What disease can be transmitted through saliva?
Glandular fever – also known as the kissing disease.
Glandular fever is the common term for a viral infection called infectious mononucleosis, caused by the Epstein-Barr virus.
The virus is spread through saliva and infection occurs through contact..
What are the two kinds of transmission?
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.
What are 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 are the 4 types of pathogenic bacteria?
A variety of microorganisms can cause disease. Pathogenic organisms are of five main types: viruses, bacteria, fungi, protozoa, and worms.
What are four routes to spread germs?
Five common ways germs are spread:Nose, mouth, or eyes to hands to others: Germs can spread to the hands by sneezing, coughing, or rubbing the eyes and then can be transferred to other family members or friends. … Hands to food: … Food to hands to food: … Infected child to hands to other children: … Animals to people:
How are microorganisms transmitted?
Transmission of microorganisms occurs directly from one person to another by one or more of the following means: droplet contact by coughing or sneezing on another person. direct physical contact by touching an infected person. direct physical contact (usually by touching soil contamination or a contaminated surface)
What is the means of transmission of the pathogen?
Transmission of pathogens can occur by direct contact, through contaminated food, body fluids or objects, by airborne inhalation or through vector organisms.
What are the means of transmission?
The mode (means) of transmission is the route or method of transfer by which the infectious microorganism moves or is carried from one place to another to reach the new host. The modes (means) of transmission are: Contact (direct and/or indirect), Droplet, Airborne, Vector and Common Vehicle. Portal of Entry.
What are the 4 ways infections can be transmitted?
Infectious diseases can spread in a variety of ways: through the air, from direct or indirect contact with another person, soiled objects, skin or mucous membrane, saliva, urine, blood and body secretions, through sexual contact, and through contaminated food and water.
How do infections 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 is the most effective way to prevent infection?
Simply put, yes. Hand washing is the single most effective way to prevent the spread of infections. You can spread certain “germs” (a general term for microbes like viruses and bacteria) casually by touching another person.
What happens when a pathogen enters the body?
The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies. Antibodies attach to an antigen and attract cells that will engulf and destroy the pathogen. The main cells of the immune system are lymphocytes known as B cells and T cells.
What is inhalation transmission?
NIOSH defines aerosols as a suspension of tiny particles or droplets in the air. Aerosol transmission has been defined as person-to-person transmission of pathogens through the air by means of inhalation of infectious particles. Particles up to 100 μm in size are considered inhalable (inspirable).
What are the 5 basic modes of transmission of infection?
Modes of transmissionDirect. Direct contact. Droplet spread.Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)
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 7 pathogens?
Infectious diseases are caused by pathogens, which include bacteria, fungi, protozoa, worms, viruses, and even infectious proteins called prions.
What are the three main 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.
