“A few days ago we were doing laundry that included my seven year-old’s school uniform. The ViraWarn Patriot turned red, alerting us of the presence of COVID-19 in the area. We initially thought it might be an error, but decided to open all of our windows and use our Molekule air purifier (FDA approved to destroy SARS-CoV2 – https://molekule.com/technology) as a safety measure. We waited until we saw the ViraWarn Patriot turn green again.

The next morning we received an email that someone from our kid’s classroom had tested positive to COVID-19. Furthermore, we did a bit of research and found out (https://thehill.com/changing-america/well-being/medical-advances/540354-surprising-new-covid-19-study-finds-virus/) that COVID-19 can in fact remain present in clothing for a certain amount of time. The fact that we were moving the laundry just two steps away from the ViraWarn Patriot made us conclude that what we had seen was, in fact, a real alert.

We were initially shocked and then glad that our bet and investment in this new technology had paid off. We were lucky that none of us at home tested positive for COVID-19. We contribute this to the ViraWarn alert – nearly 24 hours before a reported PCR positive test – which prompted us to act to improve the air quality in our home, hence reducing the risk of getting infected.
