Answer:
sexual contact
Step-by-step explanation:
Reproductive system infections are caused by various types of agents. They are mainly transmitted by condomless sexual contact with an infected person and usually manifest through wounds, discharge, blisters or warts. These infections are known as Sexually Transmitted Infections. Some of these infections are easy to treat and quickly resolved. Others, however, have more difficult treatment or may remain active despite the patients' feeling of improvement.
