Your child most likely has a mild viral fever, which is very common in children and can occur without obvious symptoms like cough, cold, or stomach issues. A temperature around 38–38.5°C for 2–3 days that responds well to paracetamol (Panadol) usually suggests a simple viral infection, and this often settles on its own within a few days.
Because he has autism and difficulty expressing symptoms, signs like dullness, low appetite, or saying “head hurts” may simply reflect feeling unwell from fever, not something serious.
Right now, this appears to be a simple viral fever, but if it lasts beyond 3 days or worsens, see a doctor. Separately, the previous high APTT needs proper medical evaluation to rule out any bleeding disorder
Hello
This is most commonly due to a viral infection.
The fact that paracetamol brings the fever down for many hours is reassuring.
Dullness and poor appetite during fever are normal. Mild headache can also occur with fever.
🛑Continue paracetamol as per his weight and encourage fluids.
Observe closely.
See a doctor if the fever lasts more than 3 days, goes above 39°C, he becomes very lethargic, has fast or difficult breathing, vomiting, rash, neck stiffness, or if you feel something is not right.
🛑🛑The previously high APTT means a possible clotting factor issue. It is not related to the current fever but should be followed up with a pediatrician or hematologist before any procedures.
Irregular or heavy breathing or heartbeat during activity should be evaluated separately by a pediatrician, especially if it seems unusual or persistent.
I trust this helps Thank you
It’s important to note that while a mild fever without other significant symptoms can often be managed at home, there are certain factors where seeking further medical advice is advisable. In your son’s case, his fever has been consistent for a couple of days, and given his existing medical conditions such as autism and anxiety, it would be prudent to err on the side of caution. Since panadol (paracetamol) is providing temporary relief, it helps eliminate the fever momentarily but doesn’t address potential underlying causes. It’s a good sign, though, that the fever responds well to it.
Since he doesn’t have respiratory, gastrointestinal symptoms, or sore throat, the cause might not be a typical viral infection like the flu or a cold. Children with autism can sometimes find it more difficult to express pain or discomfort, which may make it challenging to pinpoint specific symptoms. Keeping a close watch on his overall behavior, changes in eating, or alterations in sleep patterns could offer more clues. Watch for any worsening of symptoms or new symptoms like rash, persistent headache, significant irritability or confusion, persistent vomiting, or difficulty breathing.
The previously noted prolonged aPTT might be related to a bleeding disorder, which could require follow-up with a pediatric hematologist if you haven’t pursued that yet. While a 55.2 second aPTT can sometimes indicate issues in blood coagulation, it isn’t directly related to fever but may be worth discussing with a healthcare provider soon if there’s a plan in place. Additionally, the irregular heartbeat and breathing you mentioned during activities might warrant a further evaluation because they could relate to his cardiovascular status or be a part of his overall condition. These could be normal variations, but given the context, it would be wise to consult with your child’s pediatrician.
In the meantime, ensure he stays hydrated and continue to monitor his temperature and symptoms closely. If the fever persists beyond three days, or if you’re concerned about any symptom changes, consider taking him for a medical evaluation. A professional might suggest blood tests, including a repeat aPTT if needed, and possibly a chest examination if upper respiratory symptoms develop. Their advice will be tailored to his specific health needs and current condition.
