Worried Father


Dear Doctor Hsieh: Today my daughter had a fever and went to the clinic, where they said it was an enterovirus infection.
What is an enterovirus? Are there any complications associated with it? Thank you, a concerned father.

Dr. Xie Degui reply Pediatrics


Hello: I'm not sure if what you mentioned is correct; could it be EBV? If you still have a fever, I recommend seeing a doctor for confirmation.

More Info


The EC virus, or Enterovirus, is a group of viruses that can cause a variety of illnesses, particularly in children. Enteroviruses are known for their ability to spread easily, especially in crowded environments such as schools and daycare centers. They are primarily transmitted through respiratory droplets, direct contact with an infected person, or contact with contaminated surfaces.
Symptoms of an enterovirus infection can vary widely, ranging from mild to severe. Common symptoms include fever, sore throat, runny nose, cough, and body aches. In some cases, children may also experience gastrointestinal symptoms such as vomiting and diarrhea. More severe manifestations can include rashes, hand-foot-and-mouth disease, and in rare cases, neurological complications such as viral meningitis or encephalitis.
In your daughter's case, if she has been diagnosed with an enterovirus infection, it is essential to monitor her symptoms closely. While most children recover without any complications, some may develop more severe symptoms that require medical attention. Complications can include dehydration due to vomiting or diarrhea, respiratory distress, and in rare cases, myocarditis (inflammation of the heart muscle).
It is important to note that enterovirus infections are typically self-limiting, meaning that they resolve on their own without the need for specific antiviral treatments. Supportive care is usually recommended, which includes ensuring that your child stays hydrated, rests adequately, and manages fever with over-the-counter medications like acetaminophen or ibuprofen, as advised by a healthcare provider.

If your daughter’s symptoms worsen or if she exhibits signs of severe illness—such as difficulty breathing, persistent high fever, or signs of dehydration (like dry mouth, lack of tears, or decreased urination)—it is crucial to seek medical attention promptly.
In summary, while enterovirus infections can cause a range of symptoms and potential complications, most children recover fully with appropriate care. Keeping an eye on her symptoms and maintaining good hygiene practices, such as frequent handwashing and avoiding close contact with sick individuals, can help prevent the spread of the virus. If you have any further concerns or if her condition changes, do not hesitate to consult with her pediatrician for personalized advice and treatment options.
