Terms you should know: Outbreakhttp://www.who.int/csr/don/en/ / (WHO)http://www.cdc.gov/outbreaks/index.html (CDC)http://www.cdc.gov/CDCTV/RespondOutbreaks/index.html (video)October 2012 - strawberries imported from China were thought to be contaminated with norovirus. More than 11,000 students were sickened throughout eastern German, with 32 requiring hospitalization. About 500 schools were involved in the outbreak of this norovirus, which is the leading cause of stomach flu.Transmission?Same as an outbreak except the percentage of overall deaths caused by the disease is higher OR the number infected dramatically increases from one year to the next in an epidemic. Terms you should know: epidemicepidemic of severe acute respiratory syndrome (SARS) in 2003, sickened about 8,098 people and led to about 774 deaths in 29 countries. (Transmission: direct/indirect/possible airborne)Washington State Secretary of Health declared a pertussis (whooping cough) epidemic on April 3, 2012 after a 1,300% increase in cases were reported compared with 2011 . (Transmission: direct/indirect)
A pandemic is a global disease outbreak.Terms you should know: pandemic1918 Spanish Flu (Virus)DNA mutated into something more virulent. particularly deadly in 20 to 35 year olds.First reported case in Kansasestimated up to 40% of the world's population was infected killing 20 to 50 million people. (Transmission: direct/indirect) (Rosenburg 2012)
Review questionsWhat factors may determine if a person who is exposed to a pathogen will actually become ill? Why do outbreaks or epidemics end?Ebola outbreak 2014
Describe the microbe that causes EbolaWhat is the mortality rate? Show your calculations.Why is this considered an outbreak? When did the outbreak start?Why is Ebola primarily found in Africa?What is the transmission vector?Identify the source of the pathogen (ground zero) and describe the mode of transmission. Describe how health care workers protect themselves from exposure to Ebola. Describe what countries are doing to reduce the risk of transmission.
