Caries levels and patterns in head start children in fluoridated and non-fluoridated, urban and non-urban sites in Ohio, USA.

Abstract: The purpose of the study was to determine caries levels and prevalences of previously identified caries patterns in low income children in the primary dentition in Ohio, USA. Children were examined from urban fluoridated (n = 505), urban non-fluoridated (n = 395), non-urban optimal fluoride (n = 183), and non-urban suboptimal fluoride (n = 227) sites. Caries scores were similar for the two sites having optimal fluoride; scores from fluoridated sites were lower than scores from the two suboptimal fluoride sites. Children from all four sites were caries-free ranging from 36% in the urban non-fluoridated site to 50% in the non-urban optimally fluoride site. More children in the suboptimal fluoridated sites had smooth surface lesions than in the optimally fluoridated sites. More children with defect associated lesions had fewer than six (chi 2 = 222; P less than 0.01) carious surfaces than did children with smooth surface lesions.

Aedes canadensis, a vector of La Crosse virus (California serogroup) in Ohio.

Abstract: Aedes canadensis was shown to be a vector of La Crosse (LAC) virus in Ohio through isolation of LAC virus from field-collected specimens, infection of 54 of 72 (75%) individuals when fed on viremic suckling mice and transmission of LAC virus by 29 (54%) of infected individuals. Frequent identification of Ae. canadensis as a human biting species implicates it as an auxiliary vector of LAC virus to man. A possible regional association in Ohio of Ae. canadensis and Type C LAC virus is discussed.
