Peri-urban schools of Kinshasa before and during COVID-19: an evaluation of water, handwashing facilities, and girl students’ hand hygiene practices

The COVID-19 pandemic has led communities, including Kinshasa peri-urban schools, to reinforce WASH-related practices as a key component in preventing the spread of COVID-19. This study aimed to determine the institutional and behavioural changes in adolescent girl students’ handwashing practices before and during the COVID-19 pandemic. A cross-sectional study was performed, observing the hand hygiene of adolescent girl students, and assessing WASH facilities at schools, chosen from a sample previously selected in the study area. The results indicate significant increases in the prevalence of water points in schools from 10.9 to 22.5%, of handwashing facilities from 43 to 60.1% of schools with an average number of handwashing facilities from one to two, and the prevalence of school WASH brigades from 4.8 to 11.8% of schools. There was also a significant increase in schools receiving funds, and other support for WASH, respectively, from 24.9 to 70.3%, and from 17 to 45.9%, while the proportion of adolescent girl students washing their hands after using the toilet and before eating significantly increased from 6 to 28.4%. However, to improve the current WASH picture, and succeed in curtailing the spread of COVID-19 and related impacts, additional efforts to enhance handwashing practice and WASH items’ coverage are expected.
