Scabies: It is a skin condition caused by mites known as Sarcoptes scabiei. It causes an itchy skin rash and is contagious (spreads from one person to another person). These tiny mites crawl under the skin and live on the skin for months laying eggs, and causing severe itching. Scabies spreads easily throughout the body except for the head. Hence, it should be treated quickly. The most commonly seen symptom is an intensely itchy rash that worsens at night. People who live in nursing homes, university halls of residence, or nurseries are at more risk of spreading scabies from person to person due to close contact.

Pediculosis: It is the infection caused by the parasite, Pediculus humanus. It is an ectoparasite and feeds on blood. It infects the hairy parts of the body, such as the scalp and pubic area. In this condition, lice attach to the scalp and lay eggs at the base of the hair. It can be easily transmitted from one person to another through direct contact. The symptom includes intense itching or scratching at the affected area.
