First of all, let’s get one thing straight: hives is definitely not contagious. You may have heard that it could be contagious, but this may be because of common misconceptions about the skin condition. The truth is, hives is simply an allergic reaction, although at times the allergens are unknown and they could be an indication of an underlying disease. Many people think that hives are contagious because of their appearance-because of the rash-like bumps, itchiness and form that seem to spread across the body, hives can look like a skin disease that is contagious. So how come you hear so many other people saying they are contagious? why is there such a misconception? how is hives contagious?
There are a number of reasons why people ask, how is hives contagious? in a way, hives is considered contagious because their TRIGGERS can be contagious. This might sound confusing at first, but just take note that triggers are simply the cause of the allergic reaction (in this case, hives). for instance, bacteria can carry certain substances that you are actually allergic to. Contagiousness basically refers to how easily the spread of hives is probable form one individual to another. This has nothing to do with inheriting disease from parents or genetics.
Hives are not contagious and a person with the condition does not have to be isolated from others. So are hives contagious? in short, they aren’t. Hives themselves are not contagious, but their triggers could be. Common triggers in this case include bacteria, viruses and parasites.
