The predictive value of a maculopapular rash in children hospitalized for dengue fever in Cayenne, French Guiana.

In order to determine the predictive value of a rash during dengue fever, a cohort study was conducted in children hospitalized for dengue during an epidemic in French Guiana. A rash was predictive of uncomplicated dengue: the HR of developing a severe form of disease was 0.43 (95% CI 0.21-0.88; p-value=0.021) for patients with rash.
