Prospective cohort study observes long-term arthralgia in individuals with Mayaro virus infection, indicating clinical patterns similar to other arthritogenic alphaviruses.
During 2010-2013, we recruited 16 persons with confirmed Mayaro virus infection in the Peruvian Amazon to prospectively follow clinical symptoms and serologic response over a 12-month period. Mayaro virus infection caused long-term arthralgia in more than half, similar to reports of other arthritogenic alphaviruses.
