Preventing tick bites
Going out on the trails? Then don’t forget to apply tick repellent! Most people don’t know that it only takes a quick tick bite to end up with a condition called alpha-gal syndrome (AGS), a severe allergy to mammalian food and byproducts (beef, pork, dairy, etc.). A few of us Trail Dawgs have this condition. You don’t want to get this! There is no cure. The lone star tick is the main vector and they are rapidly expanding their range. The only way to avoid getting AGS is to prevent getting tick bites. As soon as they bite, they transmit the alpha-gal antigen. Worse yet, tick larvae and nymphs can transmit it too. So this is very different from other tick-transmitted diseases, which typically require a prior blood meal and for the tick to be attached for a while. So relying on old school methods, like doing regular tick checks, showering etc. is not going to keep you safe. You need to prevent getting ticks on you! And check your dogs too!
For tick repellent I recommend picaridin spray (Deet is another option but it destroys plastics). I use a picaridin spray can made by Sawyer that I use on my skin, clothing and shoes. In addition, you should treat clothing, shoes and gear with permethrin. You can also mail in clothing to get treated.
AGS is more than a severe food allergy to beef, pork, dairy etc. It is a syndrome. Apart from common allergic reactions, sometimes anaphylactic, it can lead to hidden inflammation of the brain, arteries, joints, tendons, muscles, etc. It can produce fume reactions. It increases the chance of bee sting allergy. The list goes on. I have had most of this. Other people have other unusual and sometimes unexpected symptoms. Not everyone has it this bad and I don’t want to scare you. Also, not every tick bite results in getting AGS. So don’t be alarmed. Just be cautious. So if you don’t do this already, definitely use an effective tick repellent, and treat clothing and gear with permethrin.
See you on the trails! And please share this post!
