South Africa Has Affordable Ventilators, Thanks to Doctors, Engineers

South African engineers and doctors are designing makeshift, inexpensive devices to address a major challenge posed by the coronavirus – the lack of ventilators for patients.  South Africa is scrambling for thousands more ventilators as confirmed COVID-19 cases have increased to more than 7,200, with at least 138 deaths.
