COVID-19 Monitor: Interactive Dashboard for Communities and Workplaces

COVID-19 Monitor — What to Watch Today (Cases, Variants, Guidance)

Staying informed about COVID-19 requires focusing on a few key indicators that signal changing risk and when to adjust behavior or policies. Below are the most important items to check daily, why they matter, how to interpret them, and practical steps to take based on what you find.

1. Case counts and trends

• What to check: Daily new cases per 100,000 people (local and broader region), 7-day average, and whether cases are rising, stable, or falling.
• Why it matters: Case trends show community transmission speed and help predict near-term pressure on healthcare and workplaces.
• How to interpret:
  • Rising 7-day average: increased transmission; consider tightening precautions.
  • Stable/declining: lower immediate risk, but watch for lagging indicators (hospitalizations).
• Actionable steps: Increase mask use in indoor public spaces when cases spike; limit large gatherings; test after exposure.

2. Hospitalizations and healthcare capacity

• What to check: COVID-19 hospital admissions, ICU occupancy, and percent of inpatient beds in use locally.
• Why it matters: Hospitalizations lag cases but directly measure healthcare strain and severity.
• How to interpret:
  • Growing hospitalizations: greater severe disease or vulnerable populations affected.
  • High ICU occupancy: potential for reduced care for other conditions.
• Actionable steps: Delay nonurgent medical procedures if capacity is stressed; employers should prepare contingency staffing plans.

3. Test positivity and testing availability

• What to check: Percent positive tests (7-day average) and ease of getting PCR/antigen tests.
• Why it matters: High positivity suggests many infections are undetected and testing is insufficient.
• How to interpret:
  • Positivity >5% (or trending upward): likely undercounted cases; increase testing and caution.
  • Low positivity: testing capacity adequate relative to spread.
• Actionable steps: Increase access to rapid tests for symptomatic people and close contacts; use tests before events.

4. Variants and sequencing data

• What to check: Prevalence of known variants of concern locally, signs of new variant emergence, and vaccine-escape or transmissibility data.
• Why it matters: Variants can change transmissibility, severity, and vaccine effectiveness.
• How to interpret:
  • Dominance of a more transmissible variant: expect faster spread and possibly more cases.
  • Evidence of immune escape: consider booster recommendations and updates to vaccines.
• Actionable steps: Follow updated vaccination guidance; increase surveillance and genomic sequencing support where possible.

5. Vaccination and booster coverage

• What to check: Percent of population fully vaccinated, booster uptake, and coverage in high-risk groups (elderly, immunocompromised).
• Why it matters: Vaccination reduces severe disease, hospitalizations, and deaths. Coverage gaps predict vulnerability.
• How to interpret:
  • Low booster coverage among high-risk: higher risk of severe outcomes in a surge.
  • High overall coverage: community-level protection, but local pockets still matter.
• Actionable steps: Prioritize outreach to unvaccinated and under-vaccinated groups; make boosters easily accessible.

6. Public health guidance and policy updates

• What to check: Local public health advisories, mask mandates, travel notices, and testing recommendations.
• Why it matters: Guidance translates data into actions for businesses, schools, and individuals.
• How to interpret: Changes often follow shifts in cases/hospitalizations or new variant information.
• Actionable steps: Align workplace and school policies with local health advice; communicate changes clearly and quickly.

7. Wastewater surveillance and syndromic signals

• What to check: Wastewater viral load trends and increases in syndromic surveillance (e.g., flu-like illness in emergency departments).
• Why it matters: These provide early warning of rising community transmission before clinical testing data.
• How to interpret: Rising wastewater signals often precede case increases by days to weeks.
• Actionable steps: Ramp up testing and public messaging when wastewater signals rise.

Quick decision guide

• If cases AND hospitalizations are rising: ramp up masking, limit high-risk gatherings, expand testing
