Pollen Seasons

Trees in Central Oklahoma trees begin pollinating from mid-September (mountain cedar from the Arbuckle Mountains) through early May (pecan) and late June (pine). There is a second elm season in the fall (late August to October) due to the introduction of lacebark elms and cedar elms to this area. Each of the common tree species (elm, oak, maple/box elder, pecan/hickory, birch, mulberry, juniper, sycamore, pine, cottonwood/poplar, willow) usually pollinate for only a few weeks but added together the season is quite long.

Grasses

Central Oklahoma has two grass seasons. Cool season grasses (blue, fescue, timothy, rye, orchard, and redtop) can begin as early as late February or March but after a month or two they stop pollinating totally. The warm season grasses (which do not cross-react with cool season grasses) such as Bermuda, Bahia, crabgrass, and Johnson begin when the weather becomes warm and do not always stop until a good hard freeze in November.

Weeds

Some weeds pollinate in late spring or summer (dock and plantain), but most begin in late summer and fall. Ragweed pollination begins based on hours of daylight and almost always begin when the days shorten around the middle of August. However, the weeds often continue to pollinate until there is a hard freeze, often in late November.

Molds

We find molds in Central Oklahoma every day of the year unless there is a very hard freeze and/or the ground is covered with snow.
The Oklahoma Allergy & Asthma Clinic is a certified counting station for pollen and mold. We are associated with the National Allergy Bureau and the AAAAI. You can find our counts on the internet at www.oklahomaallergy.com. We supply the local media (TV stations, newspaper and radio) with our counts every day they are done. To learn more about the National Allergy Bureau (NAB) you can go to www.aaaai.org.

Asthma Facts and Figures

Asthma Facts and Figures from the Asthma and Allergy Foundation of America (aafa.org)

May is Allergy and Asthma Awareness Month

What Is Asthma?

  • Asthma is a long-term disease that causes inflammation and swelling of the airways. This results in narrowing of the airways that carry air from the nose and mouth to the lungs.
  • Asthma symptoms include trouble breathing (shortness of breath), wheezing, coughing, and tightness or pain in the chest.
  • Asthma symptoms can be triggered by different things for different people. Allergens, like dust or pet dander, are common triggers. Some people also develop asthma symptoms in response to certain foods or to exercise.

    Asthma can be deadly.

  • There is no cure for asthma, but appropriate treatment prevents asthma attacks and can help you have a better quality of life.
  • Asthma is one of the most common and costly diseases in the United States.

    How Common Is Asthma?

  •  Approximately 25 million people in the U.S. have asthma. This equals about 1 in 13 people.
  • About 20 million U.S. adults age 18 and older have asthma.
  • Asthma rates are highest in Black adults in the U.S.
  • Asthma is more common in female adults than male adults. Around 9.8% of female adults have asthma, compared to 6.1% of male adults.
  • It is a leading chronic disease in children.2 Currently, there are about 5.1 million children under the age of 18 with asthma.
  • Black children are nearly three times more likely to have asthma compared to white children.
  • Asthma is more common in male children than female children. Around 8.4% of male children have asthma, compared to 5.5% of female children.

What Are the Rates of Asthma Attacks in Children?

  • In 2019, 44.3% of children age 18 and younger who had asthma reported having one or more asthma attacks in the past year.
    • About 47.2% of children under the age of 5 with asthma had an attack. 1
  • According to the Centers for Disease Control and Prevention (CDC), asthma attacks in children have declined from 2001 through 2019.
  • Even though asthma is controllable, it is estimated that 50% of children with asthma have uncontrolled asthma.

What Are the Rates of Asthma Attacks in Adults?

  • In 2019, 40.4% of adults age 18 and older who had asthma reported having one or more asthma attacks in the past year.
    • Black adults have the highest rate of asthma attacks in the U.S.
  • According to the CDC, asthma attacks in adults have declined from 2001 through 2019.3 2

How Many People Seek Medical Care for Asthma?

  • In 2018, asthma accounted for 5.8 million doctors’ office visits.
  • In 2018, asthma accounted for 178,530 discharges from hospital inpatient care and 1.6 million emergency department visits.
  • Black people in the U.S. are nearly five times more likely than white people in the U.S. to visit the emergency department due to asthma.

How Many People Die From Asthma?

  • On average, 11 people in the U.S. die from asthma each day. In 2020, 4,145 people died from asthma. Nearly all of these deaths are avoidable with the right treatment and care. In 2020, deaths due to asthma rose for the first time in 20 years.
  • Adults are five times more likely to die from asthma than children.
  • Female adults are more likely to die from asthma than male adults, and male children are more likely than female children.
  • Black people in the U.S. are nearly three times more likely to die from asthma than white people in the U.S.
  • When sex is factored in, Black females have the highest rate of fatality due to asthma. In 2020, Black females were nearly four times more likely to die from asthma than white males.

What Are the Costs of Asthma?

  • From 2008-2013, the annual economic cost of asthma was more than $81.9 billion – including medical costs and loss of work and school days:9 o $3 billion in losses due to missed work and school days
    • $29 billion due to asthma-related mortality o $50.3 billion in medical costs
  • Medical costs for people with asthma are estimated to be $3,266 higher per year (in 2015 U.S. dollars) compared to medical costs for people without asthma.
  • Among children ages 5 to 17, asthma is one of the top causes of missed school days. In 2013, it accounted for more than 13.8 million missed school days.

Why Do Certain Racial or Ethnic Groups Have Higher Rates of Asthma,Asthma Attacks, or Asthma Deaths?

See AAFA’s groundbreaking research report on Asthma Disparities in America. Racial and ethnic differences in asthma frequency, illness, and death are caused by complex factors, including:

  • Structural determinants such as systemic racism, segregation, and discriminatory policies
  • Social determinants such as socioeconomic status, education, neighborhood and physical environment, employment, social support networks, and access to health care
  • Biological determinants such as genes and ancestry
  • Behavioral determinants such as tobacco use and adherence to medicines
  • Social determinants and structural inequities (systemic racism) largely drive disparities in asthma. Factors such as genetics and individual behaviors contribute less to asthma disparities.

Why Do Males and Females Have Different Rates of Asthma?

  • Male children are more likely to have asthma than female children. This trend reverses in adulthood, where female adults are more likely to have asthma than male adults.
  • Some studies suggest this trend reverses because of the effects of testosterone on lung cells. Testosterone, a male sex hormone, has been found to decrease the swelling of the airways in asthma.
