Why this verdict (6 steps)
- Date of Event = 2026-04-15 (from case row).
- Admitted 2026-04-13 (HD 1) → DoE on HD 3 → onset = CO (HO would require HD 4 or later).
- Infection Window Period = 2026-04-12 to 2026-04-18; RIT = 2026-04-15 to 2026-04-28.
- Central line inserted 2026-04-12 → in place 4 calendar days on DoE → CLABSI attribution applies.
- Staphylococcus epidermidis is a Common Commensal — LCBI 1 does not apply; evaluate LCBI 2.
- Staphylococcus epidermidis positive on 2 separate occasions within IWP, with 1 qualifying symptom(s) (fever) — **Meets LCBI 2.**

The IWP (2026-04-12 to 2026-04-18) is anchored on the culture date per NHSN PSC Ch.2 — symptoms inside it count toward the surveillance criteria; symptoms outside don't. The Date of Event (DoE) is 2026-04-15 — the urine culture is the earliest criterion element (no qualifying symptom precedes it). The RIT (2026-04-15 to 2026-04-28) is the 14-day window during which no new event of the same type can be reported, anchored on DoE (DoE through DoE + 13).
