Coronavirus alerts: Your phone can notify you if you are near an infected person

USA NewsDesk November 26, 2020 01:52

Although these applications may not keep you safe – they will only let you know after exposure – they can prevent others from becoming infected if you take precautions, such as self-quarantining, after receiving a warning.

Millions of people log in, although these apps are not yet available in many states. Health officials believe alerts can be especially useful in cases where an infected person has been in contact with strangers – such as on a bus, train or checkout – who otherwise did not know they were exposed.

IPhones and Android devices contain ever-changing anonymous codes that ping nearby phones via Bluetooth – a process that begins when a user chooses to receive notifications.

For exposure notifications to be effective, Android users must turn on Bluetooth and download their state’s Covid-19 notification app. On iPhones, the system is already turned on in settings, although users need to display exposure notifications and make sure availability alerts are turned on.

A close contact alert from the Covid-19 Exposure Notification Application reported by the Nevada Department of Health and Human Services.

When someone who uses this feature proves to be positive for the coronavirus, they will receive a PIN from a medical officer to access their phone. Any other phone that has been nearby in the previous two weeks — usually within six feet or less for at least 15 minutes — will receive a warning in which the user is quarantined and notified to the health care provider.

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

Where to get it

At least 15 states participate in this Covid-19 exposure reporting system.

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

Some states reported enrollments within weeks of launching the program. Maryland launched its notification system on Nov. 10 and more than a million people have already registered, said Charlie Gischlar, a spokesman for the state health department. The application to combat coronavirus infections has been described “as a complement to traditional contact tracking and as another tool in the toolkit.”

In Colorado, where coronavirus cases and hospitalizations have increased in recent weeks, more than 1 million people have also reported alerts since the October 25 system was launched. The state is one of a number of campaigns to inform residents about their exposure notification service. .

Some states have launched applications that alert residents when exposed to a coronavirus.

“We are at a key moment in this pandemic, and using the service will help ensure the safety of our families and communities and the functioning of our economy,” Colorado Governor Jared Polis said in a statement.

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

Privacy issues

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

The apps don’t collect data about users or their whereabouts, and there’s no way to link Covid’s diagnoses and alerts to the names and identities of phones, Gischlar said.

Unlike a previous GPS-based notification system, which was widely advertised at the beginning of the epidemic, that tracks a person’s whereabouts, the Bluetooth system helps maintain users ’privacy and anonymity.

“The fact that they use Bluetooth to reflect signals from phones near you, rather than tracking your location, makes them less invasive and people don’t have to worry about tracking their location – it’s not” – He told. Steve Waters, founder of the Contrace Public Health Corps, who provides guidance on tracking Covid-19 exposure.

The vehicles line up this month at the coronavirus testing center in Miami Gardens, Florida.

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

Earlier versions that raised privacy concerns were created by third-party developers. This corona virus notification alert technology is provided by Apple and Google, and users can stop using it at any time, Gischlar said.

Alarms can reduce Covid-19 infections

The more people subscribe to alerts, the more effective they are. Currently, only a small percentage of the roughly 100 million Americans living in the 15 states use the apps.

But even that minimum number will change, according to health officials. In Colorado, officials cited studies that show that up to 15% use of exposure reporting technologies significantly reduces coronavirus infections and deaths. According to the state, the use of their application is currently 17%.

Some states have been grouped to allow pop-up notifications on state lines, according to Tony Anscombe, a global expert at ESET Internet security company. This is especially important near state borders, where people work in one state and live in another.

The alarm system only works on phones under five years old.

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

States face some challenges in disseminating them

The alarm system is designed to complement traditional touch tracking and not work alone.

But technology has its own challenges. For starters, the notification system only works on Google and Apple phones under the age of five, Anscombe said. Not everyone has a newer smartphone, and only a small percentage of them use the notification system.

Software on iPhones and Android devices detects when people - or rather their phones - get close to each other.

In addition, not all states use the notification system. Many public health departments are already inundated with the virus’s resurgence, and some may not have the resources to develop and maintain an application, Anscombe said.

The previous GPS-based notification system has sparked outrage among data protection advocates and sparked skepticism about contact tracking in general, Waters said.

“States need additional funding, which is currently stuck in Congress, to help combat disinformation and increase the use of this critical tool in the battle against Covid,” Waters said.

The coronavirus epidemic has also become a political issue, with some Americans taking it less seriously than others. Therefore, Waters said some are also reluctant to use Covid exposure applications.
