The COVID-19 Epidemiology and Monitoring Ontology (CEMO) provides a model for describing, sharing and integrating of COVID-19 epidemiological data for outbreak monitoring and research. This ontology is under development and URIs may not be stable.

The measure (R0) of the transmission potential of a disease such that the infection will be able to start spreading in a population or not. It is the average number of secondary infections produced by a typical case of an infection in a population where everyone is susceptible.
basic reproduction number
Length of time a person may transmit a microorganism; the duration of time a person is infectious
infectious period
A population of organisms that have been infected, but are no longer able to transmit the disease and to acquire the infection again.
recovered cases
DEPRECATED case
A period of time that must elapse before those exposed to or attacked by a contagious disease can be considered as incapable respectively of developing or transmitting the disease.
quarantine period
A count of individuals in a population who meet the criteria of some case definition during some time interval.
number of cases new this week
A data item that is the output of some infection case count and that represents the number of infectious disease cases that ended in death.

A data item that is the output of some infection case count.

A hospital-wide nosocomial infection rate/100 admissions for a given period (month, quarter, or year) is commonly calculated. In this rate, a patient who has two infections is actually counted twice.
hospital-wide nosocomial infection rate per 100 admissions
Represents the proportion of deaths among all infected individuals, including all asymptomatic and undiagnosed subjects.

Hospital-wide patient infection rate/100 admissions are used to avoid the pitfall of multiple infections in the same patient. This rate may be calculated for a given period: month, quarter, and year. In this rate, a patient with two infections is counted only once.

Represents the killing power of a disease, as the ratio of deaths to cases. The time interval is not specified. Not to be confused with mortality rate.

Not all contacts will become infected and the average number of secondary cases per infectious case will be lower than the basic reproduction number.
