Abstract

Abstract:: Viruses cause various diseases in humans through vector-borne (e.g., Zika and dengue fever), airborne (e.g., measles) and water-borne (e.g., hepatitis) transmission, as well as direct physical contact (e.g., AIDS and herpes). Recently, the new coronavirus (SARS-CoV-2) pandemic has triggered the greatest global health crisis in a century. However, not all viruses in nature are human enemies. A vast body of literature indicates that viral infection is vital for ecosystem functioning by affecting nutrient cycling, controlling species growth and enhancing biodiversity. Here we provide a perspective on the ecological role of viruses in nature, with special focus on Brazilian aquatic ecosystems.

Keywords

Resumo

Resumo:: Os vírus causam doenças em humanos por meio de vetores (e.g., Zika e dengue), pelo ar (e.g., sarampo), pela água (e.g., hepatite) e por contato físico direto (e.g., AIDS e herpes). Recentemente, a pandemia do novo coronavírus (SARS-CoV-2) ocasionou a maior crise sanitária do século. No entanto, nem todos os vírus na natureza são inimigos humanos. Diversos estudos têm mostrado que a infecção viral é fundamental para o funcionamento de ecossistemas, afetando o ciclo de nutrientes, controlando o crescimento de algumas espécies e aumentando a biodiversidade. Esta mini-revisão apresenta uma perspectiva do papel ecológico dos vírus na natureza, com foco em ambientes aquáticos Brasileiros.
