Alpha-Gal Syndrome: Experts Raise Awareness of Tick-Borne Illness
Health professionals are raising concerns about Alpha-Gal Syndrome (AGS), a tick-borne illness, and urging Australians to be aware of its potential symptoms. While still relatively rare in Australia, experts are noting an increase in reported cases and are highlighting the importance of early diagnosis and treatment.
AGS is triggered by a carbohydrate called alpha-gal, found in the saliva of certain ticks, primarily the Paralysus tick found on the east coast of Australia. Individuals who are bitten by an infected tick can develop an allergic reaction to mammalian meat, such as beef, pork, and lamb, as well as dairy products. The reaction can range from mild skin rashes and digestive issues to severe anaphylaxis, a life-threatening allergic reaction.
Symptoms typically appear 3-6 hours after consuming alpha-gal containing products. This delayed onset can make diagnosis challenging, as individuals may not immediately associate their reaction with the food they ate. Common signs include hives, itching, swelling, abdominal pain, nausea, vomiting, and diarrhoea. In severe cases, it can lead to difficulty breathing and a drop in blood pressure.
“It’s crucial for people who experience unexplained allergic reactions, particularly after eating mammalian meat, to seek medical advice,” said a leading allergist. “Early diagnosis is key to managing the condition and preventing severe reactions. Patients need to be educated about avoiding alpha-gal containing foods and carrying an EpiPen if they are at risk of anaphylaxis.”
There is currently no cure for AGS, and management focuses on avoiding trigger foods and treating allergic reactions as they occur. Medical professionals emphasize the importance of accurate diagnosis, which often involves allergy testing and careful review of patient history. Further research is underway to better understand the prevalence and long-term effects of AGS in Australia.
The best preventative measure is to avoid tick bites. This includes wearing long sleeves and pants when walking through grassy or wooded areas, using insect repellent containing DEET, and performing tick checks after spending time outdoors. If a tick is found, it should be removed carefully using fine-tipped tweezers, grasping it as close to the skin as possible and pulling straight out. Do not twist or jerk the tick.
