BIOWAR BULLYING OF CUBA
It is somewhat naive to look for "smoking guns" when trying to
understand how biowarfare may have contributed to emerging
diseases- biowarfare is prized in large part precisely BECAUSE
it leaves no smoking gun.
However, what does become evident in time, amid many allegations
that are supported but unproven, are some clear and consistent
I previously described how a major dengue fever erupted in Cuba
at the exact time that gays in America began getting AIDS.
I described how courtroom testimony of alleged participants
indicated deliberate attempts to spread the disease.
It is not simply a case of one or two diseases or incidents, however.
The larger context is an ongoing series involving a great variety of
Starting in 1962, a CIA agent who helped direct worldwide sabotage
efforts revealed that "There was lots of sugar being sent out from
Cuba, and we were putting lots of contaminants in it." 
President Kennedy was furious that a precedent could be set for
chemical sabotage in the Cold War (New York Times, 4/28/66).
The same year, a Canadian agriculture technician working as an
adviser to Cuba was paid $5000 by "an American military
intelligence agent" to infect Cuban turkeys with Newcastle virus.
Subsequently, 8000 turkeys died. The Washington Post reported
that "the Cubans - and some Americans - believe the turkeys
died as a result of espionage." (3/21/77)
Newcastle disease virus (NDV) is a paramyoxovirus and causes
fatal respiratory infections in poultry. By 1985, at the Society
for General Microbiology in England, inventors were presenting
newly developed methods for cloning NDV genes with
recombinant DNA techniques. Other literature relating to
NDV shows development of methods for "Purification and
Isolation" (Scheid et al, Jour. of Virology, 1973), "Use of
Antibodies (Avery et al, Infections & Immun., 1979),
"Hybridization of Synthetic...", (Wallace et al, Nucleic Acids
In 1971, also according to participants, the CIA turned over to
Cuban exiles a virus which causes African swine fever.
Six weeks later, an outbreak of the disease in Cuba forced the
slaughter of 500,000 pigs. The outbreak, the first ever in the
Western Hemisphere, was termed by the United Nations
Food and Agricultural Organization as "the most alarming
event of the year." 
Cuba has a "CIA Museum" in Havana, dealing with numerous
biowarfare attacks, as well as many other types of high-tech
harassment. You can take a tour of this on the web, complete
with a photo gallery of many captured CIA gadgets, and
pictures of crop damage.
The current embargo against Cuba includes an inhumane
blocking of AIDS treatments- obviously, our country cares
little how many get infected or die of the disease, there.
Perhaps the same recklessness and lack of concern could
once have been directed against gays, as well.
