Abstract
The aim of this study was to estimate the economic burden of typhoid fever in Pemba, Zanzibar, East
Africa. This study was an incidence-based cost-of-illness analysis from a societal perspective. It covered new
episodes of blood culture-confirmed typhoid fever in patients presenting at the outpatient or inpatient
departments of three district hospitals between May 2010 and December 2010. Cost of illness was the sum
of direct costs and costs for productivity loss. Direct costs covered treatment, travel, and meals. Productivity
costs were loss of income by patients and caregivers. The analysis included 17 episodes. The mean age
of the patients, was 23 years (range=5-65, median=22). Thirty-five percent were inpatients, with a mean of
4.75 days of hospital stay (range=3-7, median=4.50). The mean cost for treatment alone during hospital
care was US$ 21.97 at 2010 prices (US$ 1=1,430.50 Tanzanian Shilling─TSH). The average societal cost was
US$ 154.47 per typhoid episode. The major expenditure was productivity cost due to lost wages of
US$ 128.02 (83%). Our results contribute to the further economic evaluation of typhoid fever vaccination
in Zanzibar and other sub-Saharan African countries.
