Designing a Public Health Mobile App

Designing for Public Health

ZikaTrack is an integrated mobile application designed to help users effectively address the challenges posed by Zika virus outbreaks.

The main goal of the app is to empower individuals by providing:

  • Access to trustworthy information
  • Real-time outbreak updates
  • Preventive guidance
  • Community engagement tools
  • Data contribution features for research purposes

This project was designed and researched from beginning to end using Figma as the primary design tool.

At its core, ZikaTrack aims to bridge the gap between public health communication and accessible digital tools.

Understanding the Problem Before Designing the Solution

“If I had an hour to solve a problem, I'd spend 55 minutes thinking about the problem and five minutes thinking about solutions.”
-Albert Einstein

This quote shaped my entire design approach.

Before designing screens or features, I needed to fully understand:

  • What is Zika?
  • Who is affected?
  • How is it transmitted?
  • What are the risks?
  • What are the prevention methods?
  • Who are the stakeholders?

Zika virus is a single-stranded RNA virus from the Flavivirus genus, primarily transmitted through Aedes aegypti mosquito bites. While 80% of infected individuals remain asymptomatic, the virus poses severe risks to pregnant women, including microcephaly and neurological complications in infants.

Understanding the medical background was essential before structuring the digital solution.

The Design Process

I began the design process for the Zika app by doing extensive research to determine the requirements of my target audience and acquire information from already-existing rival apps. I determined the most pressing issues and needed features in relation to Zika virus knowledge and prevention through user surveys and interviews with people from work friends and family.

Stakeholders and Research

Primary stakeholders include:

  • General public
  • Pregnant women
  • Medical professionals
  • Public health organizations
  • Researchers
  • Regulatory bodies

Competitive analysis revealed that while many apps provide medical information, none included photo analysis features for mosquito habitat detection, which became ZikaTrack’s unique differentiator.

Unique Features of ZikaTrack

The application includes:

  • Prevention techniques and travel advice
  • Real-time outbreak statistics
  • Interactive community messaging
  • Notification alerts
  • Photo upload and habitat analysis

The photo analysis feature allows users to upload images of potential mosquito breeding grounds. This contributes valuable environmental data for surveillance and research.

The goal was not only information delivery — but participation.

Quantitative Research Insights

A survey was conducted to understand user expectations.

Key findings:

  • 80% consider real-time updates very important
  • 80% use the internet as their primary information source
  • 100% want articles and news about Zika
  • 100% would provide anonymous data for research purposes
  • 80% are interested in community sharing features

However, 80% reported neutrality regarding satisfaction with current Zika information sources — indicating a clear opportunity for improvement.

Empathy and User-Centered Design

To design effectively, I developed an empathy map divided into:

High-Fidelity Prototypes

The final design included:

  • Onboarding with notification and location control
  • Real-time alerts screen
  • Photo upload and analysis system
  • Community interaction features
  • Clean visual hierarchy
  • Accessible UI following WCAG guidelines

Accessibility considerations included:

  • Color contrast
  • Screen reader compatibility
  • Alternative text
  • Clear navigation

The landing page reinforced the app’s friendly, community-oriented identity.

Key Takeaways

ZikaTrack is designed not only to inform but to support public health research.

Features such as photo uploads allow users to actively participate in mosquito surveillance efforts. Real-time alerts and community tools create a sense of shared responsibility.

The app balances:

  • Public health communication
  • Research data collection
  • User privacy
  • Emotional reassurance

Lessons Learned

One of the most important insights came during usability testing.

Initially, users were hesitant to provide sensitive medical data during onboarding. However, when informed that the data could contribute to vaccine research and public health initiatives, many reconsidered.

This highlighted a key principle:

Transparency builds trust.

As a result, I added:

  • Clear explanations for data collection
  • Optional consent screens
  • Skip buttons
  • Transparent communication about research use

Design helped me better understand people — their fears, hesitations, and motivations.

Technology, when ethically implemented, can become a powerful tool in medicine and disease prevention.

Conclusion

ZikaTrack demonstrates how user-centered design can address public health challenges through digital innovation.

By combining:

  • Research
  • Empathy
  • Structured UX methodology
  • Iterative testing
  • Ethical data practices

The application provides both individual empowerment and collective health contribution.

Design, in this case, becomes not only a functional solution — but a bridge between medicine and society.
