Dr. Cillian De Gascun:

There is also the fact that Irish people tend to be very good about going to work when they are sick. We have that complex whereby we feel we cannot call in sick or stay at home. That is really important as well. If people have respiratory symptoms for whatever reason, they need to stay at home in the coming flu seasons because if they are going to work while coughing and sneezing, they are transmitting something.
