Scabies

The first time you become infected it will take up to six to eight weeks before itching develops. Intense itching is the most common symptom of scabies. During this time, a couple of generations of scabies mites may have had time to develop. The itching is due to a hypersensitivity reaction in the skin. In people who have had scabies before, the itching develops immediately upon reinfection. Even if no symptoms are observed, infected people are likely to spread Scabies to other individuals. A person becomes a disease carrier immediately upon infection.

After becoming infected, symptoms develop gradually. Itching develops over the first few weeks, though initially people may not take note. After a few weeks of infection, the itching becomes more intense and often disturbs the sleep at night.

In addition to the intense itching, various skin changes may be seen on the body as a result of vigorous scratching. This may take the form of scratch marks or an eczema-like rash. Small bumps and blisters occur at an early stage. In some individuals, Scabies tunnels may also become visually apparent.

Scabies tunnels are often found on specific areas of the body:

• On the inside of the wrist
• Between fingers
• Elbows
• Around the navel
• Penis and buttocks
• Nipples in women

In infants, it is easiest to detect the mites on the palms or soles of the feet and on the head. It is extremely uncommon to find Scabies on the head of older children and adults.
