Can an STD Cause Flu-Like Symptoms?
When we think about sexually transmitted diseases (STDs) or infections (STIs), we often associate them with symptoms like unusual discharge, pain during urination, or sores. However, one lesser-known fact is that some STDs can cause flu-like symptoms. If you’ve recently experienced fever, fatigue, swollen glands, or muscle aches without obvious cause, it’s worth considering whether an STD might be the culprit. In this blog, we’ll explore which STDs can mimic the flu, why this happens, and the importance of seeking timely testing.
At STD Health Check, we offer comprehensive STD testing 7 days a week. Our collection centers are conveniently located throughout the Denver, CO area. Learn more about the testing process below!
STDs That Can Cause Flu-Like Symptoms
Not all STDs cause systemic symptoms like fever or body aches. However, several do, especially during the early stages of infection. Below are some common examples:
1. HIV (Human Immunodeficiency Virus)
HIV is one of the most well-known STDs associated with flu-like symptoms. Within 2-4 weeks after exposure, many people experience acute HIV infection. During this stage, the body begins to produce antibodies to fight the virus, leading to symptoms like:
- Fever
- Fatigue
- Muscle Aches
- Swollen Lymph Nodes
- Sore Throat
These symptoms often resemble the flu or mononucleosis, making it difficult to diagnose based on symptoms alone. Testing is crucial if you’ve recently engaged in high-risk sexual activity.
2. Syphilis
Syphilis, caused by the bacterium Treponema pallidum, can produce flu-like symptoms during its secondary stage. This stage typically occurs weeks or months after the initial infection. Symptoms may include:
- Fever
- Sore Throat
- Swollen Lymph Nodes
- Fatigue
- Muscle Aches
In addition to these systemic symptoms, syphilis may cause a rash, often on the palms of the hands or soles of the feet.
3. Herpes (HSV-1 and HSV-2)
The herpes simplex virus (HSV), particularly during the initial outbreak, can cause flu-like symptoms. These symptoms occur as the body mounts an immune response to the virus and often accompany the appearance of painful blisters or sores in the genital or oral region. Symptoms may include:
- Fever
- Headache
- Muscle Aches
- Swollen Lymph Nodes
4. Hepatitis B and C
Hepatitis B and C are viral infections that can be transmitted through sexual contact. While primarily affecting the liver, early symptoms may mimic the flu, including:
- Fever
- Fatigue
- Muscle Aches
- Loss of Appetite
Why Do Some STDs Cause Flu-Like Symptoms?
Flu-like symptoms from an STD are typically the result of your immune system responding to the infection. When a pathogen enters your body, your immune system activates to fight it, releasing chemicals called cytokines. These chemicals can cause inflammation, fever, and other symptoms that resemble the flu.
The Importance of Early STD Detection
Early detection of an STD can significantly improve your health outcomes. Left untreated, infections like HIV, syphilis, and hepatitis can progress to more severe stages, causing long-term damage to your immune system, liver, or other organs. Testing allows for proper treatment, reducing the risk of complications and preventing the spread of the infection to others.
If you’re experiencing flu-like symptoms without a clear cause– such as a recent viral illness or known exposure to someone with the flu– it’s important to consider the possibility of an STD. Here are some scenarios when testing is essential:
- You’ve had unprotected sex
- You’ve recently had a new sexual partner
- You know or suspect that your partner has an STD
- You’ve noticed other STD symptoms, such as genital sores, unusual discharge, or painful urination
