Serological diagnosis of cysticercosis allows a detection of the disease on living pigs. It routinely uses Elisa as a screening test and Western blot (Eitb) as a confirmatory test. The aim of this study was to assess the performance of the Elisa / Eitb association in order to improve decision-making for the control of this pathology in Côte d’Ivoire. A group of 246 of samples of pigs serums, divided into 123 negative for Elisa and 123 positive for Elisa were drawn at random and were analyzed by the Western blot test. Thus, a contingency table was used to analyze the characteristics of the screening test (Elisa) through the parameters of sensitivity (Sp), specificity (Sp). These performances of diagnostic of the combination of Elisa / Eitb tests was evaluated according to texts design in serial or mixed-strategy. The data obtained for these two patterns were compared. The overall results showed good sensitivity (Se = 76.2%) with average specificity (Sp = 55.4%). The diagnostic performance evaluation of the combination of Elisa / Eitb tests gave 13% serial positives and 17% in the mixed regimen, a difference of 4%. Also, on a total of 123 sreums negatives analyzed by Eitb, 10 or (8.13%) were found positives, corresponding to a loss linked to the screening of samples by Elisa.
Epidemiological monitoring integrating spatial and temporal dimension, geographical information systems (GIS) appear as a management tool, planning tool, and Support Tool Decision of sanitary policies.
This study aims to map cholera sanitary risk in order to improve its monitoring due to better fight against the disease in Abidjan.
The combination, of multi-sources data (QUICKBIRD satellite image, socio-environmental survey results and epidemiological data) in a GIS was used to analyze the sanitary environment in precarious settlements and the spatial pattern of confirmed cases of cholera over the period 2011-2012. This analysis was done using environmental and socioeconomic characteristics that influence vulnerability to cholera and to categorize households according their vulnerability indexes.
Analysis of the results shows that all households are vulnerable to cholera with a high index ranging between 2.5 and 3.5 on a scale from 0 to 5. Boribana and Divo have respective indexes 3.07 and 3.05 followed by Mossikro and Zimbabwe each with 2.94 and 2.92. Bromakot
