 During the home visits that CHWs carry during health rounds, selected CHWs will visit every household they are in charge of and will contact women aged 30 to offer them HPV self-collection according to programmatic guidelines. Those women who accept self-collection will be invited to participate in the study, providing them the necessary information about the goals and activities involved. Eligible women willing to participate in the study will be invited to sign an informed consent. The CHW will update the F883 template, the standard primary health care form used by CHWs to collect socio-demographic and health data of the household and its members. CHWs will use a specific questionnaire to collect basic data about inclusionexclusion criteria.
