This is a list of the largest known epidemics (including pandemics) caused by an infectious disease.Widespread non-communicable diseases such as cardiovascular disease and cancer are not included.. An epidemic is the rapid spread of disease to a large number of people in a given population within a short period of time. It usually affects a larger area than an outbreak. 133:608–15. ongoing presence of disease within a population. a specialist in the study of outbreaks of disease within a population group, the ongoing presence of a disease within a population or area, a widespread outbreak of an infectious disease within a population, an epidemic that is geographically widespread, produces symptoms for which no physiological or anatomical cause can be identified, an unfavorable response due to prescribed medical treatment, an illness caused by living pathogenic organisms such as bacteria and viruses, a disease acquired in a hospital or clinical setting, disorder caused by a detectable physiological or structural change in an organ. Thus, if ongoing monitoring programs exist, the level of disease or death may be referred to as an epidemic if it exceeds two standard deviations above the mean.

Disease can also affect ongoing conflicts, though it is rarely a deciding factor in their outcomes. Centers for Disease Control and Prevention. These are called mixed epidemics. Given an area where an epidemic outbreak has occurred, our ML model should be able to identify next outbreak prone areas and identify features which contribute significantly in the spread of the outbreak. It peaks again on December 5 and declines until it peaks a third time. In some common-source outbreaks, case-patients may have been exposed over a period of days, weeks, or longer.

Endemic refers to the constant presence and/or usual prevalence of a disease or infectious agent in a population within a geographic area. Outbreaks of zoonotic or vectorborne disease may result from sufficient prevalence of infection in host species, sufficient presence of vectors, and sufficient human-vector interaction. a physician focusing on the general medical care of hospitalized patients is known as a. hospitalist . Our approach will also take into consideration the geography, climate and population distribution of an affected area, as these are relevant features and subtly contribute to epidemic disease dynamics.

For example, in meningococcal infections, an attack rate in excess of 15 cases per 100,000 people for two consecutive weeks is considered an epidemic. (38, 44) If the number of cases during an epidemic were plotted over time, the resulting graph, called an epidemic curve, would typically have a steep upslope and a more gradual downslope (a so-called “log-normal distribution”). During natural disaster like floods and cyclones, ecological changes occur. Am J Epidemiol 1991. In agriculture, however, the level of production often is the outcome of con­cern, not the presence or absence of disease.
