Study of diseases

  • Detailed clinical descriptions of dysentery, malaria, syphilis and tuberculosis

    Thomas Sydenham proposed the basis to recognize diseases like entities and the current system of classification of diseases.

  • Laws of desease

    They were developed by insurance companies to establish the costs of life insurance.
    Tables were developed by committees selected in Sweden, the Richard Price in England, and Charles Olipahnt in Scotland
  • Prevalence, incidence and duration of diseases

    William Farr discovered the relationship between the prevalence incidence and duration of disease.

    Statistical Methods to investigate the way in which genetic factors are involved in the occurrence of diseases

    Population distribution of genes and their variations that may explain the presence of various diseases is currently investigated with statistical methods.
  • Machine Learning Methods

    Machine-learning techniques emerged in the biomedical sciences and techniques of clinical decision support to improve the sensitivity and specificity in detection and monitoring of disease, increasing objectively the clinical decision-making process.
