Decent Essays

Histologically, papular lesions show acanthosis, individual keratinocyte necrosis, and basal vacuolization. This is accompanied by a superficial and deep perivascular, lymphohistiocytic infiltrate in the dermis. Lesions in the vesicular stage demonstrate spongiosis with reticular and ballooning degeneration. Multinucleated epithelial giant cells may be seen. Pustular lesions are characterized by epidermal necrosis with numerous eosinophils and neutrophils, many displaying karyorrhexis. Necrosis may extend through full-thickness epidermis with sharp lateral demarcation from adjacent intact epidermis. The associated perivascular infiltrate includes eosinophils and neutrophils in addition to lymphocytes and histiocytes. Petechial lesions demonstrate …show more content…

Data from the African outbreaks suggest that prior smallpox vaccination confers 85% protection from monkey pox; infection may be milder even several years after vaccination, and the incidence of complications may be reduced (Jezek and Fenner , 1988).

The treatment would have to be administered in the very early stages of the disease and it is unlikely that the treatment could be made available in time. In addition, the treatment is not devoid of side effects. 8. Prevention and
