Scabies: A Comprehensive Guide to Symptoms, Treatment, and Prevention

Scabies mites are tiny parasites that are not visible to the naked eye. They have a life cycle consisting of several stages, including egg, larva, nymph, and adult. Once the female mite burrows into the skin, she lays eggs that hatch within a few days. The larvae then mature into adults and continue the infestation. The entire life cycle takes about two to three weeks, during which the mites multiply and spread to new areas of the skin. This continuous cycle of burrowing, laying eggs, and maturing contributes to the persistence of the infestation and the worsening of symptoms.

The primary mode of transmission for scabies is direct, prolonged skin-to-skin contact with an infected individual. This makes scabies particularly common in households, nursing homes, schools, and other crowded living environments where close physical interactions occur frequently. The mites can also spread through shared bedding, clothing, and furniture, although indirect transmission is less common. Because scabies mites can survive for a short time outside the human body, it is possible for reinfestation to occur if proper decontamination measures are not taken.
