Uma definição de vírus
Os vírus são partículas constituídas por filamentos de ácidos nucléicos (DNA ou RNA), incluídos numa capa protéica
Podem ser produzidos tanto por células vivas, quanto por processos bioquímicos, "ïn vitro"
Quimicamente, é um fragmento de ácido nucléico recoberto por proteínas associadas, ou não, com lipídios de membrana

Vírus transmitidos por insetos Os artrópodes hematófagos compreendem os
insetos (6 patas na fase adulta) e os carrapatos (8 patas na fase adulta) que se alimentam de sangue.
Podem ser vetores de infecções, por serem capazes de transmitir agentes infecciosos entre seres humanos ou entre animais e seres humanos.
Estes artrópodes não servem apenas como meio de transporte mecânico, uma vez que neles ocorre, obrigatoriamente, parte do ciclo de desenvolvimento dos agentes infecciosos.
