Well I've pulled DCs out of nursery because of the cases there.
Last winter we had two hospital stays and ill children from October to March. GP confirmed it was likely because DC went from 2 years of absolutely no exposure to viruses to suddenly being in a room full of kids daily (kids who also had no immune system so were picking up bugs everywhere and sharing them. Basically overloading their systems all at once.)
So far this winter we've had two heavy colds back to back, with croup a few weeks ago and the cough still hasn't cleared from that.
GPs in my area are in "high alert" according to website and receptionists for this step A. Advisory messages about the effects and those at higher risk etc.
Yes, it's usually a pretty manageable virus but this strain is spreading like wildfire in some locations and even being referred to as serious outbreaks, and our kids quite simply do not have the immune systems we probably would have at their ages. It also takes 2 working days, 3 hours on the phone and a bit of luck to get a GP appointment so in all honestly I will do anything to avoid that.
GPs, hospitals etc are all on their knees already. Everyone should be doing all they can to avoid picking up this virus and others to help support the NHS through this outbreak.
