Flu in South Dakota Right Now
Last updated:
No current CDC FluView state signal for South Dakota
For current influenza activity, this CDC ILINet feed does not include a weekly South Dakota outpatient ILI percentage. ILINet participation is voluntary, and some state-level rows are not available every week. As a result, we cannot show a current CDC FluView flu level for South Dakota.
What this does NOT mean:
This does not mean South Dakota has zero flu cases or is free of flu activity — it means the state does not share this particular data with the CDC's outpatient surveillance network.
If local experience feels different from the missing CDC row, read why flu numbers and lived experience can disagree.
What to check instead
- Start with the South Dakota health overview for the fastest cross-topic picture of flu, COVID-19, RSV, measles, and MMR coverage.
- Use nearby reporting states as a regional proxy: North Dakota , Minnesota , Iowa .
- Check the national flu map to see whether the broader U.S. trend is still rising or fading.

Frequently Asked Questions
Is the flu going around in South Dakota right now?
We cannot confirm South Dakota's current flu level from CDC ILINet because South Dakota does not submit weekly outpatient flu surveillance data to that network. The best alternatives are the South Dakota statewide overview, nearby states that do report, and the national flu trend page.
Does South Dakota report flu data to the CDC?
South Dakota does not currently report flu surveillance data to the CDC's ILINet (Influenza-like Illness Surveillance Network). ILINet participation is voluntary for states, and not all states submit data. This means we cannot show current flu levels for South Dakota from this source.
Where can I find flu information for South Dakota?
For flu activity in South Dakota, check the South Dakota state health department website. You can also view national flu trends on our flu hub page, or check nearby states that do participate in CDC ILINet reporting.
Where does this flu data come from?
Flu data on Local Health Signal comes from the CDC's ILINet (Influenza-like Illness Surveillance Network), accessed via the Delphi Epidata API. Participation in ILINet is voluntary, and some states — including South Dakota — do not submit data to this surveillance network.
