Any policy changes that hot spot states like Texas and Florida decide to implement now likely won't affect the spread of the coronavirus for weeks to come, former Food and Drug Administration Commissioner Dr. Scott Gottlieb told CNBC on Thursday.
Due to the lag in how long it takes once someone is infected to develop symptoms, get tested and receive results, a confirmed case today could reflect an infection that occurred up to three weeks ago, Gottlieb said. He added that even if states currently struggling with outbreaks implemented more stringent measures, cases would continue to rise for some time.
"I think it's going to be difficult now to get this under control," Gottlieb said on "Squawk Box." "Whatever these states do right now is really going to help them in about two weeks, maybe a little bit longer than that. Whatever policy decisions they made a week or two ago, that's what we're seeing flow through right now."
California, Florida and Texas all reported record high single-day jumps in new cases on Wednesday. California reported 7,149 new cases on Wednesday, bringing the state's total to 190,222, according to the state's health department. Florida reported 5,508 new cases Wednesday, shattering the previous record single-day increase and bringing the state's total to 109,014, according to the state's health department. And Texas reported 5,551 new cases Wednesday, bringing its total to 125,921 confirmed cases.
In New York City, which had been the epicenter of the U.S. outbreak, officials issued a stay-at-home order on March 20. But daily new cases did not peak until April 6, when the city reported 6,376 new cases, according to the city's health department.
"So we know that there's a delay between the implementation of policy and actually affecting the scope of the epidemic," Gottlieb said. "The next week or two is largely baked in terms of what impact you can have on it from policy, so they need to start thinking a little bit longer term, where they think they're going to be in two weeks based on the current trajectory and start implementing policy to try to affect that."
Governors in Florida and Texas, as well as some other states that have reported signs of an expanding epidemic, have expressed doubt about ordering businesses to close again or placing more restrictions on individuals. Neither Texas nor Florida has implemented statewide mask mandates, but both recently allowed local and city officials to issue such orders for their residents.
"They're not going to shut down their economies. It's very clear," Gottlieb said. "They're going to weather this, but they need to look at some selected shut downs of congregate settings like, perhaps, bars."
While national attention remains on the states reporting the largest spikes in new cases, Gottlieb said outbreaks now appear to be worsening in several other states as well, including Georgia, Alabama and Arkansas. Officials in those states might begin to implement restrictions again if their hospital systems begin to face pressure, Gottlieb said.
"This isn't just confined to a handful of states anymore," he said. "When the hospitals start to get pressed, they're going to press policymakers to try to take steps to mitigate the burden on the health-care systems."
While governors in Florida and Texas have said there is plenty of statewide hospital capacity, some particularly hard-hit parts of those states are beginning to approach capacity. In Houston, for example, Texas Children's Hospital said this week it will begin to admit adult patients to alleviate burdened hospitals.
Testing continues to increase in most states, Gottlieb noted, which helps health officials detect new cases and potentially intervene early by asking infected people to remain home while they recover. However, he added that in some states, including Florida, testing has actually decreased in recent weeks.
"If you don't want to shut down the economy, you've got to decide what you're for and if you're going to be against universal masking, and against testing, against tracing and you don't want to shut down the economy, you're just going to have to tolerate then a very large epidemic," Gottlieb said.
