How many days, weeks, or years is it from the time HPV gets into your skin cells until you can see a wart?

Venereal warts. The latency or dormant period of viruses is extremely variable and subject to outside influences such as the host's well-being - in times of "stress when the host can't cope as well (when an individual's immune system is "stressed" or weakened) viruses may seem to "flare." viruses may remain "dormant" for years. That is why we need to remain healthy with a good diet, exercise and plenty of rest.
