"We're better off now than we were a couple of months ago, that's for sure," Fauci told CNN's Chris Cuomo Monday night. But the country is still not where it needs to be, he said.
In the battle against the virus, experts have continually stressed how testing is critical. When done right, it can help health officials identify infections quickly and place those individuals in isolation before more people become infected. It can also give local leaders an idea of the level of infection within a community.
"We need to flood the system with testing," Fauci said.
The US has conducted more than 107 million tests since the pandemic began. More than 210,000 Americans have died and there have been more than 7.4 million recorded infections -- but the number of true infections is likely far greater than that, the US Centers for Disease Control and Prevention has said. And that's likely because of the lack of testing in the first months of the pandemic, experts say.
Several states hit record-highs
Overall cases in the US are on the rise. The country reported more than 50,000 daily cases on Friday and Saturday. The last time the US saw more than 50,000 cases back to back was mid-August.
According to data from Johns Hopkins University, at least 22 states are reporting more new cases than the previous week, with many across the Midwest and now increasingly in the Northeast.
Only four states are reporting a decline -- Hawaii, Kansas, Missouri and South Carolina. The rest are holding steady.
Several states have also reported record-highs in recent days.
In the past days, several states reported record high numbers.
Alaska, Indiana, Kentucky and Montana reported their highest 7-day averages for new daily cases over the weekend, according to data from Johns Hopkins University.
Alaska is reporting more than 40% more new cases than the previous week. In Kentucky, where Gov. Andy Beshear last week raised alarm about "escalating" cases and urged residents to be on guard, he announced Monday the state will be stepping up mask enforcement.
"We need to make sure that everybody out there is getting back to the place where, in your business, you cannot check somebody out if they are not wearing a mask, it shouldn't matter who they are," he said Monday.
In Wisconsin, new cases are averaging at about 2,400 daily -- the third highest in the country behind Texas and California. That's up 15% from what the state was averaging in the previous week.
What happens when measures are relaxed
A new study that analyzed Covid-19 data from all 50 states and DC found lockdowns helped slow transmission of Covid-19, but loosened restrictions let the virus spread again.
"Essentially the moment those restrictions were released, those trends reversed," Dr. Mark Siedner, an investigator in the Division of Infectious Diseases at Massachusetts General Hospital, who led the research team, said in a statement.
Experts have said that a second lockdown isn't necessary to get the virus under control: strong safety measures like universal face masks, social dista
