Covid-19: Five Scenarios for Using a Public Warning System

According to the European Centre for Disease Control  there have been over 2.6 Million cases of COVID-19 in Europe since the start of the pandemic in December 2019, representing 15% of the global total.  Russia (739 947), the United Kingdom (291 373), Spain (256 619), Italy (243 344) and Germany (199 726) have reported  the most cases.   Almost 198,000 deaths have been recorded in Europe with the most occurring in the United Kingdom (44 968) followed by Italy (34 984), France (30 029), Spain (28 409) and Russia (11 614).

With the exception of Bulgaria and Romania, the 14-day case notification rate as of 10 July (ref 3) reveals a downward trend across Europe with the death rate showing a similar pattern (Ref: ECDC report)

Many countries have chosen to ease some lock-down restrictions to enable businesses to operate and for people to live a more normal life. However, this renewed freedom could result in sudden spikes in infection rates and the prospect of a much larger second wave as winter approaches. Indeed, many countries are seeing COVID-19 hotspots emerge on a local level.

In Spain, the region of Catalonia was the second-most affected region after Madrid and is now facing the highest number of new infections.  France, Italy, Germany, Greece and the UK have all had localised outbreaks in recent weeks and in eastern European countries are facing rising waves of coronavirus infections, leading to riots in Serbia, mandatory face masks in Croatia and travel bans or quarantines imposed by Hungary (see Euronews 12 July).

It is clear that governments are facing a long-term roller-coaster ride to contain local COVID-19 outbreaks and prevent a repeat of countrywide lock-downs.

How can public warning technology be used to keep people safe?

Several countries have chosen to invest in technology that uses smartphone apps to support track and trace programs. For these to be effective, the population needs to download and use the apps. Studies from Oxford University suggested 60% adoption is needed, yet no country has been able to achieve this so the value of such apps is in question.

During this long-term crisis, people will be reliant on accurate and trusted information from government leaders. However, many countries are failing to communicate effectively with people at risk and provide guidance on safe areas and the changing rules for day to day living with the threat of COVID-19.

Mobile phones are used by over 85% of the population, and yet most European governments are not using public warning technology to directly warn and inform the public using the mobile network to send information via text messages. This can done using 2 technologies:

  • Cell Broadcast (CB)
  • Location Based SMS (LB-SMS)

National public warning systems are in place in just a few European countries today, the Netherlands, Greece, Iceland, Belgium, Sweden, Norway are all using the mobile phone networks to warn and inform the public during COVID-19.

A public warning system (PWS) can communicate the right information to the right people at the right time and in the right place – using the right channel.

Below are 4 scenarios during the COVID-19 pandemic where a PWS could be used to send targeted messages to everyone in a specific geographical area.

1. A localised lock down is ordered to manage a new outbreak.

2. A city is put back into lock-down.

In addition to informing local residents, the authorities also need to contact people who visited the city recently to advise them to self isolate or go for a test.

  • LB-SMS

3. Managing Crowded Places

Lock-down is eased, the authorities need to maintain social distancing in public places including parks, city centres or beaches.  The PWS can be used to visualise the change in crowd movements over time by showing on a map how many mobile devices are in the defined area.  This makes it possible to monitor when a crowd is reaching dangerous levels which will increase the risk of the virus spreading.

The PWS can then be used to send alerts as follows:

The Right Channels

  • People approaching a crowded area.

  • Digital signage
  • Radio, TV
Alert the public to disperse from the crowded area
  • People already within a crowded area.

  • SMS
  • App

4. Communicate with travellers in overseas locations where a lock-down is declared.

When a country declares a new local or national lock-down there will be be people in that country who are visitors from overseas.  A PWS that uses location based technology makes it possible to see exactly how many citizens from your own country are in the affected foreign destination.  The authorities can then contact those citizens through the mobile phone network to provide information and assistance.

  • Voice calls to mobiles

  • Throughout the lock-down period

Provide information on how to repatriate or contact the authorities for help coming home.

  • Throughout the lock-down period

Provide an all clear once the threat is no longer there.

  • After lock-down is lifted

5. Foreign nationals (inbound roamers) visiting your country from overseas

This is the reverse situation from the previous example.   In this case the authorities can identify the nationality of overseas visitors that arrive at their own border and provide information or instructions to those users in their own native language.  These people can also be sent follow up messages during their stay, should the situation change.

Summary:

European countries have 2 years to implement a public warning system under EECC Article 110, yet with the ongoing threat from coronavirus, there is a more urgent need for good public communication.

Everbridge has spent 20 years developing public warning solutions. Cell Broadcast and Location-based SMS are robust, reliable technologies for warning and informing the public.

Everbridge is the recognized expert in providing public warning solutions and our alerting platform has been used by governments to send millions of messages to the people of the Netherlands, Greece, New Zealand, Norway, Iceland and Sweden.

We all hope a second wave can be averted, but as people are enjoying  the European summer with fewer restrictions, the threat of a deeper winter pandemic is becoming more real.

Public warning systems should now be considered by all governments as an essential part of a holistic strategy of measures to tackle the virus.
