I have had a 101+ fever for 4 days went to the dr they said it was a virus. How long is it ok for an adult to have a high fever.

Well: If you don't treat the fever and its a virus the fever goes up and down on its own. Usually if it is a bacterial infection the fever hoed up and stays up. Viruses can last a week or mor depending on what it is. Right now there are some pretty nasty ones with high fevers going around, most with coughs ...Read more

My son had croup 2 days ago. My daughter today has a high fever, no coughing, but she vomitted once. Could it be the same virus or is it totally different. Will I have both a gastro and parainfluenza going through our home?

My son had croup 2 days ago. My daughter today has a high fever, no coughing, but she vomitted once. Could it be the same virus or is it totally different. Will I have both a gastro and parainfluenza going through our home?

Likely same virus: Most probably it is the same virus infection in both the children. Only one vomit does not suggest another infection. Your daughter may start coughing later on. Coughing, diarrhea and vomiting and fever are the common symptoms in respiratory viral infections. Watch your daughter for her symptoms and talk to your doctor. ...Read more

Rapid strep neg but pedi treating because throat looks very suspicious of strep, but she has no throat pain just high fever. Virus or strep?

Hard to know: The strep test is generally predictive, but false negative is possible. More information would be needed for a physician to provide a second opinion (duration symptoms, presence/absence cough, etc).

Tested negative for strep have a real bad sore throat high fever for 2 days what type of virus is this? And how do I beat it.

Sore throat: It could be any kind of virus causing the symptoms described by you. It usually takes more than 2 days to disappear. I would wait at least another couple of days to see if you need further work up. Until then, push fluids, salt water gargles. Acetaminophen or Ibuprofen for pain and fever and rest if you need. Soft foods, avoid hot/cold liquids or anything hard to swallow. ...Read more

Daughter has high fever & stomach pain, probably a virus. When fever is down from tylenol/advil, she keeps shaking uncontrollably. What can be reason?

Virus in the blood.: Once a virus gets into cells, it begins to hyjack it to become a virus-making factory. Once there is enough virus, the infected cell will either shed the virus or else, burst open, leaving millions of virus particles in the blood stream. This sults in the sensation of feeling cold and triggering rigors. When immunity kicks in, they are responsible for the fever and sweats seen with viral inf. ...Read more

Fevers: Fevers for the most part aren't dangerous and are just the body's natural reaction to fighting off an infection. Most of these infections are viral and may be accompanied by runny nose, sore throat, congestion, mild rash, or nothing at all. Since fevers aren't dangerous, we usually treat the fever with Acetaminophen or Ibuprofen just to make the child more comfortable as their body fights the illness.

"red flags" that we look for with fever to indicate something more serious is going on are:
-fevers that last 5 days or more
-fevers persistently above 104f orally
-a child that acts very sick - very irritable or difficult to wake
-difficulty breathing
-vomiting, diarrhea, refusal to drink, or dehydration
-a purple rash, esp on the legs
-stiff neck
-any complaints of pain such as the ear, throat, stomach or a joint

since she is crying as if something is hurting her, you should call her doctor and have her seen. As always, use your judgement. If you think that your child is ill, err on the side of caution and call your child's doctor. ...Read more
