Over the past 6 years, Kinsa has deployed an network of >1M smart thermometers that has proven to accurately predict how flu is spreading. In February, we modified this tool to identify unusual spikes in fever that cannot be explained by seasonal flu — in many cases, this has been the first and only signal of COVID-19 spreading in a community. Kinsa’s early warning tool has support from public health experts, scientists, business leaders, and government officials.
A website sharing this information was launched as a public service on March 18. Our system will become more powerful as more citizens become part of the network.
