What are the modes of transmission of infectious disease?

What are the modes of transmission of infectious disease?

The mode of transmission can include direct contact, droplets, a vector such as a mosquito, a vehicle such as food, or the airborne route. The susceptible host has multiple portals of entry such as the mouth or a syringe.

What are the 5 portals of entry?

Portals of entry into the human body include inhalation, absorption (via mucous membranes, eyes or naughty bits), ingestion (via the gastrointestinal tract), inoculation (as the result of puncture or trauma) or introduction (insertion of medical devices).

What are the main routes of entry of infection into the body?

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 are the five key ways in which infection can spread?

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 can you prevent infection from spreading?

Preventing the Spread of Infectious Diseases

1. Wash your hands often.
2. Get vaccinated.
3. Use antibiotics sensibly.
4. Stay at home if you have signs and symptoms of an infection.
5. Be smart about food preparation.
6. Disinfect the ‘hot zones’ in your residence.
7. Practice safer sex.
8. Don’t share personal items.

What is the infectious disease?

Infectious diseases are disorders caused by organisms — such as bacteria, viruses, fungi or parasites. Many organisms live in and on our bodies. They’re normally harmless or even helpful. But under certain conditions, some organisms may cause disease. Some infectious diseases can be passed from person to person.

What are the two approaches to treat an infectious disease?

Treatment depends on which microorganism causes the infection.

• If bacteria cause a disease, treatment with antibiotics usually kills the bacteria and ends the infection.
• Viral infections are usually treated with supportive therapies, like rest and increased fluid intake.

What are the two basic principles of prevention of infectious disease?

Hygienic conditions should be maintained in the surroundings we live in. There should be limited exposure to airborne microbes by providing not so crowded living conditions. Safe drinking water should be provided to prevent water-borne diseases. Provide a clean environment which prevents the breeding of mosquitoes.

What are the principles of infection control?

• Introduction.
• The general principles of infection prevention and control.
• Hand hygiene.
• Using personal protective equipment.
• Safe handling and disposal of sharps.
• Safe handling and disposal of chemical waste.
• Managing blood and bodily fluids.

What are the three limitations of dealing with infectious disease?

Answer: The three limitations are: (1) If someone has a disease, their body functions are damaged and may never recover completely. (2) As the treatment will take time, the person suffering from a disease is likely to be bedridden for some time.

What are principles of treatment?

There are primarily two ways to treat a disease: 1. Reduce the effect of the disease: Medicines are provided to reduce the pain or bring down the fever. In other words, symptomatical treatment may help to reduce the impact of a disease, but it might not outright cure it.

What is the basic principle of immunization?

Process. The basic theory of immunization is that the body begins to produce antibodies against it upon administration of the vaccine so that the individual is safe from disease.

What are the general principles of prevention?

The General Principles of Prevention are set out in descending order of preference as follows:

• Avoid risks.
• Evaluate unavoidable risks.
• Combat risks at source.
• Adapt work to the individual, especially the design of places of work.
• Adapt the place of work to technical progress.

What are the ways to treat an infectious disease Class 9?

1. Specific method.
2. General method:
3. To kill the cause of the disease. By taking suitable antibiotics and drugs which kill the disease causing microbes.
4. To reduce the effects of the diseases. By taking medicines to bring down the effects of the disease like fever, pain, etc.

What are the two ways of treatment?

Understanding Different Types of Treatments

• Watch and wait.
• Chemotherapy or other drug therapies.
• Radiation therapy.
• Immunotherapy.
• Vaccine therapy.
• Stem cell transplantation.
• Blood transfusion.
• Palliative care.

How is prevention better than cure?

There are certain diseases that can not be treated so the prevention is better than cure. When someone is ill, person body functions get weakened and can never fully recover. It takes time to cure a disease and the person is likely to be in bedridden for some time, even though adequate care is provided to him.

How do you define disease?

Disease, any harmful deviation from the normal structural or functional state of an organism, generally associated with certain signs and symptoms and differing in nature from physical injury. A diseased organism commonly exhibits signs or symptoms indicative of its abnormal state.

How do you treat diseases?

The person will always have the condition, but medical treatments can help to manage the disease. Medical professionals use medicine, therapy, surgery, and other treatments to help lessen the symptoms and effects of a disease. Sometimes these treatments are cures — in other words, they get rid of the disease.
