Infectious Diseases are generally caused by microbes called pathogens that enter into the body and prevents it from functioning properly. Infections are caused by bacteria, which can be airborne or blood-borne, or from viruses, which are typically airborne or by contact with a carrier or fomite. (A fomite is an object upon which viruses or bacteria can live for a short period of time.)
Depending on the disease it can be caused by any of the following types of infectious organisms: bacteria, fungi, protozoa, parasites, rickettsia, viruses. It is also believed that certain types of defective proteins called prions, although they are not organisms, are the cause of some infectious diseases.
Causes of infectious disease
Generally may been caused by normal skin flora or by exogenous bacteria, in most cases occurred on area where skin was previously broken (cuts, blisters, burns, cracks in the skin, surgical wounds ,sites of intravenous catheter insertion or other causes this type).
Example - Cellulitis disease
Probably the most usual cellulitis causes in adults with no particular medical complications is group A streptococcus. This bacteria is common on the skin and in the throat of every person and generally most ordinarily causes of cellulitis.
Second usual cause by grownups is Staphylococcus aureus (S. aureus). This bacteria is commonly found on person's skin and lining of mouth and nose (medically mucosa).In special cases, cellulitis causes may been of other bacteria type. When this cellulitis causes happen , usually it's the result of medical condition like HIV,Diabetes or AIDS, or because infection affected a very specific body area - other causes of cellulitis.
Infectious diseases are caused by viruses, parasites, bacteria, and fungi. Infectious diseases can spread from person to person or from animal to human.
Certain pathogens enter and multiply within the human body.. (:

How is an infectious disease different from an noninfectious disease?
Infectious diseases involve a causative organism, from groups such as bacteria, viruses, fungi, and such. Noninfectious diseases involve causes other than specific infectious organisms.
Does a toxin cause infectious diseases?
Not directly, but the infectious microorganism that causes the disease may produce a toxin that is the cause of some of the disease's symptoms. Not every disease causing microorganism produces a toxin.
