The D68 virus (Enterovirus D68) is a respiratory illness commonly affecting children. It was first identified in California in 1962 but gained national attention in 2014 when outbreaks were reported across North America.

Here are ten key facts to help you understand the D68 virus.

1. Symptoms

Symptoms of the D68 virus can range from mild to severe. Typical symptoms include fever, coughing, runny nose, sneezing, body aches, and wheezing. Some people may experience difficulty breathing or worsening of asthma symptoms.

In severe cases, hospitalization may be required.

2. Who is at risk

Children and teenagers are the most likely to contract the D68 virus, especially those with a history of respiratory problems like asthma. However, adults can also be infected.

3. Spread of the virus

D68 is spread through contact with respiratory secretions like saliva, mucus, and sputum. The virus can also be detected in stool samples. It spreads easily in crowded areas like schools, daycare centers, and hospitals.

4. Prevention

To prevent the D68 virus, practice good hygiene by washing hands frequently with soap and water. Cover your mouth and nose when coughing or sneezing, and avoid touching your face.

5. Treatment

There is no specific treatment for the D68 virus. Treatment is focused on managing symptoms. Patients may be given medications to reduce fever or ease breathing difficulties.

6. Diagnosis

A diagnosis of D68 is made through a physical examination and testing of respiratory secretions. Blood tests and imaging studies may be performed to rule out other possible causes of symptoms.

7. Testing availability

Testing for D68 is not widely available, and many people with respiratory symptoms may not be tested for the virus.

However, the CDC recommends that healthcare providers consider testing for D68 in patients with severe respiratory symptoms or who are part of a cluster of respiratory illness cases.

8. Outbreaks

Outbreaks of the D68 virus have occurred in several countries, including the United States, Canada, and Europe. The largest outbreak in the US occurred in 2014, with over 1,000 confirmed cases.

9. Connection to AFM

There is a possible association between the D68 virus and acute flaccid myelitis (AFM), a rare condition that affects the nervous system and can cause muscle weakness and paralysis. However, the exact link between the two remains uncertain.
