Denver is a good place to work as a CNA. Estimated hourly rate start from around 10 dollars and annual salary can be as much as 22,000 to 29,000 dollars. As a result, many are aspiring to pass the regularly held CNA Exam Denver and gain certification. So, have you already done the right preparations? To help you with one of the subjects that will be covered in the exam, in this article you will learn important points about communicable diseases.

Definition

It may appear in other terminologies such as infectious diseases, contagious diseases, and/or transmissible diseases. The idea is that diseases falling under the category of communicable are caused by microorganisms also called pathogens such as bacteria, viruses, fungi, and parasites. Also, the infection can be transferred from one individual to another through different means.

Because of this nature, patients with communicable diseases may have to be handled differently. Some may need to be placed in separate rooms. Health care personnel such as doctors and nurses may need to protect themselves as well from infection. They may wear gloves and masks.

Types

As already mentioned, communicable diseases are causes by microorganisms which are also called pathogens. These pathogens fall under two types: primary and opportunistic. Starting with primary pathogens, these microorganisms can infect a person regardless of his/her health state. Its presence alone can result in the development of the disease.

On the other hand, opportunistic pathogens can only develop into communicable diseases if the conditions are right. For example, if a pathogen is transferred into an individual who has strong immunity, it may not develop into an infection.

Transmission

There are several ways in which communicable diseases can be transferred. If you want to be a CNA and will be taking the Denver CNA Exam, knowing this will protect you from communicating the disease of patients that you will handle. Depending on how the pathogen is transmitted, it can be referred to as waterborne, airborne, or vector.

Waterborne diseases can be transferred via fluids. Airborne is very dangerous because simply inhaling the pathogens that got caught in the air can communicate the disease. Some however need a vector as a means of transfer. Example of vector is mosquito which can be a carrier of Malaria.

Common diseases

The state exam for CNA may include questions about some of the most common communicable diseases. One that is very worrisome in hospitals because of its resistance to many antibiotics is the skin infection called MRSA or methicillinn-resistant Staphylococcus aureus.

Other common infections are tuberculosis, pneumonia, and influenza which can easily be communicated by air. Also, there are communicable diseases which can be transferred by mere skin contact. One example is scabies.

Terminologies to keep in mind

To better your chances in that upcoming CNA state exam test, be sure to familiarize yourself with these terminologies:

1) sepsis: a system-wide response to an infection,
2) pathogen: a germ or microorganism that causes disease,
3) antisepsis: prevention of sepsis,
4) infection control: methods used to contain the infection and prevent spreading
5) isolation: a method of preventing the spread of disease by isolating the patient and avoiding contact with others
6) medical asepsis: methods used to reduce presence of germs in the environment.
