New modeling shows continued surge in COVID-19 cases, Nov. 16

The Oregon Health Authority released its latest modeling indicating a steep increase in the spread of COVID-19 dating back to early November. According to the model, the effective reproduction rate – the expected number of secondary cases that a single case generates – was estimated to be between 1.25 and 1.69, with an estimate of 1.47.  The current level of transmission could result in “exponential” growth, resulting in approximately 1,500 new daily cases over the next two weeks. The model does have limitations, including that it is based on Oregon data only through November 6. According to the model, if Oregonians collectively wear masks, keep physical distance, restrict social gatherings and maintain good hand hygiene to slow the spread of the virus, new cases would remain historically high for a short time before decreasing. Social gatherings continue to fuel transmission. OHA is urging Oregonians to rethink their social activities over the next few weeks and to reconsider their holiday plans. Here are some actions people can take to keep COVID-19 from spreading through social gatherings: Minimize close contact with others. Work from home to the extent possible. Limit social gatherings. Reconsider holiday plans to keep them to a small group. Reduce social interactions with people outside of your household.
