Dr. Nicholas Muraguri is head of Kenya’s National AIDS/STI Control Programme. He spoke with John Donnelly about the scope of the country’s male circumcision outreach plan (170,000 Kenyan males were circumcised last year), the lessons learned, and a problem he sees ahead: funding not keeping up with increased demand for treatment, spurred in part by the circumcision outreach program. This is the final post in a series of interviews on male circumcision (MC), which has been proven to protect a man by up to 60 percent from contracting HIV during vaginal sex.
