World of Viruses is funded by the National Center for Research Resources at the National Institutes of Health through the Science Education Partnership Award (SEPA) Grant No. R25 RR024267-01 (2007- 2012). Science Education Partnership Awards (SEPA) are designed to incorporate inquiry-based learning experiences to stimulate interest in science, further public understanding of health issues, and encourage the next generation of health professionals. With an emphasis on reducing health disparities, the program's K-12 projects target minorities and students in rural and underserved communities. The awards support enhanced training for science teachers; the development and distribution of hands-on science curricula; and Web sites for students, teachers, and the general public.
