Chikungunya Epidemic in Brazil
Chikungunya fever has become a significant public health concern in Brazil, characterized by its high prevalence due to favorable climate conditions for Aedes mosquitoes. The country recently reported approximately 400,000 cases within a single year, contrasting with no reported cases in Europe during the same period. Chikungunya presents acutely with severe symptoms including high fever, polyarthritis, and myalgia, resembling rheumatoid arthritis flares. Distinguishing chikungunya from other rheumatic diseases is crucial, as a notable percentage, around 40-50%, of chikungunya patients can develop chronic arthritis, impacting their quality of life.
