• Breakout-search response: Added two fast-turn explainers aimed at current intent spikes: Can hantavirus spread person-to-person? and Cruise ship outbreak: what U.S. readers should know. Both pages separate U.S. CDC baseline risk (rodent exposure) from international Andes-outbreak nuance, with WHO DON + ECDC assessment citations. Wired both into nav, sitemap, home topic guides, and Sources so users can move from headline anxiety to practical prevention pages quickly.

• Gap closure (YMYL / long-tail): Added Treatment and recovery, Diagnosis and testing, Seasonal buildings and RVs, and HFRS and Seoul virus pages; expanded Symptoms with CDC-cited HPS severity language; added four FAQ entries (pets, cure/treatment, diagnosis, HFRS vs HPS) with matching FAQPage JSON-LD; linked Prevention to seasonal guide; extended sitemap, nav, home topic list, and Sources (HFRS brief + clinical overview index). All outbound links are CDC/WHO pages already audited or added in this batch.

• SEO topic guides: Added four prerendered pages targeting common queries (safe rodent-droppings cleanup, HPS incubation/timeline, U.S. deer-mouse/geography framing, HPS vs flu overlap). Updated sitemap paths, primary nav, home “Topic guides” section, and FAQ (+ JSON-LD) with two new Q&As. Sources: CDC hantavirus portal, prevention, healthy-pets cleanup, and HPS clinician brief.

• CDC/WHO link refresh: Replaced retired CDC paths (/about/transmission, /prevention/clean-up under hantavirus, etc.) with current CDC/WHO URLs verified via npm run audit:links. Rodent cleanup now points to healthy-pets/rodent-control/clean-up.html; WHO uses the live health-topics page.

• Initial publication: Scaffolded SvelteKit + mdsvex site with Home, Symptoms, Transmission, Prevention, FAQ, Sources, sitemap/robots, FAQ JSON-LD shell, and link-audit script. Wording is intentionally conservative and CDC-referenced; next reviews should re-open CDC pages before expanding claims.
