Unexplained Fever: When to Seek Medical Attention

Fever of unknown origin (FUO)

Hello, doctor.
I have been experiencing an unexplained fever for three consecutive days, with my temperature ranging between 37.5°C and 38°C.
On the third day, I also developed a headache in the forehead area, but I have had no cough, sneezing, or runny nose during these three days or in the previous week.
In the past week, I visited the Lantern Festival in Linkou and Zhongli.
Given that this is a critical time, I am unsure if I might be a COVID-19 patient, which makes me very anxious, and I am hesitant to go to the hospital for fear that my immune system might weaken and make me more susceptible to contracting COVID-19.
Doctor, is this type of fever common? Do I need to go to the hospital in my situation?

I apologize for the late response.
There are many causes of fever, and if it is simply a fever without any respiratory symptoms, the likelihood of it being related to COVID-19 is actually quite low.
However, a fever lasting more than three days definitely indicates an underlying issue.
It is advisable to wear a mask when seeking medical attention if the fever persists.
Practicing mask-wearing and frequent handwashing makes visiting the hospital safe.

More Info

Experiencing an unexplained fever for three consecutive days, particularly when accompanied by symptoms such as forehead headaches, can be concerning. Your body temperature fluctuating between 37.5°C and 38°C indicates a mild fever, which can be a response to various underlying conditions. Given the current global health climate, it is understandable to be anxious about the possibility of COVID-19 or other infectious diseases.

Fever is a common symptom that can arise from numerous causes, including infections (viral, bacterial, or fungal), inflammatory conditions, autoimmune diseases, and even malignancies. In your case, the absence of respiratory symptoms such as cough, sneezing, or nasal discharge makes it less likely that you are dealing with a typical respiratory infection, including COVID-19. However, it is essential to note that some individuals with COVID-19 may present with atypical symptoms or may not exhibit respiratory symptoms at all.

Given your recent travels to areas where you may have been exposed to infectious agents, it is prudent to consider the following steps:
1. Monitor Symptoms: Keep a close watch on your symptoms. If you develop additional symptoms such as a persistent cough, shortness of breath, loss of taste or smell, or gastrointestinal symptoms, it may warrant immediate medical attention.

2. Self-Isolation: Since you are concerned about the possibility of being infected with COVID-19, it is advisable to self-isolate to prevent potential transmission to others. This is especially important if you have had close contact with individuals who have tested positive for COVID-19.

3. Testing: Consider getting tested for COVID-19, especially if you have any risk factors or have been in contact with confirmed cases. Many healthcare facilities offer testing, and it can provide peace of mind.

4. Hydration and Rest: Ensure you are staying well-hydrated and getting adequate rest. This can help your body fight off any potential infection.

5. Seek Medical Attention: If your fever persists beyond three days, worsens, or if you develop new concerning symptoms, it is crucial to seek medical attention. While it is understandable to be apprehensive about visiting a hospital during this time, healthcare providers are equipped to handle patients safely, and they can provide the necessary evaluations and treatments.
6. Consultation: If you are hesitant to go to a hospital, consider a telehealth consultation with a healthcare provider. They can assess your symptoms and guide you on the next steps without requiring an in-person visit initially.

In summary, while a mild fever can sometimes resolve on its own, persistent fever, especially when accompanied by other symptoms, should not be ignored. It is essential to take your symptoms seriously and seek medical advice if your condition does not improve or worsens. Your health and safety are paramount, and healthcare professionals are there to assist you in navigating these concerns.
