insurance for student exchange

[Eileen C Thurman]

        I am organizing my first ever student exchange with a school in
St. Petersburg, and seek information on good health and travel insurance
for my students and for the Russian students coming to the US. I have a
brochure from a company named Worldwide Assistance, 1133 15th St, NW,
Suite 400, Washington, DC, 20005.
Can anyone tell me of past experience with this company? Any
recommendations from those of you experienced in student exchanges?
