My daughter has high fever ?

In the first instance, ring 111.  They will advise you what to do based on the full details.  We can't advise - not just because we are not doctors, but we also don't have the details. 

First administer some Tylenol then a lukewarm bath or shower to bring down the fever then you call a doctor

You need 111 they might send out a paramedic. You can no longer turn up at A&E you have to phone 111 first.

HUNCH we don't go straight to urgent care because of the high rate of Covid, a Doctor or Paramedic will come to the house FREE, no insurance.

Call your doctor or 111, they should be able to advise you if you have to take your daughter to the hospital or not. If you need emergency treatment call 999.
In the mean time try things like asprin (meant for children if she's a child) to get her fever down. 

I AM PROUD TO BE AN AMERICAN, WHERE AT LEAST I KNOW I'M FREE.
I DO NOT NEED TO CALL 111 TO GET THE TREATMENT THAT I NEED.

I CAN VIDEO CHAT WITH TELEDOC OR CALL MY DOCTOR IF THAT IS BEST
IF MY SYMPTOMS SUGGEST, I CAN DRIVE TO URGENT CARE
OR IF I TAKE A TURN FOR THE WORSE, I KNOW THE ER IS THERE.

THE GOVERNMENT DOES NOT DICTATE THE HEALTHCARE THAT I RECEIVE. 

I AM PROUD TO BE AN AMERICAN, WHERE AT LEAST I KNOW I'M FREE.OUR MEDICAL COMMUNITY IS ABLE TO ADAPT TO GIVE THESE CHOICES TO ME.

One look at the answers on this post and universal healthcare would be off the table in the USA.
