Wildfires burned millions of acres in California, Oregon, and Washington this year. Record numbers of tropical storms and hurricanes formed in the Atlantic. “Climate change is here. Disasters are here. They are going to be increasing, which is why we want to talk about this and talk about how pediatricians can help and respond to these events,” Scott Needle, MD, said at the annual meeting American Academy of Pediatrics, held virtually this year.

said Dr. Needle, chief medical officer of Elica Health Centers in Sacramento, California. “We can be a positive influence in terms of getting out proactive messaging and keeping people informed.”
The Federal Emergency Management Agency (FEMA) 2019 National Household Survey found that about half of households had an emergency plan. A theme across surveys is that, although households take some steps to get ready for disasters, the public generally “is not as prepared for these events as they really need to be,” Dr. Needle said.
The AAP, the Red Cross, and FEMA are among the organizations that offer planning guides, most of which emphasize three simple things: have a kit, have a plan, and be informed, he said.
To prepare for a disaster, parents might refill a child’s medications ahead of time if possible, Dr. Needle suggested. And during the COVID-19 pandemic, families should add masks, sanitizers, and wipes to their go-bags.
Physicians also can help families by asking how they are coping.

“Smoke from wildfires can blanket large, large areas,” Mark Miller, MD, MPH, said during the presentation at the AAP meeting. “This year, we have seen wildfire smoke from the western states reach all the way to the East Coast. So this impacts your patients and your own families sometimes, regardless of wherever you live.”

Children may be more vulnerable to wildfire smoke because they often spend more time outdoors and tend to be more active. In addition, their ongoing development means exposure to air pollutants could have lifelong consequences, said Dr. Miller, who recently reviewed the effects of wildfire smoke on children.
“Children with asthma should have some information about wildfires built into their asthma management plan,” said Dr. Miller, who is affiliated with Western States Pediatric Environmental Health Specialty Unit (PEHSU) and University of California, San Francisco. Pollutants are associated with respiratory visits and admissions, asthma exacerbations, decreased lung function, and neurocognitive effects. They also may be carcinogenic.
A study in monkeys found that smoke exposure during California wildfires in 2008 was associated with immune dysregulation and compromised lung function in adolescence.
Another study of three cohorts of children in southern California found that air pollutant levels were associated with children’s lung function.
Organizations have provided resources on creating cleaner air spaces during wildfires, including guides to build DIY air filter fans. AirNow.gov provides air quality and fire maps that can inform decisions about school closures and outdoor activities. Communities should prioritize establishing schools as clean air shelters, Dr. Miller suggested.
Studies have found that respirators and medical masks may decrease children’s exposure to smoke. Children should not use face coverings, however, if they are younger than 2 years, if they are not able to remove the face covering on their own or tell an adult that they need help, or if they have difficulty breathing with a face covering. Younger children should be observed by an adult.
During the pandemic, families should be aware that some types of masks are sold only for health care use, many foreign respirators are counterfeit, and cloth masks used for COVID-19 are not suitable for reducing wildfire smoke exposure, Dr. Miller said.
