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.

Everything can spread diseases. What, 'which' are you concerned about?

Most diseases are spread by germs.
Influenza and the common cold can be spread by air, among other routes.
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
Using the term "transmission" is more accurate because it includes all possible mechanisms by which diseases can be spread, such as through air, water, or vector-borne routes, not just exclusively person-to-person. It also helps to convey the idea that diseases can be transmitted in various ways beyond direct contact between individuals.
Some charities have been giving grants to help prevent the spread of the diseases.
