rubella antibodies in your blood .

30
Q

  2. Pregnant women may be treated with antibodies
    called hyperimmune globulin that can fight off the

contact with skin lesions.
?

39
Q

Chickenpox Pathogenesis

?

A

The virus in the respiratory mucosa infects macrophages
and monocytes; at this stage, there are no symptoms. • The virus spreads from the lungs to lymphocytes and
monocytes and to the reticulo-endothelial system. • The virus travels to the skin, mouth, conjunctiva, respiratory
tract and, indeed, to epithelial sites throughout the body. • Here the virus infects epithelial sites forming papule
containing multinucleated cells with intracellular
inclusions. • Spreading of the disease can be from virus in the
respiratory tract (by a cough) or from contact with ruptured
papule on the skin containing infectious virus.

Q

forming papule
containing multinucleated cells with intracellular
inclusions.

Q

Chickenpox Diagnosis?

3. Culture of the virus from the lesions (a difficult procedure). • 3- Detection of specific antigens. • 4- The characteristic appearance of cells  in biopsy specimens of
skin lesions can also be used.
42
Q

Parents will be told to keep children out of school and daycare to
prevent spread of the virus. Infected adults will also be told to
stay home.
