Factors associated with containment delay in days using linear regression analysis (n = 95); the covariates controlled for in the linear regression analysis include age, gender, date of diagnosis confirmation, classification of cases (imported vs local), case identification (self-identified vs not) and previous attendance at healthcare services before hospital admission
