Quite true but equally accurate for all winter viruses that go reach each year. This one seems particularly contagious so extra steps are being taken but each of us could be a flu carrier right now and be unaware.Doesn't matter if you are fit and healthy, if you pick up the virus and become a carrier it's who you pass it it on to.
Hypothetically, if I unknowingly became a carrier due to travel through work, the mother in law is nearly 90 and has just recently had a really bad chest infection, my dad is 83 with underlying health issues and my daughter suffers from asthma, if, I then passed it on to them, they would be more at risk than myself.
