Is toenail fungus contagious?


Our office continues to be open to all new and existing patients. We use hospital-grade sanitizers and are taking measures to ensure patients maintain social distancing by not having anyone wait in our reception room with others. If you prefer to wait in your car, just give us a call and we will call or text you when we are ready to bring you straight into a treatment room. Our entire staff is wearing masks and we encourage you to do the same.

For those patients who cannot or still wish not to visit the office, we are offering private video telemedicine visits. Simply call the office at 713-785-7881 and ask for an e-visit and we will be happy to get you set up for an immediate appointment. You can also request an appointment through our website.

There was a very effective commercial for Lamisil, a medication to treat toenail fungus, featuring Digger the Dermatophyte which would have you believe that toenaitoenail fungus is contagious and should be treatedl fungus was the next plague. In truth, toenail fungus is contagious, but it is well encapsulated beneath the nail. The risk of transmitting toenail fungus to others is relatively small.


Many people with toenail fungus, however, also have an adjacent fungus infection of the skin, such as athletes foot or tinea pedis. This infection must also be treated and is much more contagious than toenail fungus alone.


The most contagious part of both toenail fungus and athlete's foot is the residual fungus that inhabits the shoes. This fungus will reinfect the skin and toenails even after they are successfully treated with medication. Therefore, in addition to treating the nail and skin with medication, whether topical or oral, it is necessary to ensure the shoes remain free of fungus. In my Houston podiatry practice, we routinely recommend an antifungal spray called Mycomist to disinfect the shoes after they are worn.


If you are concerned that you are suffering from a toenail fungus, contact Houston podiatrist Dr. Andrew Schneider for an appointment. We will discuss the best treatment solution for your condition, resolve the issue, and keep it gone.
