BackgroundWorldwide, governments have implemented restrictions on movement and gatherings to contain the COVID-19 pandemic. In the spirit of the Convention on the Rights of the Child, children have a right to express their opinion on matters of concern to them. The study aimed to describe and analyse how adolescents in the capital Bissau understood the unfolding COVID-19 pandemic and their lived experiences during the first 3 months of the pandemic.MethodsCollaborators identified participants in five urban areas in Bissau in June 2020. Semistructured, open-ended interviews were conducted with 30 adolescents aged 15–17 years, attending private and public schools or out-of-school. The interviews were conducted in Kriol, recorded, transcribed, translated and analysed.ResultsAll the participants were heavily affected by the confinement measures during a state of emergency. Almost all believed in the realness of coronavirus while there were some doubts about its arrival in the country. The consequences were staying at home, enforced with increased police violence. At the same time, other violence on the streets or between neighbours had decreased. A few participants said they liked staying at home because they appreciated spending more time with their families. Most participants claimed that they and their family members tried to follow preventive measures. Almost all participants voiced concerns about the worsening financial situation at home, leading to food scarcity. Nearly all the adolescents were tired of the lockdown and worried about the pandemic’s implications on their future opportunities.ConclusionsStudy participants, here adolescents in Bissau, have a clear notion of their existence and the current situation’s potential negative impact on their future. Their voices need to be heard and acted on, which may soften the lockdown’s negative impact on adolescents in Guinea-Bissau, as elsewhere.
