      An excellent hub at the right time to aware people about H1N1. I read from reports that swine flu is back again and the virus now is not so aggressive as they are in 2009. So the virus is keep rotating. If you have flu-like symptoms, stay at home and if the fever continues for more than 2-3 days immedietly give tests for swine flu. Rated up and useful. Shared.

      Interesting hub. I hope it doesn't come around again. I remember several people at my work catching it. It takes a while to recuperate.
