Early reading. We have captured 3 original posts for this account, below the 8 we require before treating a median as settled. The numbers above describe what we have seen so far, not a finished profile of the account.

A typical post picks up 16 interactions against 1.8M followers, an engagement rate of 0.001%. Posts are seen about 6.0K times each, and 0.268% of those impressions turn into an interaction. That is about 0.331% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.13 posts a day over the last 30 days, though only 13% of days saw any activity at all. Most posts go out around 16:00 UTC, and Wednesday is the busiest day of the week. Of the 3 posts sampled, 100% carry an image or video and 100% link out. The account's strongest tracked post pulled 243 interactions, about 81x its own typical post. Recurring topics include #protectyourhealth, #wildfire. Only 3 original posts have been captured so far, fewer than the 8 posts we want behind a median before treating it as settled. Read the figures above as an early measurement of this account, not as a finished profile of it.

Engagement rate as a share of followers, across the 204,956 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 22,894 times apart and a linear axis would flatten everything below the median into a single point.

Posting timing

This account posts most often around 16:00 UTC, and Wednesday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

Engagement by hour posted, UTCTwenty-four bars, one per UTC hour. Each bar shows how posts published in that hour compare with their own authors' median engagement. Bars above the centre line ran higher than the median, bars below ran lower. A marker flags Busiest hour: 16:00 UTC.

Formats this account uses

Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.

This account's posting mix compared with catalog-wide effects
FormatThis accountCatalog effect95% intervalAccounts behind it
Image or video100% of posts+111%+108% to +115%34K

  • 100% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
  • 100% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts, so a large share of this account's output sits in the weakest bucket we measure.
  • Its average post runs 300 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above the same accounts' other posts.

These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

    This is what American-led #GlobalHealthSecurity looks like. Most infectious disease outbreaks never make the news because CDC teams are on the frontlines detecting and defeating deadly pathogens, stopping threats across borders before they reach the United States. Keeping Americans safe is our number #1 goal. #CrisisToControl

    This is what #GlobalHealthSecurity looks like. In 2025 a dangerous bacterial outbreak spread in Vietnam during peak travel season. CDC experts and local health officials moved fast— detecting the outbreak in one day, containing it to 38 cases, and stopping its spread across borders. Keeping Americans safe is our number #1 goal. #CrisisToControl.

    This is what American-led #GlobalHealthSecurity looks like. In 2025, Uganda reported an outbreak of Ebola. The CDC quickly deployed trained experts to assist Uganda’s national response. Collaborating with local teams, they effectively tracked and contained the outbreak to just 9 cases, preventing it from spreading further, both globally and to the United States. Keeping Americans safe is our number 1 goal. #CrisisToControl

    This is what #GlobalHealthSecurity looks like: Tanzania faced its first-ever outbreak of deadly Marburg virus in 2023. Working closely with Tanzania’s Ministry of Health, CDC detected the virus within 48 hours, stopping it from crossing international borders. Keeping Americans safe is our number one goal. #CrisisToControl
