Infection

A potential viral cause for ME/CFS has been suggested for quite some time, and there is evidence indicating that enteroviruses and herpesviruses may be responsible for at least some cases of the illness. Many individuals with ME/CFS have experienced viral infections, leading researchers to investigate the association between ME/CFS and various viruses such as Epstein-Barr virus (EBV), cytomegalovirus (CMV), human herpesvirus (HHV) 6, HHV-7, HHV-8, human parvovirus B19 (B19V), enteroviruses, lentivirus, as well as bacteria like mycoplasma and Borrelia, which causes Lyme disease, and Coxiella burnetii, which causes Q fever. These pathogens can remain dormant in the body and become reactivated.
However, it is important to note that there is no conclusive evidence supporting the idea of chronic viral infection in the majority of ME/CFS cases. Another hypothesis suggests that viruses may trigger the disease and cause immune abnormalities, leaving the immune system dysfunctional and potentially leading to autoimmunity. Viral infections can also trigger an autoimmune response. Additionally, chronic inflammation is often observed in individuals with ME/CFS.
When it comes to external causes, viruses, bacteria, and fungi are considered. In the case of viruses, it is crucial to target the viruses themselves using antiviral drugs or other antiviral therapies, while also focusing on boosting the immune system to eliminate the causative agent. Some studies have shown that antiviral therapy, particularly in cases of Lyme disease falling under the ME/CFS umbrella, has resulted in improvement. However, it is important to note that there is no evidence of any of these therapies leading to a cure or permanent remission.

Symptoms Associated to most common viral infections

Epstein-Barr Virus (EBV):

1. Fatigue:

   • Persistent, unexplained fatigue, often severe and not alleviated by rest.

2. Sore Throat:

   • Recurrent or persistent sore throat, a common symptom during acute EBV infection.

   • Enlarged and tender lymph nodes, especially in the neck and armpits.

4. Fever:

   • Elevated body temperature, often associated with the acute phase of EBV infection.

5. Muscle and Joint Pain:

   • Widespread pain in muscles and joints, similar to symptoms seen in CFS.

6. Headaches:

   • Frequent headaches, including migraines.

Cytomegalovirus (CMV):

2. Fever:

   • Elevated body temperature during the active phase of CMV infection.

3. Muscle and Joint Pain:

Medications:

Antivirals have been extensively studied for the past three decades to determine their effectiveness in treating ME/CFS. These treatments typically involve two different types of antiviral drugs: guanosine analogs like Acyclovir and Valacyclovir, and an immunomodulator called Rintatolimod (trade name Ampligen). Clinical trials on ME/CFS patients have shown varying levels of success with these treatments.
