An important step to understanding the dynamics of arbovirus transmission, such as dengue fever, zika and chikungunya, is to get to know mosquitoes’ ability to get infected and to transmit the viruses that cause these diseases. This characteristic is technically known as vectorial competence. A study by researchers of the Oswaldo Cruz Institute (IOC/Fiocruz) showed that the Aedes aegypti has low vectorial competence for the zika virus when...
