Objective | Sentinel surveillance (community and hospital) | Passive surveillance using RSV laboratory surveillance database |
1) Describe seasonality and trends for RSV | ARI/extended SARI incidence ARI/extended SARI RSV incidence | RSV laboratory-confirmed cases |
2) Measure positivity rates of RSV across different age groups | % of RSV among ARI/extended SARI cases | % of RSV among tested patients |
3) Support the estimation of healthcare burden of RSV | Proportion of hospitalisations associated with RSV ARI/extended SARI incidence ARI/extended SARI RSV incidence | RSV laboratory-confirmed cases Duration of hospitalisation, etc. |
4) Contribute to the overall understanding of the role of RSV in respiratory disease | % of RSV among ARI/extended SARI cases Ratios of RSV positivity compared with other respiratory pathogens | Ratios of RSV detections/cases compared to detections/cases of other pathogens |
5) RSV types and genetic diversity | Genotypic characterisation Phenotypic characterisation | Sequence data stored in an RSV dedicated or general (GenBank) sequence database Existing laboratory databases containing detailed genetic information |
6) Platform and baseline to access impact of immunisation programmes | VE of RSV ARI/extended SARI VE of RSV bronchiolitis (hospital only) RSV incidence before and after implementation (focus on primary target group for vaccination) | If immunisation status is available: VE among different risk groups RSV incidence before and after implementation (focus on primary target group for vaccination) |
RSV: respiratory syncytial virus; ARI: acute respiratory infection; SARI: severe acute respiratory infection; VE: vaccine effectiveness (this term includes the effectiveness of monoclonal antibodies).
