Table 3. National estimated number of hospitalizations 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) | Population of Lao People's Democratic Republic PDR, 2015 | Number of influenza-associated SARI hospitalizations (95% CI) | ||
|---|---|---|---|---|
| Corrected | Lower bound of estimate | Upper bound of estimate | ||
| < 5 | 681 983 | 1496 (1 349–1642) | 1267 (1 135–1400) | 2888 (2 661–3115) |
| 5 to < 15 | 1 397 815 | 465 (386–545) | 394 (322–467) | 898 (784–1013) |
| 15 to < 65 | 4 137 333 | 593 (531–654) | 502 (446–558) | 1144 (1 052–1236) |
| 365 | 275 097 | 291 (250–332) | 247 (209–284) | 562 (503–621) |
| All ages | 6 492 228 | 3097 (2 880–3313) | 2623 (2 431–2816) | 5978 (5 625–6331) |
CI: confidence interval; Lao People's Democratic Republic PDR: Lao People's Democratic Republic; 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.
