Step-by-step explanation:
Yellow fever is a viral illness transmitted by mosquitoes that is endemic in certain parts of Brazil. The disease is caused by the yellow fever virus, which is transmitted to humans through the bites of infected mosquitoes. Yellow fever can range in severity from a mild illness to a severe, life-threatening illness.
In Brazil, yellow fever is a significant public health problem, particularly in the Amazon region where it is transmitted by the Aedes aegypti mosquito, which is also responsible for the transmission of other diseases such as dengue, chikungunya, and Zika. The risk of yellow fever transmission is highest in areas with dense populations of Aedes aegypti mosquitoes and where there is a lack of access to vaccination and other preventive measures.
In recent years, Brazil has experienced outbreaks of yellow fever, with cases being reported in both urban and rural areas. These outbreaks have been driven in part by a lack of vaccination coverage among the population, as well as by the movement of people into areas where the disease is transmitted. The Brazilian government has implemented a number of measures to control the spread of yellow fever, including vaccination campaigns and efforts to control the population of Aedes aegypti mosquitoes. However, the disease continues to pose a significant public health challenge in the country.
