  • Clinical Infectious Disease Process
    • Incubation Period
      • The interval between exposure to an infectious agent and the appearance of the first symptoms
      • Micro-organism has entered the individual, undergone colonisation and begun multiplying
        • Insufficient numbers to cause symptoms
    • Prodromal stage
      • The appearance of initial symptoms which are often mild including feeling tired and discomfort
      • Pathogen continues to multiply and the host begins to experience general signs and symptoms of illness
      • Typically a result from activation of immune system such as fever, swelling, pain etc
    • Invasion period
      • The pathogen is multiplying rapidly, invading further tissues at site of initial colonisation and other areas
      • Immune and inflammatory responses being triggered
      • Development of symptoms specifically related to the pathogen and symptoms related to inflammatory response
    • Convales-cence period
      • Individuals immune and inflammatory systems have in general successfully removed infectious agent
      • Symptoms decline
      • However the disease may be fatal or enter the latency phase - resolution of symptoms until reactivation at another time
