Fatality Rate (0-1)

Fatality Rate is the proportion of infected people that ultimately die from a disease. Given that COVID-19 is relatively new, the case fatality rate is not accurate, and the reported rates are likely too high. This is because COVID-19 is not easy to identify or diagnose, and only those that are very sick are being identified as COVID-19 positive for the most part. This makes the calculated number of infections lower than it actually is, and in turn is inflating the death rate. There are other factors that affect the case fatality rate, such as the age of a population and the strength of health systems. NPR Article

Test and Trace: Test Symptomatic Rate (0-1)

The Test Symptomatic Rate defines the percent of people in our simulation that are tested when they become symptomatic, and subsequently contact traced if they are infected. According to Forbes, more than 260 million of the nearly 330 citizens in the United states have an Android or iPhone smartphone. This means that in the United States, if all of these smartphone users downloaded the contact tracing app being developed by Apple and Google, nearly 80% of citizens would be participating in this advanced Bluetooth-based contact tracing platform. This type of participation in contact tracing could increase the test symptomatic rate by helping to locate people that have been exposed to the virus.

Symptomatic Rate (0-1)

Symptomatic Rate refers to the probability that an infected person either shows visible symptoms as opposed to being an "asymptomatic carrier". CDC director, Dr. Redfield, estimates, as of April 2020, that 25% of people with COVID-19 may be asymptomatic. The director of the National Institute of Allergy and Infectious Diseases director, Dr. Fauci, estimates that 25-50% of people with COVID-19 may be asymptomatic. However, Medical News Today reported that it is possible that only 1-3% of people with COVID-19 are "asymptomatic carriers."

Symptom Start Time (1+)

Symptom Start Time is how long after contracting an infection the person starts having visible symptoms.Medical News Today reported on March 17, 2020 that according to a recent study, symptoms start appearing after an incubation period 2-14 days. The incubation period is the time separating transmission and the display of symptoms.

Test Number of Contacts (0-25)

The Test Number of Contacts parameter defines the number of recent contacts that will be tested as a result of contact tracing after a ball becomes infected. Each ball in our simulation keeps a record of its last 25 contacts so that if it becomes infected, its recent contacts can be tested through contact tracing.
