Table
Percentage of diarrhea hospitalizations attributable to rotavirus for countries in different World Bank income groups, 1986–1999 and 2000–2004
| Income group | Median % (interquartile range) of diarrhea-associated hospitalizations due to rotavirus |
|
|---|---|---|
| 1986–1999 | 2000–2004 | |
| Low | 20 (16–27) | 39 (28–45) |
| Low middle | 25 (20–33) | 40 (32–43) |
| High middle | 31 (25–42) | 38 (35–45) |
| High | 34 (28–38) | 44 (40–50) |
| Total* | 21 (17–28) | 39 (29–45) |
*The overall median was calculated by taking a weighted average of the median rotavirus detection rate for each income group. The weights applied to each group corresponded to that group's proportion of global diarrheal deaths: 85% for low-income countries, 13% for low-middle–income countries, 2% for high-middle–income countries, and <1% for high-income countries.
