An infection is an invasion of the body by microscopic organisms. A pathogen is any agent that can cause a disease. 

 

Pathogens are often carried by “vectors”, from the Latin word vectus, “one who carries”. These are humans, animals, or microbes that carry and transmit a pathogen to others. 

 

Many bacteria are good guys. Some, however, are pathogens and cause infectious diseases, including cholera, syphilis, anthrax, leprosy, and bubonic plague. The most common fatal bacterial diseases affect the lungs, with tuberculosis alone killing about 2 million people a year, mostly in underdeveloped countries. 

 

Examples of common human diseases caused by viruses include the common cold, influenza, chickenpox, rabies, hepatitis, herpes, Ebola, and Zika.

Most diseases of which causes are known with confidence are caused by 
 
infections and parasites
various kinds of trauma - physical trauma, chemical trauma (poisoning)
accidents in development (it almost impossible to construct a human being perfectly and without defects)
the accumulation of damage (this includes most cancers - the cancers of older age). 
 
 
As well as the damage of micro-organisms and parasites, there are problems with the body's 'immune' reactions to these invaders - and these probably cause another whole set of 'autoimmune' diseases; which may include eczema, asthma, rheumatoid arthritis and many of the other diseases that are improved by 'steroids' (glucocorticoids).
