Covering Communicable Diseases During CNA Training

CNA training is compulsory if you want to make a career in the medical field. It covers all the technical and practical things you have to do in the job. It not only makes you eligible to step into the healthcare sector but also to pass the certification exam.

Before offering the job, employers will check your registration with the local nursing board. It will prove to them that you are a trained person and can handle the duties and responsibilities of a certified nursing assistant. More importantly, the certification will ensure that you have covered communicable diseases during CNA training classes.

Communicable diseases have taken its tolls on many people. Most of the death cases found in the world relate to this type of disease. Through newspaper and TV news, we come to know that people are affected by contagious diseases, and their conditions are serious. Medical science has discovered many such diseases, which not prevented in time can cause death on a large scale.

This condition may spread with problems like flu, pneumonia, and dengue. People exposed to the virus, and bacteria can be affected. Therefore, it is important to understand the symptoms and cure for all these communicable diseases.

Nursing training concentrates more on controlling the spread of communicable diseases. This is because nursing assistants work in direct contact with patients. They spend more time than doctors and nurses with patients. They manage lots of activities in the ward while providing care to patients.

This is why they are more susceptible to infection and are an easy target for contagious diseases. The following are the topics covered during CNA training classes to prevent communicable diseases.

Importance of Hand Hygiene

This is the basic of hygiene. We have already learned from our parents and teachers in schools that we should keep our hands clean, and wash it with soap and warm water after touching soiled substances. This principle of cleaning is again repeated during certified nursing assistant training.

Instructions in washing hands before and after meeting patients, using gloves and covering face with a mask when cleaning wounds, handling tongs and scissors with caution to prevent cuts are few lessons nursing assistants go through during the training session. It also covers the use of disinfectants, antibacterial and sanitizers.


Infection develops through spoiled materials. When you touch those substances with open hands, you are allowing access for bacteria and viruses to invade your body.

In a healthcare facility, an infection can spread through many materials such as bed linens and utensils whether it is for eating purposes or for eliminating body waste.

Patients on the bed are in direct contact with bed linens. It is possible that few drops of blood, saliva, urine or stools will get spilled on the linens, which are easy scope for contamination.

Therefore, during nursing aide training classes, nursing assistants are taught how to maintain distance while folding and wrapping bed sheets in plastic bags and safely transfer them to the laundry.

Keeping the environment free from contamination

This is important in order to keep the surrounding area clean and free from intrusion. The spills that are on the floor while dressing wounds have to be cleaned immediately.

It is also necessary to sanitize or sterilize the area to kill the possibility of spread. Certified nursing aide training classes help nursing assistants to realize the necessity of removing harmful waste as soon as possible.

Each healthcare setting will have a distinct procedure to handle unhealthy and unsafe substances. CNAs have to get accustomed to the facility’s method of working.

Safety and Precaution

The certified nursing assistants have to work with sharp objects such as injection, catheters, scissors, etc. The chances of injury or accident while handling these types of instruments are higher. These tools have to be handled cautiously so that they do not cut patients or themselves accidentally.

When such incidence occurs, the nursing aide has to inform the supervisor immediately to take timely measures and restrict the expansion of communicable diseases, since a virus and bacteria can enter the body through cuts and prick. It is also important to use disposable materials when extracting blood samples, or giving injections. Doing so will stop the chances of contamination.

Few tools in healthcare settings are used repeatedly. It is the responsibility of a certified nursing assistant to sterilize the equipment properly before it is used again.

These are major topics covered in CNA training classes to prevent communicable diseases. Before getting into the job, nursing assistants have to read the manual to understand the policies and procedures of the facility. Though the working style may differ in healthcare settings, the main purpose still will be to stop communicable diseases from spreading.
