why are diseases always negative? Are there diseases that have positive effects on human beings?
In: Biology
Diseases are essentially a very broad umbrella term for something going wrong with the body.
Cancer is a disease, as an example, but it’s not typically caused by pathogens (viruses and bacteria- although sometimes it is). It’s instead the result of one of your body’s natural processes, cell division, going wrong.
Diseases are by definition something going wrong with your body. Cell division is not a disease, until it goes out of control and causes cancer.
Likewise, many viruses and bacteria are not considered diseases until they cause some harm to your body. Everyone, for example, has e coli in their gut.
But it doesn’t always cause issues. When it does, they have the disease caused by e. Coli.
