I have read that ME might be caused by many viruses but don't see much about the human papillomavirus (HPV). Have any studies been done on HPV and ME? I am curious because 1-2 yrs before I became ill with ME I developed a very severe case of plantar warts on my feet from an exposure at a incredibly dirty water park. Now I am wondering if this infection could possibly be the cause of my ME. In the past I have also developed plantar warts out the blue without any exposure.
