Though I don’t speak a word of French (ok, I can say bonjour and oui oui!), based on these signs at the Dakar (Senegal) and Bamako (Mali) airports I'm guessing that there is a new strain of the H1N1 virus (swine flu) that we should be worried about. I’ve been amazed at all of the materials around the airports providing information on the flu. There was an alert about H1N1 on the immigration forms we had to fill in for entry to Morocco as well as Senegal, and while waiting for our flight to Mali, I saw a video on how to prevent people from getting sick/getting others sick (washing hands, wearing masks, etc). Good thing we brought Tamiflu!
