  1. It would be nice if there was a vaccine for HFMD, especially for little kids who don’t understand how to prevent the spread of germs.

  2. The implications are scary, but it’s good to be informed. I’m grateful for how informative and candid this article is.

  3. How fascinating that HFMD is spread in so many ways and that even those recovered from it can still be carriers of the infection.

  4. I wish more people knew about how easily it spreads – we could reduce cases if everyone was more cautious!

  5. I feel so much more relieved now that I know when to expect symptoms to appear. I was worried it would be very sudden.

  6. I can’t believe that HFMD is often confused with the animal foot and mouth disease! That’s such a neat comparison.
