Malaria is a worldwide disease that causes a high number of deaths. It is caused by the bite of the Anopholes mosquito infected by the parasitic protozoan of the genus Plasmodium. The purpose of this article is to show the numbers of confirmed cases of malaria in Brazil, regarding the years of confirmation, the age group and the notification region, between the years 2011 to 2015. Data taken from the SUS IT department, DATASUS and from articles. There was a decline in the number of the period cited, people between the age group of 20 to 39 years, followed by the group between 49 and 59 years, the largest number of cases occurred with male people, the largest number of cases occurred with people of white race followed by browns, the highest number of cases per schooling is unknown where schooling is known, the highest numbers are with people from complete high school, followed by people with complete higher education, most cases occurred in an urban area , the southeastern region has the highest number of confirmed cases of malaria in the period, the highest number of cases occurred in the state of Rondônia. It is concluded that campaigns had an influence on society and collaborated with the reduction of the number of communicable diseases like malaria. Men work in areas with a higher risk of contamination and in places of vector proliferation, so they are more exposed to areas of mosquito proliferation and contagion. In Brazil the majority of the population is recognized as being white and brown, respectively, so the numbers show these ethnicities as the most infected. The mosquito seems to proliferate more easily in places where there have been man-made changes. The urban environment, as it is an extremely modified place, causes a greater number of cases due to the greater availability of breeding sites. It is believed that for this reason the southeastern region has a greater number of cases and because it is also one of the regions of the country that has suffered the most changes by man. The opening of highways and the increase in settlements facilitate contact between mosquitoes and humans. The state of Rondônia has a large number of settlements and deforestation to accommodate progress.
