Using an AI-powered Chatbot in the fight against COVID-19: GGDChat for Contact Tracing.

GGD West-Brabant innovates with Chatbot

Digitalisation and innovations were stimulated by the global pandemic. GGD West-Brabant, the municipal health service, conceptualised the chatbot during an innovation sprint. Together with they built 'GGDChat' in Conversational AI Cloud.

Discover the results of this Proof-of-Concept.

COVID-19 contact tracing

After a positive test result, the GGD starts a thorough Contact Tracing process. This consists of several parts. First, the GGD will talk to the person who was tested to get a clear picture of the situation. How is he or she doing, what are the symptoms? How was this person infected (source)? Who may have been infected by this person? Who has he/she been in contact with? Anyone who has been in the vicinity for more than 15 minutes within a 1.5-meter radius will then also receive a phone call. These persons are possibly infected and are advised to comply with the appropriate precautions. After that, monitoring will follow. All contacts are called at various moments to see how they are doing. 

An average Contact Tracing takes about 8 hours. This includes the preparation, the research, the interviews, the monitoring, the advice, and the administrative processing. 


Making it easier

At GGD West-Brabant, they believed this process of Contact Tracing and Monitoring had to become easier for the citizen. During an innovation sprint, they thought about what could help.  

The challenges: 


Scaling up was necessary to be able to call all people who tested positive. Besides the 'normal' GGD, a whole organisation was formed, focussing entirely on COVID-19. 

Customer friction 

Calling is not always the best way. Sometimes it is not the right time, or someone finds it annoying to be called. It also happened that people with complaints were actually waiting for a call from the GGD.

Beyond a questionnaire with checklist

What if people could report whether they have complaints at a self-selected time? What if we could provide contact in a way the citizen prefers?

To this end, a solution was devised: sending an automated SMS to start the conversation. However, a closed dialogue wouldn't be appropriate in this situation. GGD West-Brabant was looking for a better customer experience than just a questionnaire with a checklist would provide.

With a chatbot, the GGD can interactively retrieve information. The combination with SMS offers possibilities. This way, they can remind contacts to interact with the bot.

Integrate Conversational AI with SMS

Together with, GGD West-Brabant explored their requirements. The effortless integration between the different solutions proved to be a great advantage.

In the Proof-of-Concept, an intelligent chatbot was built using Conversational AI Cloud, which could run on the website using the Default Chatbot Interface. By integrating with the Customer Data Platform, the GGD was able to send text messages in a fully automated way.

The chatbot was used for Contact Monitoring. During quarantine, the person in question receives an SMS every day with a link to GGDchat. This is where the chatbot asks for COVID-19 symptoms. In case of any symptoms, they are immediately advised to get tested. Additionally, the chatbot can give tips to prevent further infections and knows everything about the prevailing measures.

Bart Schueler, Project Manager GGDchat at GGD West-Brabant:

"The flexibility of is outstanding. Based on our wishes, they even made adjustments to the solutions to make it work for the GGD. The privacy assessment was part of the equation from the beginning."


Easier and user-friendly

The results of the Proof-of-Concept were very promising. The project was initiated to make monitoring easier and more user-friendly, especially for citizens. We succeeded in doing so. GGD West-Brabant sent users of the conversational bot a survey. Ease of use scored very well.  

Anonymous respondent: "I absolutely loved the app, it was very clear and I didn't see any drawbacks". 


85% Time savings

One of the two best results for GGD West-Brabant was being able to trace people with symptoms. As a result, people could go for a test more quickly and then go into isolation. With the non-automated monitoring, people often waited to report their symptoms until they were called by the GGD. 

The second unique result was the time savings. By organising the monitoring this way, GGD West-Brabant saved almost 70 hours of time. This means a gain of 85%!



The response rate of 65% was higher than the target of 60%. To the daily messages, 65% responded.


An 85% time savings! An unexpected outcome, but a nice bonus. The chatbot is faster than calling.

Bart Schueler, Project Manager GGDchat at GGD West-Brabant:

"Great that wanted to make a social contribution during this pandemic. The experts really think with you during the process. They dare to break new grounds, in order to achieve the best result together."


Chatbot for public information

Due to the declining number of COVID-19 infections, GGD West-Brabant has discontinued the development and roll-out of the chatbot. Nevertheless, they do see strong potential for the future.

Conversational AI is a marvellous way of providing public information. Especially as a chatbot on your website. People can go there for all kinds of questions. For example for occupational or travel vaccinations, there are certain questions people always ask. These questions can be automated.

A chatbot could also be a godsend for STD clinics, providing information anonymously.
