After three people died on a cruise ship hit by a hantavirusauthorities are actively monitoring 29 people who had left the ship. They try trace spread about this virus. It is a long, complex, international process to find and notify people who may be at risk of infection.
Hey, shouldn’t there be an app for that?
Address tracking programs were an international effort starting in 2020 time of COVID-19 a big disaster. Enabled by mobile companies like Apple and Googlecontact tracing was designed to use Bluetooth connections to identify when people came into contact with someone who had or would later test positive for Covid and report it further. It didn’t do much to solve the spread of the epidemic, but virus tracking was better at least. Such a process would not go well with the hantavirus problem.
“There is no use for programs for this hantavirus outbreak,” Emily Gurley, an epidemiologist at Johns Hopkins University, wrote in an email response to WIRED. “The number of cases is small, and it is important to trace all contacts specifically to stop transmission.”
With such small-scale infections, officials must start at the source (the infected person), then go person by person, verifying where they went and who they may have met. The data collected by the software from the multitude of devices would not be anywhere near accurate enough to give a good idea of where the virus might have hit until next.
Contact tracing on a large scale, like, say, a global pandemic, is less about tracking individual infections and more about understanding which parts of the population are susceptible, giving people the opportunity to free themselves after exposure. But that depends on how people choose to respond, and how technology is used by public emergency systems. During the Covid pandemic, contact tracing via software tended to work better in the more carefully managed European countries, but it didn’t. slow down the spread in the United States.
Making devices available for that kind of proximity information has also brought all kinds of concerns about privacygiven that the technology would require constant access to function properly. Address tracking also struggled to maintain accuracyand in some cases it may be giving false negatives or positives that do not help further information about the spread of the virus.
Especially in the case of something like Hantavirus, where everyone on that cruise ship can theoretically be tracked and communicated directly, it’s best to do the process diligently.
“During small but serious explosions, more precision is required,” Gurley wrote.
