Table 2.
Attack rate of hepatitis E infection (overall), icteric and anicteric hepatitis E infection, their ratio in children and adults during 2007–2008 epidemic
| Age group, number tested (%) | Children vs. Adults | ||||
|---|---|---|---|---|---|
| Total (N = 638) | Children (≤14 years, N = 330) | Adults (>14 years, N = 308) | P | OR (95% CI) | |
| HEV infection | 0.21 | 1.27 (0.86–1.80) | |||
| Icteric HEV | 21 (3.3) | 6 (1.8) | 15 (4.9) | 0.03 | 2.76 (1.06–7.02) |
| Anicteric HEV | 138 (21.6) | 78 (23.6) | 60 (19.5) | 0.02 | 1.63 (1.1–2.36) |
| Icteric:anicteric ratio | 1:5.6 | 1:12.0 | 1:3.0 | 0.005 | – |
The data show that attack rate of overall hepatitis E infection in children and adults did not differ. Adults more often presented with icteric disease, whereas children more often had anicteric infections
