Arboviruses related with chronic musculoskeletal symptoms

Arboviruses (ARthropods BOrne VIRUSES) are disease-causing viruses transmitted through the bite of hematophagous arthropods, such as mosquitoes and ticks. Among these, the alphavirus, genus of the Togaviridae family, is considered the most arthritogenic species, responsible for diseases such as chikungunya fever (CHIK), O'nyongnyong virus fever, Ross River virus disease, Barmah Forest virus disease, Sindbis virus disease, and Mayaro fever. These arboviral diseases, especially CHIK, have impacted public health in recent decades, leading to devastating epidemics, particularly in developing countries, due to their high potential for chronicity, functional impairment, and great impact on the quality of life. In a similar way, chronic musculoskeletal symptoms have been described in all alphavirus infections. However, CHIK is the best studied. The purpose of this article is to review physiopathology, clinical manifestations, diagnosis, and treatment of alphaviruses, focusing on CHIK and chronic evolution of musculoskeletal symptoms.
