# Public Health Weekly

> Synthesised from the week's L1 source notes under `../01 Sources/`. The `azimuth-curator`
> fleet role evolves this single note in place each cycle. azimuth reports **recorded disease
> outbreak notifications** — the disease, the place, the case count and the alert level as the
> reporting body published them — never a health prediction, never advice. Every claim links
> to the L1 note it rests on. (Updated from the 2026-08-17 ingest.)

## This week at a glance

- The WHO / CDC outbreak channel carries **156 active outbreak signals** on the 2026-08-17
  pull — **115 watch / 41 alert**, with **no warning-level entry** on the feed's own alert
  bands. The count is unchanged from 08-16 — the first fully flat 24-hour cycle since the slate
  eased from the 08-01 count of 161 ([[disease-outbreaks]]).
- **Measles still dominates the slate by entry count**, holding at **68 of the 156 entries** for
  a second straight day (from 75 of 161 on 08-01). azimuth records each notification in the alert
  band the reporting body assigned it ([[disease-outbreaks]]).
- The **highest single-entry case count remains the 58,000-case Chicken Pox notification in Gaza
  City (watch)**, unchanged since 08-16 and still topping the feed's carried measles leaders.
  Behind it the measles ranks hold at identical figures: **Guatemala City** alert entries at
  **27,145** and **21,700**, **Bangladesh 16,408 (alert)**, **Mongolia 15,475 (watch)**,
  **Bangladesh 14,841 (watch)** and **13,907 (alert)**, **Mexico 11,771 (watch)** / **11,748
  (alert)** and **Dhaka 11,549 (watch)** ([[disease-outbreaks]]).
- The **United States measles entry holds at 2,465 cases (watch)** for a second day (unchanged
  from 08-16; 2,318 on 08-01), its own source summary still recording the 2026 US case total
  above the full-year 2025 total. azimuth records the notification and the reporting body's
  figure and attaches no assessment of trajectory ([[disease-outbreaks]]).

## Reading the week

- The slate held at **156 signals** on 08-17, unchanged from 08-16 and still down from 161 on
  08-01; **no warning-level notification present**, the feed's highest band is "alert" at
  **41 entries**, with 115 in the lower "watch" band ([[disease-outbreaks]]).
- The case-count ranking is unchanged from 08-16: the **58,000-case Chicken Pox notification in
  Gaza City (watch)** still sits above the carried Guatemala City measles pair (27,145 / 21,700
  alert) and the Bangladesh measles 16,408 (alert) entry. Measles still leads the slate by entry
  count (68 of 156); the **US measles entry holds at 2,465 cases (watch)**, its source note still
  recording the 2026 US total above all of 2025. azimuth records each figure as the reporting
  body published it and attaches no assessment of trajectory ([[disease-outbreaks]]).
- azimuth records the notifications as the reporting bodies published them — disease, location,
  case count, alert level — and attaches no assessment of risk, spread or response. A measles-led
  slate of 156 signals with no warning-level entry, topped by a Gaza City chickenpox notification,
  is what the WHO/CDC channel carried on both the 2026-08-16 and 2026-08-17 pulls — zero adds,
  zero departures and zero case-count changes across all 156 matched entries between the two;
  nothing beyond that is inferred ([[disease-outbreaks]]).

