Ruma-H is a remote monitoring system designed to manage infectious diseases such as dengue, COVID-19, and tuberculosis. It enables continuous monitoring of important clinical parameters such as heart rate (HR), oxygen level (SpO2), and body temperature, along with symptom assessment, to identify patients at risk of health deterioration. This early identification allows for timely medical intervention and reduces hospital visits or admissions thus facilitating healthcare. Real-time data provided by Ruma-H is accessible to healthcare professionals and supports fast and effective decision-making. By improving patient outcomes and reducing pressure on the health care system, Ruma-H also contributes to health system improvement and response to pandemics, offering scalable and efficient tools to manage infectious diseases in populations.
