ZeroFly® Shelter - Field Evaluation

Sierra Leone Camp-Scale Trial

• 2 locations
• Multi-year
• Vector control
• Malaria parasitaemia reduction
• Health impact

A study conducted in Sierra Leone where two large communities of displaced persons were provided with ZeroFly® Shelter demonstrated the performance value and high user acceptance of this technology for malaria vector control. The use of ZeroFly® in such complex emergency settings will allow for rapid coverage of the at-risk population while reducing logistics involved with camp spray programs.

During the dry season the number of mosquitoes obtaining a blood meal was considerably less in sections of the camp where displaced persons lived under ZeroFly® Shelter versus untreated plastic sheeting.

The positive effect of ZeroFly® Shelter in reducing mosquito density, host locating numbers, and successful blood feeding continued even during the wet season 10-14 months after the shelters were installed in the refugee camp.
