Participants from all over the world join the Network by registering themselves and indicating their areas of particular interest in international health. They then search the Network themselves or work through designated County Coordinators to partner with like-minded colleagues. There are many ways the service can foster cooperation:

• A pediatrician in Honduras finds a pediatric practice in Texas willing to host her for a week. Six months later she returns the favor in Tegucigalpa.
• A hospital in Kampuchea receives surgical supplies from individual European and American donors contacted through the Network.
• A student in London finds a doctor in Belize to supervise him on a one month rotation in a Belmopan hospital.
• A relief agency finds 35 colleagues from 12 countries willing to work together on a tropical health education project.
• A non-governmental organization finds seven healthcare workers from three different countries for its upcoming medical relief trip to Mali.
• An academic gastroenterologist in Delhi gives clinical advice to a colleague in Malaysia who is having trouble managing a difficult case.
• A Swiss researcher finds colleagues in six tropical countries willing to collaborate on a tuberculosis research project.
• A disaster relief agency receives rapid situation reports and advice from local health personnel contacted through the Network.
