Prevalence and Incidence of Cytomegalovirus
Prevalance of Cytomegalovirus:
50% approximately; almost half of young adults (NIAID) ... see also overview of Cytomegalovirus.
Prevalance Rate:
approx 1 in 2 or 50.00% or 136 million people in USA [Source statistic for calcuation: "50% approximately; almost half of young adults (NIAID)" -- see also general information about data sources]
Cytomegalovirus: Rare Disease
Cytomegalovirus is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Cytomegalovirus, or a subtype of Cytomegalovirus,
affects less than 200,000 people in the US population.

Genital herpes:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Genital herpes is usually caused by infection with herpes simplex virus Type 2, but some studies report increasing incidence of infection with herpes simplex virus Type 1. This disease is typically transmitted through sexual intercourse, orogenital sexual activity, kissing, and hand-to-body contact. Pregnant women may transmit the infection to neonates during vaginal delivery if an active infection is present. Such transmitted infection may be localized (for instance, in the eyes) or disseminated and may be associated with central nervous system involvement.
An estimated 86 million people worldwide are thought to have genital herpes.

Herpes simplex:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
About 85% of all HVH infections are subclinical; the others produce localized lesions and systemic reactions. After the first infection, a patient is a carrier susceptible to recurrent infections, which may be provoked by fever, menses, stress, heat, and cold. However, the patient usually has no constitutional signs and symptoms in recurrent infections.
Primary HVH is the leading cause of childhood gingivostomatitis in children ages 1 to 3. It causes the most common form of nonepidemic encephalitis and is the second most common viral infection in pregnant women. It can pass to the fetus transplacentally and, in early pregnancy, may cause spontaneous abortion or premature birth.
Herpes infection is equally common in males and females. Worldwide in distribution, it's most prevalent among children in lower socioeconomic groups who live in crowded environments. Saliva, stool, skin lesions, purulent eye exudate, and urine are potential sources of infection.

Cytomegalovirus Infection:
Cytomegalovirus Infection - epidemiology
(The 5-Minute Pediatric Consult)
- Increased rates of primary infection are seen in early childhood, adolescence, and childbearing years.
- Transmission may occur by contact with infected respiratory secretions, urine, or breast milk, sexual contact, solid-organ transplantation, or transfusion of infective blood products.
Cytomegalovirus Infection - prevalence
Seroprevalence varies with socioeconomic status; 50% of middle- and 80% of lower-socioeconomic-status adults are seropositive.

Smallpox (Variola Virus):
Smallpox - epidemiology
(The 5-Minute Pediatric Consult)
- The last documented case of endemic smallpox was in Somalia in 1977. The last case in the US was in the late 1940s.
- Smallpox was declared eradicated by the World Health Organization in 1980.
- Historically in unvaccinated individuals ordinary smallpox accounted for 90% of cases and hemorrhagic accounted for 7% of cases. Flat and modified smallpox accounted for the remainder of cases.
- Modified smallpox was rare in unvaccinated individuals but accounted for 25% of cases of disease in vaccinated individuals.

About prevalence and incidence statistics:
The term 'prevalence' of Cytomegalovirus usually refers to the estimated population
of people who are managing Cytomegalovirus at any given time.
The term 'incidence' of Cytomegalovirus refers to the annual diagnosis rate,
or the number of new cases of Cytomegalovirus 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.
