Dr. Anthony Fauci was at a loss to explain why coronavirus cases and deaths continue to fall in Texas despite the state reopening.

During an interview on MSNBC Tuesday morning, Fauci was asked to comment on the positive numbers in Texas.

The MSNBC host said, "Texas effectively opened up, dropped all those restrictions and said, 'It's back to life.' And if you go to Texas, as you know, it looks like 2019. The restaurants and the bars are full and open. The ballparks are full, and yet, we've seen cases and hospitalizations since then continue to tick downward."

Fauci, senior advisor to the White House, was pressed by MSNBC to explain why the cases aren't spiking.

"Yeah, you know, it can be confusing because you may see a lag and a delay, because often you have to wait a few weeks before you see the effect of what you're doing right now," said Fauci. "There are a lot of things that go into that. When you say they had a lot of activity on the outside like ball games. I'm not really quite sure... I hope they continue to tick down, if they do that would be great. But there's always the concern that when you pull back on methods, particularly things like indoor dining, and bars that are crowded, you can see a delay, and then all of a sudden cases tick back up."

Fauci soldiered on, despite being wrong about the coronavirus in the past.

"We've been fooled before by situations where people begin to open up -- nothing happens, and then all of a sudden several weeks later, things start exploding on you."

It has been more than a month since Texas reopened. And states such as Florida and Georgia have been wide open since last summer.
