In epidemiology, a disease vector is any living [1] agent that carries and transmits an infectious pathogen such as a parasite or microbe, to another living organism. [ 2 ] [ 3 ] Agents regarded as vectors are mostly blood-sucking insects such as mosquitoes.
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 ...
Sandfly species transmit the disease leishmaniasis, by acting as vectors for protozoan Leishmania species, and tsetse flies transmit protozoan trypansomes (Trypanosoma brucei gambiense and Trypansoma brucei rhodesiense) which cause African Trypanosomiasis (sleeping sickness). Ticks and lice form another large group of invertebrate vectors.
A fomite (/ ˈ f oʊ m aɪ t /) or fomes (/ ˈ f oʊ m iː z /) is any inanimate object that, when contaminated with or exposed to infectious agents (such as pathogenic bacteria, viruses or fungi), can transfer disease to a new host. [1]
Asymptomatic carriers can be categorized by their current disease state. [5] When an individual transmits pathogens immediately following infection but prior to developing symptoms, they are known as an incubatory carrier. Humans are also capable of spreading disease following a period of illness.
Drugs, heart disease, vehicle fumes contributed to Floyd’s death, defense expert testifies in Derek Chauvin trial. Nelson Oliveira. April 14, 2021 at 1:10 PM.
The causes listed are relatively immediate medical causes, but the ultimate cause of death might be described differently. For example, tobacco smoking often causes lung disease or cancer, and alcohol use disorder can cause liver failure or a motor vehicle accident.
