What is an example of a droplet transmissible infectious agent?

What is an example of a droplet transmissible infectious agent?

Two examples of droplet transmissible infectious agents are the influenza virus which causes the seasonal flu and Bordetella pertussis which causes pertussis (i.e., whooping cough).

Which diseases is typically spread by droplet transmission?

What are the 3 main ways infection can get into the body?

This is the way that the pathogen enters the body of the potential host. Pathogens can enter the body by coming into contact with broken skin, being breathed in or eaten, coming into contact with the eyes, nose and mouth or, for example when needles or catheters are inserted.

What is the most common method of spreading 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 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.

What are the main routes infection can 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 are the 5 basic modes of transmission of infection?

Modes of transmission

  • Direct. Direct contact. Droplet spread.
  • Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)

How do viruses enter the body?

Humans can become infected by a virus in contaminated food or water. The virus enters the body through the stomach or bowels when the contaminated food or water is swallowed. Viruses spread through food or water often affect the gastrointestinal tract and cause symptoms such as nausea, vomiting, and diarrhea.

How do bacteria make you ill?

But infectious bacteria can make you ill. They reproduce quickly in your body. Many give off chemicals called toxins, which can damage tissue and make you sick. Examples of bacteria that cause infections include Streptococcus, Staphylococcus, and E.

How do you know if viral or bacterial infection?

Bacterial Infections Symptoms persist longer than the expected 10-14 days a virus tends to last. Fever is higher than one might typically expect from a virus. Fever gets worse a few days into the illness rather than improving.

How do you kill bacteria in your body?

Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing. The word antibiotic means “against life.” Any drug that kills germs in your body is technically an antibiotic.

Why do viruses make us feel ill GCSE?

Viruses make us sick by killing cells or disrupting cell function. ... Sometimes they kill cells and tissues outright. Sometimes they make toxins that can paralyze, destroy cells' metabolic machinery, or precipitate a massive immune reaction that is itself toxic.

Why can't drugs that kill bacteria kill viruses?

Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate. The antibiotic has no “target” to attack in a virus. However, antiviral medications and vaccines are specific for viruses.

How does the body kill a virus?

A virus-bound antibody binds to receptors, called Fc receptors, on the surface of phagocytic cells and triggers a mechanism known as phagocytosis, by which the cell engulfs and destroys the virus. Finally, antibodies can also activate the complement system, which opsonises and promotes phagocytosis of viruses.

What is the most common communicable disease?

What are 3 examples of non communicable diseases?

The four main types of noncommunicable diseases include cardiovascular disease, cancer, chronic respiratory disease, and diabetes.

What is communicable and noncommunicable diseases?

Communicable and Non-communicable diseases Typically, it is caused by pathogens such as viruses, bacteria. For instance diseases such as AIDS, malaria, dengue etc. On the other hand, non-communicable diseases are the diseases which are not transmitted from one to another person.

What are two causes of communicable disease?

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 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.
