Although “Infodemic” was coined in 2003 the word has never been more prominent than during the pandemic. Merriam-Webster’s Dictionary defines it as “a word that blends ‘information’ and ‘epidemic,’ and refers to the rapid spread of information – both accurate and inaccurate – in the age of the internet and social media.”
When Covid-19 started to spread rapidly, people wanted answers about what to do if they became sick with the virus. Their were plenty of websites and opinions on social media about different treatment options – some dubious – and others informative. Too much information can make it hard to determine what’s true and what isn’t. The World Health Organization remarks that an infodemic can “cause confusion and risk-taking behaviours that can harm health. It also leads to mistrust in health authorities and undermines the public health response.”
Infodemic appeared as early as February 2020 when an article written for TechnologyReview.com described coronavirus as “the first true social-media infodemic…the greatest source of anxiety has been the tortuous process of watching the news unfold on social media” (Karen Hao Tanya Basu).
