Can STDs Come Back?
In most cases, new exposures to STDs that you have had in the past can cause you to get the infection again. Most treatments don't protect you from developing the STD at a future time. If your partner has not been treated, you may pass the infection back and forth. Without the right precautions, you could acquire a second STD or a recurrence of the same infection. In addition, genital herpes virus infections can be recurrent after a single exposure.
Some experts prefer to term STD’s as STIs (sexually transmitted infections). STIs include all infections that can be transmitted sexually. For example, scabies and most recently, Zika virus infections are better classified as STIs.
