Persistent high fever in children: What you need to know!

High fever in children that won’t subside is not only a concern for parents, but it’s also a leading cause of serious illnesses. Let’s delve into the details of the causes and prevention methods when dealing with “persistent high fever in children“.


Causes and Symptoms

Causes of High Fever

Among the various causes of high fever in children, infections top the list as a significant contributor to this condition. Bacteria and viruses, cunning adversaries, have the capability to raise a child’s body temperature. Additionally, conditions such as hypertension also emerge as undeniable factors, especially in young children with a family medical history.

Symptoms of Persistent High Fever in Children

  • Elevated Body Temperature – symptom of persistent high fever in children: One of the most evident symptoms when a child suffers from high fever is an increase in body temperature. Frequently measured using a thermometer, high fever can be the initial sign indicating the invasion of infectious agents or other medical conditions.
  • Runny nose, cough, and other symptoms: Alongside elevated body temperature, children experiencing “persistent high fever” often exhibit symptoms such as a runny nose, cough, sometimes accompanied by a sore throat. These manifestations could be signs of a battle against viruses or bacteria.
  • Other bodily manifestations of illness: Depending on the specific cause, children may also experience other symptoms like headaches, nausea, or even fatigue and overall weakness. This necessitates careful observation and assessment from caregivers and a professional healthcare team.


Care and Treatment

1. Natural Fever Reduction Methods

When a child experiences high fever, implementing natural methods is an essential part of care:

Using cold or warm water – treatment of persistent high fever in children

  • Cold water can be applied through techniques such as cold compresses to specific body areas or by taking a cold bath. This helps rapidly reduce body temperature.
  • Warm water, through bathing or using warm packs, can enhance comfort and alleviate tension.

Rest and hydration

  • Ensure the child gets enough rest to allow the body to recuperate. Reducing physical activity and creating comfortable conditions can help alleviate stress on the body.
  • Maintaining hydration by using a humidifier or placing a damp cloth on the child’s forehead helps reduce temperature and soothe the skin.

Fever-Reducing Medication

When natural methods are insufficient, using fever-reducing medication is a reasonable option, but it should be done correctly:

Appropriate medication and dosage

  • Paracetamol and ibuprofen are commonly used to reduce fever in children. However, attention should be paid to the appropriate type of medication and dosage for each child’s age.

  • Body temperature exceeding safe limits: The clearest sign is when a child’s body temperature surpasses the safe limit. This could be indicative of a severe infection or illness.

  • Deteriorating overall health: Rapid deterioration in a child’s overall health, including dehydration, fatigue, or even loss of consciousness, warrants careful evaluation.

The importance of timely doctor visits

  • Timely doctor visits not only help accurately identify the cause of the fever but also prevent the progression of the illness.
