As Lyme disease Awareness Month draws to a close, levels of some tick-borne illnesses in Missouri are on the rise.

While Lyme infections in Missouri are not as dramatic as they are in northeastern states, officials said there is still cause for concern. Ticks cause a higher number of human diseases than any other insect in the U.S.

The most common tick related diseases in Missouri are Rocky Mountain spotted fever, ehrlichiosis, tularemia, and Lyme, along with newer viruses such as Heartland and Bourbon. Studies show the frequency of infections are increasing.

Dr. Ram Raghavan, associate professor of veterinary pathobiology at the University of Missouri Veterinary Medical School, said there are several reasons why.

"Some of these suburban areas are built around wooded backyards, and people are interacting with the wild more than they used to be in the past," Raghavan explained. "We are also getting very clever and very accurate in the way we detect diseases, there is increased awareness, not only among practitioners, but also patients."

He pointed out climate change is also making winters warmer and extending tick season. When outdoors experts recommend hikers stay in the center of trails and avoid tall grass and brush. Recommendations also include wearing clothing treated with permethrin or insect repellent containing at least 20% DEET, to check clothing for ticks, showering after being outdoors, then conducting a thorough tick check.

Raghavan noted in addition to the many bacterial pathogens transmitted by ticks, there are also threats from emerging viruses.

"Recently, in the past 10 years or so, a couple of new tick-borne viruses emerged in our area here in the central Midwest," Raghavan outlined. "One of them is called Heartland virus, and another one is Bourbon virus. Heartland and Bourbon viruses can actually kill somebody and there have been a few fatalities that have occurred over the years."

The Missouri Department of Health reports the majority of Heartland virus patients required hospitalization to recover. Bourbon virus is named after Bourbon County, Kansas, where the first U.S. incidence of the disease occurred.

A relatively new condition associated with tick-borne illness is Alpha-Gal Syndrome, when people become allergic to red meat. Raghavan said it is transmitted by the most common tick in the state.

"Meat allergy is a significant problem, and it is transmitted by the tick called the Lone Star tick, which is actually the most abundant tick in our region," Raghavan stressed. "Chances are, if someone is ever going to see a tick on them, it's most likely going to be a Lone Star tick. So we need to be watching out for that."

Ticks cannot fly or jump, nor do they drop from trees. They stay relatively close to the ground where they can access soil moisture which they need to stay alive. After rain, the wet conditions and higher humidity will bring ticks out in greater numbers.

Health disparities in Texas are not only making some people sick, but affecting the state's economy.

A new study shows Texas is losing $7 billion a year because it does not adequately address quality-of-life issues and the health care needs of its lower-income residents.

The research was sponsored by the Episcopal Health Foundation, Methodist Healthcare Ministries of South Texas, and St. David's Foundation.

Brian Sasser, chief communications officer for the Episcopal Health Foundation, said health care includes more than doctors' visits and medication.

"Everything from increasing access to affordable health insurance to investing in under-resourced neighborhoods to give them more options, whether that's exercise options or food options," Sasser outlined. "Look at policy changes that expand health insurance coverage for new moms."

The report breaks down the economic costs of preventable health differences for every Texas county. It found Bexar, Dallas, Harris, Tarrant and Travis counties are losing the most money annually because of health disparities.

The amount of the economic impact depends on the racial and ethnic makeup of the county and the size of its working-age population. Sasser added the report shows Black and Hispanic children are more likely to grow up in neighborhoods with high poverty levels, and higher rates of diabetes and obesity.

"What can we do to work to make sure that the rate of diabetes isn't dramatically different between white households and Black households?" Sasser asked. "That we can make sure the food insecurity isn't dramatically different between someone who makes over $100,000 and someone who makes less than $30,000?"

The Texas Legislature has passed laws to address some of the disparities, including House Bill 12. It extends Medicaid health coverage for 12 months for new mothers, and pays for maternal health services for community health workers and doulas.

There is light at the end of the tunnel for Tennesseans struggling with opioid addiction, as a bill has been passed to increase access to treatment for opioid use disorder at Community Health Centers.

More than 3,800 lives were lost to overdose in the state in 2021, according to the Tennessee Department of Health.

Emily Waitt, policy and advocacy manager for the Tennessee Primary Care Association, said the original bill limited the number of patients nurse practitioners and physician assistants could treat with buprenorphine. The update removes the limitations, allowing more Tennesseans to access medication assisted treatment in their communities.

"It allows NPs and PAs to prescribe to 100 patients at a time, versus 50," Waitt explained. "Basically doubling the number of patients that they can prescribe to."

Community Health Centers serve more than 423,000 patients across Tennessee, regardless of their insurance status or ability to pay. About 7.7% of Tennesseans do not have health insurance.

Libby Thurman, CEO of the Tennessee Primary Care Association, said bringing the treatment to rural health centers expands access to a crucial service for patients who otherwise could not afford it. She noted it is important because people in remote areas often face challenges finding specialists and treatment facilities.

"We really wanted to work on this issue, because we know our Community Health Centers are where patients go for care," Thurman emphasized. "We really believe in an integrated model. So we want to treat the whole person, including if they are struggling with an addiction issue or a substance abuse disorder issue."

Health Centers offer behavioral health care, including counseling, along with treatment. The clinics also focus on creating a supportive network to help patients with family resources, job assistance and community connections.

While Black Maternal Health Week is wrapping up, health disparities for pregnant Black women continues to be an issue.

From April 11-17 this year, the high death rate of Black mothers is in the spotlight. Black women are three times more likely to die from pregnancy-related causes than their white counterparts.

Dr. Patricia Egwuatu, a family practice physician at Kaiser Permanente in Seattle, said racism is at the root of the disparities, which create barriers to health care access. She pointed out lack of access can lead to problems during pregnancy that are preventable or treatable.

"They may exist prior to pregnancy and then it gets worse during pregnancy if it's not managed as part of that maternity care," Egwuatu emphasized. "There are more pregnant women that have chronic conditions such as hypertension, diabetes and heart disease that are amplified during pregnancy."

The White House released a proclamation recognizing Black Maternal Health Week. The Biden administration began recognizing the week in 2021.

Egwuatu noted there are some warning signs any pregnant woman should be aware of and check in with their physician if they develop.

"You might get some changes in your vision that is not your normal. So, like, fuzziness, you can't see as well, or an excruciating headache," Egwuatu outlined. "You could also develop new swelling in your lower extremities that's making it difficult to get around or even new shortness of breath."

Egwuatu stressed physicians also need to recognize the role of racism in medicine. She argued continuous medical education is important for learning how to confront biases, and it is important for doctors to understand how they can provide people with resources.

"Asking the questions about personal barriers," Egwuatu suggested. "Does a patient have issues with getting to work, child care, transportation? What's their education, what's their cultural background and language? And do they even have a cell phone so we can connect with them?"
