Abstract :
Dengue is one of the most important emerging diseases of the tropical and sub-tropical
regions, affecting urban areas. In view of this, we study the pattern of suspected dengue
rather than the dengue itself in Mysore district government hospital as Mysore being one of
the dengue endemic districts of India. A total of 736 patients declared as suspected dengue
by the hospital authorities were considered for the study. Data were separated into three
sets based on the year of occurrences and analyzed using Phase technique, Shewhart
technique, C chart, Poisson tests for counts. In Phase I, suspected dengue in 2011 was in
control with the upper control limit at 5. In phase II, there was an upward shift in the process
i.e for 2012 with process mean 2.346 cases per inspection unit. It was very clear from phase
III that the most of the points were above the revised control limits and hence the 2013
process was a highly significant upward shift in process mean of 2013. A preventive care
technique should be given the importance in the region to monitor the situation in future.
