Travel medicine data changelog

Our travel medicine scope and destination guidance are not set-and-forget. Every prescribing boundary, dose, and country recommendation traces to a published source, and we review them on a schedule and whenever CDC guidance changes. This is the public record of what changed, when, the source, and why. The machine-readable version of the current scope lives at /data/travel-medicine-scope.json and the country matrix at /data/travel-malaria-by-country.csv.

Clinician audit of the travel scope. Corrected the malaria referral wording so that mefloquine is referred for neuropsychiatric and cardiac screening, separate from primaquine and tafenoquine, which need G6PD testing. Added breastfeeding to the malaria referral, drug-allergy screens across motion sickness, altitude, and malaria, and a clarification that epinephrine remains first-line for anaphylaxis in pregnancy.
Added explicit malaria regimens (doxycycline continued 4 weeks after travel; atovaquone-proguanil 7 days after) and the epinephrine 30 kg weight threshold to the published scope.
Pinned the service area as a closed list of 11 states, with New York explicitly excluded, so it cannot be misread.
Published a visible scope table and an entity schema graph on the travel medicine page, and 10 destination pages (Peru, India, Mexico, Costa Rica, Tanzania, Guatemala, the Dominican Republic, Bali, Kenya, and Thailand), each checked against CDC destination guidance.

Sources: CDC Yellow Book, CDC Travelers' Health destination pages, Wilderness Medical Society 2024 altitude guidelines, and current DailyMed labels. Reason: a multi-model clinical review of the scope before the destination pages were built from it.

Launched the travel medicine vertical. Five services: motion sickness, altitude sickness, traveler's diarrhea, malaria prevention, and epinephrine auto-injector refills, each as a flat $45 asynchronous visit with the prescription sent to the patient's own pharmacy.
Set the prescribing boundaries: doxycycline and Malarone for malaria (referring mefloquine, primaquine, and tafenoquine), no vaccines, and clear referral to a travel clinic for anything that needs a shot or an exam.

Sources: CDC Yellow Book and DailyMed labels. Reason: initial build of the service line.
