ABSTRACT
The patient zero is the first reported patient in a pandemic within a population, or the first documented patient incorporated in a pandemic study. Some scientists claimed that it’s important to examine primary cases. The term patient zero refers to the person identified as the first carrier of a communicable disease in an outbreak of related cases. They act as a symbol for initial actions that have major downstream consequences.The primary recorded victim of the Ebola infection was a 44 year old teacher named Mabola Lokela,who passed away on 8thSeptember 1970, 614 days after the clinical manifestation started.An infant in the Lewis House at 40 broad Road is viewed as the patient zero in the 1854 cholera outbreak in the Soho neighborhood of London.Pandemic is a disease outbreak that spreads across countries or continents and it affects more people and takes more lives than epidemic.It is an epidemic which takes place on a scale that crosses universal limits, generally influencing individuals on an overall scale. Detection of patient zero gives new insight to epidemiologists about the nature of first transmissions into a population.it’s important to find the first person infected with the pathogen.By knowing person’s history of patient zero we can determine the outbreak of the disease and the route of transmission.Discovering them might be significant in certain occasions, to know whether they are still alive and transmitting the infection. Identifying a “patient zero” is a rife with potential to provoke blame and scapegoating. Patient zero triggers a “desperate hunt” and is continuously giving expression to communal fears about dangerously reckless behaviour,Researchers have found people harbour negative attitudes towards Patient zero.The patient zero issue comprises of finding the source of a pandemic outbreak given,perceptions at a later time.Contemplating the patient zero issue we additionally tackle the issue of finishing and rectifying the observation to people and false test results.
