This sounds icky.

A vicious skin infection resistant to all but the most powerful antibiotics has jumped out of New York City hospitals and onto the streets.

The “superbug,” as health officials refer to it, can cause anything from reddening of the skin, to abscesses, tissue loss, amputation or even death in severe cases, doctors said.

For decades confined to hospitals, where it preyed on patients and built up immunity to antibiotics, the bug - known officially as Methicillin Resistant Staphylococcus Aureus or MRSA - has also grown in strength.

“Usually with infections you need a break in the skin to pass it,” said Dr. Howard Grossman, who has a private practice in Chelsea.

“Not with this. It gets through unbroken skin with casual contact.”

Nasty…
