COVID-19 was first reported in 2019 in Wuhan, China and has since spread widely in China and around the world. Human-to-human transmission occurs through contact with infected secretions, primarily through contact with large respiratory droplets. People with COVID-19 infection may have few or no symptoms, although some patients are seriously ill and die. The risk of serious illness and death from COVID-19 infection increases with age. No vaccine, antiviral medication or other specific treatment is available. However, the means of prevention and health isolation constitute the basis in the fight against the spread of COVID-19. According to the evolving monitoring of the epidemic in Morocco, we will illustrate the importance of hygiene and containment measures as well as the state of health emergency decreed throughout the national territory in improving the epidemiological situation, which is characterized by the decline in the number of deaths and the increase in cases of guresons.
