Abstract

One variation of a method for detecting pathogens includes: accessing a timeseries of pathogen data for a pathogen, in a set of pathogens, derived from a series of pathogen samples collected in an environment during a time period; characterizing a pathogen profile, representative of changes in pathogen level of the first pathogen in the environment during the time period, based on the timeseries of pathogen data; accessing a baseline pathogen profile representative of changes in pathogen levels of the set of pathogens in the environment during an initial time period preceding the time period; characterizing a difference between the pathogen profile and the baseline pathogen profile; and, in response to the difference exceeding a threshold difference, selecting a mitigation action configured to reduce pathogen levels of the first pathogen and transmitting a prompt to execute the mitigation action to a user associated with the indoor environment.

Dependent claims

A method comprising:

accessing a timeseries of pathogen data:
derived from a series of pathogen samples collected by an air sampler, installed in an indoor environment, during a first time period;
and
representing levels of a set of microbes;
for each microbe, in the set of microbes, deriving a population curve, in a set of population curves, representing changes in population of the microbe present in the indoor environment during the first time period based on the timeseries of pathogen data;
and
for a first subset of microbes in the set of microbes:
characterizing a first correlation between a first subset of population curves, in the set of population curves, corresponding to the first subset of microbes;
based on the first correlation, predicting a first causal pathway for an increase in populations of the first subset of microbes during the first time period based on characteristics common within the first subset of microbes;
identifying a first mitigation action, in a set of mitigation actions, linked to suppression of the first causal pathway;
generating a prompt to execute the first mitigation action in the indoor environment;
and
transmitting the prompt to a user associated with the indoor environment.
