Enhanced Disease Surveillance to Understand the Epidemiology of Malaria in Zambezi Region, Namibia

  • Objectives: To understand the local epidemiology of malaria in Zambezi region, Namibia through a series of studies to identify high-risk populations and pilot target active surveillance strategies
  • Abstract: Malaria hotspots (transmission foci) and hotpops (high-risk populations) were identified and described in this border area using a case-control approach. Active surveillance approaches, including peer referral and time-location sampling, were piloted to access and screen potentially high-risk groups.
  • Dates: January 2015 to June 2016

  • Dates: January 2014 to December 2018

Population Movement and Asymptomatic Malaria in the Peruvian Amazon
