Infectious substances, affecting humans
An infection is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce. An infectious disease is an illness resulting from an infection, and some infectious diseases are also communicable (transmissible). Infections can be caused by a wide range of pathogens, most prominently bacteria and viruses. Hosts can fight infections using their immune systems Wikipedia
