What is Fever?
Fever is defined as a temporary increase in body temperature, often due to an illness. In pediatrics, it is generally considered when a child's body temperature rises above 100.4°F (38°C). Fever is a common symptom in children and can be caused by various underlying conditions, predominantly infections.
When to Seek Medical Attention?
Parents often worry about when to seek medical attention for their child's fever. Immediate medical attention should be sought if:
- The infant is less than 3 months old with a fever of 100.4°F (38°C) or higher.
- The child is between 3 and 6 months old with a fever of 102°F (38.9°C) or higher.
- The child exhibits severe symptoms such as difficulty breathing, persistent vomiting, a rash, or seizures.
- The fever persists for more than 72 hours in a child older than 2 years.
How to Measure Fever?
Various methods can be used to measure a child's temperature:
-
Rectal thermometers: Considered the most accurate for infants and young children.
-
Oral thermometers: Suitable for older children who can hold the thermometer under their tongue.
-
Axillary thermometers: Used under the arm, but less accurate.
-
Tympanic thermometers: Measures temperature inside the ear, convenient but may be less accurate if not positioned properly.
Common Causes of Fever
The most common causes of fever in children are:
- Viral infections: Such as the common cold, flu, or roseola.
- Bacterial infections: Such as ear infections, strep throat, or urinary tract infections.
- Immunizations: Some children may develop a low-grade fever following vaccinations.
- Teething: Can cause a slight increase in temperature but typically not over 100°F (37.8°C).Home Care for Fever
Most fevers can be managed at home with proper care:
- Hydration: Ensure the child drinks plenty of fluids to stay hydrated.
- Rest: Encourage plenty of rest to help the body fight the infection.
- Medications: Over-the-counter medications like acetaminophen or ibuprofen can be used to reduce fever and relieve discomfort. Always follow dosage instructions based on the child's age and weight.Common Myths About Fever
There are several misconceptions about fever that need to be addressed:
- High fever causes brain damage: Fever itself does not cause brain damage. However, extremely high temperatures above 107°F (41.7°C) are dangerous but rare.
- Every fever needs to be treated: Fever is a natural response to infection and helps the body fight off pathogens. Not all fevers need to be treated unless they cause discomfort.
- Cool baths and alcohol rubs: These methods are not recommended as they can cause shivering, which may increase body temperature.When to Use Antipyretics?
Antipyretics like acetaminophen and ibuprofen can be used to reduce fever and alleviate discomfort. However, they should be used judiciously:
-
Use based on symptoms: Only use antipyretics if the child is uncomfortable, in pain, or not drinking well.
-
Appropriate dosing: Always follow the recommended dosing guidelines based on the child's weight and age.
-
Avoid aspirin: Do not give aspirin to children due to the risk of Reye's syndrome, a rare but serious condition.
Preventing Fever
While not all fevers can be prevented, certain measures can reduce the risk:
- Proper hygiene: Encourage regular handwashing to prevent the spread of infections.
- Vaccinations: Keeping up with the recommended vaccination schedule can protect against many fever-causing illnesses.
- Avoiding sick contacts: Minimize exposure to sick individuals, especially during peak seasons for infectious diseases.Conclusion
Fever is a common occurrence in pediatrics and is usually a sign that the body is fighting an infection. Understanding when to seek medical attention, how to measure and manage fever at home, and debunking myths can help parents effectively care for their children. Always consult a healthcare provider if there are any concerns or uncertainties regarding a child's fever.
