Yellow fever is a viral hemorrhagic fever transmitted by mosquitoes infected with the yellow fever virus. Yellow fever 
has been a source of several devastating epidemics. Yellow fever epidemics broke out in the 1700s in Italy, France, Spain, England, and the United States.This Guidelines for Yellow Fever Control and Prevention describes how to detect and confirm suspected cases of yellow fever and how to respond to an outbreak of yellow fever and prevent additional cases from occurring.
It is World Health Organization which issued the Guidelines for Yellow Fever Control and Prevention as this guidelines are intended for use at the district level. There are sections such prepare to conduct district level activities for yellow fever (surveillance, identify, collecting specimen etc), detecting yellow fever, confirming yellow fever, and respond to the confirmed outbreak.
Yellow fever known as untreatable, and case fatality rates in severe cases can exceed 50%, according to this guidelines. It is stated and underlined that,
There is high risk for an explosive outbreak in an unimmunized population –and children are
especially vulnerable– if even one laboratory confirmed case of yellow fever occurs in the
population. Effective activities for disease surveillance remain the best tool for prompt
detection and response to an outbreak of yellow fever especially in populations where
coverage rates for yellow fever vaccine are not high enough to provide protection against
yellow fever.
