Items corresponding to entire populations or subpopulations. Might be geographically or temporally temporally limited.

population

The CHIME (COVID-19 Hospital Impact Model for Epidemics) App is designed to assist hospitals and public health officials understand hospital capacity needs as they relate to the COVID-19 pandemic. CHIME enables capacity planning by providing estimates of total daily (i.e. new) and running totals of (i.e. census) inpatient hospitalizations, ICU admissions, and patients requiring ventilation. These estimates are generated using a SIR (Susceptible, Infected, Recovered) model, a standard epidemiological modeling technique. The output of the model can be visualize on the App or download in a CSV format. The code source is available on GitHub: https://github.com/CodeForPhilly/chime.

CHIME (COVID-19 Hospital Impact Model for Epidemics)

A species of BETACORONAVIRUS causing atypical respiratory disease (COVID-19) in humans. The organism was first identified in 2019 in Wuhan, China. The natural host is the Chinese intermediate horseshoe bat, RHINOLOPHUS affinis.

Vaccine preventable diseases are those infectious diseases that can be prevented by vaccination

vaccine-preventable Disease

Vaccine-Preventable Disease

Projections of outbreak behavior into some future time, determined relative to a defined starting point. Might include retrospective projects or projections for current activitiy (known as "now-casting").

forecasting

Forecasting

Forecasts based on SIR (Susceptible, Infected, Recovered) models or any of the many variants of this basic famework.

compartmental models

Compartmental Models

A respiratory tract infection caused by a virus. Viruses represent the most common causes of upper and lower respiratory tract infections and include rhinoviruses, influenza viruses, parainfluenza viruses, and respiratory syncytial virus.

viral respiratory tract infection

Viral Respiratory Tract Infection

Minute infectious agents whose genomes are composed of DNA or RNA, but not both. They are characterized by a lack of independent metabolism and the inability to replicate outside living host cells.

Viruses

Information about capacity, including hospital beds, PPE supplies, nursing home capacity, testing sites, therapeutics, etc.

health system capacity

Health System Capacity

An organism of a particular biological taxon that is the bearer of an infectious dispositions towards an organism of a different particular biological taxon.
