14 Chicken PoxOccurs primarily in children, although adults who are not immune can contract it.It is quite contagious and is spread by breathing in infected respiratory droplets or unprotected direct contact with the rash when it has ruptured.In person’s who have had chickenpox, the virus can cause shingles later in life.
15 Clinical presentation The best known symptom of chickenpox is the itchy, red rash that breaks out on the face, scalp, chest, back, and sometimes arms and legs.The rash usually appears about 2 weeks after exposure to the virus and begins as superficial spots.The spots quickly fill with a clear fluid(vesicles), rupture, and turn crusty.The scabs then fall off in a week or two.
16 The rash continues to break out for the first 1 to 5 days, so spots at various stages of development may be present at the same time.A secondary infection of the ruptured rash by bacteria may cause high fever and skin scarring.
20 Treatment Isolate the diseased until the rash crusts. Cool, wet compresses , calamine lotion , antihistamines help to relieve itching.Complications are treated according to symptoms; Secondary bacterial pneumonia is treated with antibiotics.Acyclovir is used for severe varicella infections involving the lungs or the brain and in persons with a depressed immune system.
