Pin prick attack

Pin prick attack is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Pin prick attack rather than just read about it. In short: A pin prick attack is an assault on another person with a needle or syringe tainted with the blood of somebody carrying a blood-borne disease, such as HIV. Although there have been numerous cases of people being attacked with needles and syringes, the idea that people infected with AIDS have deliberately attempted to infect others in this manner is generally considered an urban legend.

Key takeaways

  • Pin prick attack belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Pin prick attack to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Pin prick attack from memory before moving on to harder problems.

Reference excerpt

A pin prick attack is an assault on another person with a needle or syringe tainted with the blood of somebody carrying a blood-borne disease, such as HIV. Although there have been numerous cases of people being attacked with needles and syringes, the idea that people infected with AIDS have deliberately attempted to infect others in this manner is generally considered an urban legend. Real cases of infection of HIV in this manner were typically taken from infected victims rather than from infected attackers.

Origins Although tales of so-called "needle men" or white slavers, who supposedly injected unsuspecting young girls with morphine before carrying them away into a life of prostitution, had been around since the 1930s, the specific case of infection with blood borne diseases might have had its roots in a 1989 incident where ten teenage girls were arrested and later charged with stabbing numerous women with pins on the Upper West Side of Manhattan in New York City.

As an email/Internet scare story The rise of the Internet in the 1990s led to the rise of numerous urban legends concerning the pin prick attack, which could be quickly spread via email and discussion forums and which soon assumed a standardized form. The email would take the form of a warning to others that a young person had been visiting a cinema or a night club when the person felt a slight prick on his or her arm. Not taking any notice, the person would carry on with his or her leisure activity, and it was only later that the person would find stuck to his or her clothes or in his or her pocket a badge or sticker carrying the slogan "welcome to the AIDS club", followed a few months later with a positive HIV test. These rumors bear similarities to the so-called AIDS Mary legends of the 1980s, whereby a man would enjoy a one-night stand with a stranger at his house and awaken the next morning to find the stranger gone and the words "Welcome to the AIDS Club" written in red lipstick on his bathroom mirror. However, the American Centers for Disease Control has stressed on numerous occasions that it has yet to confirm a single case of HIV as being transmitted in this fashion and has dismissed such emails as a hoax. The hoax was re-emerged in 2017 through social media, claiming that members of Islamic State (often mistranslated to "The Islamic Cult") are supposedly posing as doctors, moving from house to house in order to conduct "insulin checkup" while injecting them with HIV. The re-emergence of the hoax was documented in places like India, Israel, The Philippines and the U.S.

Documented examples In 1933, a pin prick attack led to the death of Indian man Amarendra Pandey from plague. A pin prick attack leading to the deliberate transmission of HIV occurred at the Long Bay Jail in Sydney on July 22, 1990, when prison officer Geoffrey Pearce was attacked by HIV-infected prisoner Graham Farlow, who stabbed him with a syringe full of his own infected blood. Despite immediate medical attention and the "one in 200" chance of being infected, Pearce tested positive for the disease a few months later, and died of an AIDS related illness in 1997 at age 28. In 1992, Brryan Jackson was injected with a syringe of HIV-infected blood by his father. Jackson was diagnosed with AIDS that same year. In 1998, Richard J. Schmidt, a physician in Lafayette, Louisiana, was convicted of attempted murder after injecting a former lover, Janice Trahan, with HIV and Hepatitis C-tainted blood, claiming to be giving her a vitamin shot. Trahan developed both Hep-C and HIV as a result.

Worked examples

Example 1 — a first encounter with Pin prick attack

Start with the simplest possible case. Write down what Pin prick attack claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pin prick attack before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pin prick attack ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pin prick attack

In research
Pin prick attack appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Pin prick attack in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Pin prick attack is common in secondary-school and first-year university syllabi. It links to neighbouring topics American urban legends, Crimes, HIV/AIDS, so understanding it makes those chapters shorter.
In everyday life
Look for Pin prick attack outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
