"At NBC, there's one other person who apparently handled the letter that was sent to NBC, who is now confirmed to have developed cutaneous anthrax, that person has been treated for quite some time with antibiotics, including Cipro, and is making from all intents - from everything people can tell, a full and complete recovery. There is another person also at the New York Post. That's described as probably anthrax."

"In addition late last night we learned the environmental test in the freight elevator in the south-west quadrant of the senate Hart office building tested positive. Based on this finding the attending physician now recommends that anyone who rode in that freight elevator on October 11, the probable date the letter was delivered to my office or later be treated with a 60 day course of antibiotics."

The US Environmental Protection Agency has released the first pictures of anthrax decontamination work inside Florida's American Media building.
It was the first office hit in the recent wave of anthrax attacks.
Three Americans have died from anthrax mail attacks and there have been 13 cases of confirmed anthrax in the past three weeks.
At the American Media building in Boca Raton, a cleanup crew collected additional environmental samples to try to determine if there was any more anthrax present.
The crew found no spores in the first-floor air ducts, indicating the building contamination may be limited because the anthrax didn't spread through the ventilation system, the Environmental Protection Agency said.
The job is the first large-scale bio-cleanup for the EPA, which typically responds to oil and chemical spills.
Postal workers who processed mail for American Media are being given the option of taking antibiotics to ease concerns about anthrax.
A tiny amount of spores was found at four post offices, indicating an anthrax-tainted letter passed through the facilities before contaminating the tabloid publisher's headquarters, killing a photo editor.
The anthrax also infected 73-year-old mail room worker Ernesto Blanco, who was recovering at his North Miami home after being released from the hospital Tuesday.
The FBI has said anthrax likely entered the American Media building in a letter that was thrown away and destroyed.
In New York, four people - one linked to NBC, the New York Post, CBS and ABC each - have confirmed cases of cutaneous anthrax, which is far less dangerous than the inhaled form that has been found in cases elsewhere.
City health officials announced Thursday that a second case at NBC has been reclassified from possible cutaneous anthrax to "suspicious or probable."
The victim's name was not made public but NBC said she was a desk assistant who handled a letter sent to news anchor Tom Brokaw.
The letter said, among other things, "Take penicillin now" and "Death to America."
A biopsy had come back negative for anthrax, apparently because the woman was already being treated with antibiotics, but a blood test and her proximity to the letter prompted the reclassification by the Centers for Disease Control and Prevention.
In Washington a U.S. State Department mail handler has become the latest victim of an anthrax attack.
But as the worker lay ill, American lawmakers were permitted to return to several of office buildings on Capitol Hill.
U.S. Senate Majority Leader Tom Daschle said a wing in the Senate office building where anthrax was discovered last week would be sealed off indefinitely.
Trace amounts of anthrax were found in two more areas of the Senate office building where a letter containing the bacterium was opened, Daschle said Thursday.
The discoveries brought to three the number of places in the Hart building where anthrax has been found outside the office of Senate Majority Leader Tom Daschle.
The letter was opened in Daschle's fifth- and sixth-floor suite on October 15, leading to the testing of more than 6,000 people, the shutdown of all of Congress' office buildings for inspections and early adjournment last week by the House and Senate.
Officials played down the new anthrax sites, detected as investigators continued scouring the nine-story building.
The two new sites where anthrax was found were a stairway between the building's eighth and ninth floors, and a ninth floor ventilation filter.
Capitol Police said the day the letter was opened, Daschle's staff was brought up that staircase to a conference room, where they were checked by doctors.
The Hart building has been closed to lawmakers, aides and the public since October 17, the day all of Congress' office buildings were closed as a precaution.
Washington DC mayor, Anthony Williams, said a 59-year-old employee at the State Department's mail facility in suburban Virginia was hospitalized Thursday with inhalation anthrax.
A second man who works at the same mail facility as the infected worker has flu-like symptoms and is being tested at a hospital, according to officials.
Mail to federal agencies passes through the Brentwood facility, and the latest diagnosis added to the mounting evidence that investigators have not yet found all the anthrax-tainted mail in the area's postal system.
The State Department announced it would test employees at all of its mail annexed and its main facility several blocks from the White House.
In all 250 to 300 people are being tested for anthrax exposure, and about 80 people who work at the Sterling facility are receiving the antibiotic Cipro, according to the State Department.
Washington health officials say everyone who receives mail in bulk from the Brentwood facility needs to be receiving treatment for possible anthrax exposure.
