A contagious disease is an infectious disease that can be spread rapidly in several ways, including direct contact, indirect contact, and Droplet contact. [1] These diseases are caused by organisms such as parasites, Bacteria, Fungi, and viruses. While many types of organisms live on the human body and are usually harmless, these organisms can ...
Immunocapitalism describes the ways in which disease outbreaks and the acquisition of immunity are leveraged for economic and political gain. The concept highlights the intersection of health, capitalism, and power, demonstrating how social and economic inequalities are exacerbated by epidemics.

An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...
Although contact tracing is most commonly used for control of diseases, it is also a critical tool for investigating new diseases or unusual outbreaks. [10] For example, as was the case with SARS, contact tracing can be used to determine if probable cases are linked to known cases of the disease, and to determine if secondary transmission is ...
People of low SES are both more likely to contract TB and to be more severely affected by the disease. Those with low SES are more likely to be affected by risk factors for developing TB (e.g., malnutrition, indoor air pollution, HIV co-infection, etc.), and are additionally more likely to be exposed to crowded and poorly ventilated spaces.
