Roseola?

Okay, I posted a question yesterday regarding red forehead after a fall.  My seven month old was sick earlier this week with a High Fever.  I figured due to teething as usual.  The fever broke, and went away.  She took a nap and when she woke up she had a red blotch streaching across her forehead.   As the evening went on it went to her neck.   Now it is down her back.  A few red areas on her legs.  Her whole forehead and neck is red.  It looks like it breaks up and you see more light areas as it goes down her face and back.  I did some research and it sounds like roseola.  It mainly is on her face and neck not her trunk so I just needed some feedback from someone to confirm.   Thank you so much!!

I have seen Roseola many times and that does not sound like it.  Roseola is small round red dots that do show after the fever has broken.  Of course by that time there is nothing you can do as the spots are a by product of the fever.
NOW..take him to the emergency room or to your doctor and do not get alarmed at what I am going to say. It could be the echovirus(Echovirus is highly infectious, and its primary target is children. The echovirus is among the leading causes of acute febrile illness in infants and young children, and is the most common cause of aseptic meningitis.[3] Infection of an infant with this virus following birth may cause severe systemic diseases, and is associated with high infant mortality rates. The echovirus can mimic symptoms caused by other common bacterial and viral infections, so echovirus infections are often treated with therapies aimed for other infections. This can lead to the evolution of antibiotic-resistant bacteria.) OR IT COULD BE (Scarlet fever is a disease caused by an erythrogenic exotoxin released by Streptococcus pyogenes. The term Scarlatina may be used interchangeably with Scarlet Fever, though it is commonly used to indicate the less acute form of Scarlet Fever that is often seen since the beginning of the twentieth century.[1]

It is characterized by:

Sore throat
Fever
Bright red tongue with a "strawberry" appearance
Characteristic rash, which:
is fine, red, and rough-textured; it blanches upon pressure
appears 12–48 hours after the fever
generally starts on the chest, armpits, and behind the ears
spares the face (although some circumoral pallor is characteristic)
is worse in the skin folds. These are called Pastia lines (where the rash runs together in the arm pits and groins) appear and can persist after the rash is gone
may spread to cover the uvula.)

thanks for the comment.  It helps, believe it or not.  This morning she woke up and the reddened area on her forehead has turned into tiny red spots.  The ones that are on her belly and back are raised, but the ones on her face are flat.  Wierd rash. Going to take her to ER.  this is worrying me.
