Brief summary

The Human Papillomavirus (HPV) is well established as the primary causative agent in both warts and cervical cancer. Although cervical high risk HPV (hrHPV) infections have a high rate of spontaneous resolution this takes time and the infection can cause cervical cells to progress to precancerous and cancerous lesions. Zinc has been shown to play a central role in immunity. This study is to determine if oral zinc sulfate can improve clearance rates of high risk HPV versus placebo.

Detailed description

Upon enrollment eligible participants will be randomized and given a three-month supply of zinc sulfate or placebo to be taken as directed. They will have zinc serum lab testing at enrollment and upon study completion. Patients will also be asked to complete short questionnaires and to make study staff aware of any side effects they should experience.

Interventions

DIETARY_SUPPLEMENTZinc Sulfate

Participant will take one 220mg tablet twice daily for three months.

OTHERPlacebo (Gelatin Tablet)

Participant will take one tablet twice daily for three months.
