How to Identify Fever Symptoms

Fever is the body's natural response to viruses, infections, or other illnesses. It creates an environment that is inhospitable for viruses, leading them to die off within a few days. Sometimes, detecting a fever can be difficult, especially when the cause is a more serious underlying condition. This article will help you recognize a fever and offer guidance on how to monitor whether the fever could be a sign of something more serious.

Monitor your body temperature if you have a thermometer. If your temperature is 39.4°C or lower, you can try treating the fever at home to see if it responds to this care method. If the fever exceeds 40°C, you should call emergency services or go to the hospital immediately for medical care.

Test your skin's temperature if you're unsure. When trying to self-diagnose a fever, it can be difficult to determine if your body temperature is 37°C or 38.4°C. Therefore, it's better to observe other fever signs (as listed below).

• If you're diagnosing a fever in someone else, you can try feeling your own skin temperature and then quickly check the skin temperature of the other person. This comparison can help you determine if they have a fever. If your skin feels much cooler, it means they likely have a fever.
• How accurate is this method? A study found that people who diagnose a fever by touching the skin often "overestimate the severity" of the fever, sometimes by up to 40%.

Check for signs of dehydration. A fever occurs when the body raises its internal temperature to combat harmful agents like infections, viruses, or other serious illnesses. This is a natural defense mechanism. One noticeable result of the body "switching on" its temperature increase is dehydration.

• Signs of dehydration include:
  • Dry mouth
  • Thirst
  • Headache and fatigue
  • Dry skin
  • Constipation
• Dehydration can worsen if vomiting or diarrhea accompanies the fever. In such cases, it’s crucial to drink plenty of water to replace the lost fluids.

Check for muscle pain signs. In many cases, muscle pain is linked to dehydration and can become particularly severe in patients with fever. Note: If the fever is accompanied by back muscle stiffness, it’s important to see a doctor immediately, as this could indicate bacterial meningitis, which could pose a risk of brain damage.

Look for signs of a severe fever. If the fever is 40°C or higher, you may experience several symptoms like flushed skin, dehydration, headaches, muscle pain, and weakness. If you encounter any of the following symptoms or suspect a fever above 40°C, seek medical attention immediately:

• Hallucinations
• Confusion or agitation
• Seizures

Consult a doctor if you're concerned. If the person with the fever is a child or their body temperature exceeds 39.4°C, it’s important to consult a doctor. In most cases, treating a mild fever at home is perfectly acceptable. However, in some cases, the underlying cause of the fever may require professional medical care.

Understand that for mild fevers, some doctors often recommend letting the body fight it off naturally. Fever is the body’s natural response to foreign invaders. Interfering with this response before the body has a chance to combat the infection could prolong the illness or make it harder to identify other accompanying symptoms.

Take over-the-counter pain relievers. Over-the-counter pain relievers, such as NSAIDs (non-steroidal anti-inflammatory drugs), can help alleviate some of the discomfort caused by a fever. Generally, a low dose of NSAIDs can be effective.

• Aspirin is only for adults. Giving aspirin to children can lead to a dangerous condition known as Reye's Syndrome, so it's only recommended for adults.
• Acetaminophen (Tylenol) or Ibuprofen (Advil) can be used for all ages. If your temperature remains high after taking the recommended dose, avoid taking more and consult a doctor.

Drink plenty of fluids. Staying hydrated is essential when you have a fever as it reduces the risk of dehydration, a serious concern when dealing with a fever. It’s best to drink water, but soda and tea (in moderation) may help soothe your stomach. You could also try soup or broths alongside solid, dry foods.
