A few months after I was born, I developed a cough and a low fever. My parents brought me to a pediatrician, who told them it was just a cold and not to worry. Unbeknownst to that doctor, I had contracted respiratory syncytial virus (RSV). RSV is a common virus that infects many newborns without much issue, but in about half a percent of cases, it leads to life-threatening pneumonia and bronchitis. Less than a day after that doctor visit, my face was pale, my breathing was shallow and my fever was well over 101 degrees. By the time my mother arrived at the emergency department, my breathing was a faint, whining wheeze. As she carried me inside, my respiration was so severely inhibited that my chest was collapsing—rather than inflating—every time I drew a breath. I was in such dire condition that, immediately after she ran through the doors, a nurse ripped me from my mother’s arms and started emergency CPR.
