The Tick Bite That Can Make You Allergic to Red Meat Is Spreading

The state of Arkansas is a hotbed for the spread of alpha-gal syndrome. What do scientists believe is behind the spread of this syndrome, and what can you do to reduce your personal risk? Read on.

Alpha-Gal Syndrome Cases Exploding Across Some Areas of the U.S.

Tick-borne allergy diagnoses are on the upswing across the Mississippi River basin. Arkansas has been identified as one of the nation's hotspots for alpha-gal syndrome over the last several months. The number of suspected cases in the state has almost doubled over the last year, jumping from 1,331 to 2,833. The northwestern corner of the state has been particularly vulnerable, due to its wooded terrain and outdoor lifestyle.

According to data from the U.S. Centers for Disease Control and Prevention (CDC), as many as 450,000 Americans have contracted alpha-gal syndrome since 2010. Experts believe that this number is a severe underestimate, as most states only recently began to count cases.

In addition to the Mississippi River basin, the syndrome is also prevalent across the Hamptons and Martha's Vineyard in the Northeast. Climate experts blame the impacts of global warming for the rapid rise in tick-borne illnesses, as well as the growing numbers of white-tailed deer and shifts in land use over the last several years.

The lone star tick carries the alpha-gal molecule in its saliva, spreading it to its hosts when it attaches. While the disease was once simply known as the "red-meat allergy," its proliferation as of late has prompted scientists to try to learn more about its roots and what to do to prevent it.

Up to 75% of the people who test positive for alpha-gal syndrome experience anaphylactic shock at some point in their journey. While the syndrome is not widely fatal, there have been a few deaths connected to its impacts.

Although the lone star tick is not the only critter that carries this dangerous molecule, this species is able to spread it more easily due to its aggressive nature. The syndrome is named after a sugar known as alpha-gal. These specific ticks are born with these sugar molecules, passing them to humans through bites.

Some people who are exposed to this molecule mount an immune system response when they come into contact with food or products from other mammals. Symptoms range from nausea to vomiting to hives to anaphylactic shock.

One of the biggest concerns facing public health experts now is when the spread will stop. In other words, how many Americans are going to come down with this life-altering condition before we get a handle on it?

Many researchers now believe that most people infected with the alpha-gal antibodies do not go on to develop the allergy. While this is good news in theory, it also means that the syndrome is likely out there in greater numbers than what was once believed.

Arkansas was the first state to make alpha-gal syndrome a reportable disease in 2023 when it required doctors and labs to submit positive test results to the Department of Health. The department then verifies the result and works to identify those who test positive for the antibodies and are actually symptomatic. These efforts are helping scientists to better understand the syndrome.

While the lone star tick had historically been confined to the southern portions of the U.S., climate change is pushing these critters up into the Midwest, the Northeast, and New England. The tick season is also being prolonged because of overall warmer temperatures every year.

The picturesque New England community of Martha's Vineyard had once been largely immune to this problem. However, local health officials have now confirmed an increase from just two cases a few years ago to a whopping 523 cases.

A similar situation has unfolded in nearby Suffolk County in New York. The affluent Hamptons community now has the highest case numbers in the U.S.

Problems Associated with Alpha-Gal

Alpha-gal is misunderstood and underestimated by most people. While people rightfully associate the syndrome with the inability to eat red meat without suffering a reaction, the impacts can be triggered by more than just a juicy steak or a hamburger.

Several regular household products and hygiene essentials contain trace amounts of the alpha-gal molecule. This includes the lubricating strip found on many shaving razors, deodorant, cosmetics, and even bottled water.  

People who have been diagnosed with this syndrome have to be especially careful not to come into contact with any of these molecules, or they could suffer a life-threatening reaction. Third-party apps equipped with barcode scanners have proved to be invaluable for patients wanting to verify that a product is safe. Areas that have high rates of the syndrome are also more likely to have support groups and alpha-gal-friendly restaurants.

Medical care experts also note that the syndrome comes with a wide range of severity. While some people may be able to tolerate trace amounts, other sufferers have to be much more diligent.

How to Lower Your Risk of Alpha-Gal

Being aware of the risks of alpha-gal syndrome is the first line of defense, particularly if you live in a region prone to this affliction. Practicing basic precautions when spending time outdoors can go a long way in reducing your personal risk.

Start with wearing long-sleeved shirts and pants when in wooded areas. Wearing long socks tucked into pants is a good strategy. Experts also advise staying on trails and avoiding rubbing up against brush that could be infested with ticks.

Once inside, perform a thorough check for ticks by removing your clothes and carefully checking the genitals, scalp, and armpits. Taking a shower and drying clothes on high heat adds another layer of protection.

Should you discover a tick, you will want to remove it immediately and carefully using a pair of tweezers. Clean the bite area once the tick has been removed. Do not forget that pets are also prone to ticks, making it important to check them carefully as well.

Alpha-gal syndrome can be diagnosed with a simple blood test. While there is no cure for the syndrome, proper diagnosis and treatment can cause the syndrome to fade away in three to five years.
