Prevalence and Incidence of Allergic bronchopulmonary aspergillosis
Allergic bronchopulmonary aspergillosis: Rare Disease
Allergic bronchopulmonary aspergillosis is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Allergic bronchopulmonary aspergillosis, or a subtype of Allergic bronchopulmonary aspergillosis,
affects less than 200,000 people in the US population.
Ophanet, who are a consortium of European partners,
currently defines a condition rare when if affects 1 person per 2,000.
They list Allergic bronchopulmonary aspergillosis as a "rare disease".

Allergic purpuras:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
The most common identifiable cause of allergic purpura is probably an autoimmune reaction directed against vascular walls, triggered by a bacterial infection (particularly streptococcal infection). Typically, upper respiratory tract infection occurs 1 to 3 weeks before the onset of symptoms. Other possible causes include allergic reactions to some drugs and vaccines, to insect bites, and to some foods (such as wheat, eggs, milk, and chocolate).
Allergic purpura affects more males than females and is most prevalent in children ages 3 to 7. The prognosis is more favorable for children than adults.

Aspergillosis:
Aspergillosis - epidemiology
(The 5-Minute Pediatric Consult)
- Aspergillus species are saprophytic molds that are ubiquitous and worldwide, growing in soil, grain, dung, bird droppings, and decaying plant matter.
- Spores are resistant to desiccation, lightweight, and are easily dispersed in air currents.
- The main route of transmission is via inhalation of airborne spores; person-to-person spread does not occur.
- The incubation period has not been defined.
- Nosocomial outbreaks have occurred when ventilation or heating systems become contaminated, or when large numbers of spores become airborne during building construction or renovation.
Aspergillosis - incidence
The incidence of aspergillosis varies by the type of population. The overall incidence in immunocompromised children is ~0.4%. The incidence in bone marrow transplant patients is higher (4.5%).

About prevalence and incidence statistics:
The term 'prevalence' of Allergic bronchopulmonary aspergillosis usually refers to the estimated population
of people who are managing Allergic bronchopulmonary aspergillosis at any given time.
The term 'incidence' of Allergic bronchopulmonary aspergillosis refers to the annual diagnosis rate,
or the number of new cases of Allergic bronchopulmonary aspergillosis diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
