Which condition is associated with a life cycle of 2-3 weeks and causes intense itching?

The condition that is associated with a life cycle of 2-3 weeks and causes intense itching is scabies. Scabies is caused by the infestation of the skin by the Sarcoptes scabiei mite, which burrows into the upper layer of the skin. The life cycle of the mite typically spans 2-3 weeks, beginning with the female mite laying eggs in the skin. The intense itching is primarily a result of an allergic reaction to the mites and their waste products.

This itching commonly intensifies at night and can lead to scratching, which may result in secondary bacterial infections. Understanding the life cycle of scabies is crucial for controlling its spread and addressing infestations effectively. Recognizing the symptoms and how the mite reproduces contributes to effective diagnosis and treatment options.
