COMMON SIGNS AND SYMPTOMS OF CHICKENPOX AND SMALLPOX

A

•Cutaneous bullous eruptions all over the body

B •Itchy skin rash

C•Fever•Flu-

like symptoms

SMALLPOX

caused by either of two virus variants

Variola major

Latin names Variola or Variola vera

Variola minor.

an infectious disease unique to humans

SMALLPOX

Smallpox localizes in small blood vessels

skin mouth throat

In the skin it results in a characteristic maculopapular rash and, later, raised fluid-filled blisters.

V. minor causes a milder form of disease which kills about 1% of its victims.

V. major produces a more serious disease and has an overall mortality rate of 30–35%.

Transmission

Transmission occurs through inhalation of airborne variola

usually droplets expressed from

the oral nasal pharyngeal mucosa

an infected person

Signs and symptoms of smallpoxMajor smallpox criteria

Fever (>101°F) precedes the rash by

2 to 4 days.

Malaise, head and body aches.

Classic small lesions:

deep-seated,firm/hard vesicles or

Lesions in same stage of

development on any one part of the

body.

Minor smallpox criteria

Begins on face which spreads to

extremities.

First lesions on the oral mucosa, face

or forearms.

Slow evolution of lesion:

macules to papules to pustules.

Lesions on the palms and soles.

Patient appears toxic or moribund.

1•Is a highly

contagious illness caused by primary infection with varicella zoster virus

2

•Chickenpox is an airborne disease spread easily through coughing or sneezing of ill individuals or through direct contact with secretions from the rash.

THE RASH OF CHICKENPOX AND SMALLPOX ON DIFFERENT DAYS

On day 3, the rash of each disease are very similar

On day 2, the differentiation is impossible

THE RASH OF CHICKENPOX AND SMALLPOX ON DIFFERENT DAYS

By day 5, the differentiation is clear.

In the chickenpox there are papules, vesicles and pustules present.

However, the smallpox lesions are at the same stage of development.

small rash

big rash

THE RASH OF CHICKENPOX AND SMALLPOX ON DIFFERENT DAYS

By day 7, most of the chickenpox lesions have already formed scabs,

in the smallpox not yet formed.

On day 10, the chickenpox scabs have fallen off, while the smallpox scabs are just beginning to form.

Treatment

mainly consists of easing the symptoms

TreatmentThere is no actual cure

while the immune system clears the virus from the body

The condition resolves by itself with in a couple of weeks

It is important

•To maintain good hygiene

•Daily cleaning of skin with warm water

to avoid secondary bacterial infection

Use anti-itching creams and lotions
