Virus, Yellow Fever and Malaria. Another insect born disease was River blindness, which was transmitted through tiny black flies. The video also shares how public health professionals helped the targeted populations reduce the risk of coming into contact with mosquitos as well…

As a laboratory analyst, I took it upon myself to monitor common instrument issues and eventually developed procedures to reduce the frequency of these recurring issues. Epidemiology can be seen as preventative maintenance for human beings. An epidemiologist monitors the health of a population and attempts to pinpoint recurring health issues to a common source. Also, as a health crisis develops, an epidemiologist will need…

time difficult, how the study was conducted could have been approached more carefully. Putting Madness in Its Place: Can the Environment Explain Schizophrenia’s Hereditary Patterns? Schizophrenia is a condition that have symptoms like hallucinations and disorganized thoughts; it does not have clear biological markers. One percent of the general population will be diagnosed with schizophrenia, but an offspring of a schizophrenic parent will have the odds jump to about one in 10. Schizophrenia…

How John Snow’s Skepticism and Open-mindedness Influenced His Method of Conducting Research At the beginning of the 18th century little was known about cholera transmission or disease communication in general. The miasma theory was in full force. Most of the science world accepted the miasma theory and completely rejected any other theory for disease transmittance. This greatly hindered advancements in research of communicable diseases because miasmas were understood as a fact and no…

with diseases flourishing, along with a sewer system that was leaking into the drinking wells. John Snow is a physician/anesthesiologist who first makes the link between Cholera and drinking water after studying previous cases. Snow founds the epidemiology center for the city but struggles with medical technology not being very advanced at the time and only being able to look upon incorrect means of disease transmission. Cholera attacked all throughout London, killing the wealthy and the poor.…

ROLE AND REFLECTION The Enhanced Surveillance Section (ESS) is part of the Surveillance and Epidemiology Division within the Centre for Communicable Diseases and Infection Control at the Public Health Agency of Canada (PHAC). ESS monitors the prevalence of HIV and other related infections, as well as associated risk behaviours through bio-behavioural surveillance among key populations (e.g. aboriginals, people who inject drugs, and men who have sex with men). The section also conducts national…

Recognizing, Ending, and Preventing Cholera Outbreak Cholera is a bacterial, diarrheal disease particularly rampant in developing countries where water sanitation is lacking. The focus of this paper is primarily on cholera’s outbreak history and disastrous effects on populations. This paper also discusses varying solutions that have been implemented in numerous countries with a focus on vaccine use in Haiti, one of the poorest countries in the world with a turbulent history, versus long-term…

There were several medical theories that emerged and held their merit for a period of time. However by the 1900’s, one concept had dominated the medical landscape. The continued development of medical theories symbolized the increased complexity of thinking between physicians and scientists. During the 1800’s, major infectious diseases like cholera, tuberculosis, typhus, and yellow fever strongly emerged in Europe with the etiology of these infections far to be known. Some of the early concepts…

Stress is caused by an event or series events in our environment which we perceive and respond in a variety of physiological responses in our bodies (Day, Whetham and Whetham, 2003). Stress is not only caused by negative events, it can also be caused by positive events in our lives such as getting a new job or starting a new relationship. These are called stressors, stressors are activities, events, or changes that result in stress on an object or organism. 
 Studies show that stress is not…

The Centers for Disease Control and Prevention, also known as the CDC is a federal agency managed by the Department of Health and Human Services (Rouse, 2014). Founder Dr. Joseph Mountain, visionary public health leader, had high hopes for what was at the time a small organization to prevent malaria from spreading across the nation (MMWR). The CDC targets many populations including local, state, and national levels to prevent and monitor outbreaks, put disease prevention strategies into effect,…
