DirectoryUnderstanding Ranking
Compare the ways in which an exhibition can take place, and then the particular contexts of the catalogue. The categories "several cases" and "body flora" describe mechanisms or contexts: they are not channels of transmission between people.
The numbers below describe our documentary catalogue. They do not measure the frequency of disease, its severity or a health alert.
This path distinguishes the transmission of a mother-to-child infection from the way the mother acquired it. It may occur during pregnancy, at birth or after depending on the agent. A maternal exposure does not prove an infection of the foetus.

Compare and deepen →This section brings together the respiratory tract records. It helps to choose between markers on indoor air, contacts and the protection of fragile people. The agents differ in their infectiousness, symptoms and immunization possibilities.
35 sheets in the catalogue
Compare and deepen →The term "contact" covers several situations: skin, lesions, secretions or contaminated objects depending on the agent. It does not mean that all infections are transmitted by a handshake. The disease sheet shall specify the mechanism to be examined.
46 sheets in the catalogue
Compare and deepen →The fact sheets in this section refer to exposures where blood or certain fluids may occur. The fluid, the inlet route and the skin integrity should be specified. HIV, hepatitis B and hepatitis C do not have the same opportunities for prevention.
8 sheets in the catalogue
Compare and deepen →This documentary entry combines infections whose transmission can be sexual. An infection may be silent; symptoms alone do not allow for choice or interpretation of screening. The relevant samples depend on the exposures and the sites concerned.
6 sheets in the catalogue
Compare and deepen →The section links infections associated with ingestion of water or food and, for some, with the faeces. Water quality, conservation, preparation and contact occur at different stages. A recalled product is verified by its lot, not only by its brand.
33 sheets in the catalogue
Compare and deepen →A vector is an organism that can participate in the transmission of an agent. The presence of a mosquito or tick does not show that an agent is circulating or that an infection has been transmitted. This category links diseases to landmarks on the ground and travel.
27 sheets in the catalogue
Compare and deepen →A zoonose involves a link between animals and humans, but the possible pathways vary: bite, tissues, secretions, foods or vectors depending on the agent. The presence of animals in a medium is not sufficient to identify an exposure.
32 sheets in the catalogue
Compare and deepen →The environment may constitute a reservoir or exposure context. A sample result describes a medium, a method, and a moment; it does not alone demonstrate an infection in a person. The records link the possible path to a real activity.
31 sheets in the catalogue
Compare and deepen →This catalogue label is a documentary context, not a channel of transmission. It brings together sheets whose mechanisms or rarity require a specific reading. The number of entries here is neither an impact nor an alert level.
1 sheets in the catalogue
Compare and deepen →"Flore of the organism" indicates a possible mechanism linked to organizations already present. This label is not a transmission between people. In particular, it helps to understand why an opportunistic infection does not read as a systematic external contagion.
