What is vector borne transmission of disease?
Vector-borne diseases are infections transmitted by the bite of infected arthropod species, such as mosquitoes, ticks, triatomine bugs, sandflies, and blackflies.
Arthropod vectors are cold-blooded (ectothermic) and thus especially sensitive to climatic factors..
What are the 10 communicable diseases?

What diseases are carried in body fluids?
Examples of diseases spread through blood or other body fluids:hepatitis B – blood, saliva, semen and vaginal fluids.hepatitis C – blood.human immunodeficiency virus (HIV) infection – blood, semen and vaginal fluids, breastmilk.cytomegalovirus (CMV) infection – saliva, semen and vaginal fluids, urine, etc.More items…
What are the main causes of communicable diseases?
Overview. Communicable, or infectious diseases, are caused by microorganisms such as bacteria, viruses, parasites and fungi that can be spread, directly or indirectly, from one person to another. Some are transmitted through bites from insects while others are caused by ingesting contaminated food or water.
What is the most common communicable disease?
The 5 Most Common Infectious DiseasesHepatitis B. According to current statistics, hepatitis B is the most common infectious disease in the world, affecting some 2 billion people — that’s more than one-quarter of the world’s population. … Malaria. … Hepatitis C. … Dengue. … Tuberculosis.
What is the meaning of communicable diseases?
Communicable diseases, also known as infectious diseases or transmissible diseases, are illnesses that result from the infection, presence and growth of pathogenic (capable of causing disease) biologic agents in an individual human or other animal host.
What is the most common mode of transmission for infection?
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 various modes of transmission?
Pathogens may be transferred from the source to a host by direct or indirect contact transmission and by respiratory transmission. Respiratory transmission may result from inhalation of droplets; or from inhalation of droplet nuclei, i.e., airborne transmission.
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.
What is the difference between communicable and contagious?
A communicable disease is a contagious one. The effect is external. If someone catches the illness, they can get sick and spread the pathogen—be it a cold, virus, or some other disease-causing agent—onto the next person. This can lead to small, isolated outbreaks or full-scale pandemics.
What are the 3 major portals of entry for disease?
The portal of entry 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)
What are the 4 types of communicable diseases?
Communicable diseasesInfluenza. Norovirus. Mumps. Tuberculosis.Pertussis. Zika virus. West Nile virus.Ebola. Chikungunya virus. Coronavirus (COVID-19)
What are 3 ways in which diseases 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.
What does mode of transmission mean?
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.
How many types of communicable diseases are there?
Types and symptoms. Four main types of pathogens cause infection: Viruses, bacteria, fungi, and protists.
What are the 10 non communicable diseases?
Alzheimer’s Disease.Cancer.Epilepsy.Osteoarthritis.Osteoporosis.Cerebrovascular Disease (Stroke)Chronic Obstructive Pulmonary Disease (COPD)Coronary Artery Disease.More items…
What are the different mode of transmission of communicable diseases?
physical contact with an infected person, such as through touch (staphylococcus), sexual intercourse (gonorrhea, HIV), fecal/oral transmission (hepatitis A), or droplets (influenza, TB) contact with a contaminated surface or object (Norwalk virus), food (salmonella, E.
What are the six modes of transmission for communicable disease?
Infectious agents include helminths, protozoa, bacteria, viruses and fungi. Six factors are involved in the transmission of communicable diseases: the infectious agent, the reservoir, route of exit, mode of transmission, route of entry, and the susceptible host.
