Two main causes of disease are immediate cause and contributory cause.
Immediate cause: This is due to the organisms that enter our body and cause disease.
Example, virus, protozoa, bacteria.
Contributory cause: These are the secondary factors which lead these organisms to enter our body.
Example, dirty water, unclean surrounding, contaminated food etc.
