Enterovirus D68
The emergence of Enterovirus D68 (EV-D68) as a significant public health concern necessitates a comprehensive understanding of its characteristics, transmission, and preventive measures.
Enterovirus D68 is a member of the enterovirus genus, a group of viruses known to cause various illnesses ranging from mild respiratory infections to more severe neurological conditions. First identified in California in 1962, EV-D68 has gained prominence due to its association with acute respiratory illnesses.
Enterovirus D68 and Respiratory Illness
EV-D68 primarily affects the respiratory system, leading to symptoms that can range from mild cold-like signs to severe respiratory distress. Unlike its enterovirus counterparts, EV-D68 is predominantly linked with respiratory issues, making it a unique entity within the enterovirus genus.

Get A Second OpinionSymptoms of Enterovirus D68
The clinical presentation of EV-D68 can vary widely, with symptoms resembling those of the common cold, including:
- Runny nose
- Sneezing
- Cough
- Body and muscle aches
In more severe cases, individuals, particularly children, may experience:
- Wheezing
- Difficulty breathing
- Asthma exacerbations
Enterovirus D68 in Children
Children are particularly susceptible to EV-D68, especially those with pre-existing respiratory conditions like asthma. The virus can exacerbate these conditions, leading to increased hospitalizations and, in severe cases, respiratory failure.
Causes and Transmission of Enterovirus D68
EV-D68 is primarily transmitted through respiratory secretions, such as saliva, nasal mucus, or sputum. The virus spreads via close contact with an infected person or by touching surfaces contaminated with the virus.
Factors Contributing to the Spread
Several factors contribute to the spread of EV-D68, including:
- Close contact in crowded environments, such as schools and daycare centres
- Poor hand hygiene
- Shared use of personal items
Diagnosis of Enterovirus D68
Diagnosing EV-D68 involves collecting respiratory tract specimens, such as nasal or throat swabs. These samples are then tested using molecular techniques, such as polymerase chain reaction (PCR), to detect the presence of the virus.
Challenges in Diagnosis
The similarity of EV-D68 symptoms to other respiratory viruses poses diagnostic challenges, often necessitating the need for specific laboratory tests to confirm the presence of EV-D68.

Book an AppointmentTreatment Options for Enterovirus D68
Currently, there are no specific antiviral treatments for EV-D68. Management primarily focuses on symptomatic relief and supportive care, including:
- Ensuring adequate hydration
- Administering pain relievers and fever reducers
- Using bronchodilators for wheezing and asthma symptoms
Hospitalization and Severe Cases
In severe cases, hospitalization may be necessary to provide oxygen therapy or mechanical ventilation, particularly for children experiencing significant respiratory distress.
Prevention of Enterovirus D68
Preventive measures are crucial in mitigating the spread of EV-D68, especially in high-risk populations like children and individuals with chronic respiratory conditions.
Effective Prevention Strategies
- Good Hand Hygiene: Regular handwashing with soap and water is essential, particularly after coughing, sneezing, or touching potentially contaminated surfaces.
- Respiratory Etiquette: Covering the mouth and nose with a tissue or elbow when coughing or sneezing can reduce the spread of respiratory droplets.
- Disinfection of Surfaces: Regular cleaning and disinfection of frequently touched surfaces, such as doorknobs and toys, can prevent the virus from spreading.
- Avoiding Close Contact: Minimizing close contact with infected individuals and avoiding crowded places during outbreaks can reduce transmission risk.
Role of Vaccination
Currently, there is no vaccine available for EV-D68. However, research is ongoing to develop effective vaccines that can prevent future outbreaks and protect vulnerable populations.
Frequently Asked Questions
1. What are the symptoms of Enterovirus D68?
Symptoms may include respiratory distress, wheezing, and muscle weakness, particularly in children.
2. What causes Enterovirus D68?
Causes are linked to viral infection from EV-D68, which can lead to respiratory illnesses, particularly in children and those with weakened immune systems.
3. How is Enterovirus D68 diagnosed?
Diagnosis typically involves clinical evaluation and laboratory tests to confirm the presence of the virus.
4. What treatment options are available for Enterovirus D68?
Treatment focuses on supportive care, including hydration and symptom management, as there are no specific antiviral treatments.
5. How does Enterovirus D68 relate to respiratory illness?
It is associated with outbreaks of respiratory illness, particularly during summer and fall, affecting children and immunocompromised individuals.
