Alpha-gal Syndrome (AGS), is an emerging tick-related condition that has become much more prevalent in the last 10 years. As such, we do not have quite as much evidence and experience with it as other tick-related conditions. AGS is not actually an infection, but is rather a food allergy that can develop after being bitten by a tick, usually a lone star tick. Specifically, it is an allergy to foods that are from mammal sources (such as beef, pork, or venison). The allergy usually develops around 4 weeks after the tick bite. Symptoms can be very different from one person to the next, but they usually include hives, stomach upset or pain, and diarrhea. The only real treatment we know of at the moment is avoidance of mammalian food sources, but a lot of research still needs to be done on AGS.
On an anecdotal note, Dr. Tichenor personally knows several people with AGS, but it is so new that he has also had conversations with several doctors from other parts of the country who were not aware of AGS at all.
