Association between Day of Illness Prior to Hospital Visit and Risk of Dengue Shock Syndrome in the Upper Southern Thailand
Keywords:Dengue shock syndrome, day of illness prior to hospital visit, upper southern Thailand
This study analyzed secondary data to achieve two study objectives: to describe epidemiology of patients with dengue shock syndrome and to determine an association between day of illness prior to hospital visit and risk of dengue shock syndrome. The study population was patients who were registered in national disease surveillance system (R506) in Thailand from 2009-2018 and resided in seven provinces in upper southern Thailand. Descriptive statistics were used to describe epidemiology of dengue shock syndrome patients. Patients’ characteristics with the highest proportion were males, Thai nationality, 15-24 years age group, and students. More than two-thirds were hospitalized. The number of patients peaked in 2013. Nakhon Si Thammarat province had the highest number of patients. An average day of illness prior to hospitalization was 3.4 days. Factors associated with risk of dengue shock syndrome were determined using logistic regression. The results show that day of illness prior to hospitalization was not associated with risk of dengue shock syndrome. Female and those aged 0-14 years had higher risk of developing dengue shock syndrome. Healthcare provider should place special focus on female patients and patients aged 0-14 years. Likelihood of dengue shock syndrome varied significantly between districts with high concentration in districts of Surat Thani province and nearby districts.
