Head lice are small insects around the size of a sesame seed that live on the human scalp. They cannot jump, fly or swim but are spread when people have their heads close together or by sharing combs, brushes and hats.
Cold sores may not be a serious health condition but are painful, annoying, and often embarrassing for those who get them. First exposure to the virus is often in childhood, normally appearing on/near the lip. The virus lies dormant until later in life when triggered to become active and cause cold sores to appear.
Scabies is quite a common skin condition caused by tiny insects (scabies mites) that get under the surface of the skin. The adult female burrows along and lays eggs as it goes. The eggs hatch into larvae that travel to the skin’s surface, mature into adults, mate and repeat the cycle.
