Thank you comment icon Dread disease riders are added to life insurance policies to help cover the costs of a critical illness. Illnesses typically covered include cancer, kidney failure, organ transplant, a stroke, or heart attack. Benefits are usually paid in a lump sum. Person to person. Infectious diseases commonly spread through the direct transfer of bacteria, viruses or other germs from one person to another. This can happen when an individual with the bacterium or virus touches, kisses, or coughs or sneezes on someone who isn't infected.J Alins

Yarek’s Answer

Diseases may be caused by a breakdown in our bodies (like cancer, heart disease, asthma). These might be triggered by some external factor, but often have some genetic part. Some people are just more likely to get one. These don't spread among people (there are exceptions, like cancer caused by viruses).

Diseases may also be caused by infection by a virus, bacteria, fungus, or even (very small) animals. All living things (and "kind of living", like viruses) try to grow and reproduce. In the case of these diseases, the place they grow and reproduce well happens to be in our bodies. Many of these spread to us from our environment, or from animals. Their bodies are a lot like ours, so it's a similar place to live and grow.
