Cows are natural reservoirs of African trypanosomiasis. In infectious disease ecology and epidemiology, a natural reservoir, also known as a disease reservoir or a reservoir of infection, is the population of organisms or the specific environment in which an infectious pathogen naturally lives and reproduces, or upon which the pathogen primarily depends for its survival.
Disease reservoir may refer to: Natural reservoir, the long-term host of the pathogen of an infectious disease; Fomite, any inanimate object or substance capable of ...
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
Malaria is a disease transferred by the female Anopheles mosquito, located predominantly in sub-Saharan Africa and is a long withstanding public health issue. [33] It is a disease that is strongly regulated by climate factors and therefore climate change will have a notable impact on the transmission of the disease.
Health geography is the application of geographical information, perspectives, and methods to the study of health, disease, and health care. Medical geography , a sub-discipline of, or sister field of health geography, [ 1 ] focuses on understanding spatial patterns of health and disease in relation to the natural and social environment.
Epidemics of infectious disease are generally caused by several factors including a change in the ecology of the host population (e.g., increased stress or increase in the density of a vector species), a genetic change in the pathogen reservoir or the introduction of an emerging pathogen to a host population (by movement of pathogen or host).
Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to channel runoff (or stream flow).It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.
The most common way the disease is spread is via arthropod vectors. Ticks involved include Amblyomma, Dermacentor, Haemaphysalis, and Ixodes. [18] Rodents, rabbits, and hares often serve as reservoir hosts, [19] but waterborne infection accounts for 5–10% of all tularemia in the United States, [20] including from aquatic animals such as seals ...
