How Digital Contact Tracing Slowed Covid-19 in East Asia

Situated less than 90 miles from China, the coronavirus outbreak could have been critical in Taiwan, but the country's proactive measures helped to stave off the worst of the disease. Having learned from SARS epidemic, Taiwan had prepared for future situations by creating a comprehensive command center and implementing a transparent communication strategy both of which have helped slow the spread of Covid-19.

As the United States struggles to test all citizens exhibiting symptoms of coronavirus, Australia and Canada are offering lessons about best practices for preparing for a pandemic. Having learned from previous outbreaks, these countries implemented protocols such as a national hotline, easy-access to information about testing sites, and "an agency to coordinate and help finance testing and treatment during any kind of viral or disease outbreak" – all of which help make testing more efficient.

The testing efficiency and protocols implemented in South Korea to slow the spread of coronavirus have proven to be successful, with the latest reports of the country showing that reports of cases have leveled off. Combining "a single-payer health-care system and a sweeping infectious-disease law," the country was able rapidly identify potential cases and enact isolation in order to contain the spread of the virus.

Weeks before the coronavirus outbreak was declared to be a pandemic, Seoul, and other parts of South Korea set into motion a combination of "prevention and mitigation programs" that are now being touted as lessons for other countries struggling to contain the virus. Using technological advancements such as a national mobile phone alert system and mobile phone applications along with increased transparency around data collected, new reports of cases have slowed allowing the country to prepare for a potential surge later on.

South Korea is emerging as a model for many countries battling the spread of coronavirus, thanks to the country's quick response to initiate widespread testing and contact tracing methodology. Having learned from what failed during the outbreak in 2015, the country has been able to keep their death toll under 1 percent, unlike many other countries battling the pandemic.

As a grass-roots response to assist vulnerable populations amidst the COVID-19 pandemic, communities around the world are using social media to distribute supplies, services, and advice. One such group on Facebook, the Bristol Community Care - Covid-19 Mutual Aid, has gone viral with thousands of members seeking to help or receive help.

When virologists and genomicists in Seattle, Washington realized that COVID-19 was likely to spread to the United States, they began to research ways to keep vulnerable poplulations safe. So far, early success has come from replicating the Seattle Flu Study, which uses a swab test to "reveal the trail that the flu takes as it passes around households, homeless shelters, office parks and communities in the city," and now investors are putting money towards getting these tests into households.

South Korea has had an extremely effective response to the coronavirus because of its fast and widespread use of testing. There are now drive-through tests available where people recommended by their doctor can take a test from the safety of their vehicle. This decreases the chances of transmission and lowers the stress of both patient and doctor. As a result, the rate of increase has been slowing since February 29, 2020.

As word of the coronavirus outbreak spread, so did misinformation, so the World Health Organization began working with big tech companies to put a stop to it. Collaborating with the likes of Pinterest, Google, Twitter, and Facebook, W.H.O. has posted content that disputes the incorrect information across platforms and sites in order to make "falsehoods harder to find in searches or on news streams."

Identifying the metagenomic sequencing for new outbreaks of viruses can help to better assess how the virus is spreading, which in turn helps health officials figure out how to slow down the contagion. In the midst of a coronavirus outbreak, a tool that was first used to during the SARS outbreak is now being used to track Covid-19 in under-resourced places such as Cambodia.
