Table 2. National incidence estimates of rates of hospitalization for severe acute respiratory infection due to influenza in the Lao People's Democratic Republic, by age group, with adjustments to lower and upper bounds for underascertainment of the illness in hospital logbooks, January to December 2016.
| Age group (years) | Rate of influenza-associated SARI hospitalizations per 100 000 population (95% CI)* | ||
|---|---|---|---|
| Corrected rate | Lower bound of estimate | Upper bound of estimate | |
| < 5 | 219 (198–241) | 186 (166–205) | 423 (390–457) |
| 5 to < 15 | 33 (28–39) | 28 (23–33) | 64 (56–72) |
| 15 to < 65 | 14 (13–16) | 12 (11–13) | 28 (25–30) |
| 365 | 106 (91–121) | 90 (76–103) | 204 (183–226) |
| All ages | 48 (44–51) | 40 (37–43) | 92 (87–98) |
CI: confidence interval; SARI: severe acute respiratory illness.
* The multiplier for case underascertainment was 1.44. The estimate of the lower bounds used a multiplier of 1.22, and the estimate of the upper bounds used a multiplier of 2.78.
