Symptoms Commonly Seen for Persistent NonPolio Enteroviral Infections 
Listed here are common symptoms of persistent non-polio enteroviral infection. This list is from observations made by Dr. John Chia in his Infectious Disease Medical Practice in Torrence, CA.

• Respiratory and/or gastrointestinal symptoms or just flu-like symptoms (fevers, body ache, headache etc.). Few virus infections present with both respiratory and GI symptoms.
• Upper respiratory tract symptoms such as runny and stuffy nose, sinus congestion and pain, sore throat, ear pain, difficulty in swallowing, loss of smell or taste.
• Upper and lower gastrointestinal symptoms such as nausea, indigestion, reflux, abdominal bloating, upper and lower abdominal pain, cramps, constipation alternating with diarrhea.
• Sudden weight loss due to significant stomach problem or decreased caloric intake, or weight gain due to inactivity.
• Numbness in the limbs, muscle twitching and spasms. Some experience facial tingling and numbness.
• Many types of headaches.
• Bone, muscle, and/or joint pain. Foot pain is quite common.
• Chest pain, palpitations and tightness
• Cough, shortness of breath, wheezing
• Low blood pressure
• Heart arrhythmia (irregular heartbeat) or tachycardia (rapid heartbeat)
• Intermittent low grade fever, chills and night sweats.
• Reproductive irregularities and pain.
• Prostate issues and pelvic pain.
• Blurred vision.
• Herpangina (blisters or ulcers over the roof of the mouth). Ulcers may form in the mouth, throat and for females the vaginal/cervix area.
• Recurring yeast or bacterial infections due to a weak immune system.
• Adrenal surge or dysfunction. High cortisol levels or low cortisol levels.
• Psychological problems, anxiety, or depression.
• Mental fatigue when trying to concentrate on tasks. Cognitive issues are very common as are short-term memory problems.
• Sleep disturbance.
• Seizures are rare but do occur.
• Vitamin and mineral deficiencies. Many become anemic.
• Swollen Lymph nodes in the neck and in the armpits
• Rash
• Organs that can be affected by enteroviruses: heart, pancreas, lungs, liver, spleen, colon, ovaries, testicles, epididymis, thyroid, muscles, skin and the central nervous system.
• Enteroviral infections can trigger dormant viruses to reactivate, such as HHV6, Epstein Barr Virus, CMV, and chickenpox– all herpes viruses.
• Children can show symptoms, but parents may not recognize them especially if they are intermittent.
• Children can have many of the same adult symptoms – a flu-like illness, fever, mouth ulcers, abdominal pain, loss of appetite, a rash, headaches, leg pain and weakness, muscle twitching, reflux, cognitive dysfunction and perhaps heart pain and arrhythmias. A diagnosis of chronic fatigue syndrome/myalgic encephalomyelitis in children is possible after three months of illness.
• An enteroviral infection should be suspected if the same symptoms recur every month.
