Clonal Spread of Mycoplasma pneumoniae in Primary School, Bordeaux, France

data may be confusing because of potential cross-reactions with other fl avivirus antibodies (in particular in Chad with West Nile virus). Because of probable underreporting from the fi eld, our reported number of confi rmed dengue cases likely underestimates the actual number of cases among French troops stationed in Africa. Nonetheless, our data complement those reported by Amarasinghe et al. by demonstrating additional locations for circulation of serotype 1 (Cameroon, Djibouti, Gabon, Mayotte) and serotype 3 (Comoros). Military epidemiologic surveillance systems can detect dengue circulation where soldiers stay. Thus, these systems could serve to evaluate the risk for dengue infection in countries without local epidemiologic surveillance systems, thereby improving knowledge about dengue circulation in African countries.
