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.
What are the principle routes of transmission of nosocomial infections?
Nosocomial infections, that develop as a result of a stay in hospital or are produced by micro-organisms and viruses acquired during hospitalisation may have several different transmission routes:
contact, droplet, air, water, food, or disease vector carrying and transmitting an infectious pathogen, or blood
.
Is mode of transmission by kissing?
Kissing offers many health benefits, but may also transmit a
small number of disease-causing bacteria and viruses
. Bacteria and viruses in the saliva or blood of one person can be spread to another person by kissing. Some diseases are more easily spread than others.
What are the 4 types of communicable diseases?
Some examples of the communicable disease include
HIV, hepatitis A, B and C, measles, salmonella, measles, and blood-borne illnesses
. Most common forms of spread include fecal-oral, food, sexual intercourse, insect bites, contact with contaminated fomites, droplets, or skin contact.
