Paramedics and members of the National Guard will be making house calls this weekend. It's part of a city program to make sure those hard hit by Sandy are getting medical help if they need it.

"The sort of medical problems we think we might see would be people who are out of medication, people who are cold and maybe have hypothermia," said Health Commissioner Thomas Farley. "If people have had difficulty getting food or water they could certainly provide that." He added that people can also be transported to medical facilities, if needed.

City officials say the checks will continue from 8 a.m. to 8 p.m., at least through Monday.

"Power will be restored each day, so the number of buildings we need to go to will shrink over time," Farley said. "So we really don't know how long this operation will last, but we'll be here as long as we can."

Farley said three people did receive medical treatment, but no serious health issues were found on Friday.
