The poll found that a majority of adults (89 percent) said they would likely follow public health officials’ initial recommendations to go get antibiotics from a dispensing site after an anthrax attack. Among parents, 91 percent said they would be likely to go get the antibiotics for their children. Of adults who said they would be “very likely” to go to the sites, the vast majority said they’d go even if they knew they had to wait in line for two hours (94 percent).
However, the poll also finds that a sizeable minority of adults may not follow through on the public health recommendations. Of adults who said they were likely to go to the sites, only a little more than half (57 percent) said they would start taking the antibiotics right away. Thirty-nine percent said they would hold on to the pills and either wait to take them until they found out if they were truly exposed to anthrax (35 percent) or for the foreseeable future (4 percent). The responses of parents intending to get the pills paralleled these results, with 60 percent of those who were likely to go to the dispensing site saying they would start giving their children the pills right away, while 38 percent saying they would hold on to the pills and either wait to see if their child was truly exposed (36 percent) or for the foreseeable future (2 percent).
“It’s concerning that some people will not take the antibiotics after picking them up at the dispensing site because such ‘wait and see’ behavior could put those who were exposed at greater risk for serious illness or even death in the event of this kind of anthrax attack,” said Gillian SteelFisher, research scientist in the HSPH Department of Health Policy and Management and assistant director of the Harvard Opinion Research Program. “Experts believe that antibiotics have the greatest effect when started quickly — before any clinical signs of disease — and this may be before people are certain they have been exposed.”
The poll results also call attention to potential areas of resistance to public health recommendations by examining the reasoning among those who said they were unlikely or only “somewhat likely” to go get antibiotic pills at these dispensing sites (for themselves or for their children); this included roughly a third (34 percent) of people. This group most often cited worries about officials being unable to control crowds (45 percent) as a “major reason” for their decision. Other major reasons were that they would: worry about being exposed to anthrax while going to a dispensing site (41 percent); worry that there would not be enough antibiotics (40 percent); worry about the safety of the antibiotics (38 percent). Some also said that they would wait to get antibiotics until they were sure they truly had been exposed to anthrax (37 percent).
While a majority of the public said they were confident in the government’s ability to deliver antibiotics quickly to everyone in their city or town, it is notable that a sizeable minority did not agree. Nearly two-thirds (63 percent) were confident that there would be a sufficient supply of the antibiotics for everyone in their city or town who wanted them, but a third (36 percent) were not confident.
The poll also included people living in areas that actually experienced anthrax attacks in 2001 (Washington, D.C., Trenton/Mercer County, N.J. and New York City). The poll found that people from these areas had similar responses to the nation as a whole, but there are notable differences in responses to two questions. Adults from the D.C. metro and Trenton/Mercer County regions were less likely than those in New York City or nationally to be “not at all familiar” with the term “inhalation anthrax” (13 percent and 15 percent vs. 22 percent and 21 percent respectively). In addition, upon hearing the scenario concerning possible anthrax attacks in their city or town, people in the D.C. metro, Trenton/Mercer County and New York City metro regions were all more likely than people nationally to expect the event to be an isolated incident (40 percent, 42 percent, 37 percent vs. 27 percent) rather than part of a series of attacks.
This poll is part of an on-going series of surveys focused on the public’s response to public health emergencies by the Harvard Opinion Research Program (HORP) at Harvard School of Public Health. It is the second poll focused on anthrax specifically, following a poll conducted in 2001 concerning the worries and behaviors of people in three metropolitan areas following reports of multiple anthrax attacks in those locations.
