A missing message in the swine flu story: the need to start explaining public health surveillance
Monday, July 13, 2009
We know from general media reports, and out own intercepts here in NYC most residents have heard about and understand the basic hygiene recommendations promoted for reducing risk of contracting swine flue:
- Wash hands thoroughly and frequently with soap and water
- Avoid contact with people who are obviously sick
- If you get sick with any cold or flu, stay home from work or school; avoid contact with others as much as possible
New York City Office of Emergency Management http://www.nyc.gov/html/oem/html/home/home.shtml
“What should I do to keep from getting the flu? First and most important: wash your hands. Try to stay in good general health. Get plenty of sleep, be physically active, manage your stress, drink plenty of fluids, and eat nutritious food. Try not to touch surfaces that may be contaminated with the flu virus. Avoid close contact with people who are sick.”

A concept that is hard to find in the BASIC information for the public is the story of public health and global health surveillance. The CDC site does refer to “EpiAid teams” being deployed, and “many epidemiological activities are taking place” and “active surveillance in the countries where infections in humans have been identified.”
But knowing what we know about low health literacy among the majority of adults in the US, and the complex concepts embedded in understanding surveillance, it’s safe to assume that people do not understand surveillance in ways that will help them place the current outbreaks in context, and help understand their risks better.
Why is public health surveillance important information for advancing public health literacy?
I was reading the NYT story (Saturday 5/3/09) “Questions Linger Over the Value of a global Illness Surveillance System” and “Flu Outbreak in Mexico May Be Smaller Than Feared” and in these well written pieces the journalists are telling the story of how the surveillance is unfolding – what kinds of information health experts and epidemiologists had early on in the swine flu outbreak, what they know now, and what information they’re expecting to have soon.
With a bit of science health literacy (that’s how I describe my literacy in that area), the stories put the outbreak into clearer, relative perspective. Key elements:
- There is an “expensive and evolving illness surveillance system constructed over the past decade.”
- The WHO plays a key role in global health surveillance and it has “ an extensive intelligence network of hundred of its own offices and thousands of experts.”
- The carefully follow up on reports anywhere in the world of clusters of acute respiratory illness (in this particular case). On April 17ththey uncovered a report “of an unusual case of pneumonia death in Mexico that was reported to be similar to those in China during an outbreak of SARS.”
- Multiple international organizations plan on “measures of cooperation.”
- One article concludes “ early warnings of even relatively mild, new flu strains are important.”
I think it’s vital to begin to tell the story of public health surveillance in a clear understandable manner. Without some understanding of this, and other science concepts, the public has limited ways to talk about and understand this and future outbreaks.
Question of the Day:
- Do you agree or disagree that this is an important message to get out?
- What could the information look and sound like?
