| dc.description.abstract | Following the declaration of COVID-19 as a global pandemic and the reporting of one case in
Senegal, the number of regions with confirmed cases of infection increased considerably, with the disease
now being reported throughout the country after 3 months of evolution. It is therefore necessary to assess
the evolution of the disease in the country as the situation evolves in order to rapidly identify best practices
for adoption. The objective of this paper is to make a preliminary spatial and temporal assessment and
comparison of the results of the COVID-19 pandemic in the regions of Senegal. Data on the evolution of
COVID-19 (confirmed cases of infection, deaths, recoveries), population, density and area of each region
were analysed using a set of statistical tools. The results show that the COVID-19 pandemic has spread
stubbornly in Senegal. In the space of 112 days (from March 2 to June 21), Senegal reached a number of
5888 infected cases for 3919 cured, 1885 active and 84 deaths for a total of 67855 tests performed. About
40 people out of 10,000 have been tested so far and 4 out of 10,000 have tested positive. The Mann-Kendall
test indicates that the number of confirmed daily cases is slowly increasing, with the slope of Sen estimated
at about 1.2 person/day across the country. In addition, the Pettitt test indicates a sharp change in the
upward trend across the country on April 26, 2020. Among the main affected regions, Dakar, Thies and
Touba are noted with an extremely high rate of increase. Principal component analysis and hierarchical
ascending classification have made it possible to divide Senegal's 14 regions into 3 groups in terms of the
number of confirmed cases, active cases, recovered cases and reported deaths, and the population, area
and density of the region. The 1st group concerns the Dakar region, the 2nd Diourbel and Thies and the 3rd the
other regions. Furthermore, statistics related to COVID-19 in the regions of Senegal are highly correlated
with population size and density. This study revealed convincing spatial differences in the evolution of the
pandemic between the regions of Senegal. The study recommends that the approaches adopted by regions
that have achieved very low levels of COVID-19 be incorporated into health care management plans for
the pandemic throughout the country, even as the situation evolves.
