What Is EV-D68? Where Has It Spread?
First of all, this virus is not truly “new.” EV-D68 was first identified in 1962. Although EV-D68 rarely causes disease, the enterovirus family is extremely common. There are over 100 types of enteroviruses, which cause 10-15 million infections annually. (Your children may have experienced hand-foot-mouth disease, which is caused by a type of enterovirus.) Enteroviruses tend to affect infants and children in the summer and fall.
As of the end of September, there have been 443 peoples in 40 states and the District of Columbia with confirmed EV-D68. The children ranged in age from 6 weeks to 16 years. Most of them did not have a fever, and no deaths have been reported. The CDC reports that in the coming weeks, more states will have confirmed cases of EV-D68.
What Are the Symptoms of EV-D68?
The extent of the disease caused by EV-D68 is not fully known. However, in a typical case, symptoms develop rapidly (within hours). The first symptoms are the same as the common cold: cough, runny nose, and sniffles. The hallmark of EV-D68 is wheezing and difficulty breathing. Most children do not have significant problems breathing, and they will typically get better after seven days or so. However, some children develop more severe breathing problems, especially if they have asthma. Kids with wheezing can be treated with medicine given in a breathing treatment (nebulizer). In a few cases in Kansas City, MO, and Chicago, more intensive care was needed, such as oxygen. However, severe cases are rare. It is important to understand that doctors only tested the children who were already very sick, so they found a high proportion of EV-D68 infections in that group. However, they did not test many of the hundreds of children with similar but less severe symptoms. It is likely that most kids with this infection do not get very sick.
Common Sense Protection for Your Kids
There is no specific treatment or vaccine for the virus. Antibiotics will not have any effect at all. The virus seems to be spread through saliva and mucus, either directly from another person, or via household surfaces. Use common sense protection, such as washing hands with soap and water for 20 seconds, disinfecting frequently-touched surfaces such as doorknobs and toys, avoiding sharing utensils, and avoiding rubbing your eyes or mouth with unwashed hands. Avoid exposing children to cigarette smoke, especially if they have asthma. Also, keep in mind that not every child who wheezes when they have this virus will go on to develop asthma.
Let me offer you this piece of advice: Don't panic! Most kids will weather this virus just fine. If you are concerned your infant, toddler, or older child has EV-D68, here are a few things to keep in mind:
- It is very common for kids to get colds and coughs during this time of year, and they usually resolve on their own.
- Antibiotics are not helpful in treating a cold. EV-D68 will look similar to other colds, except your child may have more prominent breathing trouble.
- If she is wheezing or working hard to breathe, call your doctor. She may benefit from breathing treatments. If your child has asthma, use your nebulizer or inhaler treatments the way your doctor instructed. (Ask your doctor how to give an infant a breathing treatment.)
- Also remember that older kids can pass the virus on to your infant, so be sure that everyone is practicing good hand-washing hygiene at home.
Remember, this is general information that applies to most children. It is not meant to substitute for the medical advice of your healthcare provider. Please talk to your pediatrician if you have any specific questions or concerns about your child.
