  2. Progression-free survival - Wikipedia

    en.wikipedia.org/wiki/Progression-free_survival

    Progression-free survival (PFS) is "the length of time during and after the treatment of a disease, such as cancer, that a patient lives with the disease but it does not get worse". [1] In oncology, PFS usually refers to situations in which a tumor is present, as demonstrated by laboratory testing, radiologic testing, or clinically. Similarly ...

  3. Latent period (epidemiology) - Wikipedia

    en.wikipedia.org/wiki/Latent_period_(epidemiology)

    In epidemiology, particularly in the discussion of infectious disease dynamics (modeling), the latent period (also known as the latency period or the pre-infectious period) is the time interval between when an individual or host is infected by a pathogen and when that individual becomes infectious, i.e. capable of transmitting pathogens to ...

  4. Infectious period - Wikipedia

    en.wikipedia.org/wiki/Infectious_period

    In epidemiology, particularly in the discussion of infectious disease dynamics (mathematical modeling of disease spread), the infectious period is the time interval during which a host (individual or patient) is infectious, i.e. capable of directly or indirectly transmitting pathogenic infectious agents or pathogens to another susceptible host ...

  5. Survival rate - Wikipedia

    en.wikipedia.org/wiki/Survival_rate

    Survival rate is a part of survival analysis.It is the proportion of people in a study or treatment group still alive at a given period of time after diagnosis. It is a method of describing prognosis in certain disease conditions, and can be used for the assessment of standards of therapy.

  6. Progressive disease - Wikipedia

    en.wikipedia.org/wiki/Progressive_disease

    Not all chronic diseases are progressive: a chronic, non-progressive disease may be referred to as a static condition. Progressive disease can also be a clinical endpoint i.e. an endpoint in a clinical trial. A progressive disease should not be confused with a terminal disease, the difference being that a terminal disease invariably leads to death.

    en.wikipedia.org/wiki/WHO_Disease_Staging_System...

    Following infection with HIV, the rate of clinical disease progression varies enormously between individuals. Many factors such as host susceptibility and immune function, [2] [3] [4] health care and co-infections, [5] [6] [7] as well as factors relating to the viral strain [8] [9] may affect the rate of clinical disease progression.

  8. Incubation period - Wikipedia

    en.wikipedia.org/wiki/Incubation_period

    In a typical infectious disease, the incubation period signifies the period taken by the multiplying organism to reach a threshold necessary to produce symptoms in the host. While latent or latency period may be synonymous, a distinction is sometimes made whereby the latent period is defined as the time from infection to infectiousness.

  9. Prognosis - Wikipedia

    en.wikipedia.org/wiki/Prognosis

    Prognosis (Greek: πρόγνωσις "fore-knowing, foreseeing"; pl.: prognoses) is a medical term for predicting the likelihood or expected development of a disease, including whether the signs and symptoms will improve or worsen (and how quickly) or remain stable over time; expectations of quality of life, such as the ability to carry out daily activities; the potential for complications and ...
