    Persistent low-grade fever toddler
    ignyc415 posted:
    Our 18month old girl has had a low grade fever (99.5-100.7) for 3 weeks now. This started as what seemed like an ordinary cold. Some sneezing, loss of voice, turned to a cough - lasted about 8 or 10 days then the cold symptoms seemed to subside but the fever persists. We think she caught it from a family friend who was sick with cold. She runs the low fever in the AM after breakfast sometimes, and always around 5 pm for a couple of hours. When she wakes up in the AM she is always normal (98.6 or lower) and same when she wakes up from her afternoon nap. We give her motrin sometimes in the afternoon when her fever rises and her fever comes down before bedtime. She is experiencing no other symptoms except brief periods of lethargy (maybe 30 minutes in the afternoon). She is eating well, happy and playful. She sleeps well too. The only other point of note which might be unrelated is that for about 8 weeks prior to this event, she was always very stuffy in the morning and overnight. She would practically be snoring. We chalked it up to the cold weather starting and the heat drying her out. Since she had this cold and it cleared, she has no more stuffiness in the AM or overnight. Perhaps unrelated. We had the doctor draw blood for the infectious and autoimmune stuff. They said chest x-ray would be next. We will get results in a couple of days. Is there any insight as to what this could be? Is it possible this is nothing serious and it will just go away?

    My 4 yr old girl has been sick on and off for the last few months. Every time it was said to be allergies or sinus infection related. Possibly a cold. Since she is in Pre-K they figured she got something from school. There were times she seemed Lethargic & didn't want to eat, and there were times she was always hungry. In December she started running fever and developed a small cough. I figured it had to do with the congestion she had during the night. The Doctor checked for strep and Pneumonia and that came back negative. She got antibiotics and what ever she had seemed to clear up. Just last week she started to get congested at night again, but fine during the day. We live in Texas, so I just thought it was because of the constant change in weather. I noticed she was developing a small cough, but only in the morning. A few days later she vomited a lot of mucus up. She ran a low grade fever that night. We took her to the Doctor and they tested her for RSV. It came back positive. At the time I had no idea what RSV was. The Doctor put her on breathing treatments. I was told to push fluids & give Tylenol or Motrin. That evening she started to run a high fever of 105.6 and was having trouble breathing. I rushed her to the Emergency room. She was stabilized and then transferred to a Children?s hospital. This caught me off guard, I didn't know how this could be happening so fast and what I could have done to prevent it!

    She is home and feeling somewhat better now. She is still on breathing treatments and steroids. She has ran a constant low grade fever for the past 4 days. I wish I had know of RSV and I might have asked along time ago for her to be tested for it. I am not saying your child has it, but it is worth asking. Your story sounds so much like what we went through.

    Good luck and I hope your little one gets to feeling better. God Bless!

    hi my daughter is 8 years old
    She has been suffering from low grade fever for nearly 60 days now.
    All the reports are normal and we can't seem to pin point the problem.
    I would love to hear what happened in your case.
    We recently got her thyroid tested which seems hi but have to run more tests.
    She runs low grade fever in the evenings and is eating well and hearty
    though she gets tired.
    Do revert

    "Low grade fever" in an otherwise healthy child should be considered normal.

    98.6 is an average-- some people will be higher, some lower. And normal body temperature varies throughout the day, with the highest measured temps in the late afternoon and evening. Many of us, if we measure our temperatures every day, will have a temperature over 100.4 in the late afternoon. That's normal.

    Gaurav, you do need to tie up the loose end of that "seems hi" thyroid test. I suspect that's probably normal, too-- many labs have incorrect reference ranges for children on thyroid tests. Then, as long as your child is fine and thriving and happy and playing, please STOP taking her temperature.

