An American woman has been put in quarantine by police after they found that her skin was crawling with nearly invisible bloodsucking parasites from an infested bird's nest in her home.

The woman has been taken to a hospital quarantine unit.

Police say they were called to the Long Island home of 45-year-old Nina Bradica on Thursday night. They say she was infected with bird mites, a highly contagious condition she contracted from a nest inside a bathroom vent.

Tiny bird mites usually can't be seen without magnification. Symptoms of human infestation include pinprick bites, red bumps, intense itching and a crawling sensation on the skin.

Firefighters and hazardous-materials officers put the woman in a protective suit and took her to the hospital for treatment.
