The Middle-East Respiratory Syndrome (MERS-CoV) was originated in 2012, and is caused by a bat´s coronavirus that broke the species barrier until it could affect humans and generated an epidemic that is affecting several Arab and European countries. Objective. Study, retrospectively, MERS-CoV from cases registered in humans, by the use of the information available and provided by the World Health Organization and the International Society for Infectious Diseases, ISID. Materials and methods. An observational retrospective study of the descriptive type was performed, analyzing the information from the daily cases and having as a reference the frequency and the distribution of an epidemiological event that corresponded to the morbidity and the mortality, in order to describe occurrence patterns related to the individual variables (gender, age, race, etc), the time and the place. Results. The highest percentage of cases reported took place in May 2013, affecting older adults. There were cases in countries such as Saudi Arabia, Jordan, Germany, Italy, France, England, Morocco and the Middle East. Conclusions. The current importance of emerging viruses and their relation with the epidemiology and the public health has been reaffirmed, and so has the necessity of making follow up studies in order to determine possible reservoirs, secondary guests and future prevention measurements.esCorporación Universitaria LasallistaSíndrome respiratorio del medio orienteCoronavirusZoonosisEpidemiologíaArticle
