Fever


I have had a continuous fever for two days, with a temperature of 37.3 degrees Celsius.
I saw a doctor yesterday who prescribed antipyretics, and I took one dose yesterday and another today, but the fever persists.
I also have cold symptoms and a cough.
Do I need to see a doctor immediately? Thank you.

Hello: Based on the symptoms you described, it is not possible to determine whether you need to visit a major hospital.
However, I would recommend that you first consult with the physician you previously saw for an evaluation to check if there are any improvements in other clinical signs or if there is any evidence of a new infection before considering a referral.
Thank you, Chen Meng-Kan.

When dealing with a persistent fever, especially one that lasts for more than a couple of days, it is essential to assess the situation carefully. In your case, you have been experiencing a fever of 37.3 degrees Celsius for two days, along with symptoms such as coughing and cold-like symptoms. While a temperature of 37.3 degrees Celsius is technically considered a low-grade fever, the persistence of the fever combined with other symptoms warrants further evaluation.

Fever is a natural response of the body to infection or illness, and it can be caused by a variety of factors, including viral infections (like the common cold or flu), bacterial infections, inflammatory conditions, or even more serious underlying health issues. The fact that you have already consulted a doctor and received antipyretics (fever-reducing medication) indicates that you are taking appropriate steps to manage your symptoms. However, if the fever persists despite medication, it may be a sign that the underlying cause has not been adequately addressed.

Here are some considerations to help you decide whether to seek immediate medical attention:
1. Duration and Severity of Symptoms: If your fever continues for more than 48 hours without improvement, or if it worsens, it is advisable to seek medical attention. Additionally, if you experience severe symptoms such as difficulty breathing, chest pain, persistent vomiting, or confusion, you should seek emergency care immediately.

2. Underlying Health Conditions: If you have any pre-existing health conditions (such as asthma, diabetes, or a weakened immune system), it is crucial to consult a healthcare provider sooner rather than later. These conditions can complicate infections and may require more aggressive treatment.

3. Response to Medication: If you have taken fever-reducing medications like ibuprofen or acetaminophen and your fever remains unchanged or continues to rise, this could indicate that your body is fighting an infection that requires further medical evaluation.

4. Associated Symptoms: Pay attention to any new or worsening symptoms. For instance, if you develop a rash, experience significant fatigue, or have persistent cough with colored sputum, these could be signs of a more serious infection that needs to be evaluated.

5. Hydration and Rest: Ensure you are staying hydrated and getting plenty of rest. Sometimes, supportive care can help your body recover from mild infections. However, if you feel that your symptoms are not improving or are getting worse, it is better to err on the side of caution and seek medical advice.

In summary, while a low-grade fever can often be managed at home, the persistence of your symptoms suggests that further evaluation may be necessary. If you are unsure, it is always best to consult with a healthcare provider who can assess your condition more thoroughly. If you feel that your symptoms are severe or worsening, do not hesitate to seek immediate medical attention. Your health and safety should always be the top priority.
