Misconceptions and the Spread of Infectious Disease

New and improved medical treatments for infectious diseases are vital to improving global health security; however, public education is equally important. Myths and misperceptions regarding infectious diseases have detrimental effects on global health when a disease outbreak occurs. While it may seem that this problem is isolated to remote regions of the developing world, neither infectious diseases nor misconceptions regarding them are explicitly confined to certain areas.

Outbreaks can be highly disruptive to the movement of people and goods, often leading to increased regulations and restrictions on travel and trade to reduce the potential for further spread of disease.1)Eco Health  Alliance. “7 Common Myths About Pandemics and New Diseases.” Last modified June 27, 2013.

The disease quickly infected thousands of people around the world and disrupted national economies.3)Ibid. Due to the rapid transmissibility of SARS, the World Health Organization (WHO) issued a travel advisory in effort to reduce the international public threat.4)Ibid. In 2001, the United Kingdom experienced a detrimental hit to the agricultural sector as foot-and-mouth disease spread throughout livestock.5)BBC. “Foot-and-Mouth Crisis Remembered.” Last modified February 17, 2011. Accessed on May 13, 2014. http://www.bbc.com/news/uk-england-12483017 Because of the highly transmissible nature of the disease (which affected cattle, pigs, sheep, and goats), the government banned all exports of live animals, meat, and dairy products in an effort to mitigate the spread of the disease and on February 24, mass slaughtering of pigs and cattle began.6)Ibid. Later that same year, the tourist industry estimated that businesses lost nearly £250 million ($421 million U.S. dollars).7)Ibid.

In the developing world, pneumonia, diarrhea, malaria, measles, and HIV/AIDS8)UNICEF. “Immunization: Why Children Are Dying.” Accessed on March 19, 2014. http://www.unicef.org/immunization/index_why.html are some of the primary causes of death, especially among children. This is in part attributable to socioeconomic factors that prevent people from having access to routine health services and immunizations. Poor nutrition and unsanitary living conditions also place people at-risk. In Africa, the death rate among children from measles, a viral respiratory disease, has reached an average rate of one per minute.9)Ibid.  Measles weakens the child’s immune system, rendering them susceptible to further fatal complications such as diarrhea, pneumonia, and malnutrition.10)Ibid. Yet, in the developed regions of the world, measles is commonly treated through immunizations.

Tetanus, an infection caused by the bacteria Clostridium tetani (which is ubiquitous in the soil),11)Medical News Today. “What is Tetanus? What Causes Tetanus?” Last modified Sept. 4, 2009. Accessed on March 19, 2014. http://www.medicalnewstoday.com/articles/163063.php  is common in developing areas that continue to practice unsanitary medical techniques during procedures such as child birth, circumcision, and use of contaminated medical bandages during such procedures.12)UNICEF. “Immunization: Why Children Are Dying.” Accessed on March 19, 2014. http://www.unicef.org/immunization/index_why.html 13) Medical News Today. “What is Tetanus? What Causes Tetanus?” Last modified Sept. 4, 2009. Accessed on March 19, 2014. http://www.medicalnewstoday.com/articles/163063.php While proper sanitary resources are scarce in these regions, it is evident that the lack of supplies is not the only cause of disease transmission as proper sanitation techniques could have mitigated transmission. Due to the lack of education and misinformation regarding public health, sanitation, and the mechanisms of disease transmission, the spread of infectious diseases like tetanus continues.

Developed countries are also susceptible to infectious disease outbreaks despite modern medical advances and technology. Disease outbreaks in developed regions have been due in part to the misconceptions of vaccines and anti-bacterial drugs that have been used to deter the spread of infectious diseases. While some individuals have the perception that antibiotics are a “cure-all” drug, their effectiveness is only on infections caused by bacteria, not viruses. When improperly used (for example- taking when they are not needed, ingesting the wrong type of antibiotic or one that is not of the proper dose), the bacterial cells that survive can result in reinfection or the emergence of an antibiotic-resistant strain of the bacteria.14)Mayo Clinic. “Antibiotics: Misuse Puts You and Others at Greater Risk.” Last  Modified 2014. Accessed March 20, 2014. http://www.mayoclinic.org/healthy-living/consumer-health/in-depth/antibiotics/art-20045720 15)Koo, Ingrid. About.com, “The Truth About Antibiotics.” 6 Nov. 2008. 6 Apr. 2014. http://infectiousdiseases.about.com/od/treatment/a/antibiotic_myth.htm This was evident in the recent reemergence of pertussis, also known as “Whooping Cough,” in the mid-1970s when Great Britain, Sweden and Japan reduced their usage of the pertussis vaccine as there was a common fear of vaccinations. The effect was immediate and drastic- there were over 100,000 cases and 36 deaths in Great Britain, 13,000 cases and 41 deaths in Japan, and 3,200 cases in Sweden.16)Center for Disease Control. “Some Common Misconceptions About Vaccination and How to Respond to Them.” Last modified Feb. 18, 2011. Accessed on March 19, 2014. http://www.cdc.gov/vaccines/vac-gen/6mishome.htm The United States witnessed a similar outbreak in the northwest region of the country in 2012, when over 17,000 cases emerged shortly after an increased rate of vaccine refusals for pertussis.17)Forbes. “Anti-Vaccine Movement Causes The Worst Whooping Cough Epidemic in 70 Years.” Last Modified July 23, 2012. Accessed on March 19, 2014. http://www.forbes.com/sites/stevensalzberg/2012/07/23/anti-vaccine-movement-causes-the-worst-whooping-cough-epidemic-in-70-years/ While no vaccine is 100% effective, it is evident that popular misconceptions regarding infectious diseases and their spread can have detrimental repercussions on the populace and need to be addressed head-on.

