Public health officials have been bracing for locally transmitted cases.
Other than the spread from mother to fetus in utero and two sexually transmitted cases via contaminated semen, there is no evidence of person-to-person transmission of the Zika virus.
These 5 states transmitted case-based data with a minimal variable set to the Robert Koch-Institute (RKI), the federal institution responsible for disease control and prevention, from 1995 to 2000, enabling a basic demographic analysis.
Autochthonous (locally transmitted) cases of most of these infectious diseases have been reported in Europe.
In the years 2003 to 2007, among teenagers (10 to19 years) females represented the majority of heterosexually transmitted cases (Table 1).
The recent occurrence of 2 locally transmitted cases of chikungunya in France, despite a low number of imported cases (6 ), shows that the risk remains high.
Recently transmitted cases were defined as cases with matching results reported within statistically significant geospatial zones (identified by a spatial span statistic within a sliding 3-year window).
However, it is also true that all TcIDOM strains we isolated originated from patients with chronic infection, and all orally transmitted cases were in the acute phase.
The odds ratios were recalculated after sampling by moving the clustered cases that were sampled as unique from the category of recently transmitted cases to the category of reactivated cases and reassessing the respective exposure status for these outcomes.
