As close to 22,000 wildland firefighters and support personnel have worked to contain blazes like Oregon’s monster Bootleg Fire, the eastern U.S. was overcome by unusually hazy skies this week.
Nueva York, New Jersey, Pennsylvania and Washington, CORRIENTE CONTINUA., residents looked up in disbelief at a blood-orange sun, filtered by smoke blown in on the jet stream both from the oeste and fires in Canadá.
According to the Environmental Protection Agency (EPA), the number of unhealthy air quality days recorded in 2021 por contaminación monitors nationwide is more than double the number to date in each of the last two years.
With infections from the Pandemia de COVID-19 trending upward once again – especially in Florida, Texas and Missouri – due to the virus’s extremely infectious delta variant, smoke has become even more of a concern.
Los Estados Unidos. Centros de Control y Prevención de Enfermedades (Centros para el Control y la Prevención de Enfermedades) Destacar on its website that recent scientific publications including Conticini et al., 2020 y Travaglio et al., 2020 suggest that air pollutant exposure worsens coronavirus symptoms and outcomes.
Wildfire smoke, a complex mixture of harmful air pollutants also known as PM 2.5, can irritate lungs, cause inflammation, alter immune function and increase susceptibility to respiratory infections, likely including COVID-19.
The agency recommends that Americans get a COVID-19 vacuna to protect from this threat – especially as more people are driven indoors by the smoke.
Además, smoke exposure is linked to both long-term and short-term health issues, including decreased lung function, weakened immune systems, higher rates of flu and even hospitalizations and death.
Según los Centros para el Control y la Prevención de Enfermedades, people with asthma, chronic obstructive pulmonary disease (COPD), heart disease, pregnant women and children are especially at risk, as symptoms can include trouble breathing, wheezing, coughing, asthma attacks, stinging eyes, scratchy throat, runny nose, irritated sinuses, headaches, fatigue, chest pain and increased heart rate.
Air quality alerts were set for cities across the East and at-risk groups were instructed to avoid outdoor activities to reduce exposure, wear N95 masks, keep doors and windows closed and run an air filter to clean inside air.
“It’s certainly unhealthy,” Jeff Pierce, an atmospheric scientist at Colorado State University, said of the air in recent days. “If you have asthma or any sort of respiratory condition, you want to be thinking about changing your plans if you’re going to be outside.”
Americans are advised to create clean living environments, shelter in a cleaner air shelter or cleaner air space if the indoor air quality at home cannot be kept sufficiently clean and wear a fit-tested, NIOSH-approved N95 or P100 respirator, consults local guidelines and monitor the EPA’s Air Quality Indexexternal icon (AQI) forecasts and other resources.
