WASHINGTON, Nov 6, 2019 (BSS/AFP) – “How did I get chlamydia?” “Is this
herpes?”
People are increasingly turning to strangers on social network Reddit to
diagnose their sexually transmitted diseases, according to a new study
published in a US journal Tuesday that called the phenomenon “crowd-
diagnosis.”
Researchers from the University of California San Diego examined 17,000
posts on a Reddit thread devoted to STDs. They then analyzed a random sample
of 500 posts.
Fifty-eight percent of these messages explicitly requested a crowd-
diagnosis, while 31 percent included a picture of the symptoms.
One in five such requests come from users trying to get a second opinion,
after having consulted a doctor. These included the case of a person who
tested positive for HIV, but wanted to know what other Reddit users thought.
Eight-seven percent of the time, such requests received a reply, and fast:
the median time for a first response was three hours, with some receiving a
reply in less than a minute.
“Everybody talks about Dr Google all the time,” John Ayers, an
epidemiologist at UC San Diego and co-author of the paper published in the
Journal of the American Medical Association, told AFP.
“But the reality is searching for information online is not how people use
the internet anymore. They want to get real interactions with real people.”
But the problem, Ayers added, was that “crowd-diagnosis, as it exists now,
is wildly inaccurate and dangerous, but that doesn’t mean that we can’t turn
millions of people seeking diagnosis on social media into something good.”
He and his colleagues envisioned a future in which health care
professionals were available on social networks — not necessarily to make a
diagnosis based on insufficient information, but to make a first screening
and refer users to where they could get help — either at a clinic or via a
teleconference consultation.
“The reality is that in the longer term, the bigger picture is crowd
diagnosis could be a boon to public health information,” Ayers said, taking
the example of a subreddit devoted to suicidal thoughts.
“Trained experts are curating that Reddit, and they provide them
referrals,” he added.
