What are the 4 stages of infectious diseases?
The natural history of an untreated communicable disease has four stages: stage of exposure, stage of infection, stage of infectious disease, and stage of outcome.
What are the six stages of infection?
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 3 phases of infection process?
The different phases in infections include: Infective period. Communicability period. Incubation period.
What are the 4 stages of pathogenesis?
Stages of Pathogenesis. To cause disease, a pathogen must successfully achieve four steps or stages of pathogenesis: exposure (contact), adhesion (colonization), invasion, and infection.
What are the stages of disease cycle?
The phases of the disease cycle are:
- survival.
- spore germination and infection.
- early root disease development.
- late root disease development.
- spread.
- foliar disease development.
- production of survival structures.
What are the 5 stages of illness behavior?
Suchman, formulated illness behavior as con- sisting of five stages: symptom experience, assumption of the sick role, medical care contact, dependent patient, and recovery or rehabilitation (Table 1-1).
What are the 6 modes of transmission?
The modes (means) of transmission are: Contact (direct and/or indirect), Droplet, Airborne, Vector and Common Vehicle.
What are infectious diseases also known as?
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 are the 5 stages of disease?
The five periods of disease (sometimes referred to as stages or phases) include the incubation, prodromal, illness, decline, and convalescence periods (Figure 2). The incubation period occurs in an acute disease after the initial entry of the pathogen into the host (patient).
What are the 5 stages of pathogenesis?
The stages of pathogenesis include exposure, adhesion, invasion, infection, and transmission.
What is the first stage in the infectious process?
1. Incubation. The incubation stage includes the time from exposure to an infectious agent until the onset of symptoms. Viral or bacterial particles replicate during the incubation stage.
Which is the 5th stage of illness?
Fifth disease is contagious (spread from person to person) in the early stages before symptoms appear. Once the rash appears, it is no longer contagious. It is spread by coughing, sneezing or by touching secretions from the nose and mouth of an infected person.
What are the five stages of disease?
The Six Stages of Disease. There are six different stages that diseases progress through (Accumulation, Aggravation, Overflow, Relocation, Manifestation, and Maturation).
What are the 10 most common infectious diseases?
The 10 most frequently reported nationally notifiable infectious diseases for 1995 were, in descending order, chlamydia, gonorrhea, acquired immunodeficiency syndrome (AIDS), salmonellosis, hepatitis A, shigellosis, tuberculosis (TB), primary and secondary syphilis, Lyme disease, and hepatitis B (2).
What are the stages of disease?
ENERVATION – This is the first step in disease.
What is clinical stage of disease?
clinical disease. a stage in the history of a pathological condition that begins with anatomical or physiological changes that are sufficient to produce recognizable signs and symptoms of a disease.
