S.H.
Eeewwww.
This thing was going around before my kids' ended school.
In kids and adults alike.
Scary for me... because I have Asthma.
As they say, a typical cold lasts 7-10 days.
But if you are not getting better, go to the Doctor.
I had that. It was lingering so then I went to the Doc, and at that point I had Bronchitis. Then I needed antibiotics. Then it all went away!
I had the Z-pack.
Take care....
