FYI:

The report is in that the man contracted Anthrax and lives in South Florida (Lantana). He had just returned form NC but I have not seen any print media reports yet. I have just returned from NC also and live in North Central Florida. The infected person is not expected to survive.

A few weeks ago I posted the following report from U of Cal Press (99): It seems appropriate to post this information again. There is also a message board forum here for Anthrax -> http://pnews.org/boards/anthrax/

The Investigation of a Deadly Outbreak

by Jeanne Guillemin

University of California Press, 1999

reviewed by Donald A. Henderson, MD, MPH

On April 2, 1979, a small cloud of anthrax spores was accidentally

released from a bioweapons production facility in Sverdlovsk, a Soviet

city in the Ural Mountains. It slowly drifted southeast over a portion

of the city's southern suburbs - invisible, unrecognized. Two days

later the first victims fell ill. Over the following six weeks, some

100 developed the disease and at least 70 died as a result of

infection acquired as much as three miles downwind from the release

point of the spores. This was the first and only known epidemic of

inhalation anthrax. Calculations suggest that the quantity of spores

released may have weighed less than one gram.

Anthrax is one of the most deadly of the biological weapons and the

agent most universally favored by those desiring to produce such

weapons. It is, in nature, a disease primarily of grazing animals who

acquire infection from contaminated soil. Natural infections in man

result from contact with animals or animal products and usually cause

an ulcer of the skin that is readily treated with antibiotics. There

are occasional small outbreaks of gastrointestinal disease when

undercooked, contaminated meat is consumed. However, inhalation

anthrax is an exceedingly rare but grave form of the disease that

kills upwards of 80% of its victims. From the onset of infection to

death is usually no more than 2 to 4 days. Antibiotics are of little

benefit in treatment unless administered very soon after the first

symptoms occur.

In her book, Anthrax, Jeanne Guillemin provides the only detailed

account of the appalling Sverdlovsk epidemic, an event which could be

repeated on a far larger scale were anthrax spores in an aerosol form

to be disseminated today by a terrorist. The book is structured around

the evolving investigation of the event led by Harvard biologist,

Mathew Meselson, assisted by the author and several Russian and

American scientists. The format is reminiscent of Berton Roueche's New

Yorker tales of epidemic sleuthing.

From the time of occurrence of the epidemic in 1979, Russian

scientists had attributed its cause to the consumption of contaminated

meat. However, rumors provided by emigres, suggested otherwise to US

intelligence analysts. In the interest of defusing suspicions about

Russian biological weapons developments, Meselson had repeatedly

pressed Russian officials and scientists for a full and open

investigation of the incident. Finally, in June 1992, permission was

granted for an American team to visit Sverdlovsk. Russian Ministry of

Health officials persisted in their assertion that the cause was

contaminated meat and provided little essential data. The challenge to

the team was that of investigating an epidemic more than a decade old,

one in which the clinical records had been confiscated by the KGB and

in which most victims had died of the disease.

At the outset, a critical breakthrough occurred with the discovery of

two pathologists who had performed numerous autopsies, 42 of which

they considered to be classical inhalation anthrax. Fortunately, the

specimens had been overlooked by KGB officials seeking to confiscate

all relevant data. An American pathologist on the team was able to

confirm them as being typical of inhalation anthrax. Thereafter, the

story unfolds as the author, assisted by Russian counterparts,

interviewed relatives of many of the survivors and gradually

assembles, piece by piece, considerable important information about

the epidemic.

Perhaps the most important finding was the discovery that the

incubation period for inhalation anthrax was NOT 2 to 6 days as

experimental animal studies had shown and as standard textbooks

proclaimed. Rather, it was 2 TO AT LEAST 45 days. The implication of

this finding is that after discovery of an epidemic, there would be

sufficient time to administer life-saving antibiotic prophylaxis to

prevent disease in as many as 75% of the potential victims.

Scientists and policy makers alike will be disappointed that the

author did not devote more time and effort to the analysis and

elucidation of the trove of epidemiological information that

apparently was collected. And what might have been a riveting

epidemiological detective story drifts too often into a rambling

travelogue with extended irrelevant digressions.

The book should be required reading for anyone seriously concerned

about biological terrorism. It is difficult to commend it to others

with a more general interest in epidemiology or cultural anthropology.
