Banana bunchy top virus (BBTV) is one of the most severe and widespread virus limiting production and distribution of planting material of banana (Musa spp.) crops in the world. In Democratic Republic of congo (DRc), these crops play a major role in daily life of almost 70% of citizen. Many factors influence banana production negatively such as Banana bunchy top disease. Epidemiological survey was conducted in experimental stations and farmers’ fields for two consecutive seasons covering 72 sites in five provinces of south western of RDc. The objective of this study was to evaluate the presence and distribution of the Banana bunchy top virus in five provinces of South Western of DRc, with emphasis on the agro-ecological factors. A total of 174 Musa spp. leaves samples were collected and analyzed by PcR. The results revealed the presence of BBTV in all provinces investigated. The frequency of BBTV was 6.3% in Bandundu, 12.1% in Kasa?Oriental, 17.8% Bas congo, 1.1% in Katanga and 7.5% Kinshasa Urban and Peri-urban. Results also revealed that BBTV occurred in experimental station and farmers’ fields, both having all cooking and dessert bananas. The high prevalence of BBTV seemed to be linked to multiple introductions of planting materials in the Bas congo province during 1990 and 2002. However, the province of Katanga had not experienced the introduction of planting material. This factor would explain the lowest prevalence of Banana bunchy top virus in this province. The results indicated that there was a real need to facilitate access to genetically improved and healthy certified planting material in these provinces.

Background: Although systemic hypertension is rarely seen in steady state sickle cell disease (ScD), relative hypertension has been reported to be associated with an increased risk of cardiovascular and renal complications. Objective: To determine the prevalence of BP patterns and assess factors associated with relative hypertension insickle cell anemia (ScA) adult patients. Methods: clinical data and office BP were obtained from 103 consecutive steady-state ScA adult patients (mean age 26 ± 7.9 years, 66% females, 22.3% on hydroxyurea) attending four healthcare centers providing ScD-specific care in Kinshasa. Seated BP was measured using an automated electronic device. Three consecutive blood pressure measurements were taken with 2 minutes interval between readings and the average of the 2 last readings was considered for the analyses. Normal BP, relative hypertension and systemic hypertension were defined as BP 120/70 mmHg, 120 - 139/70 - 89 mmHg and ≥140/90 mmHg, respectively. Results: Normal BP, relative hypertension and systemic hypertension were observed in 56 (54%), 43(42%) and 4 (4%) of ScA patients, respectively. In multivariate analysis, factors associated with relative hypertension were leg ulcer (aOR 2.05;95%cI 1.77 - 5.18;p = 0.016), central obesity (aOR 3.32;95%cI 1.28 - 6.24;p = 0.001), smoking (aOR 5.02;95%cI 1.51 - 9.50;p = 0.017), and microalbumiuria (aOR 3.44;95%cI 1.44 - 5.76;p = 0.035). conclusion: Relative hypertension was a common finding in the present case series and associated with traditional cardiovascular risk factor as well as factors specific to ScD highlighting the need for measures to prevent its progression towards systemic hypertension and associated cardiovascular and renal disease.
