Reoccurring warts

I had a massive wart outbreak on my hands and feet about 5 years ago but after receiving candida treatment and cryotherapy they went away fairly quickly. About a year ago I had a wart on my foot which was also treated with candida and went away. Now I have developed another wart on my foot. I am wondering why I am getting so many reoccurring warts like this, and if it could indicate that my immune system is weak. I thought it may not be because I did recover after candida but it seems weird to get so many warts in succession like this
