This is what the coronavirus could do to your body
Photo: Dr. F.A. Murphy/Getty Images/Visuals Unlimited You call a friend and arrange to meet for lunch. It’s unseasonably springlike, so you choose a place with outdoor seating, which seems like it should be safer. As usual, you take all reasonable precautions: You use hand sanitizer, sit a good distance from other customers, and try to avoid touching your face, though that last part is hard. A part of you suspects that this whole thing might be overblown.
As the virus drifts through the lung’s mucus, it bumps into one of the cells that line the surface. The cell is considerably larger than the virus; on the football-field scale, it’s 26 feet across. A billion years of evolution have equipped it to resist attackers. But it also has a vulnerability — a backdoor. Protruding from its surface is a chunk of protein called angiotensin converting enzyme 2, or ACE2 receptor.
As they are churned out, these components are transferred on a kind of cellular conveyor belt toward the surface of the cell. The virus membrane and spike proteins wrap around RNA strands, and a new particle is ready. These collect in internal bubbles, called vesicles, that move to the surface, burst open, and release new virus particles into your body by the tens and hundreds of thousands.
You call up an ex, and she agrees to meet you for a walk along the river. You’re hoping that the end-of-the-world zeitgeist might kindle some afternoon recklessness, but the face mask she’s wearing kills the vibe. Also she tells you that she’s decided to move in with a guy she met at Landmark. You didn’t even know she was into Landmark. She gives you a warm hug as you say good-bye, and you tell her it was great to see her, but you leave feeling deflated.
After four days of raging fever and feeling sore all over, you realize that you’re sicker than you’ve ever been in your life. You’ve got a dry cough that shakes you so hard that your back hurts. Fighting for breath, you order an Uber and head to the nearest emergency room.
