During COVID-19 pandemic, the disease could spread rapidly. It is crucial that we have early detection. There are many technologies that would enhance COVID-19 surveillance and response. One technology that I would like to share is the technology that aggregated data worldwide to provide epidemiology insights, such as HealthMap first developed at Boston Children’s Hospital in 2006. HealthMap collects data from public sources to visualize a simple and easy-to-use map. The map can be used for disease outbreak monitoring and real-time surveillance of COVID-19 diseases. In addition, HealthMap shares the available dataset publicly to be used for further analysis of outbreak and preparation. Real-time surveillance supports rapid action taken to control the disease. Rather than COVID-19 disease, HealthMap also has other disease data such as Flu, Ebola, etc. For more information, please see https://healthmap.org/about/. Thank you.
