“ Scabies Life cycle Diagnosis, Treatment And Control” Said Adan animal.discovery.com

 Skin contact with infected person.  Infected persons who have no itching can pass the mite on to others  Scabies is usually not transmitted via clothing or bedding its very uncommon (the usual wash cycle can be used when these items are laundered)

In routine scabies, a single mite is seen. Eosinophilic spongiosis may be present (H&E, 400X). Court

 Classical sites of scabies rash...  between fingers  wrists  auxiliary areas  female breasts (particularly the skin of the nipples)  the umbilical area  penis and scrotum  buttocks  inside of legs  ankles

 Definite diagnosis - a definite diagnosis is made by taking skin scrapings from burrows and identifying the mites, their eggs or faeces by microscopy  Presumptive diagnosis - it is often difficult to find burrows and obtain suitable specimens, therefore presumptive diagnosis relies on history and clinical appearance

 Use a scabicide for the treatment of scabies  Permethrin (Elimite) -- In 5% cream.

 Ivermectin (Mectizan, Stromectol) -- Binds selectively with glutamate-gated chloride ion channels in invertebrate nerve and muscle cells, causing cell death.

 Promote good surveillance of new residents  Observe for rashes on arrival at the home, then at 3 weeks and at 6 weeks  Maintain a high level of suspicion if patients present with undiagnosed skin rashes  Families are treated all at the same time.
