In 2020, the Government of Guinea-Bissau, with the support of its partners including UNDP, carried out a national campaign to distribute Long-Lasting Insecticide-treated Nets (LLINs) to the entire population in line with the WHO recommendation of a three-year campaign cycle. Due to the coronavirus pandemic, strategy adaptations were required, following the recommendations of WHO, the Global Fund, and Alliance for Malaria Prevention (AMP) for the COVID-19 context. The distribution of LLINs to each household was, therefore, carried out door-to-door (instead of at fixed outreach distribution points) through 4,414 community health workers and 4,414 mobilizers (and the same number of support staff tasked with transporting the LLINs using local means, such as wheelbarrows). 

At the end of the campaign, 2,293,177 people had access to LLINs for protection from malaria, through the distribution of 1,287,746 LLINs before the high transmission season. This equated to one LLIN for every 1.8 people (provisional administrative data). Strong engagement of all actors involved in the campaign at a time when the state of emergency was declared ensured a rapid strategy review and adaptation to align to the context of COVID-19 and the measures for its prevention put in place by the Government of Guinea-Bissau. 

Three strategies namely, advocacy, social mobilization and social and behaviour change communication made the results possible. Political, administrative, and religious representatives, NGOs and associations, civil society organizations, media leaders, etc. were involved in all three strategies. The strong communication campaign at all levels allowed for greater involvement of the community and household members in the campaign, avoiding adverse rumors about the campaign, and allowing good final coverage of households with LLINs.
