Spotting Misinformation About COVID-19 and the Coronovirus

Every day there’s new and sometimes conflicting information and research coming out about COVID-19 origins, prevention, symptoms, treatments, and potential cures or vaccines. Unfortunately, medical misinformation is spreading even faster. This issue has become great enough that the U.S. Surgeon General issued this advisory, Confronting Health Misinformation: The U.S. Surgeon General's Advisory on Building a Healthy Information Environment. Sometimes, scientific studies are badly misinterpreted. At other times, information is more deceptive or blatantly wrong. Buying into misinformation could lead to dangerous consequences for your health and the health of your loved ones.

The next time someone shares a COVID-19 ‘fact’ via text, social media, or clickbait, verify it before you share it! The tips can help you protect yourself from the COVID-19 infodemic

Guide structure

This first page includes key evaluation strategies and resources. The next three pages offer tips for evaluating information in particular source formats (social media, news articles, scholarly articles). Finally, Evaluating Online Sources Guide goes to a separate guide relevant to evaluating online sources on any topic.

Evaluation Strategies

Here are ways to read beyond the headline (or copied + pasted Facebook post):

a) Check the source(s)

  • Is a link or citation to any studies mentioned? Or is there only a vague line about ‘’science says...” or “studies show…”?
  • Note the date of the article or social media post. With thousands of COVID-19 papers coming out weekly, the information could soon be out-of-date.
  • Given the urgency, there can be much excitement about a single study, and is often taken as definite proof. Though promising at first, the study cited could have since been discredited (e.g. as was the case with one of the first studies on the antimalarial drug hydroxychloroquine).

Pro tip: Double check the study that’s being cited to see if it’s been red-flagged in Retraction Watch’s COVID-19 section.

b) Check what other trusted places report  

  • Have the same findings been reported in many credible media outlets? Or are you only seeing this on social media or just one news site?
  • Do other medical or public health experts provide their opinion and explain what the findings could mean for the real world? Just ONE study on 10 people ≠ what works for the general population.
  • Even if a political figure states something about COVID-19, they could be misinterpreting scientific studies, or misrepresenting the findings to serve a political agenda.

Pro tip: Fact check the statement using non-partisan sites like FactsCan or

c) Scan for bias and deception in the tone, word choice, and images

Pro tip: Use a reverse image search engine to figure out if it’s been altered or taken out of context, with tools like Google Reverse Image Search, TinEye, YouTube Data, or Serelay.

d) Check the credentials/reputation of the researcher

  • Dig even deeper into the expert being cited! Even if their credentials seem legitimate at first glance (e.g. a PhD or an MD), do a Google search to see their reputation among other experts. Has their research been strongly supported, or widely debunked? 

Pro tip: Search for the expert’s name along with keywords like ‘retraction’, ‘fabrication’, ‘falsified data’, ‘scientific misconduct’, ‘pseudoscience’ or ‘conspiracy theory.’
