Vaccination against COVID-19 remains the most effective way to combat the pandemic. In the United States, COVID-19 cases and deaths have declined dramatically since their peak in early January 2021, thanks in part to increased vaccination coverage. [1] However, between June 19 and July 23, 2021, COVID-19 cases increased by approximately 300% nationally, followed by an increase in hospitalizations and deaths, driven by the highly transmissible variant B. 1. 617. 2 (Delta). * SARS-CoV-2. , the virus that causes COVID-19. Available knowledge implies that vaccines are legal in the U. S. Pfizer-BioNTech, Moderna and Janssen [Johnson]
The main way people become infected with SARS-CoV-2 is through exposure to respiratory fluids containing infectious viruses. § The risk of transmitting SARS-CoV-2 outdoors is low. [4,5] CDC recommends that the public health government prioritize indoor protection methods. No single strategy is sufficient to prevent transmission, and multiple interventions should be used simultaneously to slow the spread of the disease. [6] Proven and effective methods against SARS-CoV-2 transmission, beyond vaccination, come with consistent and correct mask use[7,8], maximizing ventilation by dilution[9,10] and air filtration[11]. and maintaining physical distancing and avoidance. Crowds. [12,13] Basic public fitness measures, such as staying home when sick, washing hands, and cleaning high-touch surfaces, also deserve to be encouraged.

What do we already know about this topic?
COVID-19 vaccines, legal in the U. S. , are effective against severe illness and death from SARS-CoV-2 infection; however, the existing policy in the U. S. UU. es irregular. The implementation of multilevel prevention reduces the transmission of SARS-CoV-2.
What does this add?
Given the spread of the highly transmissible Delta variant, local decision makers deserve to evaluate the following points to indicate the need for multipoint prevention methods in settings: SARS-CoV-2 network transmission point, fitness formula capacity, vaccination coverage. , ability to stumble early with the accumulation of COVID-19 cases and populations at risk of severe COVID-19 consequences.
What are the implications for public practice?
While scaling up COVID-19 vaccination policy remains the most effective way to combat the pandemic, in the short term more prevention methods will be needed at various levels to minimize preventable morbidity and mortality.
