Hopefully, we are all vaccinated against Covid and flu but we haven't been exposed to cold viruses for a year.
My daughter's 2 year old has already got a snotty nose presumably picked up from her nursery which she is in the process of spreading to the rest of the family.
I can't decide whether I've picked up a cold or crossed paths with an allergen, but currently I have got the sniffles after a couple of sneezing bouts yesterday. As I've been nowhere other than at work (3 days last week, didn't go out over the weekend not even to the shops, and 2 days this week), it can be the only source which is worrying (given that Covid cases are definitely on the rise in this area). The allergen is a strong possibility as the sneezing attack came on so suddenly without warning at work but the still drippy nose today (I decided to stay and work from home to be on the safe side) isn't characteristic of an allergy.
