Dr. Emanuel, from the White House Office of Management and Budget, blogged extensively during a recent two-week trip through Africa.  In this installment he discusses the potential for using male circumcision to prevent HIV transmission.

He goes on to address issues of manpower, facilities, cost, and cultural barriers. Learn more and read the complete post at The New Republic.
