Coronavirus Alerts: Your phone can alert you if you are close to an infected person

11/27/2020 Health, Technology

While these apps can’t protect you – they let you know when you come out – after receiving a warning, they can prevent you from becoming infected if you take precautions like self-querying.

Millions of people are signing up, although these apps are not yet available in many states. Health officials believe that infected people can be especially helpful in cases where they have come in contact with strangers – for example on a bus, train or checkout line – who did not know they were exposed.

Unknown codes are constantly changing in iPhone and Android devices that ping nearby phones via Bluetooth – a process that begins after the user chooses to receive notifications.

For exposure notifications to be effective, Android users must turn on Bluetooth and download the Covid-19 notification app of their state. On the iPhone, even though the system is already baked in settings, users should go to exposure notifications and make sure availability alerts are turned on.

Close contact alert from the Covid-19 exposure instruction application created by the Nevada Department of Health and Human Services.

When a person who uses the symptom tests positive for coronavirus, she gets a pin from the health official to enter her phone. Any other phone that has been nearby in the past two weeks – usually at a distance of six feet or less, for at least 15 minutes – will receive a warning to quarantine the user and notify the health provider.

Apps assess your risk based on the strength of the Bluetooth signal (how close you were to the other person) and the duration of your contact with them.

Where you can get them

At least 15 states These Covid-19s are participating in the exposure notification system.

These include Alabama, Colorado, Connecticut, Delaware, Michigan, Minnesota, Maryland, Nevada, New Jersey, New York, North Carolina, North Dakota, Pennsylvania, Virginia, Wyoming and the nation’s capital, Washington DC.

Some states registered sign-ups within weeks of starting the program. Maryland launched its notification system on Nov. 10 and more than 1 million people have already signed up, said Charlie Gischle, a spokesman for the state Department of Health. He called the application “a complement to traditional contact tracing and another tool in the toolbox” to fight coronavirus infections.

In Colorado, where coronavirus cases and hospitalizations have occurred in recent weeks, more than 1 million people have signed up for the system since October 25th. The state has launched large-scale campaigns to educate residents about their exposure information service. .

Some states have launched applications to warn residents when they have been exposed to coronavirus.

Colorado Govt. “We are at a critical moment in this epidemic and choosing this service will keep our families and communities safe and our economy going,” Jared Police said in a statement.

Other states, including California and Oregon, have launched pilot programs, but their notification systems are not yet available to everyone.

Questions about privacy

Is the information from the apps anonymous? Experts say it is.

Apps do not collect data on users or their locations, and there is no way to combine covid diagnostics and alerts with names and identities over the phone, Gischle said.

Unlike previous notification systems, the epidemic initially used GPS, which tracks a person’s location, helping to maintain privacy and anonymity among Bluetooth system users.

“As opposed to tracking your location, the fact that you use Bluetooth to bounce signals to other nearby phones makes them less aggressive, and people shouldn’t have to worry about their location being tracked,” he said. Steve Waters, founder of Contress Public Health Corps, provides guidance on Covid-19 contact tracing.

“The process is completely anonymous and does not collect any personally identifiable information, given the privacy concerns of previous more aggressive contact tracing applications.”

Earlier versions that raised privacy concerns were created by third-party developers. This coronavirus notification alert technology has been provided by Apple Pal and Google, and users can choose to use it at any time, Gischle said.

Warnings Covid-19 can reduce infection

The more people who sign up for alerts, the more effective they are. Only a small percentage of the nearly 100 million Americans currently living in 15 states use apps.

But health officials say even this minimum number is making a difference. In Colorado, officials cited studies that show that 15% use of exposure notification technology also leads to a significant reduction in coronavirus infections and deaths. The state says their app usage is now at 17%.

According to Tony Enscombe, a global expert at Internet security company ESET, several states have teamed up to enable five-line notifications in a state line. This is especially important in places near the state border where people work in one state and live in another.

The alert system only works on phones that are less than five years old.

For example, New York, New Jersey, Pennsylvania and Delaware have formed a regional alliance that uses a similar system that allows their applications to operate across state lines, Enscombe said.

States face some challenges in spreading them

The warning system is designed to complement traditional contact tracing, not to work alone.

But technology brings its own set of challenges. For starters, the notification system only works on Google and Apple Plus phones that are less than five years old, An Nscombe said. Not everyone has a new smartphone, and a small percentage of those who do use the notification system.

The software on iPhone and Android devices detects when people - or rather - come close to each other.

In addition, not all states are using the notification system. Many state health departments are already overwhelmed by the resurgence of the virus, and some may not have the resources to develop and maintain the app, Enscombe said.

Earlier, the GPS-based notification system caused outrage among privacy advocates and raised suspicions about contact tracing in general, Water said.

“States need additional funding currently stuck in Congress to help dismantle the war and adopt this crucial tool in the fight against covid,” Waters said.

The coronavirus epidemic has also become a political issue, with some Americans taking it less seriously than others. For this reason, Waters said, there is also a reluctance to use some covid exposure applications.
