Homeland security expert Juliette Kayyem spoke with Boston Public Radio on Wednesday about the longevity of the coronavirus pandemic.

"We're at the beginning of the response phase of the crisis," she said. "It's going to get harder before it gets easier."

Self-isolation is the effective path forward, Kayyem said.

"This is going to be a 50 state response, and our obligation is a that for couple weeks, it's going to be like this for us all to social distance," she said. "The good news is that there is complete convergence among the medical, homeland security and economic experts that there's only one path forward, which is that we're isolating ourselves."

Kayyem is an analyst for CNN, former assistant secretary at the Department of Homeland Security and faculty chair of the homeland security program at Harvard University’s Kennedy School of Government.
