At the front lines of global health messaging: A conversation with WHO’s retired communications director | Harvard T.H. Chan School of Public Health

For decades, the World Health Organization has stood at the center of some of the most urgent and complex public health crises on the planet. Behind the scenes, crafting the words that reach billions of people is a delicate and often thankless task. In a recent conversation, the recently retired communications director for the WHO reflected on the immense challenge of delivering clear, trusted information while the world around it changes at breakneck speed.

The former director described a landscape where misinformation spreads faster than any virus. The job, they explained, is no longer just about issuing press releases or holding briefings. It is about building a bridge of trust between complex scientific data and a public that is increasingly skeptical and overwhelmed. Every word must be weighed for clarity, cultural sensitivity, and potential misinterpretation. A single poorly chosen phrase can spark panic or undermine years of public health work.

The conversation also touched on the personal toll of the role. During the height of the COVID-19 pandemic, the communications team worked around the clock, often facing intense political pressure and public scrutiny. The director noted that the most effective messaging is not about being the loudest voice in the room, but the most consistent and honest one. It requires listening as much as speaking, and admitting uncertainty when the science is still evolving.

As the media environment fragments into smaller, more niche channels, the challenge only grows. The former director stressed that public health communication must now meet people where they are, whether that is on social media, in local community centers, or through trusted family doctors. The goal remains the same: to save lives by giving people the information they need to make informed choices. But the methods, they said, must keep evolving, or the message will simply be lost in the noise.
