Leptospirosis

  • Federated State of Micronesia (FSM): The Bacterial Special Pathogens Branch at the Centers for Disease Control and Prevention conducted further testing and investigation on screened positive leptospirosis cases seen in Yap and did not find evidence suggestive of an outbreak of acute leptospirosis infections during the dengue outbreak. The numbers probably represent the background activity of leptospirosis. Rapid Diagnostic Test (RDT) seemed to be primarily detecting patients having prior exposure to leptospirosis.
