The claim that the United States military created AIDS was the centerpiece of a Soviet disinformation campaign in the 1980s, known to historians as Operation INFEKTION (sometimes "Operation Denver"). Planted in an obscure Indian newspaper in 1983 and amplified by Soviet and East German intelligence services, it spread to dozens of countries. Russian officials later acknowledged the KGB's role, yet versions of the claim remain widely believed decades later.

The claim

In its fullest form, the claim holds that American scientists engineered HIV, the virus that causes AIDS, at the US Army's biological research center at Fort Detrick, Maryland, and that the disease either escaped or was deliberately tested on prisoners, gay men or populations in Africa. Some versions say the virus was designed to target Black people.

Origin

On 16 July 1983, the Patriot, a small pro-Soviet daily newspaper in New Delhi, published an anonymous letter headlined "AIDS may invade India: mystery disease caused by US experiments." The letter claimed to come from "a well-known American scientist and anthropologist" and said the Pentagon had created AIDS through genetic engineering. No such scientist was ever identified. The Patriot had been founded with Soviet support, and the letter fits a pattern intelligence historians later documented: placing a story in a friendly foreign outlet so that it could later be cited as independent "foreign reporting."

The story lay dormant until October 1985, when the Soviet weekly Literaturnaya Gazeta revived it, citing the Patriot as its source. From there it entered the Soviet press system and the networks of sympathetic publications around the world.

The scientific veneer

In 1986, the campaign gained an apparently scientific foundation. Jakob Segal, a retired East German biophysicist, and his wife Lilli Segal produced a report arguing that HIV had been created at Fort Detrick by combining two existing viruses, visna (a sheep virus) and HTLV-1, and that it had been tested on prisoners who then spread it after release. The report was distributed at a conference in Zimbabwe and widely cited.

Virologists rejected the Segal hypothesis. The genetic makeup of HIV is not consistent with a combination of those viruses, and the genetic engineering techniques the theory required did not exist in the 1970s, when the virus would have to have been made. Historians later found evidence that the East German Stasi's foreign disinformation unit helped promote Segal's work, though Segal himself may have believed his theory.

How it spread

The campaign succeeded because it exploited real grievances and real history. The United States had in fact run biological weapons programs before 1969, and the Tuskegee syphilis study, in which US Public Health Service researchers withheld treatment from Black men for four decades, had been exposed in 1972. Against that background, a claim of government medical abuse did not sound absurd to many listeners.

By 1987, the story had appeared in the media of dozens of countries across Africa, Asia, Latin America and Europe, according to US government tracking. It was repeated on television, in pamphlets and in newspapers, often citing one another in a loop that made the claim look widely confirmed.

How the record changed

In 1987, under diplomatic pressure from the United States and in the climate of Mikhail Gorbachev's reforms, Soviet officials began distancing themselves from the claim, and some Soviet scientists publicly rejected it. In 1992, Yevgeny Primakov, then head of Russia's foreign intelligence service, acknowledged that the KGB had been involved in spreading AIDS disinformation. Former Stasi officers and archival research after German reunification added further detail.

What the evidence shows

The origin of HIV is well established. HIV-1, the main form of the virus, descends from a simian immunodeficiency virus that crossed from chimpanzees to humans in west-central Africa, most likely through contact with blood during the hunting and butchering of bushmeat. Genetic studies of archived virus samples place the origin of the pandemic strain in the early twentieth century, decades before genetic engineering was possible, with Kinshasa in today's Democratic Republic of the Congo identified as an early center of spread. The oldest confirmed human HIV sample dates from 1959.

There is no evidence that HIV was created in any laboratory, American or otherwise.

Why it persisted

Long after the campaign ended, the claim endured, especially in communities with good reason to distrust medical authorities. A study published in 2005 found that nearly half of African American respondents believed HIV was man-made, and about a quarter believed it had been produced in a government laboratory. Researchers found that such beliefs were associated with more negative attitudes toward condom use and HIV prevention, showing how a disinformation campaign can have real public-health consequences long after it is exposed. In South Africa, related beliefs contributed to official skepticism about HIV science in the early 2000s.

The case is also a reminder that effective disinformation often borrows the credibility of genuine wrongdoing. Real abuses, such as Tuskegee, made a false story believable.

Lessons for readers

Ask where a story first appeared. A claim that began as an anonymous letter in a single small outlet, then was repeated by others citing that outlet, has only one source, however many times it is reprinted.
Beware of borrowed authority, such as an unnamed "well-known scientist."
Distrust grounded in real history deserves respect, but it does not make every claim of abuse true.
