In the context of poliomyelitis eradication, a reinforced sentinel laboratory network for surveillance of enteroviruses (RSE) was implemented in France in January 2000, and the purpose of this report is to describe the results of the five first years of surveillance. From 2000 to 2004, the RSE laboratory network performed detailed surveillance of the circulating enteroviruses. No wild-type poliovirus was isolated from humans during the 5 years of surveillance, although two imported vaccine polioviruses were detected. During the same period, Sabin-like polioviruses were identified on five occasions in the sludge from sewage treatment plants, but no wild-type poliovirus was found. Over the 5 years of surveillance, information was collected from 192,598 clinical samples, including 39,276 cerebrospinal fluid specimens, of which 14.7% were positive for enteroviruses, 45,889 stool samples (4.3% positive for enteroviruses), 70,330 throat swabs (2.2% positive) and 14,243 sera (1.4% positive). The ten main nonpolio enteroviruses typed were as follows, in decreasing order of frequency: E-30, E-13, E-6, CV-B5, E-11, CV-B4, E-9, E-7, CV-B1, and CV-B2. During the year 2000, an outbreak of aseptic meningitis due to three main enteroviruses (echoviruses type 30, 13, and 6) was monitored. Continued surveillance of enteroviruses is important to alert physicians and public health officials to changes in disease trends. Although the geographical coverage of the RSE network as well as the percentage of enteroviruses identified must be improved, the large number of samples tested for enteroviruses shows the ability of virology laboratories to detect the circulation of enteroviruses and to report the possible identification of poliovirus (wild-type, vaccine-derived, or Sabin-like).