Education, early detection, and access to are all essential in containing and preventing the spread of disease in a globalized society. Myths and misconceptions have hindered the effectiveness of vaccinations, as individuals have become skeptical of their effectiveness. However, vaccinations can drastically reduce the chances of contracting many diseases.18)Mayo Clinic. “Infectious Diseases.” Last modified    Jan. 23, 2013. Accessed on May 23, 2014. http://www.mayoclinic.org/diseases-conditions/infectious-diseases/basics/prevention/con-20033534 Additionally, developing and utilizing programs that educate the public regarding the implications of infectious diseases and treatments pertaining to them, the spread of disease is likely to be significantly reduced.

Infectious disease outbreaks are a significant threat to global health security and thus have the potential to impact nearly every facet of daily life. Even in an era of medical advancements, increased sanitary practices, and knowledge of microbes, infectious diseases are still prevalent throughout the world. While having better medical practices and medicines available is beneficial in combating the transmission of infectious diseases, there is no substitute for better public health education.

Examining Global Biosecurity Engagement Programs

Global biosecurity engagement programs are designed to prevent the harmful use of biological agents and pathogens. It is difficult to measure the effectiveness of these programs in improving biosecurity given that there have been relatively few attempts to misuse the life sciences. Metrics that focus on outputs (what was done) as opposed to outcomes (the impact of what was done) have not been helpful in determining how these efforts might be improved in the future. As a result, the goals of the programs have traditionally been more quantitative in nature – for example, increasing the number of agents secured and number of scientists engaged. Broadening the scope of biosecurity engagement metrics can help align program goals with a more qualitative approach that prioritizes the international partners’ global health security.

To understand how biosecurity engagement is conducted and evaluated, Michelle Rozo, Ph.D. candidate at Johns Hopkins University, interviewed more than 35 individuals in the United States and abroad (including government officials and their non-governmental partners) regarding current and future programs that can be used to create a cohesive, global health system approach to biosecurity. The results from the interviews are complied in an issue brief which also provides a strategy for policymakers to focus more on qualitative public health outcomes instead of quantitative security outputs. With this strategy, programs will cost less and be more effective in reducing global threats.

The History and New Directions of Biodefense

Dr. Matthew Meselson, a Harvard biologist and longtime advocate for biological disarmament, (and a  member of FAS’s Board of Sponsors) spoke Tuesday, June 26th  at a briefing hosted by FAS in Washington, D.C. on the recent history of biodefense and the need for oversight on biodefense efforts.

“Infective agents don’t stop at frontiers. They don’t have passports,” Meselson said. A biological attack against any nation, or a virulent disease outbreak can threaten the entire world.

Though President Richard Nixon renounced biological weapons on November 25, 1969, the decision had begun several years earlier, notably in 1963 when Secretary of State Dean Rusk began asking about  the potential for banning biological weapons.

In 1968, the Department of Defense looked deeper into the nation’s biodefense and BW programs and at first proposed a stronger BW and chemical weapon programs. At the time, the U.S.’s BCW programs were too small to be viable.

“Why would you want something that was small and not very good? The likely thing is that you would want something that is good,” Meselson said.

At about the same time, DoD officials in the Office of Systems Analysis investigated the strategic use of biological weapons and the threat of proliferation. They found there were no potential applications of lethal biological weapons that were preferred to the use of nuclear weapons. And the scenario for non-lethal biological weapons was so unlikely that non-lethal biological weapons were not worth it.

1. Smallpox Destruction Gets Deferred

On May 24th, 2011, after much anticipation and debate, the World Health Assembly agreed to postpone the destruction of the last known stockpiles of the smallpox virus until 2014. The consensus was reached after two days of deliberation at the 64th World Health Assembly (WHA), the 193 state-comprised forum of the World Health Organization (WHO), which took place from May 16-24, 2011 in Geneva.

Smallpox, a deadly infectious disease caused by the Variola major and Variola minor viruses, was declared globally eradicated over 30 years ago. Live samples of the virus have since been securely held at two WHO repositories in the U.S. and Russia for research purposes. The decision to destroy the remaining stocks was first put forth in 1996 and has since been repeatedly postponed. Continue reading
