How do arthropods cause disease?
Arthropods will transmit diseases via their ability to function as hematophagous vectors which is characterized as their ability to feed on blood at some or all stages of their life cycles.
Arthropod vectors include mosquitoes, fleas, sand flies, lice, fleas, ticks and mites..
What are the common methods of transmission of diseases?
Infectious diseases are transmitted from person to person by direct or indirect contact….Indirect contactAirborne transmission. … Contaminated objects. … Food and drinking water. … Animal-to-person contact. … Animal reservoirs. … Insect bites (vector-borne disease)More items…
What is the most common means of transmission of infectious diseases?
Contact transmission is the most common form of transmitting diseases and virus. There are two types of contact transmission: direct and indirect. Direct contact transmission occurs when there is physical contact between an infected person and a susceptible person.
Which infectious disease is transmitted vertically?
Coxsackievirus. Chickenpox (caused by varicella zoster virus) Chlamydia. HIV.
What does vertical transmission mean quizlet?
Vertical transmission. AKA mother to child transmission or perinatal transmission. Vertical transmission. Transmission of the infection from the parental generation to their offspring. This can occur in utero or immediately after birth( ingestion of breast milk or direct contact during or after birth).
Which of the following is an example of horizontal disease transmission?
Examples include acute bacterial infection; viruses such as HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), West Nile virus, and rabies; chronic fungi (e.g., coccidiomycosis, histoplasmosis); and parasites (e.g., Toxoplasma gondii, Strongyloides).
What are the 6 modes of transmission?
Modes of transmissionDirect. Direct contact. Droplet spread.Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)
What are the 3 major portals of entry for disease?
Portals of entry into the human body include:Inhalation (via the respiratory tract)Absorption (via mucous membranes such as the eyes)Ingestion (via the gastrointestinal tract)Inoculation (as the result of an inoculation injury)Introduction (via the insertion of medical devices)
What are the 4 major disease vectors?
Disease vectorsMalaria (protozoan): Anopheles species of mosquito.Lymphatic filariasis (nematode worm): Culex, Anopheles, Aedes species of mosquito.Dengue (virus): Aedes species of mosquito.Leishmaniasis (protozoan): mainly Phlebotomus species of sandfly.More items…
What does horizontal transmission mean?
Horizontal transmission is the transmission of organisms between biotic and/or abiotic members of an ecosystem that are not in a parent-progeny relationship. This concept has been generalized to include transmissions of infectious agents, symbionts, and cultural traits between humans.
What are the 5 basic modes of transmission of infection?
The modes (means) of transmission are: Contact (direct and/or indirect), Droplet, Airborne, Vector and Common Vehicle. The portal of entry is the means by which the infectious microorganisms gains access into the new host.
What is vertical transmission disease?
Vertical transmission refers to generational transmission of viruses from parents to their offspring. HIV-1, e.g., can be acquired in utero (via breaks in the placental barrier or transcytosis of cell-associated virus), during delivery (intrapartum), or via breastfeeding.
