HIFA social media (X) volunteers and your thoughts on Bluesky (5) X/Twitter

22 September, 2026

Dear Neil & HIFA colleagues,

I'd like to follow on from the message from Chris Zielinski (https://www.hifa.org/dgroups-rss/hifa-social-media-x-volunteers-and-your...). I'm sure many share his depth of feeling and are tempted to leave X/Twitter (if they haven't already done so).

Nevertheless, many health professionals, researchers and organisations (such as WHO) still use X/Twitter to share research, guidelines, outbreak information and public health messages.

I wonder how much X/Twitter retains among HIFA members these days?

A recent Lancet article, “The paradox of trust in health care in the age of social media” (Ienca, Gounder & Emanuel, 2026*), discusses how social media can change the relationship between expertise, credibility and trust.

And a 2025 study** examined health information about COVID-19 on Twitter/X, including how trustworthy information and misinformation might be distinguished.

I'd like to ask HIFA members: What is YOUR experience?

• Do you still use X/Twitter for health information in your workplace?
• In general, what makes you trust a health-related account or post?
• Do you check information against other sources before sharing it?
• Has your trust in X/Twitter as a source of health information changed in recent years? And if so, why?
• What value do you see in X/Twitter in relation to health information?
• Is X/Twitter particularly useful for connecting health professionals and sharing information across countries?

We'd love to hear examples - both positive and negative. What other thoughts do you have?
