Dengue Surveillance in Mayotte. Update as of May 25, 2020.

Key Points

  • 4,342 biologically confirmed cases of dengue since the start of the epidemic, including 4,156 cases in 2020.

  • The entire region is affected by viral circulation.

  • The decline in confirmed cases that began in S11 continues, and the positivity rate of PCR tests conducted by the CHM has been falling for six consecutive weeks.

  • Indicators from syndromic surveillance are decreasing but remain high.

  • Only the DENV-1 serotype is circulating, but the importation of other serotypes from the Indian Ocean region remains a real risk.
