Transmissibility is the probability of an infection, given a contact between an infected host and a noninfected host. [8] Community transmission means that the source of infection for the spread of an illness is unknown or a link in terms of contacts between patients and other people is missing. It refers to the difficulty in grasping the ...

Infection control addresses factors related to the spread of infections within the healthcare setting, whether among patients, from patients to staff, from staff to patients, or among staff. This includes preventive measures such as hand washing , cleaning, disinfecting, sterilizing , and vaccinating .
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.
Furthermore, the infective ability of the virus must be maintained throughout all these stages. [50] In addition the risk for infection is also dependent on host immune system competency plus the quantity of infectious particles ingested. [41] Antibiotics may be used in dealing with airborne bacterial primary infections, such as pneumonic ...
Coxsackie B virus: Coxsackie B virus infection Enterovirus infection is diagnosed mainly via serological tests such as ELISA and from cell culture. There is no well-accepted treatment for the Coxsackie B group of viruses. Under research [10] PRNP: Creutzfeldt–Jakob disease (CJD) No Crimean-Congo hemorrhagic fever virus Crimean-Congo ...

In other cases, the virus can cause systemic disease through a disseminated infection spread throughout the body. The predominant mode of viral dissemination occurs through the blood or lymphatic system , some of which include viruses responsible for chickenpox ( varicella zoster virus ), smallpox ( variola ), HIV ( human immunodeficiency virus ).
