COVID-19 Contact Tracing

Overview

Faced with one of the most unprecedented challenges of the 21st century, COVID-19 brought the world to a halt. Masks and contact tracing were two solutions that were explored to curb the spread of the virus. Due to the ever changing nature of the virus, contact tracing proved to be a way to keep tabs on the spread. Contact tracing, as described by the CDC, “ [I]s an effective disease control strategy that involves identifying cases and their contacts then working with them to interrupt disease transmission” (“Contact Tracing – CDC’s Role and Approach”). When done effectively, contact tracing can significantly slow the spread of COVID-19. The use of technology has been explored heavily as an option to reduce the long and tedious manual work done by human contact tracers. Along with this, comes ethical concerns regarding privacy and citizen rights.

The Process

The process of contact tracing involves multiple steps involving the positive patient, contact tracers, and close contacts of the positive testing individual.

• ALL of this information is taken from the CDC website*

STEP1: First, the positive patient should contact everyone who they have been in close contact with and notify the appropriate party (contact tracers). The contact tracers will ask you about your recent whereabouts and if you could have transmitted the virus. If you are one of the people who have been identified as a close contact to someone who tested positive, you should receive a call from a contact tracer notifying you of this exposure and request that you get tested as soon as possible.

STEP 2: It is recommended that you quarantine for fourteen days after the possible exposure.

STEP 3: Take a PCR Covid-19 test. If the result is positive, refer to step 1 of the process.

STEP 4: Make sure to monitor your health and temperature throughout the self-isolation time to ensure no (new) symptoms have arised since the beginning.

Ethical Concern Overview

Contact Tracing is done differently around the world- some countries choose to respect individual privacy above all else, whereas some choose to prioritize the health of the community. Much of this controversy over privacy concerns stems from digitization. Although the concept of contact tracing has been around for many years, people worry that digitizing it will impede on their privacy. How might governments balance their citizens’ right to privacy with the need to protect community health?

Government Intervention

China Various government systems have handled digital contact tracing differently. China, a socialist country, has drawn praise for its ability to slow the spread of the virus. China is successful because it is able to aggressively monitor its citizens due to its form of government. Alipay, a robust platform that has dominated the webspace in China, has proven to help streamline digital contact tracing. Alipay and company, Ant Financial, developed a way to determine the COVID risk of individuals by using data such as travel history and private encounters (Huang et al.). Citizens must download a wallet app called Alipay in order to use the contact tracing software. Coined as Alipay Health Code by the Chinese news platform, this software gives people a color (red, yellow, or green) indicating whether they can enter a facility or if they have to go home and quarantine. This is determined by information that is filled out by users prior to entering a public space. After filling out the information, they are presented with a QR code with one of the three colors based on the data collected through the form as well as previous travel history and contacts. Green indicates that an individual is safe to enter a building and is not a risk. Yellow signifies that they may be at risk because of close contacts or symptoms and should be prepared to quarantine for a week, if necessary. Finally, red means that the individual should quarantine immediately for two weeks as someone they have come in contact with contracted COVID-19. According to sources and analysis from the New York Times, Alipay also shares this data with law enforcement. In an effort to make sure that as many citizens are tracked as possible, the government, in collaboration with Ant and Alipay, have been working to make it necessary to register oneself before entering public spaces. When the QR code is scanned, the software tracks that the individual was in that location in case of potential spread. Government officials have not provided adequate explanations as to how exactly they get the data to assign individuals to colors. All that is known is as soon as an individual allows the Alipay Health Code software to look at personal information and data, citizens are sharing virtually all of their information with head authorities. Many citizens are left frustrated and confused as they may not know why their color has changed from green to red in a matter of a day. In many cases like this, residents are not able to travel and must cancel plans at the last minute. Some citizens argue that this software already possesses much personal data, so having this system in place does not change much besides attempting to curb the pandemic. However, some believe that it is an utter invasion of privacy, as various government officials are able to access their data with little to no explanation of how the system actually works. In a country where digital privacy is nearly nonexistent and personal data searches have sent citizens to prison, how reasonable is it for the government to completely bypass citizens’ privacy for the sake of health safety?

United States On the other end of the spectrum is the United States where personal freedom, liberty, and privacy are constitutional rights. Here, digital contact tracing with limited privacy deems improbable. Despite cases topping over twelve million, there is no national digital contact tracing system in place. As a result, states such as North Dakota, Alabama, and South Carolina are handling matters at a state level with two private companies, Apple and Google. Rather than implementing a more centralized system like China, these states, working with Apple and Google, have devised a plan for a more localized system using bluetooth technology. Many of the residents of the United States possess either Apple or Android mobile products. Due to the nature of the background ioS and Android technology, other companies would struggle to use the bluetooth feature, as it is blocked from background use. Using Apple and Google’s technology, state health officials are developing apps with specific privacy measures such as limited data access and disabled GPS capability. More specifically, the technology will not be able to locate a user’s specific location and will not allow government officials access to override the GPS setting, ensuring more privacy. In addition, the information collected through this technology can only be used for tracking purposes, not for profit and/or advertising purposes. Since the release of this technology, twenty-two other countries and countless states have submitted a request to Apple and Google for use of the technology. However, some states have chosen to stray from the idea of a more localized system. Utah, for example, has adopted a method that relies heavily on location sharing. Officials there believe that the best and most effective way to contact trace would be to have residents share data regarding location to contact tracers. This is a more centralized approach as the wide array of contact tracers would have access to this data (Leswing). Much of the work done by Apple and Google has sharply contrasted China’s aggressive digital contact tracing platform, which justifies limiting privacy for public health. States that follow this same rationale believe that tracing would not be as efficient with all the privacy measures that Apple and Google planned to put in place. Can the United States push the boundary of privacy, while still respecting the rights of citizens, in order to develop a successful system?

South Korea

When dealing with a problem as large scale as COVID-19, government officials have the difficult task of balancing safety with the privacy of their citizens. Some nations, like China, with the use of Alipay Health Codes, have put their full trust in the government and its ability to make safety their priority. Other countries, like the United States, are still developing a system that holds equal importance to both safety and privacy. Some states chose to utilize Apple and Google's technology to attempt to digitize contact tracing while respecting privacy. Whereas, some states looked to a more centralized approach, similar to China, to make contact tracing more effective. South Korea has found an effective and more moderate way to curb the spread using digital contact tracing by; Nevertheless, as more lives are lost every day, government officials continue to search for the right balance to deliver an effective digital contact tracing solution.
