Our vision is a world without disease outbreaks. At City Health Tech we believe that technology is the means to prevent the spread of diseases in cities and other vulnerable communities. 95% of people wash their hands improperly which has drastic effects given that 80% of preventable diseases are spread through contact with surfaces and each other. Preventable disease has an impact on every facet of life: There were 1 billion cases of the common cold last year resulting in $100B+ lost in US GDP due to preventable illness, 48 million Americans will suffer from food borne illness annually, and over 1 million K-12 school days are missed every day. Our device, OPAL, is our first step to standardize community health education, promote healthy handwashing habits, and collect data to provide valuable insights to help communities live healthier. We are building the future of handwashing. Through user centered design, first class technology, and community engagement, we are committed to promoting disease prevention in cities around the world.
