What are the 4 types of communicable diseases?
West Nile virus.Ebola.
Can humans get STDS from animals?
“Two or three of the major STIs [in humans] have come from animals. We know, for example, that gonorrhoea came from cattle to humans. Syphilis also came to humans from cattle or sheep many centuries ago, possibly sexually”.
What is the difference between vertical and horizontal transmission of infection?
In general, transmission of viruses can occur through two pathways: horizontal and vertical transmission. In horizontal transmission, viruses are transmitted among individuals of the same generation, while vertical transmission occurs from mothers to their offspring.
What does the mode of transmission mean?
A method of transmission is the movement or the transmission of pathogens from a reservoir to a susceptible host. Once a pathogen has exited the reservoir, it needs a mode of transmission to the host through a portal of entry. Transmission can be by direct or indirect contact or through airborne transmission.
In what ways can direct contact with an animal spread disease?
Because of the close connection between people and animals, it’s important to be aware of the common ways people can get infected with germs that can cause zoonotic diseases. These can include: Direct contact: Coming into contact with the saliva, blood, urine, mucous, feces, or other body fluids of an infected animal.
What is the most common route of transmission?
Contact is the most frequent mode of transmission of health care associated infections and can be divided into: direct and indirect. An example of contact transmitted microorganisms is Noroviruses which are responsible for many gastrointestinal infections.
What are the 4 routes of transmission?
Routes of transmissionDirect Contact Transmission. Direct contact transmission occurs through direct body contact with the tissues or fluids of an infected individual. … Fomite Transmission. … Aerosol (Airborne) Transmission. … Oral (Ingestion) Transmission. … Vector-Borne Transmission. … Zoonotic Transmission.
What are the main routes that infection can enter the body?
Microorganisms capable of causing disease—pathogens—usually enter our bodies through the mouth, eyes, nose, or urogenital openings, or through wounds or bites that breach the skin barrier. Organisms can spread—or be transmitted—by several routes.
What are the three types of transmission based precautions?
There are three categories of Transmission-Based Precautions: Contact Precautions, Droplet Precautions, and Airborne Precautions.
What are the 5 modes of transmission?
Modes of transmissionDirect. Direct contact. Droplet spread.Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)
What are the types of disease transmission?
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. Indirect contact transmission occurs when there is no direct human-to-human contact.
What are the 8 modes of transmission?
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 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…
Which animal carries the most diseases?
Toss in a handful of other barnyard diseases, like mad cow and brucellosis, and livestock are far and away the most disease-bearing animals from a human perspective. The danger of mosquitoes reaches beyond malaria. Dengue infects 50 million people per year, while around 500,000 people come down with chikungunya.
Which of the following is an example of a medical condition spread through droplet transmission?
Droplet Precautions—used for diseases or germs that are spread in tiny droplets caused by coughing and sneezing (examples: pneumonia, influenza, whooping cough, bacterial meningitis).
How Viruses are transferred?
Viruses can be transmitted in a variety of ways. Some viruses can spread through touch, saliva, or even the air. Other viruses can be transmitted through sexual contact or by sharing contaminated needles. Insects including ticks and mosquitoes can act as “vectors,” transmitting a virus from one host to another.
What is vehicle transmission of infection?
The term vehicle transmission refers to the transmission of pathogens through vehicles such as water, food, and air. Water contamination through poor sanitation methods leads to waterborne transmission of disease. Waterborne disease remains a serious problem in many regions throughout the world.
What is an example of vehicle transmission?
Common vehicle transmission: Common vehicle transmission refers to transmission through a contaminated source. Examples include food, medication, intravenous fluid, or equipment that transmits infection to multiple hosts.
What is the most efficient mode of parasite transmission?
In conclusion, the efficiency of parasite transmission from one host to another appears to increase with host density for parasites that rely on contact transmission, ingestion by hosts, or vector transmission.
