E-learning experience during Convid-19 pandemic management:Perception of secondary schools teachers' in Morocco.

Around the world, the COVID-19 pandemic quickly led to the closure of educational institutions in the hope of reducing infections and fatalities due to this disease. Distant education is becoming a policy priority, although institutions and teachers are neither experienced nor accustomed to its use. The purpose of this study is to determine secondary school teachers' perceptions and requirements of distance education during confinement. To our knowledge, none of the similar studies conducted in this area has approached this issue in Morocco. To determine teachers' perceptions regarding distance education, we conducted an analytical and descriptive survey among secondary school teachers in May, June, and July 2020.The chi-square test has been used to test the association between all variables. The association was considered significant when the p-value < 0.05. The calculation of the chi² (X²) and the p-value is performed using R software. The grouping of responses show that most teachers have been teaching remotely during confinement using Whatsapp. They confirmed that this is a useful way to ensure pedagogical continuity during the break from classroom teaching, and they also indicated a preference for both face-to-face and hybrid tutoring.Statistical analysis showed a significant correlation between the subjects taught and distance education (X2= 67.4 with p = 0.01), and a low correlation between training follow-up and distance education during the confinement period r = 0.12. This national study, focused in the secondary school teachers, is pertinent and has showen the extent of the problems of continuous teacher training, as well as strategies that are not evaluated and which do not take into account the perceptions of the actors, including the teacher. This data will be valuable and can be used to establish appropriate measures for improving distance learning tools and the quality and competencies of the actors.

Taxonomic and Ecological Interaction of Leishmaniasis Vectors (Diptera: Psychodidae) in Sefrou Province (Middle Atlas Morocco).

An entomological survey was carried out in the locality of Aichoune to conduct a study on sand flies, species composition, and monthly relative abundance. This study is essential for the implementation of integrated vector management control. Insects collection was carried out twice a month from January 2013 to December 2014 by means of adhesive and CDC-type light traps. A total of 5441 sand flies were collected with the predominance of males (a sex ratio = 1.89). The sampled specimens consist of seven species divided into two genera: Phlebotomus (99.55%) and Sergentomyia (0.44%). Phlebotomus sergenti was the dominant species with an average annual proportion of 47.38%, followed by P. perniciosus (37.32%), P. longicuspis (8,56%), P. papatasi (6.23%), and P. ariasi (0.05%). The genus Sergentomyia was less common (0.44%). S.minuta was represented only by 0.36% and S. fallax by 0.07%. The species dynamics showed a unimodal evolution for P. sergenti and P. papatasi. They were active from May to October. P. perniciosus presents a trimodal trend showing the most relevant peak in August. The highest number of specimens was collected in June, when the temperature reaches an annual average value of 25.5°C. The obtained results will help us better understand the leishmaniasis transmission dynamics in the Aichoune locality and will contribute to the design of a surveillance strategy.

Seasonal Dynamics of Sand Flies (Diptera, Pshycodidae), Vectors of Cutaneous Leishmaniasis, in the City of Fez, Northern Morocco.

The infections transmitted by sand flies (Diptera, Psychodidae) pose always a real health problem due to the increasing number of cases detected each year and the annual emergence of new leishmaniasis outbreaks. This study evaluated the temporal evolution of six species of sand flies in five stations inventoried between May 2017 and April 2018, in order to determine for the first time the extent of cutaneous leishmaniasis (CL) transmission in the city of Fez. The monthly impact of Fez sand fly density has been studied using all multivariate statistical analyses, including multiple factor correspondence analysis (MCA), which were performed using XLSTAT and the version of SPSS 20.0 test. Differences between concentrations were considered significant if P < 0.05. To better study the results obtained, different ecological indices have been studied. This study showed that these vectors developed in different sectors of the city of Fez. A total of 816 sand flies were collected from five stations in the city, belonging to three species of the genus Phlebotomus (46.82%) and three species of the genus Sergentomyia (53.18%). The seasonal fluctuation of the average density followed a bimodal evolution for the three stations Dhar Richa, Ain Nokbi, and Boujloud. The stations of Ain Nokbi (0.87 ph/m2) and Dhar Richa (0.467 ph/m2) exposed the sites to a high average density with a maximum peak during August (1.965 ph/m2) and July (1.87 Ph/m2), respectively. S. minuta (44.24%), Ph. sergenti (26.96%), Ph. perniciosus (10.78%), and Ph. papatasi (9.07%) were the most qualified species. The calculated P value is above the 5% significance level, so the relative abundance of these species between study sites shows no significant difference. The period of phlebotomy activity of the genus Phlebotomus in Fez lasts seven months from May to November with a bimodal or trimodal evolution and varies according to the species or the surveyed station. The seasonal fluctuation of sand flies could be conditioned by climatic factors where the period of activity of the species coincides with the hot months (May, June, July, and August). We have observed that the temperature factor favors the prevalence of sand flies, while the difference in the relative abundance of species between the sites is related to the difference in the bioecological conditions of each site.
