Three pieces in today's Lancet, vol. 371, no. 9622 - a seminar article on the general subject, and a report of a possible case in China, among them.
Several things on malaria, too, which, given the Lancet's good coverage of global health, and the fact that it is World Malaria Day, is not surprising. And an article on global health websites for students.
University of Leicester members can access the Lancet through www.sciencedirect.com - then search for Lancet, vol. 371, no. 9622.
