An overview of the anthrax virus

It is not related to the virus mentioned below. Anthrax is a memory resident, multi-partite virus. It also writes a copy of itself on the last few sectors of the system's hard disk, overwriting any data present. When the system is booted from the hard disk, the virus becomes memory resident.

Review of Fall Anthrax Bioattacks under construction compiled by Wm. Robert Johnston last modified 28 September Summary: From mid-September to Novembera number of anthrax-laced letters were mailed to news media offices on the U.

A total of 22 individuals contracted either cutaneous anthrax 11 cases or inhalational anthrax 11 casesand 5 died all from inhalational anthrax. Anthrax cases included individuals at targeted locations 9 casespostal service employees 9 casesindividuals who handled cross-contaminated mail 2 casesand individuals with unpinpointed exposures 2 cases.

An additional case of cutaneous anthrax occurred in March due to laboratory exposure to collected samples. The anthrax employed in the letters was a common genetic strain and had been treated to maximize its tendency to aerosolize. The genetic strain as well as the method of weaponization suggest the perpetrator s had access to U.

The perpetrator or perpetrators remains unidentified, although the investigation came to focus on a domestic source. Anthrax is a bacterial disease caused by Bacillus anthracis. Three forms of exposure exist--cutaneous skin exposuregastrointestinal entering through the digestive systemand inhalation.

Naturally occurring anthrax is generally contracted from infected livestock. Most modern natural cases of anthrax are cutaneous. Inhalational anthrax has a higher case-fatality rate than the other two forms.

Given the relatively low LD and the persistence of anthrax in the environment in the form of inert spores, anthrax has been weaponized by several national bioweapons programs. Most nations ceased offensive bioweapons research in accordance with the Biological Weapons Convention treaty.

The United States ceased its programs inbut continued research for defensive purposes. The Soviet Union continued a large-scale biowarfare program. In April an accidental leak from a Soviet bioweapons production facility in the city of Sverdlovsk, Russia, resulted in an anthrax outbreak which caused at least 68 deaths some reports suggest about fatalities among to cases.

In Iraq admitted to research and production of weaponized anthrax. Aum Shinrikyo, a group which conducted terrorist attacks using sarin nerve gas in Tokyo inhad engaged in research and attempted use of anthrax but was apparently unsuccessful.

In the United States, anthrax is currently a rare disease. Prior tothe last case of inhalational anthrax in the United States was in He was apparently exposed prior to departing on vacation 26 Sept.

Anthrax was suspected the same day by hospital staff and confirmed by the CDC on 4 Oct. Stevens died the afternoon of 5 Oct. Unconfirmed reports suggest that the source was a letter received in late Sept. Two mailroom workers tested positive for exposure to anthrax.

One of these workers, E. Blanco, 73, was hospitalized and subsequently diagnosed with inhalational anthrax 15 Oct. Two hospitalized co-workers turned out to have pneumonia and recovered.

Traces of anthrax were found in a Boca Raton post office on 15 Oct. Two suspected terrorists in the 11 Sept. New York City, New York: The letter was postmarked 18 Sept. Initial suspicion erroneously focused on a letter postmarked 20 Sept.

Petersburg, FL, accompanied by a white powder. A police officer and two laboratory technicians who handled the letter were exposed to spores, it was announced 14 Oct.

Anthrax was at one point suspected to have been spread to the Manhattan office of Governor Pataki, but later tests discounted this. The 7-month old son of an ABC employee has tested positive for cutaneous anthrax, it was announced 15 Oct.

It is suspected but not established that the child was exposed in a visit to ABC offices on West 66th St. The child was hospitalized shortly thereafter. Fletcher, 27, a female staff member of CBS has developed cutaneous anthrax from an unknown source, presumed to be a letter, it was announced 18 Oct.In the 20th Century more people died from viral infections than from all the wars around the globe.

Anthrax is a deadly bacterial disease. Overview. Anthrax is a rare but serious illness caused by a spore-forming bacterium, Bacillus anthracis. Anthrax mainly affects livestock and wild game. Humans can become infected through direct or indirect contact with sick animals.

Jan 16,  · The anthrax vaccine, formerly known as Anthrax Vaccine Adsorbed (AVA), developed in , was offered to individuals felt to be at risk of exposure.

Only a minority of those who were offered the vaccine accepted the vaccine secondary to perceived threat of vaccination (Niu et al., ).

Anthrax is a serious infectious disease caused by gram-positive, rod-shaped bacteria known as Bacillus anthracis.

Although it is rare, people can get sick with anthrax if they come in contact with infected animals or contaminated animal products. A biosafety level is a set of biocontainment precautions required to isolate dangerous biological agents in an enclosed laboratory facility.

The levels of containment range from the lowest biosafety level 1 (BSL-1) to the highest at level 4 (BSL-4). In the United States, the Centers for Disease Control and Prevention (CDC) have specified these levels. In the European Union, the same biosafety.
