Named after St. Cyprian, a bishop of Carthage (a city in Tunisia) … Dengue epidemic struck the Capital from mid-August to end-November, 1996, with Dengue Haemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS), the worst ever in India’s history. Common source epidemic is further divided into two types: a) Point source epidemic: It is also known as "single exposure epidemic". Plague of Cyprian: A.D. 250-271. polio vaccine), or food, could result in similar outbreaks. Types of epidemics: Mostly of two types: 1. Types of epidemic Point source - An epidemic in which all cases are infected at the same time, usually from a single source or exposure. A well of contaminated water, or a nationally distributed brand of vaccine (e.g. Two Broad Types of Epidemiology: I descriptive epidemiology: examining the distribution of disease in a population, and observing the basic features of its distribution I analytic epidemiology: investigating a hypothesis about the cause of disease by studying how exposures relate to disease 7/19. Periodic fluctuations 2. Jama 320, 2417–2418.] Epidemics of infectious disease are generally caused by several factors including: Two major types of epidemics may be distinguished. Transmission continues until the number of susceptibles is depleted or susceptible individuals are no longer exposed to infected persons or intermediary vectors. For example, for a disease with a short incubation period (e.g., Bacilius cereus) and cases distributed over a short period of time (hours), the scale for the x-axis may be more meaningful by hour rather than by day. An epidemic of an infectious disease can happen if the virus, bacteria, or other cause of the disease has recently grown stronger, is introduced somewhere it has … Jahrhunderts. Definition and characteristics An epidemic is then unusual increase in the number of cases of an infectious disease which already exists in a certain region or population. Eg., Bhopal gas tragedy in India and Minamata disease in Japan resulting from consumption of fish containing a high concentration of methyl mercury. Outbreaks may also occur following exposure to chemicals or to radioactive materials. Figure 5: Measles in Trentino (Italy), 1949-1999 –750-1,000", "1693 — June 17 start, Yellow Fever, Boston, British fleet arrival from Martinique[1] — <10? To develop effective and timely strategies to cope with the challenges of CVD epidemics, we need to understand the current epidemiological features of the major types of CVD and the implications of these features for the prevention and treatment of CVD. The exposure to the disease agent is brief and essentially simultaneous, the resultant cases all develop within one incubation period of the disease.
