He said that the Delta variant could rise in different areas, even though overall vaccination rates are increasing and new COVID-19 case numbers go down.Fauci stated that there is a "difference in willingness to get vaccinated." There are states with a lower level of vaccination than 35%. In these circumstances, it is possible to expect spikes in certain areas, certain cities, and certain counties.He said, "And in certain places, some states and some cities, where the level or virus dissemination is high but the vaccination level is low, that's where you will see the spikes."The variant has already been identified in all 50 US states. Health officials across the country continue to encourage Americans to get vaccinated against it.The Delta variant has impacted five states, namely Arkansas, Colorado and Nevada.Certain counties in some states are experiencing significantly higher coronavirus cases. The Delta variant is the reason for the rise in coronavirus cases, according to health officials.For example, Colorado is seeing an overall decrease in coronavirus cases. However, there are spikes in the Delta variant. According to The New York Times COVID-19 tracker, Mesa County has seen a 34% rise in positive coronavirus cases in the past two weeks.Fauci stated Sunday that the Delta variant is "more effective and efficient in transmitting from person to person." It is clear that the Delta variant appears to be more deadly in the sense that you can get more serious diseases, which can lead to hospitalization and sometimes even death.According to Johns Hopkins University's latest data, more than 605,000 Americans have died due to the coronavirus. JHU data show that 47% of US citizens are fully vaccinated against coronavirus.Fauci stated that he doesn't believe you will see any spikes in the Delta variants. "Because thankfully, we have a substantial portion of the population vaccinated. It's going be regional. This is the part that people will find confusing about our work. There will be two kinds of America, as I have said.
