It is imperative for public health, economic, and social functioning that US leaders establish and communicate specific goals for COVID-19 management, benchmarks for the imposition or relaxation of public health restrictions, investments and reforms needed to prepare for future SARS-CoV-2 variants and other novel viruses, and clear strategies to accomplish all of this.
The goal for the “new normal” with COVID-19 does not include eradication or elimination, eg, the “zero COVID” strategy. Neither COVID-19 vaccination nor infection appear to confer lifelong immunity. Current vaccines do not offer sterilizing immunity against SARS-CoV-2 infection. Infectious diseases cannot be eradicated when there is limited long-term immunity following infection or vaccination or nonhuman reservoirs of infection. The majority of SARS-CoV-2 infections are asymptomatic or mildly symptomatic, and the SARS-CoV-2 incubation period is short, preventing the use of targeted strategies like “ring vaccination.” Even “fully” vaccinated individuals are at risk for breakthrough SARS-CoV-2 infection. Consequently, a “new normal with COVID” in January 2022 is not living without COVID-19.
The “new normal” requires recognizing that SARS-CoV-2 is but one of several circulating respiratory viruses that include influenza, respiratory syncytial virus (RSV), and more. COVID-19 must now be considered among the risks posed by all respiratory viral illnesses combined. Many of the measures to reduce transmission of SARS-CoV-2 (eg, ventilation) will also reduce transmission of other respiratory viruses. Thus, policy makers should retire previous public health categorizations, including deaths from pneumonia and influenza or pneumonia, influenza, and COVID-19, and focus on a new category: the aggregate risk of all respiratory virus infections.
What should be the peak risk level for cumulative viral respiratory illnesses for a “normal” week? Even though seasonal influenza, RSV, and other respiratory viruses circulating before SARS-CoV-2 were harmful, the US has not considered them a sufficient threat to impose emergency measures in over a century. People have lived normally with the threats of these viruses, even though more could have been done to reduce their risks.
