Ethics Statement
The Institutional Review Board of the University of Florida exempted the
study from review (Exemption of Protocol #2009-U-0422) and waived the
need for written informed consent of the participants. This exemption is
issued based on the United States Department of Health and Human
Services (HHS) regulation 45 CFR part 46, because louse removal was
voluntary and no identifiable information was recorded and so the need
for written informed consent from the participants was waived.
