Enterovirus D68
Enterovirus D68 (EV-D68) is a strain of the Enterovirus genus that mainly affects children. It was first identified in California in 1962 and since then, it has been sporadically reported around the world. The virus can cause respiratory illness, including cold-like symptoms, coughing, wheezing, and shortness of breath. It is transmitted from person to person through close contact with an infected person, or through contact with contaminated surfaces or objects. There is no specific treatment for EV-D68, but most individuals recover without complications. However, some people, especially those with weakened immune systems, may experience severe respiratory illness and require hospitalization. Prevention measures include practicing good hygiene, such as washing hands frequently, covering coughs and sneezes, and avoiding close contact with sick people.
Symptoms of Enterovirus D68
What are the common symptoms of Enterovirus D68?
Common symptoms of Enterovirus D68 include fever, coughing, wheezing, and difficulty breathing. The virus often affects children and can result in mild or severe respiratory illness. Symptoms can range from mild to severe, and in some cases, can lead to hospitalization. Unlike other respiratory viruses such as the flu, Enterovirus D68 can cause symptoms of muscle weakness, paralysis, and numbness.
How does Enterovirus D68 cause respiratory illness?
Enterovirus D68 causes respiratory illness by infecting the respiratory system, specifically the mucous membranes that line the nose and throat. The virus enters the body through contact with respiratory secretions of an infected person, such as saliva or mucous, and can also be transmitted by touching contaminated surfaces. Once inside the body, the virus reproduces rapidly, causing inflammation and damage to the respiratory system, resulting in symptoms such as coughing, wheezing, and difficulty breathing.
What distinguishes Enterovirus D68 from other respiratory viruses in terms of symptoms?
Enterovirus D68 distinguishes from other respiratory viruses in terms of symptoms because of its unusual distribution. It is commonly found in children and may cause respiratory symptoms that are more severe than those caused by other respiratory viruses. Unlike other respiratory viruses that typically cause only upper respiratory symptoms, Enterovirus D68 can cause lower respiratory symptoms, including pneumonia.
What underlying health conditions may increase the risk of severe Enterovirus D68 symptoms?
Underlying health conditions such as asthma, chronic lung disease, and immunodeficiency disorders may increase the risk of severe Enterovirus D68 symptoms. These individuals are more susceptible to respiratory infections in general and may experience more severe symptoms with Enterovirus D68.
Can Enterovirus D68 cause neurological symptoms or complications?
Yes, Enterovirus D68 can cause neurological symptoms or complications. In some cases, the virus can cause muscle weakness, paralysis, and numbness. This complication is more common among people with underlying health conditions or weakened immune systems. Additionally, the virus can cause inflammation of the brain and spinal cord, affecting the central nervous system. However, this complication is rare. Nevertheless, those who experience paralysis or numbness should seek medical attention immediately.
Diagnosis of Enterovirus D68
What tests are commonly used to diagnose Enterovirus D68?
Enterovirus D68 can be diagnosed through a variety of tests.

Common symptoms of Enterovirus D68 include coughing, wheezing, fever, and difficulty breathing. In severe cases, patients may require hospitalization and respiratory support. Healthcare providers should consider the possibility of Enterovirus D68 in patients who present with these symptoms, particularly during outbreaks of the virus.
Is a throat swab or nasal swab more effective for testing for Enterovirus D68?
Nasal swabs are generally considered more effective than throat swabs for testing for Enterovirus D68. This is because the virus primarily affects the lower respiratory tract. However, healthcare providers may use both types of swabs to increase the chances of detecting the virus. It is important to note that testing for Enterovirus D68 is not widely available, so healthcare providers may need to send samples to specialized laboratories for analysis.
Treatments of Enterovirus D68
What are the available treatments for Enterovirus D68?
Treatment options for Enterovirus D68 primarily focus on managing the symptoms that the patient is experiencing. As the virus primarily impacts the respiratory system, treatments may include the use of oxygen supplementation or mechanical ventilation to maintain healthy oxygen levels in the body. There is no specific antiviral medication that is known to be effective against Enterovirus D68, as the virus is known to be highly adaptable to different environments and has few vulnerabilities that can be exploited by medication. However, some antiviral medications may be used as a secondary treatment to help reduce the severity of the symptoms and lessen the duration of the illness.
How is the management of Enterovirus D68 different from other respiratory illnesses?
Managing Enterovirus D68 differs from other respiratory illnesses in several ways. One of the most notable differences is the virus`s rapid spread throughout communities, as it tends to affect children more frequently than adults. Consequently, communities often experience heightened levels of concern and fear in response to this illness. Additionally, Enterovirus D68 tends to cause more severe respiratory symptoms than other respiratory illnesses, which may require more aggressive management interventions to prevent complications like pneumonia.
What measures can be taken to prevent the spread of Enterovirus D68?
There are several measures that can be taken to prevent the spread of Enterovirus D68. These include frequent hand washing, avoiding direct contact with those who are sick, and covering the mouth and nose when coughing or sneezing. It may also be helpful to sanitize frequently touched surfaces, such as doorknobs and light switches, to help prevent the spread of the virus.
Are there any specific guidelines for managing Enterovirus D68 in children?
There are specific guidelines for managing Enterovirus D68 in children. These guidelines include monitoring the patient`s respiratory status and ensuring that they receive adequate oxygen support if necessary. Additionally, children with Enterovirus D68 may require more aggressive management of their symptoms than adults due to the virus`s tendency to cause more severe respiratory symptoms in children.
