An organism that infects its host with disease is referred to as a pathogen, and the severity of the disease symptoms is referred to as virulence. Pathogens include viruses, bacteria, unicellular and multicellular eukaryotes, as well as other taxonomically diverse organisms. Pathogens, such as bacteria that are targeted by specialist viruses known as phages, impact every living thing. There are a startling amount of bacteria and viruses on the planet, and they live in almost every habitat. A litre of surface saltwater normally has 100 billion viruses and more than ten billion bacteria. According to estimates, there are 1031 viruses on Earth, or about ten billion times as many as there are stars in the universe. Although the average person has roughly 30 trillion cells, they also have a similar amount of bacteria, largely in their stomach.

On us, inside of us, and all around us are microbes. They live almost everywhere on the world and outnumber human cells in the average person's body, primarily in the gut. The great majority of microorganisms are completely safe for us, and many of them are vital to the health of people, animals, and plants. Others, however, have a variety of harmful effects on their hosts and are either obligatory or facultative pathogens. Up until recently, infectious illnesses accounted for the majority of deaths among people, greatly outpacing those caused by famines or wars. Infectious illnesses have affected human evolution, demographics, migrations, and history since the beginning of time.

Pathogens that are facultative are ones for which the host is only one of the niches available for reproduction. The majority of environmental bacteria and fungi that infrequently cause illness are considered facultative pathogens. Many of the troublesome hospital-acquired microorganisms contributing to the antibiotic resistance pandemic are among them. It is often possible to distinguish between incidental and facultative pathogens, with the latter category including those that only sporadically infect vulnerable or immunocompromised hosts. Neisseria meningitidis and Escherichia coli are typical instances of "accidental" pathogens. Obligate pathogens must complete their life cycle in a host. All viruses are obligatory pathogens because they must reproduce inside the cells of their hosts, making them all pathogens. Obligate pathogens include bacteria, such as the agents that cause syphilis and TB, protozoans and macroparasites.

The intricacy of human interactions with disease-causing agents is thus as important now as it has ever been, despite the global health narrative supporting a decrease in the number of fatalities brought on by infectious diseases. which continue to be a major cause of mortality worldwide. The majority of these deaths are theoretically preventable.
