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.

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.
Epstein–Barr virus infectious mononucleosis (Mono) 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 ...
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
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]
In some infectious diseases, the severity of symptoms has been shown to be dependent on specific genetic traits of the host. [6] [7] 4. Organisms that look alike but behave differently: In some cases a harmless organism exists which looks identical to a disease causing organism with a microscope, which complicates the discovery process. [8] 5.
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 ...
