Using a very simple paperless digital technology, HAEFA medical teams in Kutupalong and Balukhali, Ukhiya Rohingya camps have been providing medical care and medicines to around 300 patients per day since October 9, 2017. In these remote places without electricity and 3G phone lines, our dedicated members of HAEFA have been using solar panels to charge the local wifi router, laptop and handheld TABs to register patients and store their medical records. Each patient is followed up longitudinally for further treatment using their digital health-card containing a picture and a scannable unique barcode. Salute to our dedicated HAEFA medical professionals who have been serving humanity in a very harsh and unhygienic condition 6 days per week!
