AGE WELL: On average, as this chart reveals, chronic diseases increase with aging, which makes the elderly more susceptible to COVID-19. This deadly combination is a stark reminder, again, of doing our best to stay healthy.

Reich and colleagues show that even for the same "R," transmission rate, on average, infections can rise faster with a higher "gamma," the measure of how many "degrees" of contacts a person in the society has -- the super-spreaders.

According to researchers at Rocky Mountain Laboratories, some viral particles remain viable up to four hours on copper, twenty-four hours on cardboard, and seventy-two hours on plastic and stainless steel, though the number of viable particles begins to decrease within minutes.

Determining the necessary spacing for effective social distancing, such as for riders in a subway car, can affect the extent of disease transmission. The shaded circle (top) shows the number of people who could be directly infected by droplets from a sick person.

Reich and colleagues construct graphs of people in their various states of infection and the like among people, to simulate how COVID-19 spreads. Caption from the article: "Contact tracing. Some share of the neighbors of a node which tests positive are traced and tested themselves." Reich et al. 2020

Graphic source:

This graph shows how an epidemic might spread across a network over time. Blue dots are susceptible individuals, while red dots are infected people. Two dots are connected by a line if they are in contact with each other, and the more contacts a person has, the bigger their dot is on the network. Author provided

Infected people are red nodes, and susceptible people are blue. The large node in the middle of the diagram is a super-spreader, a person who connects with many others, and thus has more potential to spread the disease.
