Document Summary

Epidemiology: study of the factors of spread and maintenance of disease in populations. Incidence/morbidity rate: number of new cases in a defined population over a specific period. Mortality/death rate: number of deaths in a defined population over a specific period. Endemic disease: always present in the population of a particular geographic area. Epidemic disease: a greater than usual number of cases in a particular geographic region, usually within a short time span. Cases increase to a maximum then rapidly drop off. Hospitals: only a small number of infected patients can constitute an epidemic. Observed clustering of cases around water pump. Occurs in epidemic proportions in many countries simultaneously. Influenza a the spanish flu (1918) Reservoir: any site where the pathogen may multiply or survive until transferred to a host. Promote international cooperation, control and eradicate disease. Administered by us department of health and human services. Water pollutants can be chemical or biological. Waterborne epidemics are more common in third-world countries.

Tetanus; infamously known as lockjaw. This disease is found worldwide. Non-communicable diseases that will literally make your muscles tighten. Tetanus is not your typical disease. It is not spread person to person but through scraps, cuts, or any open wounds that break the skin. The incubation period for the disease is anywhere from 3-21 days depending on the wound and how contaminated the object was. The bacterium enters through these wounds and attacks the body affecting mostly the muscles. Most cases occur in people who are not vaccinated or do not maintain their boosters. Boosters are needed every ten years to prevent the disease. Although we cannot prevent injuries that cause the body harm we can prevent the disease from affecting our bodies through vaccination administration.

Tetanus cannot be tested but is diagnosed by physical examination conducted by a licensed physician. The diagnosis is based off physical examination and the reports from the patients about the symptoms they are experiencing. Some of those symptoms include; seizures, body aches, muscle spasms, jaw cramping, difficulty swallowing, headaches, fever, sweating, changes in blood pressure, and changes in their heart rate. Other complications can develop depending on a person's individual health and health history.

The best way to prevent Tetanus is by preventing it with the Tetanus vaccination and the boosters that are needed every ten years. This vaccination could be administered by a number of ways. There are four different types of combinations that include the Tetanus vaccination; Diphtherias & Tetanus (DT), Diphtherias, Tetanus, & Pertussis (DTaP), Tetanus & Diphtherias (Td), and Tetanus, Diphtherias, & Pertussis (Tdap).Tetanus is administered at six weeks old, ten weeks old, and fourteen weeks old. Boosters are given three different times during childhood to keep the children up to date on vaccinations that prevent the disease. People affected by Tetanus are not immune to getting Tetanus again like some other known diseases.

According to the CDC (Center for Disease Control) in their article about Tetanus they reported that Tetanus cases have been on the decline by more than 95% because of the increase in vaccinations being distributed worldwide. The CDC also reported that deaths in the United States are on the decline and have declined more than 99%. According to WHO (World Health Organization) in 2016 there are only 13, 502 reported cases globally. They also reported that 86% of the world is covered by the Tetanus vaccination. According to the World Health Organization there are currently 8 countries in the world that have 50% of their population affected by Tetanus. The other 50% are reported to have received their Tetanus vaccination. Majority of those countries are found in the middle of Africa. There are currently 27 countries in the world that 50-79% of their population who have received their vaccinations. There are also 130 countries that have over 90% of their population who have been vaccinated.

Tetanus is a vaccine preventable disease in which everyone can be affected by. Vaccinations are currently a controversial topic everywhere. Vaccinations play an important role in helping prevent disease like Tetanus.
