Combating Disinformation in Public Health

Public health professionals work to educate and inform their communities.

In the public health arena, disinformation can prove life-threatening. And the COVID-19 pandemic has spotlighted just how dangerous it can be. Inaccurate information has led to vaccine hesitancy and the belief in dubious and dangerous treatments—part of what António Guterres, secretary-general of the United Nations, calls the “massive infodemic.”1

That’s why public health professionals are working to combat disinformation and misinformation. Because whether rooted in malice or ignorance, incorrect information imperils public health. Here are some of the strategies public health institutions are deploying to combat disinformation.

Identify Disinformation

Learning to sort fact from fiction is an important first step. The Union of Concerned Scientists suggests asking these questions to ascertain a claim’s veracity:2

  • Does it seem implausible?
  • Does it confirm your beliefs or play to your emotions?
  • Is it difficult to separate facts from opinions?
  • Does it ignore experts (from government or reputable public health organizations)?
  • Is the original source hard to pin down?
  • Does the source have a stake in the claim (financial, political, etc.)?

“If the answer is ‘yes’ to one or more of these factors, you may want to further scrutinize the information to determine its validity,” the organization writes on its website.2

Engage and Educate

“Stop Myths” is one component of the Centers for Disease Control and Prevention’s Vaccinate With Confidence campaign. “CDC is engaging local messengers and partners to contain the spread of misinformation and ensure key stakeholders have critical information about vaccines,” the organization says.3

The CDC plan, as stated on its website, is:3

  • Work with social media companies to promote trustworthy vaccine information.
  • Provide accurate, accessible information on vaccines to state policymakers.
  • Engage state and local health officials to advance effective local responses to misinformation.

Coordinate and Collaborate

In a March 2021 report, the Johns Hopkins Bloomberg School of Public Health and the Center for Health Security called for a national strategy to thwart false claims about COVID-19 and create a framework to prevent future disinformation campaigns.

The report, “National Priorities to Combat Misinformation and Disinformation for COVID-19 and Future Public Health Threats: A Call for a National Strategy,” outlined these top priorities:4

  • Intervene against false and damaging content as well as the sources propagating it.
  • Promote and ensure the abundant presence and dissemination of factual information.
  • Increase the public’s resilience to misinformation and disinformation.
  • Ensure a whole-of-nation response through multisector and multiagency collaboration.
