7. ReviewCOURSE OUTLINE
The School of Rural Public Health at the Texas A&M Health Science Center cares about keeping employees and students healthy. No one likes to catch a respiratory illness or other infectious disease from someone at work.
Germs can spread rapidly in an office or other workplace setting so it is very important to stay informed and active in protecting yourself and others from the common cold, flu, and other infectious diseases.
We all know that simple steps like hand washing are most important in preventing infection but sometimes it is easy to forget exactly how to stay healthy, especially with increased stress at work and school.
This course is intended to be a reminder about how to prevent the spread of infectious diseases and maintain a healthy environment in the university setting.
a disease that is caused by microorganisms such as bacteria, fungi, viruses, protozoa, and parasites that can successfully spread, invade, establish, and grow within a host’s tissues
an infectious disease that is easily transmitted from one person to another
What is Influenza?
An acute illness caused by the influenza virus from the family Orthomyxoviridae, much different than the common cold virus
Highly infectious disease that can spread rapidly from person to person through airborne droplets of saliva or other body fluids as well as from contaminated surfaces or objects
Some strains cause more severe illnesses than others
There are three types of influenza that we hear about today:
Influenza is easily passed from person to person and is transmitted through breathing in virus containing droplets that are produced when an infected person talks, coughs, or sneezes.
You may also spread the flu virus through touching an infected person or surface contaminated with the virus and then touching your own or someone else’s face.
Sudden onset of symptoms include fever, headache, aching muscles, severe weakness and respiratory symptoms, i.e. cough, sore throat, difficulty breathing.
Incubation estimates vary. The range is generally from 1 to 14 days
with most in the range of 2 to 3 days.
The flu and common cold are respiratory illnesses with shared symptoms but are caused by different viruses. Influenza is a more severe illness than the common cold.
Infectious diseases can be transmitted (or spread)
through four routes of exposure:
Direct Contact: contact of eyes, nose, mouth, genitals, skin, cut, or other open wound with an infectious agent or an infected person’s blood, or other body fluid
Indirect Contact: infectious agent on inanimate object such as a desk, keyboard, or phone is picked up and introduced into the body
There are three types of transmission:
MAINTAINING A CLEAN AND INFECTION FREE
ENVIRONMENT IN THE UNIVERSITY SETTING:
High traffic surfaces in a university setting can be a source of many growing pathogens. Main areas should be cleaned when visibly soiled and on a regular basis:
Employees and students should make good choices about personal hygiene and illness prevention.
Use discretion when experiencing these or other symptoms of sickness. It is more beneficial to stay home and recover than to provoke symptoms further or spread disease to others.
Many adults tend to minimize the importance of handwashing but this is one of the best defenses against the spread of infectious disease. Using proper technique is essential to sanitizing hands effectively. Inadequate handwashing can cause significant areas of the hands to be missed. It is important to cover all areas of your fingers, hands, and wrists.
Handwashing is the most important step to prevent the spread of infectious agents. Proper handwashing has three necessary ingredients:
If you are responsible for cleaning in the university setting, or if you choose to do extra disinfecting of your own workspace, it is important to be informed about the correct usage of disinfectants and cleaners.
Too weak of a solution will be ineffective. A stronger solution than is recommended is wasteful and may lead to problems of corrosion with equipment and surfaces, as well as health problems. Residue may also harm feet, eyes, and other sensitive areas.
Equipment and receptacles used with disinfectants should be thoroughly cleaned and rinsed after use. Any organic material present may reduce the effectiveness of the disinfectant.
A disinfectant should have no substance other than water added. Combination of chemicals can negate the effect of active ingredients in products as well as produce harmful fumes or cause corrosion.
It is vital to live a healthy lifestyle to protect against illness. This includes eating nutritious foods, getting enough rest, and exercising in addition to the infection prevention and hygiene training presented in this lesson.
Seasonal Flu - mild to severe respiratory illness transmitted human to human each year. The best protection against seasonal flu is vaccination.
Avian Flu - caused by the avian Influenza (bird flu) virus that occurs naturally among birds worldwide.
Pandemic Flu - global outbreaks of a newly emerged strain of Influenza.
