Different points of view will give you different answers. Commonly we think of disease as bacteria or harmful pathogens or free radicals entering the body, causing a disruption in homeostasis (body's ability to maintain balance). Another viewpoint will tell you those bacteria, pathogens, free radicals, etc, were always there, however a compensatory pattern in lifestyle (i.e.too much coffee, soda, fatty foods leads to acidosis of the blood, causing numerous common problems) has caused an imbalance, physically, emotionally or mentally, and thus providing an environment that the disease can flourish.
Diseases are called by pathogens. These can be bacterias, viruses, protists, fungi, or parasites.
Disease causing microorganisms and body's immune system.
Many things can cause disease including but not limited to bacteria, viruses, parasites, toxins, injury, accidents, and stress. Each may cause disease via a different mechanism which could be a topic for a new question.
The question is very broad, because there are many causes of diseases, including:
Or internal causes such as some hereditary factor.
Diseases are bacteria that multiply very fast,,, and the body tries to combat with its immune system, sometimes when the body has been overburdened by lack of sleep, improper nutrition, and general un hygenic practices will cause germs to spread, multiply, and wreaking havoc. For the most part if you stay generally healthy, and wash your hands etc. the bodys immune system will recognize the threat of infection and therefore send the white blood cells to the rescue.
Air born viruses Germic viruses sneezing , coughing ect
Diseases are formed when your body immune system fails to combat the infectious bacteria or virus .
Mostly by not washing hands.

Infectious diseases are caused by germs, such as viruses, bacteria, and parasites. Contagious or communicable diseases are those that can be spread from one person to another. Infectious diseases that commonly occur among children are often communicable or contagious and may spread very easily from person to person
