In the battle against diseases like Zika and dengue, knowledge is power. Climate change is shifting the distribution of mosquitoes and to new areas. Empowering communities is essential in reaching and pro- tecting the most vulnerable individuals and households. Vector control programmes, community empow- erment and awareness campaigns are proven strategies to reduce the burden of vector-borne diseases. Red Cross and Red Crescent volunteers can play a key role in community and school outreach activities for Zika, dengue and chikungunya prevention. These community-based activities need to be sustained to ensure long-lasting disease control.
