Overview

Randomized trial examines local WNV amplification in urban environments, indicating the need for sustainable planning.

Key Points

  • The aim is to understand how urban land cover affects West Nile virus amplification in Berlin.
  • Examined mosquito sampling at five sites in a one-square-kilometre area in Berlin.
  • Analyzed seasonal WNV infection rates over two mosquito seasons in 2023 and 2024.
  • Considered habitat characteristics and avian host community structure in relation to infection rates.
  • Seasonal WNV infection rates reached up to 4.8% in mosquitoes, with residential areas showing a maximum of 15% and cemeteries 21%.
  • Natural conservation and sponge city sites exhibited significantly lower infection rates of up to 4% and 13%, respectively.
  • Infection risk did not correlate with mosquito abundance but with habitat characteristics and host community composition.
