Hey everybody Dr. O again Uh, doing some more terminology to help you classify different types of infectious diseases. So today in this video we are going to talk about communicable diseases vs noncommunicable diseases and then contagious diseases. So let’s start with noncommunicable diseases. These are diseases that are not spread from one host to another, from one person to another. So the textbook example of this would would be uh, um, tetanus right? You get tetanus from um, the soil, stepping on a rusty nail whatever the, whatever the example you want to use. But that but you are not going to give that to somebody else right? So that’s a noncommunicable disease. A communicable diseases is spread from one host, one person, to another. So uh, communicable, so think about your sexually transmitted diseases, sexually transmitted infections, these would be examples of communicable diseases. What you actually get it from someone else. We will talk about the different types of transmissions in in other videos. Contagious diseases I would say, the keyword here is easily right? So, a contagious disease is a type of communicable disease that is spread easily and quickly, rapidly from one host to another. So I think about uh, the flu is a good example, but to me, the best example of a contagious disease is measles. I’ve seen some data that shows that if someone was, if yo-you know no one’s vaccinated, there was no immunity, if someone was in the room that you enter 4 hours ago with measles you might have a 90 plus percent chance of actually uh, getting that infection. So that would be an example of a contagious disease. So communicable diseases are spread from one host to another, um contagious diseases are easily spread from one host to another and noncommunicable diseases are not spread from one host to another directly. Alright, I hope this helps. I hope you have a wonderful day. Be blessed!