    Sir, I was going through your response. My daughter is 6 and half years old. She had elevated temperature level ( no temp at night i.e 98. but increased up to 100 during the day and gradually decrease) started with the symptom of running nose, caugh and enlarged tonsil. After antibioatic/cold realed medicine by pediatrician the cold symptoms had gone and temperature gradually came back to the normal level 99.6/8 (!!) during day after 14/15 days.We stopped taking temperature at that time. Just after 07 days, she again got running nose. We gave her anti allergic medicine which didn't help. After 10-12 days, she got fever again with sore throat. We went to doctor and doctor gave her antibiotics and nasal spray to treat rhinities as he said. He found pink colour hyper tonsil but didn't diagnose as toncilities.The runnig nose disappeared after 05 days but for last 9/10 days temperature didn't come down - it is normal in the morning/night 98/98.5 and rises to 100/99.5 during the day.Yesterday we consulted with an ENT specialist who diagnosed it as toncilitis and gave antibiotics. I am not much convinced as his opinion differs from Pediatrician who said there is no sign of tonsil infection at present. I am bit confused looking at the temperature trend. Does an infection prompt above mentioned temperature trend? I am much worried if there is no proper diagnosis at present, what will happen in future? What and how would be the proper diagnosis can be done? She has been having repeated runniing nose (with enlarged tonsil as doctor said) for six months and long time raised temperature ( 98 -100) for twice -till yet. We are confused and are very much worried. Please kindly advise.

    My child is 2 years old and is running on his third week of fever. His tmax is 101.3. Initially he came home from daycare with a temp of 104. That lasted two days and this low grade fever persisted. Him and another child in the daycare were diagnosed with hand foot mouth. After the second week, a battery of blood tests came back normal except for a cbc with lymphocytic predominance. His ESR, CRP, EBV and CMV, blood, throat and rectal cx, monospot, ANA all came back normal. He is eating and drinking better and now doesnt seem cranky at all. The only problem is daycare. How long do we just sit on this Roy? Any other thoughts? I think we are dealing with infectious (viral) and rheumatologic, malignancy is off the table.

    100 isnt a fever
    Roy Benaroch, MD replied to An_237681's response:
    What is his "low grade fever" and how have you been measuring it? Does he have any symptoms at all?
    An_245403 replied to Roy Benaroch, MD's response:
    My son is 5 yrs old and had a bout of typhoid after a holiday about 3 weeks back. Ever since that happened, I have cut out any food from outside and have been giving him non-oily, non-spicy food with protiens and veggies and rice (our staple diet). He had lost about 2.5 kgs during the typhoid and he is slowly regaining it. about 3 days back, he caught a cold and fever, the cold was there for about a day and after that he threw up a few times y'day with abdominal pain. He has been having 99.9 deg temp. The doctor gave him a colic pain reliever to which he responded and has not complained of any abdominal pain since then. He has started playing and is active but his temp troubles me. Is it just a viral fever? or could it be something else?

    I noticed these posts were old however I have a question regarding my 14 month old. Today marks day 5 of her on again off again low grade fever (99.2 - 100.2) w/ no symptoms other than her being cranky, clingy, tired etc (as children usually do when they dont feel good). It tends to come on at any given time and we treat with tylenol and ibprofen as per her dr. On day 3 the fever reached its highest of 101.5 as of yet while at her dr appt. He looked her over and couldnt find anything wrong and said it could be just a virus. Note, 2 wks prior she had a cold that he treated with antibotics and cleared up and she also was biten by a mesquito. Her dr doesnt think the bite has anything to do with it nor do I. Could it be that her only the cold symptoms went away (ie. runny nose, cough, thick mucus) but not the cold entirely?

    Hi MsPerez2408,

    Since you posted this 10 months ago, I'm guessing that your daughter's symptoms have improved by now. However, if not, then you might want to have your daughter tested for Lyme disease (it's just a simple blood test; the most sensitive tests are done by Igenex Labs and Fry Labs; you would need to specifically ask your doctor to order tests from these labs, as most doctors defer to the standard LabCorps or Quest labs). Although some doctors believe that Lyme is transmitted only via the deer tick, there are several studies which prove that mosquitos also carry the disease. My 16-month-old son was recently diagnosed with Lyme disease (positive blood test, plus a number of classic symptoms). He had a persistent low-grade fever (99.6 - 100.5) for 8 months; he was also very cranky and tired EVERY DAY. I'm certainly no doctor, but I would like to toss the idea out there just because your daughter's symptoms are similar to my son's. I know there are hundreds of illnesses/conditions that can cause fever/irritability/lethargy, and Lyme is only one of them. But if your daughter still suffers from intermittent bouts of a low-grade fever (plus irritability, lethargy, and developmental delays) with no sign of any other virus/infection, then you might consider a simple blood test to check for Lyme disease.

    Do you have ticks in your area? A persisting low-grade fever is one of the symptoms of the Lyme disease. I really hope this is not the case with your daughter.

    Having low stamina is another thing that can be caused by lyme.
