Infodemic

noun (also attributive/adjectival)
/ˌɪnfəʊˈdɛmɪk/
An overabundance of information — including misinformation and disinformation — during a disease outbreak that makes it difficult for people to find trustworthy sources and reliable guidance; the WHO identified the "infodemic" as a major challenge during COVID-19, as false claims about treatments, vaccines, and the virus's origins spread rapidly through social media.

✍️ Usage in a UPSC answer

During the pandemic, the State's challenge was twofold: containing the contagion itself while simultaneously battling an infodemic in which rumour, pseudo-science and communal canards travelled faster than verified advisories, eroding public trust in scientific institutions and complicating the public-health response.

🎯 How This Word Works in UPSC Writing

An overabundance of information during an outbreak, accurate and false together, which makes reliable guidance hard to find. Its value as a concept is that it identifies a public health problem rather than a merely journalistic one, because the harm is measurable: false claims about treatments cause direct injury, rumours depress vaccine uptake, and distrust of institutions reduces compliance with advisories, so an infodemic degrades the effectiveness of every other intervention deployed. The response, termed infodemic management, works on three fronts rather than by takedown alone. Accurate information is amplified so that it is easier to find than the false. Pre-bunking inoculates audiences by explaining the manipulation technique before they encounter it, which is more durable than correcting afterwards. And institutional trust is built, since it determines whether official advice is believed at all. The governance tension is that state suppression of false claims can itself erode that trust.

⚖️ Don’t Confuse It With

An infodemic is an overabundance of information during an outbreak, so it includes accurate material too and the difficulty is volume and navigability as much as falsity. Misinformation is false and shared without intent to deceive while disinformation is deliberate, and both circulate within an infodemic. Pre-bunking explains a manipulation technique before exposure whereas debunking corrects afterwards, and the first tends to be more durable. Vaccine hesitancy is one measurable outcome of an unmanaged infodemic.

Because false claims cause direct injury, rumours depress vaccine uptake and distrust reduces compliance with advisories, so it degrades the effectiveness of every other public health measure.
What is pre-bunking?
Explaining a manipulation technique to an audience before they encounter it, which inoculates against the message and tends to work better than correcting the claim after it has spread.
