Hemorrhagic varicella is a condition most commonly observed in immuno-compromised or immuno-suppressed patients. In many cases , it has been found that hemorrhagic varicella may  affect normal adults as well as children.

Some of the clinical syndromes associated with hemorrhagic varicella include febrile purpura and malignant chickenpox with pupura. It has been found that post infectious pupura is also associated with hemorrhagic varicella disease.

Pupura fulminans and anaphylactoid pupura also lead to this fatal complication. There are varying courses of the syndromes, as febrile pupura is the most benign form of all syndromes associated with hemorrhagic varicella.

In this case the disease may not lead to fatal complications. However in the case of malignant chickenpox and pupura there will be many grave complications associated with the disease. The mortality rate has been found to be very high above seventy percent. According to experts, the etiology of hemorrhagic chickenpox disease in not known.

This is a fatal disease associated with the inhalation of airborne respiratory droplets from the hemorrhagic varicella virus infected host. In this case high level of viral titers would be found in the characteristic lesions associated with the disease.

Thus, it has been found that transmission of the fatal illness may also be associated with direct contact with the chickenpox lesions.
