This is the study of health problems within populations.
What is epidemiology?
According to the CDC, people who have this illness are most contagious in the first 3-4 days and on average 8% of the U.S. population get this illness. This is also a type of droplet disease.
What is flu or influenza?
This is a traditional model illustrating the interdependence of those that cause diseases, are susceptible to disease, the environment, the time it takes for symptoms to manifest and spread, and life expectancy of the ones susceptible to the disease
What is the epidemiology triangle?
This is the first factor in the chain of infection and is capable of producing a disease or illness.
What is infectious agents?
This type of prevention is getting involved in the prevention process before any illness occurs.
What is primary prevention?
What is epidemic?
This factor of the epidemiology triangle is the human or animal that is susceptible to the disease or illness.
What is host?
These allow a pathway into or out of a host.
What are portal of entry and portal of exit?
This type of prevention utilizes screening to identify disease in early stages before any signs and symptoms surface.
What is secondary prevention?
This is a disease or condition that is constant within a specific area and/or population.
What is endemic?
According to the CDC, this virus is spread through certain body fluids which attacks the body's immune system specifically the CD4 cells or T cells.
What is HIV/AIDS?
This factor of the epidemiology triangle is the cause of the disease or illness.
What is infectious agent?
This is the manner in which an agent moves from the reservoir to a susceptible host.
What is mode of transmission?
You engage in this type of prevention when you change a part of your lifestyle to better your own health.
What is active primary prevention?
This is an epidemic that has spanned over a wide area, usually multiple countries or continents, and affects a significant amount of the population.
What is pandemic?
This disease is usually transmitted by fleas carried by rodents or other small animals who are infected. In the middle ages it was a pandemic that killed millions in Europe.
What is plague or Yersinia pestis.
This factor of the epidemiology triangle is external to either the animal or human that enables the disease transmission.
What is environment?
This is the start of the transmission process once the pathogen leaves. According to the CDC this is the habitat in which an agent usually lives, grows, and multiplies.
What is reservoir?
This type of prevention occurs when you are managing a disease after the diagnosis.
What is tertiary prevention?
This is epidemiology that is focused on organizing and summarizing the data in regards to the people affected, time, and place.
According to the CDC, this endemic disease is spread through mosquito bites. Symptoms generally appear within 7-30 days but it can take up to one year to manifest.
What is Malaria?
This factor of the epidemiology triangle is the only factor which affects the other 3 factors equally but differently.
What is time?
According to the CDC, this is an individual's ability to resist disease that is attributed to their genetic or constitutional factors, specific immunity, and nonspecific factors.
What is host susceptibility?
This type of prevention occurs when legislation is written to ban or limit the use of products due to the negative health impact the produce has on the population.
What is passive primary prevention?
