Portable health clinic COVID-19 system for remote patient follow-up ensuring clinical safety

•“Test, test, test” was the global slogan from WHO for tackling the COVID-19 pandemic. Testing is very important for identifying COVID-19 positive patients and isolating them for not spreading the virus to others. Unfortunately, most of the countries, especially the developing countries, do not have enough facilities for testing. Moreover, this test is very expensive for individuals. So it is very important to identify only the suspected ones who are at high risk and send them for testing ensuring the best use of the limited valued resources. This paper suggested a COVID-19 triage protocol for identifying the suspected patients what is very important.•Studies show that about 80% of the tested positive COVID-19 patients are in mild or moderate levels and not in danger. They even don't need to be hospitalized but they can be treated being under a home quarantine state. For this purpose, this research proposes a home delivery COVID-19 healthcare service with the support of telemedicine by remote doctors using a tele-healthcare system.•As COVID-19 is a highly infectious disease, home delivery service by visiting patients at home is very risky. This study recommends a new approach of home delivery service providing COVID-19 system box with self-checking medical sensors at the patient end. The patient can check health status, share data with the remote doctor and receive tele-consultancy by using a COVID-19 application installed in a tablet PC provided in the COVID-19 system box. This ensures the clinical safety of both the patients and health workers.•The result shows the high accuracy of the triage system in identifying COVID-19 suspects. Thus, this system can detect the right people to go under investigation and avoid the unnecessary crowds in the test centers what is very important to tackle the pandemic with limited resources of the developing world. A developing country like Bangladesh suffers very much from the sudden appearance of the COVID-19 pandemic due to the shortage of medical facilities for testing and follow-up treatment. The Portable Health Clinic (PHC) system has developed the COVID-19 module with a triage system for the detection of COVID-19 suspects and the follow-up of the home quarantined COVID-19 patients to reduce the workload of the limited medical facilities. The PHC COVID-19 system maintains a questionnaire-based triage function using the experience of the Japanese practice of diseases management for early detection of suspected COVID-
