"There are not, there are definitely no additional cases at this time. We have one case, a single isolated case of anthrax. And, you know, every hour that goes by that we don't have another case is good news for citizens of Palm Beach County as well as the state of Florida."
A 63-year-old British-born Florida man died of the inhaled form of anthrax on Friday in the first such death in the United States in 25 years.
Health officials said there is no evidence he was the victim of a terrorist attack, but the F-B-I and C-D-C (Centres for Disease Control) are investigating.
Dr. Jean Malecki said Bob Stevens, a photo editor at the supermarket tabloid The Sun, failed to respond to the antibiotics he had been given and died at 4 p.m. local time (2000 GMT)
Dr. Larry Bush, an infectious disease specialist, said Stevens suffered kidney failure and then cardiac arrest and could not be resuscitated.
Dr. Steve Wiersma, a state epidemiologist, said officials still believe Stevens contracted anthrax naturally, but as a precaution the FBI is assisting in the investigation into where he contracted the disease.
Federal and state health investigators have emphasised that the disease is not contagious and that no other cases have been reported.
But they are trying to reconstruct Stevens' movements over the past two months and track down the source of the disease.
The case has attracted heightened attention because anthrax has been developed by some countries as a possible biological weapon.
The terrorist attacks on the U-S last month have put many people on edge about the threat.
The Stevens house is located near the Palm Beach airport where at least one of the alleged terrorists took flying lessons and crop dusting lessons
But anthrax can also be contracted naturally, often from farm animals or soil.
F-B-I, C-D-C and state investigators sealed off Stevens' house in Lantana and searched it for about two hours on Friday.
They were also searching his workplace.
Only 18 inhalation cases in the United States were documented in the 20th century, the most recent in 1976 in California.
The last anthrax case in Florida was in 1974, according to the state health department.
