Contact tracing apps: Worth the hype?

Despite advancements in technology in most sectors of life leading to an increase to access of information about practically anything, little is still known about the ocean and its behavioral patterns. Liquid Robotics – a Silicon Valley-based company – is trying to change that. Engineers here have created the "Wave Glider," which essentially acts as a router within the ocean powered by wave energy and solar panels. This invention can transmit data on tectonic activity that has the potential to predict tsunamis.

To better position services during and after natural disasters, many nonprofits are turning towards mapping technology. Specifically, Facebook’s Disaster Maps share usage data to indicate movement, such as where people evacuated before Hurricane Florence. Humanity Road is another map source that includes data on infrastructure. Putting this information together, nonprofits such as Direct Relief can more accurately target their emergency response services.

Using data collection and visualization, apps like SafeCity, HarassMap, and #WalkFreely are crowdsourcing locations where individuals have been sexually harassed or assaulted so that others know to take precautions. Some operate on a global scale, others locally, but what they all offer is a platform for people to share their story and hopefully prevent it from happening again. Such apps have led to action from community members, the media, and officials who have taken notice of the high rates in certain places and taken action.

To reach kids who must stay at home as a result of the coronavirus and may not have access to reliable internet, teachers in Tennessee's Shelby County schools are recording easily accessible TV lessons. Though teachers can no longer get the same level of feedback from students or adjust to their on-the-spot questions, the lessons are to some degree interactive and aim to reinforce lessons students learned before schools went remote.

In Japan, the southwestern region of Kansai is less predicated by government oversight and relies more strongly on independence. In the Wakayama prefecture, that attitude has resulted in the region's leaders implementing an independent approach to battling the coronavirus outbreak. The approach, which utilizes widespread testing and contact tracing, is now being regarded by other regions as a model of success.

Scientists have been mapping microbes in public places for a long time and are now tracking Covid-19 by swabbing subways, park benches, ATMs, and even the air, for traces of genetic material to better understand the virus’ transmission dynamics and detect hotspots before transmission becomes widespread. Molecular monitoring has identified how long the virus can live on different surfaces and the origin of different strains, which can flag sanitation priorities and help contact tracers. There are limits to what it can reveal because finding virus on surfaces does not always lead to definite infection.

Health officials in North Carolina have shown that contact tracing can successfully identify those who have been exposed to COVID-19. The efforts of the contact tracers in one county resulted in 35 people being quarantined after an exposure to the virus during a child's birthday party, however that was only possible because of those individuals "were willing to be open and honest and forthcoming."

In an effort to help get accurate information to the communities who are being disproportionately impacted by the coronavirus pandemic, a program called Live Chair Health has started to train barbers "on chronic issues that disproportionately affect Black communities" and teach them "how to have conversations with their clients about the diseases." Aside from providing COVID-19 information, the initiative has helped patrons access primary care and address other medical issues such as high blood pressure.

A growing number of governments, companies, and nonprofit organizations are working together with new technology and data to identify fishing vessels that are breaking laws and engaging in human rights violations. Using satellite imagery and tracking signals, for example, a philanthropic company and a nonprofit worked with the UN Office on Drugs and Crime to help the Ghanian navy arrest four vessels for illegal fishing practices. Technology by itself won’t stop forced labor and unregulated ships, but it can be helpful for cash-strapped governments looking to increase oversight of their fisheries.

To discourage the spread of misinformation about the Covid vaccine and decrease vaccine hesitancy in minority communities, religious leaders and other influential people in Britain have launched campaigns to dispel concerns. According to a survey about overall willingness to take the vaccine, the efforts – which include posters, sermons, a help line, and WhatsApp chats – have been working.
