Where does infect come from?
The first records of the word infect come from around 1350. It ultimately comes from the Latin inficere, meaning “to immerse in dye” or “to taint.” Infect, according to any of its meanings, refers to tainting something or someone.
You will hear the word infect often used during outbreaks of disease or during flu season. Microorganisms that cause disease, such as bacteria and viruses, usually reproduce very quickly and are able to spread from one living thing to another. Often, this spread happens when bodily fluids make contact with surfaces and infect them with germs. A healthy person then touches this surface and the germs enter their body and infect them as well. For this reason, medical experts advise practices such as social distancing, cleanliness, and frequent handwashing to try and prevent being infected with a disease.
