Invasive Meningococcal Disease can be described as, “inflammation around the brain and spinal cord (the meninges). (Oregon Department of Health 2009) It is caused by a bacterium called Neisseria meningitidis that lives in noses and throats. The disease occurs when the bacterium spreads throughout the body via blood stream after penetrating the mucous membranes of the nose and throat. In the journal Modifiable Risk Factors for Invasive Meningococcal Disease during an Edmonton Alberta Outbreak, 1999-2002, Lance Honish as well as several other authors did a case study on “an outbreak of invasive meningococcal disease (IMD) in metro Edmonton Alberta, Canada.” (Honish 2008) The journal’s case study is based on the outbreak of invasive meningococcal disease between the months of December of 1999 to June 2002. The disease was caused by a “bacterial infection called Neisseria meningitidis and was spread though direct contact or inhalation of respiratory droplets.” (Honish 2008) There was a total of eighty-four laboratory confirmed cases between the ages of below five to late seventies. All together, there were a total of one-hundred and thirty-two participants that had to meet diagnostic criteria: isolation of N. meningitidis from normally sterile sites, demonstration of N. meningitidis antigen in blood or cerebrospinal fluid (CSF), or positive N. meningitidis polymerase chain reaction (PCR) test in blood or cerebrospinal fluid. (Honish 2008) In the study, the method of choice was a case control study. There were two controls that were watched on age and sex. The participants were recruited by random-digit dialing and were administered a telephone questionnaire. Out of the 132 participants, there were forty-four cases and eighty-ei... ... middle of paper ... ...lso, the authors used a large span of age groups starting under the age of five all the way up to the late seventies instead of using just one specific age group. Although the authors used a wide span of age groups, they failed to clearly explain how much a certain variable affected a specific age group. Overall, the findings in the journal can help prevent future outbreaks of invasive meningococcal disease from occurring. Works Cited Honish L, Soskolne C.L, Senthilselvan A, Houston S. 2008 Jan-Feb.
