(CNN)There are nearly 40,000 people in ICE custody across the United States. And there's a big question looming as the novel coronavirus spreads.
What will happen if there's an outbreak inside one of Immigration and Customs Enforcement's detention facilities, which have long faced criticism for how they handle even routine medical care?
ICE says there aren't any confirmed coronavirus cases at its detention facilities -- and that protecting the health and safety of those in its custody is one of the agency's top priorities.
The White House is asking Congress to boost ICE's budget so the agency can increase its quarantine capacity. Immigrant advocacy groups are pushing for ICE to release detainees now, before it's too late. And immigrants held in at least one family detention facility say they don't feel safe.
As this complex and fast-moving situation evolves, here are some of the key developments to watch:
ICE has put social visits on hold
As part of its efforts to stop coronavirus from spreading, the agency recently said it was temporarily suspending social visitation at ICE facilities "as a precautionary measure" -- meaning family members, friends and advocates who used to be able to visit detained loved ones in person can't anymore, at least for now.
That means one of the few windows in to a vast detention system that's often hidden from public view is closed. And some detainees are scrambling to come up with funds to make calls so they can stay in touch with their families. Amilcar Valencia, executive director of El Refugio, which hosts regular volunteer group visits at the Stewart Detention Center in South Georgia, says his organization is now working to raise money to help detainees call their loved ones. But something important is lost, he says, when visitors can't meet with detainees.
"Just being present there sends a message that people are not forgotten. They are not alone. They can see that there's people from the outside there, and it brings a level of accountability for staff and for ICE as well," he says. "Now that's not happening. We don't have that contact with people, and we don't have that direct connection, and we might lose that direct information that we get from them."
The White House wants to boost ICE's budget to expand quarantine capabilities and fund more deportation flights
The White House is asking Congress to give ICE $249 million more as part of its emergency coronavirus funding request. This is how the White House says the money would be spent, according to the funding request that was sent to lawmakers Tuesday night:
• Converting four facilities into dedicated quarantine facilities on the southern border and provide enhanced sanitation and janitorial services.
• Increasing the number of migrants in its Alternatives to Detention Program, which allows the agency to keep tabs on immigrants released from custody with things like ankle monitors and regular check-ins. "This would allow ICE to minimize the risk of further exposure to detainees and prevent transmission within the detention system," the budget request says.
• Funding for more charter aircraft for the division known as ICE Air, which coordinates deportation flights. "With fewer commercial flight options, ICE charter aircraft are needed to continue repatriating aliens ordered removed and reduce the need for additional beds," the request says.
• Providing personal protection equipment for ICE staff
Advocacy groups are calling for ICE to release detainees
While there aren't any confirmed cases of the novel coronavirus in ICE detention, we've heard about quarantines and outbreaks of other viruses in these facilities many times before.
And for years advocacy groups have warned that conditions in ICE custody are detrimental to detainees' health -- allegations that ICE has repeatedly denied.
Now a number of human rights organizations and immigrant advocacy groups are calling for ICE to release detainees. Some are asking for the agency to release detainees with underlying medical conditions. Others, like the Detention Watch Network, are pushing even further, saying all detainees should be let out.
In a federal lawsuit filed this week, the American Civil Liberties Union asked a judge to order ICE to release nine detainees from the Tacoma Northwest Detention Center near Seattle.
