CDC's Level 1 notice lists diphtheria outbreaks in Chad, Guinea, Niger, Nigeria, Mali, Mauritania, and Somalia and tells adult travelers to check Td or Tdap booster timing. [1][2]

The scout memo identified a possible online-mainstream gap around diphtheria notice maps a seven-country booster problem, but no verified same-session status URL is attached; this article keeps that online frame unproved and anchors the public record in the cited record.

The reader test for diphtheria notice maps a seven-country booster problem is the public record: if a later source changes that record, the frame changes; if it only changes the argument around the record, the article should not pretend the evidence moved.

That makes CDC the starting point rather than the whole story, because a brief still owes readers the exact object to revisit when the next update arrives and a plain reminder that the most useful follow-up will change the record, not merely the volume of attention around it, especially when the public argument is moving faster than the source trail.

The empty X stack is a boundary: without a verified status URL for diphtheria notice maps a seven-country booster problem, the piece does not claim a social-media consensus.
