BOSTON (CBS) – The MBTA will start disinfecting its entire system more frequently and intensely because of the coronavirus threat.

At a news conference with Governor Charlie Baker at the State House Wednesday, MBTA General Manager Steve Poftak said the T will be cleaning everything several times a day to help reduce the risk of spreading the virus.

“Today, we’re going to put a protocol in place for each one of our stations, all the contact areas where people are touching, for instance, guard rails, hand rails, fare equipment will be cleaned every four hours,” Poftak said.

“Subject to getting enough disinfectant in place, we are going to move to a protocol where we will be disinfecting every vehicle, every day. Right now we have enough equipment on hand to be doing that on the commuter rail. We expect by the end of this week to be able to do it across the system – buses, subway cars and paratransit vehicles.”

Baker said the coronavirus risk to the public in Massachusetts remains low. There is one confirmed case in the state and and one presumed positive case.
