  Background 
Conclusion 
Results  
Despite  remarkable  achievements  in  malaria  control,  residual 
transmission still exists in many endemic communities.  
 
Our  objective  is  to  examine  how  human  outdoor  activities  and 
perceptions  contribute  towards  the  ongoing  residual  malaria  
transmission in southern Tanzania.

Behaviour 
Methods 
Human behaviour as observed from activities performed outdoors with no/little protection, play a crucial role to the existing residual 
transmission since when they are outdoors, it is also the time that the host seeking mosquitoes are active outdoors. that people appreciate 
outdoor biting and the likelihood of outdoor transmission but use of intervention other than bed nets indoors, was rare. Therefore, new 
interventions targeting residual transmission must consider the contribution of human behaviour.

• Outdoor activities included buying and 
selling, socializing, storytelling, cooking, 
eating and fetching water, 
 
• The activities took place at times when 
outdoor biting mosquitoes were also active, 
but with little or no protection 
 
• Most people knew of malaria, had 
experienced outdoor bites and complained 
of malaria persistence, though most 
believed transmission occurs mostly indoors
