About

How we research

Every step on this site and in the app comes from public guidance we opened and link to, so you can check it yourself.

How a guide is written

From source to page

Each guide goes through the same three steps.

  1. We open the agency pages for the topic and work from what they say today, in their numbers and their order of steps.
  2. The page cites each source where its fact appears, with a link, plus a source list at the end.
  3. When an agency changes its advice, we update the page to match.

Limits

What we don't do

We give standard first aid as the Red Cross and the CDC describe it, and nothing beyond. For anything medical, talk to a doctor, and in an emergency call 911 or your local number.

We make no claims for products, and we describe traditional kitchen preparations as history, with no health claims.

Local authorities always come first. If your county or city says something different from a page here, follow them.

Corrections

Found a mistake?

Tell us through the contact form and pick "A correction" as the topic. Include the page and, if you can, the source that says otherwise. We check it against the source and fix the page when it is wrong.
