A Brief Analysis on the use of Artificial Neural Networks for COVID-19 Pandemic in Portugal

The evolution of the number of new cases of COVID-19 and its number of related deaths is causing panic in the world population. Portugal is a small country in terms of people, but this country has had many deaths since 2020 associated with COVID-19. Based on the recent studies available in Google Scholar, this paper will explore the different techniques used to predict this pandemic situation to control its evolution. This study found that the COVID-19 is the subject of several research studies. The main objective consists of collecting the used artificial intelligence techniques for further improvements of the system created in previous research to help the educational institutions detect early COVID-19. These studies are helping to develop technologies for the prevention of this virus. The use of sensors, Big Data, and Artificial Neural Networks will accelerate the early detection and treatment of COVID-19. However, it is difficult to predict the treatment's evolution dispersion of the cases with the appearance of new variants. Still, the Portuguese dataset is publicly available and can be researched in the future.
