Question
The Wells curve predicts the amount of time it would take for one of these objects to reach a surface, where they can contribute to fomite formation. For 10 points each:
[10h] Name these objects. Sensitivity is improved over traditional quantitative PCR by partitioning template DNA into thousands of these objects in digital PCR.
ANSWER: droplets [accept respiratory droplets; accept digital droplet PCR]
[10e] Face masks and N95 respirators function by blocking droplets containing infectious agents, such as this family of RNA viruses that includes the causative agent of COVID-19.
ANSWER: coronaviruses [or Coronaviridae; accept SARS-CoV-2]
[10m] Mask use can reduce a pathogen’s R-nought, which must be one or higher for it to establish itself as one of these diseases. The common cold is this kind of infectious disease, which is constantly present at a baseline level in a population.
ANSWER: endemic diseases
