FOODBORNE NORWALK VIRUS

American Journal of Epidemiology, 1982
On December 6, 1979, three luncheon banquets were served in a New Jersey restaurant. Thirty-eight of 41 members (92.7%) of the first group became ill as did 25 of 31 members (80.6%) of the second group. None of 12 members of the third group were ill. Illness consisted primarily of diarrhea (76%), nausea, (73%), vomiting (67%), cramps (46%) and fever ...

Norwalk virus infection in Venezuela

Annals of Tropical Medicine & Parasitology, 1998
The presence of antibodies against Norwalk virus (NV) was studied in sera from different Venezuelan populations, using an enzyme immuno-assay (EIA) based on recombinant NV protein. Antibodies to NV were found in 47%-53% of urban subjects from Caracas, 83% of rural subjects from the west of the country, and 73%-93% of Amerindian subjects.

Structure of Norwalk virus

1996
Norwalk virus is the major cause of epidemic viral gastroenteritis of humans. Attempts to grow this virus in laboratory cell lines have been unsuccessful. However, the Norwalk virus capsid protein, when expressed in insect cells infected with a recombinant baculovirus, spontaneously assembles into virus-like particles.

Detection of Norwalk Virus or Norwalk-like Virus Infections in Finnish Infants and Young Children

Journal of Infectious Diseases, 1994
Norwalk virus (NV) and Norwalk-like viruses are important causes of epidemic nonbacterial gastroenteritis in older children and adults. Serologic responses to NV of 154 Finnish infants and young children participating in a rotavirus vaccine study were examined by ELISA with a recently available baculovirus-expressed recombinant NV capsid protein.

Hospital Outbreak of Norwalk-Like Virus

Infection Control & Hospital Epidemiology, 1997
Abstract An outbreak of gastroenteritis caused by Norwalk-like virus occurred in two areas of the hospital: area 1, consisting of three adjacent and interconnected wards, with mostly elderly patients; and area 2, an acute ward in a separate building with elderly patients.

Norwalk Virus Outbreak at a College Campus

Southern Medical Journal, 1986
An epidemic of nonbacterial gastroenteritis affected nearly 100 students at a college campus in Jefferson County, Alabama. The outbreak closely resembled food poisoning, since there was a rapid occurrence of multiple cases within a short period. Vomiting occurred in 79% and diarrhea in 64%; fever was uncommon. We found a significant association between

A hospital outbreak due to Norwalk virus

Journal of Hospital Infection, 1994
An outbreak of diarrhoea and vomiting began at a hospital for the elderly on the 25 October 1991. The symptoms and pattern of spread suggested a viral aetiology from a point source. Electron microscopy confirmed the presence of Norwalk virus. The first wave of illness affected 37 patients and 28 staff. Secondary cases occurred on all wards.

Completion of the Norwalk virus genome sequence

Virus Genes, 1996
Norwalk virus (NV) is the prototype human calicivirus, and causes epidemic outbreaks of acute gastroenteritis. The sequence and predicted genome organization of NV and a NV-like virus [Southampton virus (SHV)] suggested they are similar viruses at the nucleotide and amino acid level, although SHV was reported to be antigenically distinct from NV.

[Norwalk virus and Noro virus].

Rinsho Biseibutsu Jinsoku Shindan Kenkyukai shi = JARMAM : Journal of the Association for Rapid Method and Automation in Microbiology, 2005
Norwalk virus and Noro virus are members of the Caliciviridae. These viruses are morphological similarity in each other and shows small round structure. These viruses also are well known as main pathogens of acute infectious gastroenteritis. Clinical features include an incubation period of 24 of 48 hours and illness period of 18 to 72 hours with ...

Epidemiology of Norwalk Gastroenteritis and the Role of Norwalk Virus in Outbreaks of Acute Nonbacterial Gastroenteritis

Annals of Internal Medicine, 1982
Outbreaks of Norwalk gastroenteritis, which may involve persons of all ages, occur during all seasons and in various locations. Waterborne, foodborne, and person-to-person modes of transmission have been described, and secondary person-to-person transmission is common. Outbreaks generally end in about 1 week; longer outbreaks occur only when new groups
