Prevalence and Incidence of Rotavirus

Rotavirus Prevalence: Book Excerpts

Incidence (annual) of Rotavirus:

3 million cases in the USA each year. ... see also overview of Rotavirus.

Incidence Rate:

approx 1 in 90 or 1.10% or 3 million people in USA [Source statistic for calcuation: "3 million cases in the USA each year." -- see also general information about data sources]

Incidence extrapolations for USA for Rotavirus:

3,000,000 per year, 249,999 per month, 57,692 per week, 8,219 per day, 342 per hour, 5 per minute, 0 per second. [Source statistic for calculation: "3 million cases in the USA each year." -- see also general information about data sources]

Prevalance of Rotavirus:

Over 3 million cases of rotavirus gastroenteritis occur annually in the U.S. (Source: FDA Bad Bug Book) ... In the United States alone, rotavirus causes more than 3 million cases of childhood diarrhea each year (Source: excerpt from Stories of Discovery Rotavirus Vaccine Preventing Severe Diarrheal Disease in Infants: NIAID)

Prevelance of Rotavirus discussion:

Rotavirus is the most common cause of severe diarrhea among children, resulting in the hospitalization of approximately 55,000 children each year in the United States and the death of over 600,000 children annually worldwide. (Source: excerpt from Rotavirus: DVRD)

Outbreaks of Rotavirus:

MMWR 48(27):1999 On August 31, 1998, a tetravalent rhesus-based rotavirus vaccine (RotaShield[Registered]*, Wyeth Laboratories, Inc., Marietta, Pennsylvania) (RRV-TV) was licensed in the United States for vaccination of infants. The Advisory Committee on Immunization Practices (ACIP), the American Academy of Pediatrics, and the American Academy of Family Physicians have recommended routine use of RRV-TV for vaccination of healthy infants (1,2). During September 1, 1998-July 7, 1999, 15 cases of intussusception (a bowel obstruction in which one segment of bowel becomes enfolded within another segment) among infants who had received RRV-TV were reported to the Vaccine Adverse Event Reporting System (VAERS).

Outbreaks of group A rotavirus diarrhea are common among hospitalized infants, young children attending day care centers, and elder persons in nursing homes. Among adults, multiple foods served in banquets were implicated in 2 outbreaks. An outbreak due to contaminated municipal water occurred in Colorado, 1981.

Several large outbreaks of group B rotavirus involving millions of persons as a result of sewage contamination of drinking water supplies have occurred in China since 1982. Although to date outbreaks caused by group B rotavirus have been confined to mainland China, seroepidemiological surveys have indicated lack of immunity to this group of virus in the U.S.

The newly recognized group C rotavirus has been implicated in rare and isolated cases of gastroenteritis. However, it was associated with three outbreaks among school children: one in Japan, 1989, and two in England, 1990.

MMWR 47(45):1998: In August 1998, the first live attenuated rotavirus vaccine (Rotashield{registered} {Wyeth Lederle Vaccines and Pediatrics}) was approved for use in infants by the Food and Drug Administration. The Advisory Committee on Immunization Practices has recommended that this vaccine be given as a three-dose schedule to infants aged 2, 4, and 6 months. Since 1991, rotavirus activity in the United States has been prospectively monitored by the National Respiratory and Enteric Virus Surveillance System (NREVSS), a voluntary, laboratory-based system. This report summarizes surveillance data from NREVSS during the 1997-1998 rotavirus season and reviews issues related to rotavirus surveillance that are important for a national rotavirus vaccine program.

MMWR 47(19):1998: On June 24, 1996, the Livingston County (New York) Department of Health (LCDOH) was notified of a cluster of diarrheal illness following a party on June 22, at which approximately 30 persons had become ill. This report summarizes the findings of the investigation, which implicated a deficient water supply system as the cause of an outbreak of diarrheal illness caused by Salmonella serotype Hartford and P. shigelloides. Unfiltered, untreated surface water led to contamination of food during its preparation.

    Rotavirus: Rotavirus - epidemiology
    (The 5-Minute Pediatric Consult)

    • Rotavirus is the most common cause of severe gastroenteritis throughout the world.
    • Rotavirus has a predictable seasonality depending on location:
      • In North America, peaks occur in the late summer in the south, moving northward and eastward.
      • In the northeastern US and Canada, the highest incidence of disease occurs in late winter.
      • In tropical regions, disease occurs throughout the year.
    • Majority of disease occurs in children 6–24 months old.
    • All children have serologic evidence of disease by the age of 4 years.
    • Incubation period is 12 hours to 4 days.
    • Exposure to as few as 200 viral particles can result in disease. The virus can persist on surfaces for prolonged periods of time.
    • Virus can be shed asymptomatically, but shedding may precede disease by 2 days and typically persists for 10 days.

    Rotavirus - incidence

    • Infection accounts for 20–50% of pediatric hospitalizations for gastroenteritis.
    • Causes >500,000 deaths per year in developing countries
    • In the US, rotavirus infection causes at least 50,000 hospitalizations per year and 20–40 deaths per year.

    About prevalence and incidence statistics:

    The term 'prevalence' of Rotavirus usually refers to the estimated population of people who are managing Rotavirus at any given time. The term 'incidence' of Rotavirus refers to the annual diagnosis rate, or the number of new cases of Rotavirus 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. For more information see about prevalence and incidence statistics.
