The peak of illnesses occurs at the end of the acceleration phase, which is followed by a deceleration phase, during which there is a decrease in illnesses. Different countries can be in different phases of the pandemic at any point in time and different parts of the same country can also be in different phases of a pandemic.” 3 The risk of viruses depends on its characteristics, including how fast it can spread between people, the severity, and measure available to control the impact of the virus. In the absence of vaccine or treatment medications, nonpharmaceutical interventions become the most important strategy for response. The risk from COVID- 19 to Americans can be broken down into risk of exposure vs risk of serious illness. Currently, the immediate risk of being exposed to this virus is still low for most Americans until the outbreak expands. Cases of coronavirus and community spread are being reported in a growing number of states. Most people in places where ongoing community spread of the virus are at an elevated risk of exposure, with the level of risk dependent on the location.
