Source: CDC
Go to resource

Wastewater testing provides an alternative way to rapidly assess SARS-CoV-2 viral exposure among thousands of people, and in a manner that protects privacy. This cutting-edge surveillance tool can boost COVID-19 pandemic response by shedding light on infections among those who do not show symptoms or do not present for testing. Wastewater data can provide an early warning for new waves of infection and identify whether transmission is rising or waning. As of February 2022, the CDC's COVID Data Tracker includes wastewater surveillance data from monitoring SARS-CoV-2 levels in sewage at more than 400 testing sites across the country. Wastewater data allow for more rapid detection of changes in COVID-19 transmission and do not suffer from bias due to testing behavior and test accuracy. Mathematica is providing analytics to translate lab data on sewage biomarkers into policy insights for state and local officials and is also advising federal agencies on standards and best practices for the national system.

Data note:At present, wastewater viral concentrations cannot be used to determine the number of infected people in a community.

Go to resource

This resource, created by Youyang Gu (and independent data scientist), aggregates projections from nearly forty different models and compares them to actual data on COVID-19 cases and deaths. The models are ranked against a "baseline" prediction of lagged actual death data. Model projections are compared at four-week intervals for the entire U.S. and for each state. Code and documentation are provided so these comparisons can be replicated and modified. The UCLA Statistical Machine Learning Group also provides a comparison of its model against several others, at the weekly level, for the entire U.S. and for each state.

This website provides state-by-state data aimed at supporting the decision to reopen the economy. State and county reopening risk levels (coded as elevated, moderate, or reduced) are based on 3 criteria: whether COVID-19 infections are in retreat, whether testing is widely available, and whether hospitals have enough resources.


COVID-19 Hospital Impact Model for Epidemics (CHIME)

Source: Penn Medicine
Go to resource

This open-source tool allows hospitals to project new hospital admissions, ICU admissions, and patients requiring ventilation due to COVID-19. Users input data about their hospital and population and modify assumptions related to the spread of COVID-19. The tool then runs an epidemiological SIR (Susceptible, Infectious, Recovered) model to project the number of new hospitalizations per day. This tool can be used to create best- and worst-case scenarios to assist with hospital capacity planning. Related information includes user documentation (describing the objective of the app, data inputs, and tool outputs), a GitHub repository (developers can contribute to the tool or branch off to modify or expand on the code), and developer documentation.

This tool allows users to project exposures, infections, and hospitalizations due to COVID-19. Users input assumptions about COVID-19 transmission and clinical dynamics and the tool uses an epidemiological SEIR (Susceptible, Exposed, Infectious, Recovered) model to project the spread of COVID-19 and resulting hospitalizations.


COVID-19 Projections

Source: IHME
Go to resource

The Institute for Health Metrics and Evaluation (IHME) projections include state and national information about COVID-19 case counts, hospital/ICU beds, and invasive ventilators available and needed for the projected cases. Projections are shown in graph form across time.

Data note: The validity and usefulness of IHME projections have been called into question; earlier versions of the statistical model did not incorporate transmission dynamics nor other epidemiologic methods. Over the course of 2020, the model improved in accuracy. However, several other models, such as those created by UCLA-suEIR and Columbia, have consistently provided more accurate projections.
