17 May Infectious Diseases

What are Infectious Diseases?
According to Mayo Clinic, infectious diseases are disorders caused by organisms such as bacteria, viruses, fungi, or parasites. Many organisms live in or on our body and are normally harmless or even helpful to our bodies functioning properly, but some organisms can be harmful. In the healthcare industry, there is a higher chance of occupational exposure to the more harmful organisms that could cause disease.
There are three primary routes of transmission in U.S. healthcare settings: contact, droplet, and airborne. Contact transmission can be through either direct or indirect contact. Direct contact transmission of an infectious agent is from an infected individual to a susceptible individual through physical contacts, such as skin-to-skin contact. Indirect contact occurs when infectious agents are transferred to an individual through contact with a contaminated surface or item.
The healthcare industry can encompass a variety of workplace settings, including hospitals, nursing care facilities, outpatient clinics (e.g., medical and dental offices, and occupational health clinics), ambulatory care centers, and emergency response settings. The diversity among healthcare workers and their workplaces makes occupational exposure to infectious diseases especially challenging due to varying job positions and the risk of occupational exposure to infectious agents.
Bloodborne Pathogens
OSHA defines Bloodborne Pathogens as “infectious microorganisms in human blood that can cause disease in humans.” Needlesticks and sharps-related injuries have the potential to exposure healthcare workers to a bloodborne pathogen. The pathogens that are most concerning when exposed to blood and other bodily fluids are the human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV). Healthcare workers should utilize available engineering controls, safe work practices, and personal protective equipment (PPE) to protect themselves from exposure.
Engineering controls that should be implemented include Safer Devices and Sharps Disposal Containers.
Other Diseases
COVID-19
COVID-19 is an airborne disease that mostly travels in respiratory droplets from coughs, sneezes, talking, or breathing from an infected person. These droplets can then land in the mouths, noses, or eyes of someone within 6 feet of the infected person.
Slow the spread of the COVID-19 pandemic:
- Wear a mask that covers your nose and mouth to help protect yourself and others.
- Stay 6 feet apart from others who don’t live with you.
- Get a COVID-19 vaccine when it is available to you.
- Avoid crowds and poorly ventilated indoor spaces.
- Wash your hands often with soap and water. Use hand sanitizer if soap and water aren’t available.
Influenza (Flu)
The Flu is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness. Serious outcomes of flu infection can result in hospitalization or death. There are two main types of influenza (flu) virus: Types A and B. The influenza A and B viruses that routinely spread in people (human influenza viruses) are responsible for seasonal flu epidemics each year. The best way to prevent flu is by getting vaccinated each year.
Methicillin-resistant Staphylococcus aureus (MRSA)
MRSA is a bacterial infection that is usually spread in healthcare settings via direct contact with an infected wound or from hands that have come in contact with the active infection. The only way to know if an infection is caused by MRSA is to perform a culture of the bacteria. It is crucial to prevent the spread of MRSA through PPE and hand hygiene practices because the bacteria has become resistant to some antibiotics.
Tuberculosis (TB)
TB is a contagious infectious disease caused by a bacterium called Mycobacterium tuberculosis and is spread through airborne transmission. Droplets containing the TB bacterium can be released into the air when an infected person coughs, sneezes, talks, or otherwise expels air that can release the droplets.
How Can Employers Protect Employees?
1) Train employees how and when to perform Hand Hygiene. Here are some recommendations from the Centers for Disease Control and Prevention (CDC) regarding Hand Hygiene:
Use an Alcohol-Based Hand Sanitizer
- Immediately before touching a patient
- Before performing an aseptic task (e.g., placing an indwelling device) or handling invasive medical devices
- Before moving from work on a soiled body site to a clean body site on the same patient
- After touching a patient or the patient’s immediate environment
Wash with Soap and Water
- After caring for a person with known or suspected infectious diarrhea
- After known or suspected exposure to spores (e.g. anthracis, C difficileoutbreaks)
- After contact with blood, body fluids, or contaminated surfaces
- Immediately after glove removal
- When hands are visibly soiled
2) Implement Engineering controls
3) Have safe operating procedures and exposure control plans in place
4) Provide Personal Protective Equipment that is appropriate for the task and potential exposures
Personal Protective Equipment (PPE)
Personal Protective Equipment (PPE) is equipment to provide a physical barrier to keep healthcare workers protected. Examples of PPE include, but are not limited to: gloves, gowns, safety glasses or goggles, respirators, masks, and face shields.
The PPE selected should be appropriate for the potential hazards associated with the tasks being performed.
Gloves: Should be worn when it can be reasonably anticipated that contact with blood or other potentially infectious materials, mucous membranes, non-intact skin, potentially contaminated skin, or contaminated equipment could occur.
Gowns: Should be worn to protect skin and prevent soiling or contamination of clothing during procedures and patient-care activities when contact with blood, body fluids, secretions, or excretions is anticipated.
Mouth, nose, & eye protection: Should be utilized to protect the mucous membranes of the eyes, nose, and mouth during procedures and patient-care activities or aerosol-generating procedures (e.g., bronchoscopy, suctioning of the respiratory tract [if not using in-line suction catheters], and endotracheal intubation) that are likely to generate splashes or sprays of blood, body fluids, secretions, and excretions. Select masks, goggles, face shields, and combinations of each according to the need anticipated by the task performed.
