    Background In the Mediterranean and Black Sea Region, arbovirus infections are emerging infectious diseases. Their surveillance can benefit from one health inter-sectoral collaboration; however, no standardized methodology exists to study One Health surveillance. Methods We designed a situation analysis study to document how integration of laboratory/clinical human, animal and entomological surveillance of arboviruses was being implemented in the Region. We applied a framework designed to assess three levels of integration: policy/institutional, data collection/data analysis and dissemination. We tested the use of Business Process Modelling Notation (BPMN) to graphically present evidence of inter-sectoral integration. Results Serbia, Tunisia and Georgia participated in the study. West Nile Virus surveillance was analysed in Serbia and Tunisia, Crimea-Congo Haemorrhagic Fever surveillance in Georgia. Our framework enabled a standardized analysis of One Health surveillance integration, and BPMN was easily understandable and conducive to detailed discussions among different actors/institutions. In all countries, we observed integration across sectors and levels except in data collection and data analysis. Data collection was interoperable only in Georgia without integrated analysis. In all countries, surveillance was mainly oriented towards outbreak response, triggered by an index human case. Discussion The three surveillance systems we observed prove that integrated surveillance can be operationalized with a diverse spectrum of options. However, in all countries, the integrated use of data for early warning and inter-sectoral priority setting is pioneeristic. We also noted that early warning before human case occurrence is recurrently not operationally prioritized

    We aimed to compare the efficiency of the first dose of Hepatitis B (HB) vaccine: at Birth versus at 3 months and to evaluate the efficacy of HB vaccine. We conducted a cohort study in the governorate of Monastir. Vaccinated Cohort (VC) included populations receiving the first dose at 3 months (Protocol 1), and at birth (HepB-BD) (Protocol 2). First dose was followed by at least two doses. We collected, from January 2000 to December 2017, cases diagnosed by serological markers (hepatitis B surface antigen (HBsAg) and anti-HBc). We calculated Absolute Risk (AR) per 100,000 PY and the Relative risk reduction (RRR). Twenty-five cases were notified among VC and 1501 cases among not vaccinated cohort (NVC). Twenty- three cases were notified among the cohort receiving the first dose at 3 months and two cases in Protocol 2. The AR per 100,000 PY was 5.67 (CI95%: 3.36–7.99) in Protocol 1 and 0.11 (CI95%: 0.001–0.26) in Protocol 2. The RRR was 77% (95% CI: 66; 85) in Protocol 1 and 99.4% (95% CI: 97.8; 99.9) in Protocol 2. We identified 4 HB cases for children aged between 5 and 11 who benefited from protocol 1 (born between 2000 and 2006) and zero cases for children of the same age group benefiting from protocol 2 (born between 2011 and 2017). The annual number of HB has decreased from 112 in 2000 to 48 in 2017. We predicted 40 new cases of HB in 2030. HepB-BD was 99.4% effective at preventing HB. The continuity of HepB-BD worldwide would achieve WHO‘s goal of eliminating HB as a threat to health by 2050.

    We aimed to describe incidence, trends of tuberculosis (TB) over 18 years and to evaluate the impact of the BCG vaccine after four decades of immunization program according to three protocols. We performed a cohort study including declared cases in Monastir from January 1, 2000 to December 31, 2017. We reported 997 cases of TB. The predominant site was pulmonarylocalization (n = 486). The age standardized incidence of pulmonary and lymph node TB per 100,000 inh were 5.71 and 2.57 respectively. Trends were negative for pulmonary TB (PTB) (b = - 0.82; r = -0.67; p<10-3) and positive for lymph node localization (b = 1.31; r = 0.63; p<10-3). We had not notified cases of HIV associated with TB. Crude incidence rate (CIR) of PTB per 100,000 inh was 8.17 in Non-Vaccinated Cohort (NVC) and 2.85 in Vaccinated Cohort (VC) (p < 0.0001). Relative risk reduction (RRR) of BCG vaccination was 65.1% (95%CI:57.5;71.4) for pulmonary localization and 65% (95%CI:55; 73) for other localizations. We have not established a significant RRR of BCG vaccination on lymph node TB. Protocol 3 (at birth) had the highest effectiveness with a RRR of 96.7% (95%CI: 86.6%; 99.2%) and 86% (95%CI:71%;91%) in patients with PTB and other localizations TB respectively. In Cox regression model the HR was 0.061 (95% CI 0.015-0.247) for PTB and 0.395 (95% CI 0.185-0.844) for other localizations TB in patients receiving protocol 3 compared to NVC. For lymph-node TB, HR was 1.390 (95% CI 1.043-1.851) for protocol 1 and 1.849 (95% CI 1.232-2.774) for protocol 2 compared to NVC. Depending on the three protocols, the BCG vaccine had a positive impact on PTB and other TB localizations that must be kept and improved. However, protocols 1 and 2 had a reverse effect on lymph node TB

    Abstract Introduction Increasing access to healthcare for expectant mothers is a national goal. In Monastir, Tunisia, some Peripheral Maternity Units (PMUs) required assessment. Our goals were to describe the delivery activities in MUs (maternity units) and to assess whether some of PMUs need to have their activities replaced. Method We analyzed aggregate data of deliveries in Monastir from 2015 to 2020. The gouvernorate’s seven public MUs were included. Only the morning activity was allotted for obstetricians and gynecologists, in RMUs 1 and 2, whereas they were not available in all PMUs. Data was gathered from the reports of the National Perinatal Program. Both the availability of Comprehensive Essential Obstetric Care (CEOC) and Basic Essential Obstetric Care (BEOC) were calculated. Trends were calculated using Joinpoint software. The Annual Percent Change (APC) was calculated. Results The number of births decreased from 2015 to 2020 (APC= -4.3%: 95%CI : -6; -2.4; p = 0.003). The largest significant decreases in APCs of deliveries were reported in PMU 2 (APC = -12.6% (95%CI : -20; -4.4; p = 0.014), in PMU 3 (APC = -29.3% (95%CI : -36.5; -21.4; p = 0.001), and in PMU 4 (APC = -32.9% (95%CI: -49.1; -11.5); p = 0.016). If PMU 3 and 4 were no longer operating as maternity facilities, BEOC and CEOC standards would still be adequat. For accessibility, both PMU 3 and PMU 2 are accessible from PMU 4 and PMU 1, respectively. Conclusions Pregnant women prefer to give birth in obstetric services with ability to perform emergency caesarean at the expense of PMU. Nowadays, it appears that accessibility is less important than the presence of qualified human resources when a pregnant woman choose a maternity hospital
