Transmission of Major Arboviruses in Brazil: The Role of Aedes aegypti and Aedes albopictus Vectors
Arthropod‐borne viruses (arboviruses) are transmitted to a mammalian host by an infected arthropod vector. More than 130 types of arboviruses are known to cause disease in susceptible vertebrate hosts and are responsible for some of the most explosive epidemics of emerging infectious diseases in recent decades. The transmission cycle requires three essential components: virus, vector and vertebrate. Understanding the role of the vector in the arboviruses transmission is critical to improve emerging arbovirus disease control strategies. Since 2015, Brazil is faced with the challenge of three co-circulating arboviruses of major public health importance. Dengue virus (DENV) infection has been a public health for 30 years, which has suffered several epidemics caused by all four serotypes. The emergence of Chikungunya virus (CHIKV) and Zika virus (ZIKV) in Brazil poses new challenges to clinicians and public health authorities. In urban and suburban areas, those arboviruses are transmitted between people by Aedes mosquitoes in the subgenus Stegomyia, especially Ae. aegypti (the main vector) and potentially Ae. albopictus. Factors relating to the environment and the vector‐virus interactions can influence the dynamics of arboviruses transmission. This chapter describes the main biology aspects of the Ae. aegypti and Ae. albopictus that can influence the success of the transmission of main arboviruses in Brazil and provide information to understand the role of those factors in this dynamic relations
