For HIV you have to look very much country by country. It's not kind of just one prevention strategy. In some countries condoms might be very important or still be important, but it always has to be complemented by a number of other strategies as well. That can be male circumcision in a number of countries, and we are promoting that. You might know that male circumcision alone reduces the transmission rate by about one-third or more. We talked about prevention in young women. It might be better education. There's not one answer. It depends very much on the situation.
Basically, what we say is there are very clear guidelines for prevention coming from our partners, WHO, UNAIDS, and others. That's what the countries put into their programs. We are not telling them how to do prevention. There are international standards. They need to be applied at the country level, and we follow basically the advice of the technical partners. They advise the countries, and we say we fund anything that is the international standard for prevention.
In most cases it will be a combination of different prevention approaches that will be successful.
