Respiratory observations in Wyoming: flu, RSV & COVID-19

A combined respiratory index and separate influenza, RSV and COVID-19 readings from available public-domain CDC surveillance observations. Read the period and provenance before interpreting a level or trend.

This combined respiratory index uses the contributing readings for the Acute Respiratory Illness activity rating (NSSP), emergency-department visit percentages (NSSP) and wastewater viral activity (NWSS). Laboratory positivity has no live adapter and does not contribute to this live reading. Each metric retains its own observation period and availability; a download date does not describe health conditions on that day. You can also compare regional states such as Colorado, Montana, North Dakota and South Dakota.

How to read the Wyoming observations

  • For observations ending Oct 10, 2026, the FluTrack combined respiratory index for Wyoming was Minimal. It summarizes the available surveillance inputs; pathogen-specific readings may be missing. It is not a case count or an influenza-only level.
  • The trend in the share of emergency-department visits was rising (+20%): latest observation compared with the mean of up to three prior observations. This comparison describes that measurement, not a percentage change in the combined index.
  • Highest available pathogen index: Flu (Low). Pathogen indices use different measurement thresholds; this does not identify the most infections or the largest contribution to the combined index.
  • Largest relative increase among available series for the share of emergency-department visits with the same comparison observations: RSV, +50%; latest observation compared with the mean of up to three prior observations. Rankings use the actual uncapped comparisons. Missing, insufficient and zero-baseline series are not ranked.

Dated observations, not real-time counts

Surveillance data is reported with an inherent lag of roughly one to two weeks. FluTrack shows directional trends, not a real-time case count. The trend compares the latest observation with the mean of up to three prior observations of the same measurement. A build or retrieval date does not establish health conditions on that day. Missing data does not mean no illness. For general information only — not medical advice.

Reported observations in Wyoming, in plain English

Week ending Oct 10, 2026 · what the contributing CDC surveillance observations show; not current-day conditions.

  • Overall: The combined respiratory index for Wyoming is minimal for the reported observation period. The share of emergency-department visits was edging up compared with the mean of up to three prior observations. CDC reported the state's broader acute respiratory illness activity as Low.
  • Flu: Influenza accounted for 0.9% of emergency-department visits in the reported period. FluTrack's influenza index was low. The share of emergency-department visits was edging up compared with the mean of up to three prior observations.
  • Emergency visits: Flu accounted for the largest share of visits among these three viruses in Wyoming’s reporting emergency departments (0.9%, against 0.6% COVID-19 and 0.1% RSV) for the reported period. This is not a population case count.
  • Wastewater: Reported wastewater activity indices for Wyoming: COVID-19 1.0 (minimal on FluTrack's scale). These indices are measured against each pathogen's baseline; they do not rank how common the viruses are.
  • Nearby states: Wyoming is tied for the lowest available index level among the 5 other states with usable readings for the same observation period in Wyoming’s HHS region — 1 of 5 compared states is higher.

CDC epidemic trend for COVID-19 in Wyoming

A separate direction-of-change estimate from CDC’s modeling team. It is not part of the FluTrack combined respiratory index and does not change it.

CDC category Not changing

CDC’s model puts the probability that COVID-19 infections are growing in Wyoming at 68%.

Its estimate of the reproduction number (Rt) is 1.01, with a 95% interval of 0.96 to 1.06. Above 1, infections are growing; below 1, they are declining.

Why CDC uses this category
25% to 75% of CDC’s estimated range of Rt values is above 1 (the range spans 1, a mix of growth and decline)

Direction only. CDC says epidemic trends do not reflect the burden of disease and should be read alongside other measures. Estimates are revised as emergency-department data arrive, and can be temporarily off if the share of infected people who visit emergency departments changes, for example with a new variant.

How the COVID-19 signals compare in Wyoming

Each row is a separate measurement with its own period. They are listed together, not averaged or combined into one trend.

CDC estimates this trend from the same NSSP emergency-department data that produce the ED-visit share listed here, so agreement between the two is not independent confirmation.

Wyoming: common questions

What does the Wyoming respiratory index show?

For observations ending Oct 10, 2026, the FluTrack combined respiratory index for Wyoming was Minimal. It summarizes the available surveillance inputs; pathogen-specific readings may be missing. It is not a case count or an influenza-only level.

How is the Wyoming trend compared?

The trend compares the latest available observation with the mean of up to three prior observations of the same measurement. With one prior observation it is a two-observation comparison; with more it is not an ordinary week-over-week change. Insufficient history is unknown, not stable. A zero prior mean has no defined percentage change and is excluded from relative-growth rankings. Capped percentages are labeled and distinguished from the actual comparison. The measurement and dates are shown with the reading.

Where does this Wyoming data come from?

This combined respiratory index uses the contributing readings for the Acute Respiratory Illness activity rating (NSSP), emergency-department visit percentages (NSSP) and wastewater viral activity (NWSS). Laboratory positivity has no live adapter and does not contribute to this live reading. Each metric retains its own observation period and availability; a download date does not describe health conditions on that day. See our methodology and data sources.

How current are the Wyoming observations?

The observation period, source update or publication date when supplied, and retrieval time have different meanings. Weekly publication can describe earlier observation periods; delays and revisions vary by surveillance system. A recent build or retrieval does not establish today’s conditions. Missing, stale or sample data cannot establish a current trend.
