Table 2
Outbreak descriptions in a study of molecular characterization of noroviruses causing acute gastroenteritis outbreaks among US military recruits at 4 basic training facilities, 2013–2023*
Outbreak description† | California | South Carolina | Illinois | Missouri | Total |
---|---|---|---|---|---|
Sporadic | 17 | 5 | 13 | 12 | 47 |
Cluster | 5 | 6 | 4 | 8 | 23 |
Outbreak | 13 | 17 | 6 | 13 | 49 |
Norovirus GI outbreak, no. (%) | 5 (38.5) | 5 (29.4) | 1 (16.7) | 3 (23.1) | 14 (28.6) |
Norovirus GII outbreak, no. (%) | 8 (61.5) | 12 (70.6) | 5 (83.3) | 10 (76.9) | 35 (71.4) |
No. confirmed NoV cases from all outbreaks | 105 | 114 | 57 | 64 | 340 |
Mean cases per outbreak (SD) | 8.1 (5.8) | 6.7 (4.1) | 9.5 (7.0) | 4.9 (2.5) | 6.9 (4.8) |
Combined length of outbreaks, d | 90 | 98 | 56 | 90 | 334 |
Mean length per outbreak, d (SD) | 6.9 (5.0) | 5.8 (+4.9) | 9.3 (8.3) | 6.9 (5.5) | 6.8 (5.5) |
*The 4 facilities were Marine Corps centers in California and South Carolina, a Navy center in Illinois, and an Army center in Missouri. †Sporadic = 1 norovirus case occurring >5 days after another norovirus case at the same location; cluster = 2 norovirus cases occurring within 5 days of each other but >5 days after any other norovirus case at the same location; and outbreak >3 cases occurring >5 days after another norovirus case at the same location.
