In December 2015, the World Health Organization held a workshop on prioritization of pathogens "for accelerated R&D for severe emerging diseases with potential to generate a public health emergency, and for which no, or insufficient, preventive and curative solutions exist." [46] The result was a list containing the following six diseases:
WHO fungal priority pathogens are groups of pathogenic fungi that the World Health Organization deems in need of global attention. [1] [2] [3] [4]
One Health is at the intersection of human health, animal health, and environmental health. [1]One Health is an approach calling for "the collaborative efforts of multiple disciplines working locally, nationally, and globally, to attain optimal health for people, animals and our environment", as defined by the One Health Initiative Task Force (OHITF).

The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
[61] [62] In 2021, pathogen researchers reported the development of machine learning models for genome-based early detection and prioritization of high-risk potential zoonotic viruses in animals prior to spillover to humans which could be used for virus surveillance for (i.a.) measures of "early investigation and outbreak preparedness" and ...
Colored scanning electron microscope (SEM) image of SARS-CoV-2, speculated in 2020 as being the first virus to create Disease X [1] [2] [3]. Disease X is a placeholder name that was adopted by the World Health Organization (WHO) in February 2018 on their shortlist of blueprint priority diseases to represent a hypothetical, unknown pathogen.
Scientific Advisory Group for Origins of Novel Pathogens (or SAGO) [1] [2] [3] is a permanent advisory body of the World Health Organization, formed in July 2021, with a broad objective to examine emerging infectious diseases, including COVID-19.
Once a pathogen has been associated with an illness, researchers have reported difficulty displacing these pre-existing theories. [3] [4] 3. Variable pathogenicity: Infection with pathogens can produce varying responses in hosts, complicating the process of showing a relationship between infection and the pathogen. [5]
