The eHAC is designed by the Indonesian Ministry of Health and is designed to keep track of possible CO VID-19 acute cases moving into and across the nation. It is also useful for healthcare workers who work in areas with high risk of contracting measles, influenza, or any other type of chronic viral respiratory infection. These include the Philippines, Sumatra, and Borneo.