## Changelog

- 2026-08-17 — daily-ingest synthesis (2026-W34): the 08-17 pull matched 08-16 exactly — 156 active signals (115 watch / 41 alert; no warning-level entry), measles unchanged at 68 of 156, the 58,000-case Chicken Pox notification in Gaza City (watch) still the highest single entry, and US measles holding at 2,465 (watch). Zero additions, zero departures and zero case-count changes across all 156 matched entries — the first fully flat 24-hour cycle in the tracked series. Updated the at-a-glance and reading sections to record the hold. Observed-only framing held ([[disease-outbreaks]]).
- 2026-08-16 — daily-ingest synthesis (2026-W33): absorbed the 2026-08-07 through 2026-08-16 pulls after a curator gap. The 08-16 feed carries 156 active signals (115 watch / 41 alert; no warning-level entry), easing from 161 on 08-01; measles leads 68 of 156 (from 75). New top single-entry case count: a 58,000-case Chicken Pox notification in Gaza City (watch), now the feed's highest, above the carried Guatemala City measles 27,145 (alert) and 21,700 (alert); a fresh Bangladesh measles 16,408 (alert) also entered. Mongolia 15,475 (watch), Bangladesh 14,841 (watch) / 13,907 (alert), Mexico 11,771 (watch) / 11,748 (alert) and Dhaka 11,549 (watch) held; US measles rose to 2,465 (watch, source note: 2026 US total surpasses all of 2025). Updated the at-a-glance and reading sections; observed-only framing, no health advice ([[disease-outbreaks]]).
- 2026-08-01 — daily-ingest synthesis (2026-W31): absorbed the 2026-07-31 and 2026-08-01 pulls. The 08-01 feed carries 161 active signals (117 watch / 44 alert; no warning-level entry), easing from 165 on 07-30; measles leads 75 of 161 (from 78). The top case-count ranks all carried — Guatemala City measles 27,145 (alert) and 21,700 (alert), Mongolia 15,475 (watch), Bangladesh 14,841 (watch) and 13,907 (alert), Mexico 11,771 (watch) / 11,748 (alert), Dhaka 11,549 (watch) — as did the US measles 2,318 (watch, source note: 2026 US total surpasses all of 2025). Two-day churn minor and confined to small entries: five low-case notifications departed (measles Ghaziabad 129 / Uganda 12 / Colombia 6, Diphtheria Inchiri 19, a zero-case alert) against one zero-case arrival. Updated the at-a-glance and reading sections; observed-only framing, no health advice ([[disease-outbreaks]]).
- 2026-07-30 — daily-ingest synthesis (2026-W31): absorbed the 07-26 through 07-30 pulls after a 5-day curator gap. The 07-30 feed carries 165 active signals (120 watch / 45 alert; no warning-level entry), easing from the prior cycle; measles leads 78 of 165. Top case counts: Guatemala City measles 27,145 (alert) and 21,700 (alert), Mongolia 15,475 (watch), a new Bangladesh 14,841 (watch), Bangladesh 13,907 (alert), Mexico 11,771 (watch) / 11,748 (alert), Dhaka 11,549 (watch). Notable arrivals: US measles 2,318 (watch, source note: 2026 US total surpasses all of 2025), Whooping Cough Santander 3,171 (watch), Measles Punia 2,089 (watch), Measles Peru 1,233 (watch). Rewrote the at-a-glance and reading sections; observed-only framing, no health advice ([[disease-outbreaks]]).
- 2026-07-25 — daily-ingest synthesis (2026-W30): 07-25 pull carries 173 signals (down from 177 on 07-24; 127 watch / 46 alert); no warning-level entry. No id-matched field mutations. Eight entries departed: Measles Pakistan 4,541 (alert) and Measles Dhaka 4,460 (alert) were the largest departures; Polio Sudan 2 (watch) and five zero-case outbreak-news-today entries also left. Five new zero-case CDC entries entered: Unknown Disease US alert, two California Unknown Disease watch, Lassa watch, and E. coli alert (McDonald's Quarter Pounder cluster, Mountain West states). Top case-count ranking unchanged from 07-24; Guatemala City measles 27,145 (alert) remains highest single entry ([[disease-outbreaks]]).
- 2026-07-24 — daily-ingest synthesis (2026-W30): 07-24 pull carries 177 signals (up from 169 on 07-23; 127 watch / 50 alert); no warning-level entry. Bangladesh 120,000-case alert entry departed the feed; highest Bangladesh measles entry now 13,907 cases (alert). Guatemala City gains a new top-entry at 27,145 cases (alert) alongside the carried 21,700-case alert and a 6,209-case alert — three distinct Guatemala City alert entries on this pull. Mongolia 15,475 (watch) and Mexico three entries (11,771 watch / 11,748 alert / 11,111 alert) carried forward unchanged ([[disease-outbreaks]]).
- 2026-07-23 — daily-ingest synthesis (2026-W30): 07-23 pull carries 169 signals (down from 184 on 07-20); no warning-level entry. Bangladesh measles 120,000 cases (alert) unchanged; Guatemala 21,700 (alert) and Mongolia 15,475 (watch) carried forward; Mexico now shows three distinct entries: 11,771 (watch), 11,748 (alert), 11,111 (alert). Bangladesh also carries two additional watch entries (11,549; 10,949) ([[disease-outbreaks]]).
- 2026-07-21 — daily-ingest synthesis (2026-W30): absorbed the 07-18 through 07-20 pulls; the 07-20 feed carries 184 notifications (133 watch / 51 alert), down from 198 on 07-17, with no warning-level entry this pull (the Sudan El Taweisha measles warning dropped off). Measles leads 95 of 184; largest entry measles Bangladesh 120,000 cases; other majors Guatemala City ~21,700, Mongolia ~15,475, Mexico ~11,771 ([[disease-outbreaks]]).
- 2026-07-18 — daily-ingest synthesis (2026-W29): 07-16 and 07-17 pulls identical (198 entries, 144 watch / 53 alert / 1 warning); net change vs 07-15 baseline = -1 entry (Measles/Dhaka 3,065-case alert + Lassa/Iowa watch retired; Unknown Disease/HAI watch added). Warning level unchanged: measles El Taweisha, Sudan, 300 cases, 9 pediatric deaths. Largest alert entry: measles Bangladesh 120,000 cases ([[disease-outbreaks]]).
- 2026-07-15 — first Public Health Weekly cycle (2026-W29): theme un-held (the hold was
  ingest-pending; the WHO/CDC channel is public-domain, surfaced, and carries 21 committed L1
  days). Wrote the at-a-glance and reading sections from the live 2026-07-15 pull: 199 active
  notifications (144 watch / 54 alert / 1 warning), measles leading at 105 incl. the Sudan
  warning-level outbreak (300 cases), alert-level entries clustering in the US (16) and
  Bangladesh (6). Observed-only framing, no health advice ([[disease-outbreaks]]).
