Scabies, Lice, Crabs: Symptoms, Diagnosis, Treatment & Complications
Overview
Scabies is caused by the microscopic parasite, Sarcoptes scabei. "Crabs", also known as pubic lice, are caused by Phthirus pubis. Both types of infestations are common worldwide and are thankfully fully treatable.
Transmission

While it is possible to get either condition by sharing bedding, towels or other linens, this is less likely in the case of pubic lice as they require the warmth of a human body to survive.
