Dengue fever has become the second most prevalent mosquito borne infection after malaria, causing epidemics
with high mortality. The fatality rate due to dengue shock syndrome (DSS), the most severe form of dengue disease may be
reduced to as low as <0.2% with careful management. Understanding the risk factors for progression to severe dengue and
death is essential in determining triage and management algorithms.
All patients admitted in Christian Medical College Hospital, Ludhiana, with the diagnosis of dengue fever during
August-November 2013 were studied. Information of various demographic parameters, clinical and laboratory findings,
details of treatment and patient outcomes were obtained from the medical records of the hospital, and compared between the
survivors and the dead to identify risk factors for mortality. The data was entered in Microsoft excel spreadsheet and analyzed
in Epi-Info software. Apart from percentages, Odd?s ratio and their 95% CI was calculated.
306 cases of dengue fever were admitted of which there were 40 deaths (13.1%). Age was a significant risk factor for
mortality due to the disease, being highest in the elderly and in those with hypertension. We found higher risk of mortality in
those having diarrhea. Leukocytosis, SGOT and SGPT >1000 and low serum albumin were significant risk factors.
All suspected dengue cases must be confirmed by ELISA tests and case fatality may be reduced with careful
management. There should be increase notification of the disease.
