What are three methods of disease transmission?
Infectious diseases are transmitted from person to person by direct or indirect contact….Indirect contactAirborne transmission.
Food and drinking water.
Insect bites (vector-borne disease)More items….
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 are the principles of prevention class 9?
How Can Disease Be Prevented?Hygienic conditions should be maintained in the surroundings we live in. … Safe drinking water should be provided to prevent water-borne diseases.Provide a clean environment which prevents the breeding of mosquitoes.
How can we stop diseases from spreading?
Preventing the Spread of Infectious DiseasesWash your hands often. … Get vaccinated. … Use antibiotics sensibly. … Stay at home if you have signs and symptoms of an infection. … Be smart about food preparation. … Disinfect the ‘hot zones’ in your residence. … Practice safer sex. … Don’t share personal items.More items…
What is the most common mode 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 is the number one mode 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 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 is the impact of disease?
From the medical or disease perspective, patients’ functioning, disability and health are seen primarily as the consequences or the impact of a disease or condition. In this perspective, self-administered health status instruments are used primarily to evaluate the effects of drug treatments or surgical interventions.
What are means of spread of diseases Class 9?
Infectious diseases may spread through variety of ways: – Air-borne diseases, as the name suggests spread through air. This occurs through the droplets released by an infected person during coughing or sneezing. When these droplets are inhaled by another person, he may also get infected.
What are the 5 methods of disease transmission?
The transmission of microorganisms can be divided into the following five main routes: direct contact, fomites, aerosol (airborne), oral (ingestion), and vectorborne. Some microorganisms can be transmitted by more than one route.
What factors contribute to the spread of disease?
Water, sanitation, food and air quality are vital elements in the transmission of communicable diseases and in the spread of diseases prone to cause epidemics. A number of environmental factors influence the spread of communicable diseases that are prone to cause epidemics.
What are the 4 types of disease 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 5 environmental factors?
They include:Exposure to hazardous substances in the air, water, soil, and food.Natural and technological disasters.Climate change.Occupational hazards.The built environment.
What are the two factors that influence disease transmission?
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. A reservoir is a human, another animal, or a non-living thing (such as soil), where the infectious agent normally lives.
What spread means?
1. verb. If you spread something somewhere, you open it out or arrange it over a place or surface, so that all of it can be seen or used easily. She spread a towel on the sand and lay on it. [ VERB noun preposition]
What are the ways of spreading diseases?
Ways infectious diseases spreadthe air as small droplets (droplet spread) or tiny aerosol particles (airborne spread)contact with faeces (poo) and then with the mouth (faeco-oral spread)contact with the skin or mucus membranes (the thin moist lining of many parts of the body such as the nose, mouth, throat and genitals) (contact spread)More items…
What are the 6 modes of transmission?
Modes of transmissionDirect. Direct contact. Droplet spread.Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)
What are vectors Class 9?
A physical quantity, having both magnitude and direction, is referred to as a vector. The addition of two vectors does not follow ordinary algebra. A vector quantity is represented with an arrow over a letter or a boldface letter. Geometrically, it is represented by a line segment, having an arrow at one end.
