COVID Act Now

a census of infectious disease control strategies put into place to reduce infection acquisitions that are part of an infection in an ecosystem.

control strategy census

diagnostic tests

An organism of a particular biological taxon that is the site of reproduction of an organism of a different taxon.

host organism

Actions of groups of people in response to outbreaks.

behavior

Frequency of interactions between individuals in different settings, at different times...

contact rates

A disease is a disposition (i) to undergo pathological processes that (ii) exists in an organism because of one or more disorders in that organism.

disease

A data set that is about one or more potentially infectious contact processes in a population of host organisms.

data service

viral Infectious disease

 A count of simulated or physical individuals in a population.

Population count

A data set that is about either some mortality rate or the death events themselves of some individuals of a given population of a particular biological taxon.

mortality data

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

vaccine-preventable Disease

A treatment that consists of the administration of antigenic material to stimulate an individual's immune system to develop adaptive immunity to a pathogen.

vaccination
