This chapter discusses the renal involvement in arboviruses, focusing on chikungunya, dengue, and Zika, all transmitted by mosquitoes, primarily Aedes aegypti and Aedes albopictus. These arboviruses can range from mild symptoms to severe complications, including renal damage. Chikungunya presents with high fever and severe joint pain, and its renal complications include acute kidney injury (AKI) and glomerulopathies, possibly linked to immune dysregulation. Dengue, the most prevalent, can also lead to AKI, proteinuria, and electrolyte imbalances, such as hyponatremia and hypokalemia. Severe dengue is associated with capillary leakage and renal complications, which may require dialysis. Zika, though primarily known for neurological impacts, also exhibits renal involvement, with viral persistence in renal tissue and evidence of tubular and glomerular damage. This chapter explores the pathophysiology, clinical manifestations, and current scientific understanding of how these viruses affect kidney function, emphasizing the need for early detection and supportive treatment. Although antiviral therapies are not yet available, preventative measures like vaccines and vector control are crucial in managing the spread and impact of these diseases.
