COVID-19 hits the lungs hardest. This is because it's a respiratory infection from the SARS-CoV-2 virus. The virus goes after the respiratory system, so people often have a cough and trouble breathing. Sometimes, it gets worse and turns into pneumonia. When that happens, the air sacs in the lungs swell up and fill with fluid. While COVID-19 can also mess with organs like the heart, kidneys, and liver, it's mainly the lungs that take the biggest hit.
