Epidemiology and medical cost of hospitalization due to rotavirus gastroenteritis among children under 5 years of age in the central-east of Tunisia

Data on the economic burden of rotavirus infection in Tunisia are needed to inform the decision to include rotavirus in routine childhood immunizations. This study aimed to describe the epidemiological profile of rotavirus disease in central-east Tunisia and to estimate its hospital cost. In the first stage - the prospective collection of epidemiological data - we enrolled all patients < 5 years old who were hospitalized for acute diarrhoea at 5 university paediatric departments in central-east Tunisia during the period 2009-2011. Rotavirus was responsible for 65 [23.3%] of the 279 cases enrolled. In the second stage, cost data were collected retrospectively using an activity-based costing method from the medical records of the children who were positively diagnosed with rotavirus. The average cost of care per child was TD 433 [SD 134]. This is a significant economic burden in Tunisia, where a safe and effective vaccine is available but not yet introduced to the immunization schedule

[Epidemiology of Haemophilus influenzae b meningitis in Tunisia]

The incidence of Haemophilus influenzae b meningitis [Hib] in children < 5 years in Tunisia was studied through a surveillance system set up in June 2000 and followed for 14 months. Population-based surveillance began in 3 governorates and sentinel surveillance in 2. Children < 5 years suspected of meningitis had lumbar puncture, macroscopic exam, blood count, chemical analysis and culture carried out. In the 14 months, 80 cases of meningitis were recorded. From the population-based surveillance most cases were children < 1 year [73.6%] and boys [64%]. H. influenzae was isolated in 38% of cases, pneumococci in 13% and meningococci in 7%. The incidence of confirmed Hib was 14.4/100 000 children. The estimated cost of identifying and treating Hib meningitis and its complications was greater than the cost of vaccine introduction. Based this study, the Ministry of Health has decided to introduce Hib vaccination
