What is the cycle of infection in order?
The six links include: the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. The way to stop germs from spreading is by interrupting this chain at any link.
What are the three phases of infection process?
The different phases in infections include: Infective period. Communicability period.
What is chain of infection?
The means by which an organism transfers from one carrier to another by either direct transmission (direct contact between infectious host and susceptible host) or indirect transmission (which involves an intermediate carrier like an environmental surface or piece of medical equipment). PORTAL OF ENTRY.
Which of the following is the first chain in the chain of infection?
1. The pathogen. The first link in the chain of infection is the infectious agent or pathogen which can take the form of: Viruses – such as Influenza A, shingles and Hepatitis.
What are the five classifications of infectious diseases?
Classification of Infectious Diseases
- Bacterial infectious diseases.
- Viral infectious diseases.
- Parasitic infectious diseases.
- Fungal infectious diseases.
- Mycobacterial diseases.
- Air borne diseases.
- Food borne diseases.
- Water borne diseases.
What are the processes of infection?
The infectious disease process includes the following components: (1) agent (2) reservoir (3) portals of entry and exit (4) mode of transmission (5) immunity.
What are the chains of infection?
The six links in the chain are:
- The Infectious Agent – or the microorganism which has the ability to cause disease.
- The Reservoir or source of infection where the microorganism can live and thrive.
- The Portal of Exit from the reservoir.
- The Mode of Transmission.
- The Portal of Entry.
- The Susceptible Host.
What is the second stage of infection?
The second phase, according to the scientists, is the pulmonary phase (Phase 2), when the immune system becomes strongly affected by infection, and leads to primarily respiratory symptoms such as persistent cough, shortness of breath, and low oxygen levels.
What is transmission of infection?
Transmission occurs when an infected person touches or exchanges body fluids with someone else. This can happen before an infected person is aware of the illness. Sexually transmitted diseases (STDs) can be transmitted this way.
