Mi hijo tiene fiebre pero sin otros síntomas

It's every parent's nightmare: your child wakes up fussy, warm to the touch, and clearly not feeling well. You check their temperature, and sure enough, it's high. But there's no cough, no runny nose, no obvious signs of illness. So, what could be causing this fever in your child without an apparent cause?

Fevers in children can be alarming, especially when there's no clear reason behind them. It's important to remember that fever itself isn't an illness; it's a symptom. It signals that the body is fighting off something, even if you can't see what that "something" is.

There are many potential causes for a fever without obvious symptoms in children. Sometimes, it's a mild viral infection that will resolve on its own. Other times, it could be a sign of a more serious underlying condition that needs medical attention.

This article will explore the common causes of fever in children without apparent cause, when to worry, and what steps to take to ensure your child receives the best possible care.

While we'll delve into the potential reasons behind these fevers, it's crucial to remember that this information is not a substitute for professional medical advice. If your child has a fever and you're concerned, it's always best to consult with their pediatrician for proper diagnosis and treatment.

Advantages and Disadvantages of Home Monitoring

When dealing with a fever in your child, you'll often be faced with the decision of whether to manage it at home or seek immediate medical attention. Let's weigh the advantages and disadvantages:

Advantages	Disadvantages
Comfort of your own home Allows the body to fight the infection naturally Avoids potential exposure to other illnesses in a medical setting	Underlying condition may worsen without medical intervention Potential for dehydration if the child isn't drinking enough fluids Increased anxiety for parents if the fever persists or worsens

When to Seek Medical Attention

While most fevers in children are harmless and resolve on their own, it's important to know when to seek medical attention. Contact your child's doctor immediately if:

Your child is under 3 months old and has a rectal temperature of 100.4°F (38°C) or higher.
Your child is between 3 months and 3 years old and has a rectal temperature of 102°F (38.9°C) or higher.
Your child is older than 3 years old and has a fever of 103°F (39.4°C) or higher.
The fever lasts longer than 5 days.
Your child has any of the following symptoms along with the fever:
- Stiff neck
- Severe headache
- Rash
- Difficulty breathing
- Severe abdominal pain
- Unusually sleepy or lethargic
- Irritability or inconsolability

Common Questions and Answers

1. What is the most common cause of fever in children?
Viral infections are the most common cause of fever in children. These infections are usually mild and clear up on their own.

2. Can teething cause a fever?
Teething can cause a slight increase in temperature, but it's usually not high enough to be considered a fever. If your child has a fever while teething, it's likely caused by something else.

3. What is the best way to take my child's temperature?
For infants and young children, rectal temperatures are the most accurate. For older children, you can use a digital thermometer to take their temperature orally, under the arm, or in the ear.

4. Should I give my child medication to reduce their fever?
You can give your child acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) to help reduce their fever and make them more comfortable. However, always follow the dosage instructions on the label and consult with your child's doctor if you have any questions.

5. How can I keep my child comfortable when they have a fever?
Make sure your child gets plenty of rest and fluids. Dress them in light clothing and keep their room cool. You can also give them a lukewarm bath to help bring down their temperature.

6. When can my child return to school or daycare after having a fever?
Most schools and daycare centers require children to be fever-free for at least 24 hours without medication before returning.

7. Can fevers be dangerous for children?
While most fevers are harmless, high fevers can be dangerous, especially for infants and young children. It's important to monitor your child's fever closely and seek medical attention if it gets too high or doesn't come down with medication.

8. What should I do if my child has a seizure with a fever?

Febrile seizures can be scary, but they're usually harmless. If your child has a febrile seizure, stay calm and follow these steps:

Place your child on their side to prevent choking.
Do not put anything in their mouth.
Call 911 immediately.
