Objective: To identify the determinants of the acceptability and skepticism of health workers about the anticovid-19 vaccination during the covid-19 pandemic in Senegal. Material and methods: This was a cross-sectional, descriptive study carried out among health personnel in the Sangalkam Health District from May 1 to May 15, 2021. A questionnaire was sent to the various health professional categories in the district. Anonymity and confidentiality were guaranteed. The data collected was entered and processed with Excel version 2013 software. Results: The participation rate was 82.5% (n = 140). Women represented 83.6% (n = 117). The average age of the respondents was 36.8 years. The average number of years of experience was 9.8 years. Nursing aides were more represented (23.6%). The vaccine rate was 87.1% (n = 122). The inactivated BIBP vaccine (Sinopharm) was the most administered (93.4%). The side effects were minor or even moderate and affected 30.3% of the vaccinees. On the other hand, 12.9% (n = 18) of the respondents were not vaccinated. The main determinants of vaccine acceptance were concern for protection (68%) and compliance with instructions from the hierarchy (29.5%). Mistrust of the information received (61.1%), fear of rumors (57.2%) and side effects (28.6%) were the main reasons for vaccine refusal. Conclusion: Awareness and communication are essential to remove barriers to anticovid-19 vaccination and increase acceptability.

Sleep disturbances, particularly insomnia, are common in school settings for adolescents. They affect the physical and mental balance with multiple consequences: various pain, fatigue, errors, reduced academic performance, drowsiness in class, repeated absences etc. We conducted a cross-sectional study using a questionnaire and the Epworth sleepiness scale with students from schools in the department of Thiès. The prevalence of insomnia was 21%, with a female prevalence. The average duration of sleep was 8.72 ± 1.1 hours with a variation according to the holidays, the days with or without class the next day. Risk factors are found, in particular living with a tutor other than the parents, the distance of the school from his place of residence, and the morning lesson schedules. Insomnia is significantly associated with sleep debt and excessive daytime sleepiness.
