Do you know what scabies is?

My body is always itchy and no anti-itching ointment works. After a while, blisters appeared on the affected part, and it became more itchy. In addition, the infection rate was very fast, and almost the whole body was covered with small blisters. Is this the so-called scabies?

Scabies (Dermatology and Venereology), Scabies is a contagious skin disease caused by Sarcoma scabiei (scabies). Scabies parasites live in the epidermis of human skin, where they lay eggs and move around, causing papules or small blisters in the prone areas, accompanied by extreme itching. The disease can occur throughout the country without gender differences. It is transmitted through direct or indirect contact, is highly contagious, spreads rapidly, and often spreads among families and groups, with multiple people becoming ill at the same time or one after another. If not properly treated, the condition may worsen repeatedly and become a chronic disease.

Scabies is a skin disease caused by scabies infecting the skin (mechanical damage from digging tunnels and stimulation from their venomous juice secretion). It can be transmitted through sexual intercourse, especially among promiscuous young men and women. The disease spreads rapidly, so it has been listed as a sexually transmitted disease by the World Health Organization. The signs of scabies are intense itching of the skin, and the rash often occurs in the folds of the skin, especially in the pubic area. Scabies is a disease that is spread through close contact. Scabies is highly contagious and is often transmitted from one family to another or from one dormitory to another. Scabies can survive 2 to 3 days outside the human body. Therefore, using clothes, bedding, shoes, socks, hats, and pillowcases used by patients can also be indirectly transmitted. Sexual intercourse is undoubtedly a major route of infection. Scabies is a tiny insect that is invisible to the naked eye. There are countless horizontal wavy wrinkles on the back of the scabies mite, several pairs of rod-shaped bristles and long bristles on the posterior half of the trunk, four pairs of legs on the abdomen, and anus in the center of the posterior edge of the trunk. The palate of scabies is very small, located at the front end of the trunk, half of which is sunken into the trunk. The chelicerae are pincer-shaped, which are suitable for eating the keratin of the skin. Parasitic in the human epidermis.

The life cycle of scabies is divided into four stages: egg, larva, nymph and adult. The eggs are oval, light yellow, with very thin and translucent shells. Often 4 to 6 eggs are gathered together and laid in the tunnel dug by the female insect. They also excrete feces while laying eggs, and after laying eggs, the adults die at the blind end of the tunnel. The larvae hatch from the eggs and live in the tunnels. They soon shed their skin and become adults. After mating with the male adults, the female lays eggs in the tunnel, laying eggs while moving forward, digging tunnels 0.5 to 5 mm every day. If the migration speed is fast, the eggs are scattered in the tunnel; if the migration speed is slow, the eggs are densely packed in the tunnel. Another characteristic of scabies is that they are nocturnal and dormant during the day. Due to the increased activity of scabies at night, the skin often itches severely.
