Smallpox physical examination

This is a chart that describes a patient with a a generalized vesicular or pustular rash. It is also based upon the risk of smallpox to the patient.



Presentation
The first general symptom of smallpox will be small red spots on places such as the face, mouth, etc. These spots will eventually turn into vesicles and then pustules. A rash will then begin forming on the skin around the face which will eventually move down the body to the feet. After having the rash for approximately 3 days, raised pustules will begin to form. These pustules will be filled with an opaque fluid with a depression in the middle. This is one of the signature characteristics of smallpox.

For diagnosing smallpox, there are some major and minor criteria needed during the physical examination.

Major

 * On any singular part of the body, there needs to be lesions in the same stage of development
 * Characteristic pustules:
 * Well circumscribed and round
 * Confluent or they will have a depression in the middle
 * Fever occurring approximately 1-4 days before rash begins.
 * The fever is usually > than 102 degrees Fahrenheit.
 * With fever, have at least one of the following symptoms.
 * Abdominal pain
 * Chills
 * Backache
 * Headache

Minor

 * Patient appears toxic or near death
 * Initial lesions will be on the face, forearms, and oral palate
 * There will be lesions on the palms and soles
 * Most of the lesions will be on the distal extremities and face (greatest concentration)
 * Evolution of rash from macules to papules to pustules to scabs is a slow process
