The rapid spread of the COVID19 virus surprised most of the world's public health specialists and pushed various countries to adopt palliative measures. These measures ranged from total containment, to the elimination of physical contact between people and the use of ICTs to follow up infected cases. Many IT solutions have been developed everywhere else, if they have been able to provide answers in the countries where they have unfortunately been implemented for Cameroon, they do not seem suitable. Faced with this situation, our article proposes a cartographic management system to respond in the future to different types of infectious diseases, it is therefore based on the “divide and conquer” paradigm and the concepts of cartography to guarantee effective management of disease. A system that takes into account the specifics of Cameroon's response to Covid-19. This system is built in an environment integrating the use of mobile techniques, in particular Bluetooth technologies and mobile geographic information systems, in order to allow the monitoring of patients and the traceability of the evolution of the disease; this platform also offers a framework for consultation between patients and medical specialists for the sharing of experience in order to limit the spread of the virus present.

Cameroon is known as Africa in miniature and therefore has great tourism potential. In view of the low level of exploitation of this wealth, the State of Cameroon has committed since 2010 to the redevelopment of sites, access roads and places of recreation. For an effective and efficient dissemination of its tourism offer, a webmapping application was implemented in 2012. However, it could not be published due to a number of shortcomings, in particular the use of a mono scale map at 1: 500,000 and the lack of interactivity with the map. In this article we propose an improved version of this application and through a software development process, a new platform has been implemented and allows on the OSM multi-scale basemap, interactive access to tourism offers on Cameroon in providing descriptive information and illustrative photos on request.
