Estimating Chikungunya prevalence in La Réunion Island outbreak by serosurveys: Two methods for two critical times of the epidemic-1

On-based SEROCHIK survey (right scale). For the serosurvey, both self-reports (all subjects who have declared that they have been infected, without taking into account serology results) and confirmed self-reports (with a positive serology) are noted. We refer to the date of first clinical signs declared by the subjects during the survey conducted between August 172006 and October 202006. "Suspected cases" are defined as cases with a sudden onset of fever with temperature > 38.5°C and incapacitating arthralgia.<p><b>Copyright information:</b></p><p>Taken from "Estimating Chikungunya prevalence in La Réunion Island outbreak by serosurveys: Two methods for two critical times of the epidemic"</p><p>http://www.biomedcentral.com/1471-2334/8/99</p><p>BMC Infectious Diseases 2008;8():99-99.</p><p>Published online 28 Jul 2008</p><p>PMCID:PMC2528011.</p><p></p
