Good evening. Thanks for joining us. Tonight, america suffering its deadliest day yet in the covid19 pandemic, while looking for signs of a plateau. 1700 dead, the total number now at least 12,000. And while our doctors and nurses have been rightly lionized for their extraordinary acts of heroism, we shine a light on the other front line workers, some armed with mops, utility belts and trash bags. Their battle every bit as essential. Im going to put on my n95 mask. Every day, Latisha Knight suits up at plain view hospital in suburban new york, ready to help save lives. Now we can go in the room. Shes not here to hand out medication or perform surgery, but she is a key fighter in the war against covid19, the very epicenter of this countrys outbreak. A lot of the work you do is often unseen. We usually go in, get it done and were out. Latisha works in environmental services. Cleaning and sanitizing patients rooms. Her unit almost entirely covid19. Youre walking into a hot zone every day.
