Ethics approval and consent to participate

: The study was approved by the Ethics Review Committee of Assiut Faculty of Medicine (reference # IRB00008718). Verbal informed consent was obtained from both caregivers and children before participating in the study (verbal consenting process was accepted by the ethical review board of the Faculty of Medicine, Assiut University, due to the high prevalence of low education levels, especially in rural areas, the prevailing culture of fear of signing any document, and the nature of research that is not interventional, only questionnaire-based). For illiterate persons, we used the awareness methods where adequate information was given to potential participants, available family members, and health care team in the study sites. Consent from legally authorized representatives (service provision; doctor or nurse or other literate family member) of participants was taken in case of illiterate participants.
