As hospitals seek innovative solutions to treat the surge of COVID-19 patients with resources running thin, expanding ventilator supply has been central to the conversation. Research has shown that only a third of patients placed on a ventilator survive the experience. Now, some experts are wondering if ventilators could be contributing to the poor survival rate and whether ventilators are being overused. (Anoruo, 4/21)

They confront death daily, but the young doctors rarely pondered their own mortality until the coronavirus pandemic, when clinicians like them started dying. During an overnight lull last month, five Massachusetts General Hospital residents in their 20s and 30s recorded their health care proxies, naming who would make medical decisions for them if they became too sick to.

With some states getting ready to lift their stay-at-home orders and relax their social distancing measures, it may seem that health officials have the coronavirus outbreak under control. But researchers say there’s still much they don’t know about the virus — and the answers to their questions could help determine when it will be safe for life to return to normal. The mysteries scientists are most eager to solve have shifted somewhat since this coronavirus began sickening people in Wuhan, China, in late 2019. (Khan, 4/21)

With a vaccine still months or years away, and no magic drug or miracle cure for the coronavirus, the cruel realities of this virus can hit families incredibly quickly. But with the scientific world working around the clock on potential lifesaving breakthroughs, there is hope. (Schlosberg and Hartung, 4/21)
