The prediction of solar potential is an important step toward the evaluation of PV plant production for the best energy planning. In this study, the discrete Kalman filter model was implemented for short-term solar resource forecasting one the Dakar site in Senegal. The model input parameters are constituted at a time t of the air temperature, the relative humidity and the global solar radiation. The expected output at time t+T is the global solar radiation. The model performance is evaluated with the square root of the normalized mean squared error (NRMSE), the absolute mean of the normalized error (NMAE), the average bias error (NMBE). The model Validation is carried out by means of the data measured within the Polytechnic Higher School of Dakar for one year. The simulation results following the 20 minute horizon show a good correlation between the prediction and the measurement with an NRMSE of 4.8%, an NMAE of 0.27% and an NMBE of 0.04%. This model could contribute to help photovoltaic based energy providers to better plan the production of solar photovoltaic plants in Sahelian environments.

Abstract Background Niger is a large country with many distant locations that can be difficult to access because the Sahara Desert covers 80% of the country’s land. In Niger, just 49% of residents have access to a health centre within 5 km of their house. Health care may be difficult to access in the Diffa region of Niger, as non-state armed groups strike on a regular basis and floods cause a high rate of vulnerability. This study looked at how mobile clinics can improve healthcare accessibility for vulnerable populations in the Diffa region. Methods This was a descriptive-comparative study conducted over the period from 15 August 2022 to 15 October 2022, using three months’ mobile outreach clinic to improve health outcomes in five districts of the Diffa region, including Bosso, Diffa, Goudoumaria, Mainé Soroa, and N’guigmi. Results During the three months of mobile outreach clinic, 42,251 people were sensitized about mobile outreaches and 12,004 were treated. A total of 18,708 vaccine doses were delivered to children aged 0–11 months, with Maine Soroa, Goudoumaria, Bosso, Diffa, and N’guigmi districts accounting for 29.24%, 24.62%, 18.54%, 18.05%, and 9.5%, respectively. In the same line, Goudoumaria, Bosso, and Maine Soroa districts recorded relatively high antenatal clinic (ANC) attendance percentages of 27.85%, 25.62%, and 21.89%, respectively. Furthermore, mobile clinic outreach provided a variety of healthcare treatments, both curative and preventative. Mobile Clinic 2 increased vaccine dose received among children aged 0–11 months by 1.11% (95%CI: 0.15%-2.06%, P = 0.023) when compared to Mobile Clinic 1. In the same line, mobile clinic showed a statistically significant increase of ANC between the three clinical rotations (P = 0001), showing an increased ANC update over time. Conclusion This study found that mobile outreach clinic can play an important role in improving healthcare access for vulnerable populations in the Diffa region. However, well-designed, and frequent mobile clinic outreach should be planned and included in the country’s public health policy.

Abstract Background Effective case management of malaria requires prompt diagnosis and treatment within 24 hours. Home-based management of malaria (HMM) improves access to treatment for populations with limited access to health facilities. In Senegal, an HMM pilot study in 2008 demonstrated the feasibility of integrated use of RDTs and ACT in remote villages by volunteer Home Care Providers (HCP). Scale-up of the strategy began in 2009, reaching 408 villages in 2009 and 861 villages in 2010. This paper reports the results of the scale-up in the targeted communities and the impact of the strategy on malaria in the formal health sector. Methods Data reported by the HCPs were used to assess their performance in 2009 and 2010, while routine malaria morbidity and mortality data were used to assess the impact of the HMM programme. Two high transmission regions where HMM was not implemented until 2010 were used as a comparison. Results and discussion From July 2009 through May 2010, 12582 suspected cases were managed by HCPs, 93% (11672) of whom were tested with an RDT. Among those tested, 37% (4270) had a positive RDT, 97% (4126) of whom were reported treated and cured. Home care providers referred 6871 patients to health posts for management: 6486 with a negative RDT, 119 infants Conclusion Home-based management of malaria including diagnosis with RDT and treatment based on test results is a promising strategy to improve the access of remote populations to prompt and effective management of uncomplicated malaria and to decrease mortality due to malaria. When scaled-up to serve remote village communities in the regions of Senegal with the highest malaria prevalence, home care providers demonstrated excellent adherence to guidelines, potentially contributing to a decrease in hospital deaths attributed to malaria.

Observation of an Outbreak of Equine Trypanosomiasis due to Trypanosoma vivax in Urban Environment in Senegal. An outbreak of trypanosomiasis in imported and local horses and ponies occurred in September 1994 in a private horseriding farm near Dakar. Trypanosoma vivax was isolated. 5 mortalities (which a local pony were registered on 20 ill animals. The clinical signs were fever, depression, emaciation, anemia ad oedema. Curative treatment with intramuscular diminazene (3.5 mg/kg) and prophylactic intravenous isometamidium (0.5 mg/kg) were injected in October 1994 and July 1995. Glossina palpalis gambiensis was isolated near the farm.
