Infectious diseases with high prevalence are listed separately (sometimes in addition to their epidemics), such as malaria, which may have killed 50–60 billion people throughout history, or about half of all humans that have ever lived.

A zoonosis is an infectious disease of humans caused by a pathogen that can jump from a non-human host to a human. [35] Major diseases such as Ebola virus disease and salmonellosis are zoonoses. HIV was a zoonotic disease transmitted to humans in the early part of the 20th century, though it has now evolved into a separate human-only disease. [36]
Diagnostic modalities for infectious mononucleosis include: Person's age, with highest risk at 10 to 30 years. Medical history, such as close contact with other people with infectious mononucleosis; Physical examination, including palpation of any enlarged lymph nodes in the neck, or enlarged spleen.
The Red Cross plays a key role in providing emergency medical relief in war-torn areas, and its work helps contains the spread of infectious disease in these environments. [23] Switzerland 1880: Discovery: Microorganisms responsible for malaria are identified by Charles Louis Alphonse Laveran. They belong to the genus Plasmodium, and their over ...
Over the past 50,000–100,000 years, as modern humans increased in numbers and dispersed throughout the world, new infectious diseases emerged, including those caused by viruses. [1] Earlier, humans lived in small, isolated communities, and most epidemic diseases did not exist.
An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection. Infections can be caused by a wide range of pathogens , most prominently bacteria and viruses . [ 2 ]
Epidemics of infectious disease are generally caused by several factors including a change in the ecology of the host population (e.g., increased stress or increase in the density of a vector species), a genetic change in the pathogen reservoir or the introduction of an emerging pathogen to a host population (by movement of pathogen or host).
