Haven't seen that in my part of the world yet but it doesn't mean something's not going around.
I'd clean her up and put her to bed and check in on her a couple of times overnight. Best to let her rest and get some sleep if she can sleep. Make sure breathing sounds good and look at her color, make sure lips are nice and pink (not blue) and she's not breathing fast or labored. If yes, that's an ambulance call.
Tomorrow when you get her up, check her temp, if it's high (like over 101) then give her some tylenol or motrin to try to get her comfortable so she can eat/drink. Keep watching the breathing, if you are unable to keep fluids down I'd definitely call for a Dr. appointment. She doesn't need to drink a lot, especially with an upset tummy but she needs a little bit ever so often. Pedialyte pops are good and they go down slow so as not to upset the tummy more.
You need to see at least 1-2 good pee diapers every 8 hours. Make sure eyes are nice and wet and not sunken in. If she starts to look dry or isn't peeing, that needs a Dr visit during normal hours or an urgent care visit during the night/weekend hours.
Fever is good, it's cooking the germs. But if it goes over 101 and you can't budge it with Tylenol or Motrin so she can eat/drink, you need to try to see the Dr. as well.
I usually try to manage this stuff at home because I don't want to pick up some other crud beyond what my kid already has...BUT I have a 3 day limit. If at day 3 she's not better (like if she's still running a fever) then I take her just to make sure we are on the right track.
Hope this helps, good luck and hope she gets well soon!
