Infectious vs. Infective: Difference and Comparison
Edited by Muazma Batool — By Muneeza Rehman — Updated on September 26, 2023
"Infectious" refers to diseases or agents likely to spread to others, while "infective" pertains to the ability to cause infection.
Difference Between Infectious and Infective
"Infectious" and "infective" are terms often associated with diseases and pathogens. Both relate to infections, but they are used slightly differently. "Infectious" typically describes diseases or agents that can be transmitted from one individual to another. When a disease is called infectious, it suggests that there's potential for it to spread, be it through air, water, or direct contact. A person suffering from an infectious disease might be a risk to others if precautions aren't taken.

"Infective", however, zooms in on the ability of an agent to establish an infection. It doesn't necessarily indicate that the disease or condition will spread to others. Instead, "infective" speaks to the capability of a pathogen, be it a bacterium, virus, or another microorganism, to enter a host and cause an infection. For instance, an infective agent might be present in a wound, but it doesn't mean the wound's condition will transfer to another person.

A point to note is the common use of "infectious" in colloquial language. Beyond the realm of medicine, "infectious" can also describe things that metaphorically "spread" – like an infectious laugh. "Infective" doesn't share this broader usage and remains strictly within the confines of medical contexts.

In essence, while both "infectious" and "infective" deal with infections and their causes, "infectious" leans more towards the transmission aspect, highlighting the spreadability of a disease, whereas "infective" underscores the potential of an agent to instigate an infection.
