Various portals of entry for infectious agents and diseases associated with each portal. Introduction: Diseases and infections are caused when the pathogens enter the body and overtake the immune system. These pathogens enter the body by direct and indirect means. There are several portals through which these pathogens can enter the body. The pathogens are generally microbes such as bacteria, viruses, fungi , and protozoans.
