Exploring children's knowledge of COVID-19 and stress levels associated with the pandemic in Nigeria: a mixed-method study.

Nigerian children in this study had good knowledge and understanding of the COVID-19 pandemic and preventive measures to counter the virus. Children had high stress levels and expressed pandemic-related concerns but parental love and support were mitigating factors. Government and child health service providers need to tailor health and support services in response to children's needs and concerns.
