This isn't exactly a complete question but the stresses go as far as waiting on the package, if its an important one she has to sign for it which means she has to be there otherwise they wont drop it off, if she misses them i believe its three times she has to take the slip they leave to go pick it up at the post office, I don't know if this helped but you weren't exactly specific about what you were asking..
Droplet Precautions are used to prevent the spread of pathogens that are passed through respiratory secretions and do not survive for long in transit. These droplets are relatively large particles that cannot travel through the air very far. They are transmitted through coughing, sneezing, and talking.
