Sources

Medical content on this site is based on published guidance from public health bodies and professional dermatology and paediatric organisations. Occurrence data comes from GBIF. Where sources disagree, we describe the range rather than picking one and stating it as fact.

Occurrence and distribution data

• GBIF — Global Biodiversity Information Facility. Occurrence counts by state and month, filtered to United States records. Snapshot taken 2026-07-27. GBIF aggregates records from museums, surveys and citizen science platforms; individual records carry their own licences, predominantly CC BY 4.0.

How we cite

We do not cite individual studies inline, because this is orientation material rather than a clinical reference — the intent is to help you decide whether something needs attention, and then to point you at care. Anything presented as a number (record counts, months, size ranges) is traceable to the sources above.
