COVID-19 affects many parts of the body. People could experience some or all of these symptoms.

Like most viruses, SARS-CoV-2 is so tiny that one thousand viruses would have to line up to equal the width of a human hair. Yet once the virus enters the body through the eyes, nose, or mouth, it can take over many organs. First, the virus attacks cells in the nose, reproducing and spreading down the airway to the lungs. People may notice a cough, a fever, headache, or a sore throat. Flu and colds typically infect only the upper airway, but SARS-CoV-2 infects the entire respiratory system, from the nose to the millions of tiny air sacs in the lungs called alveoli. The alveoli exchange the oxygen you inhale for the carbon dioxide you exhale, ensuring your body has all the oxygen it needs. This explains why shortness of breath and a feeling of not getting enough air are early signs of COVID-19. In severe cases, dead cells and fluid fill the lungs. The damage can be so bad that a few people have required lung transplants to survive.

SARS-CoV-2 frequently attacks the kidneys. Early in the pandemic, doctors were startled to find that for every ten COVID-19 patients who were sick enough to be in intensive care units, as many as three had lost kidney function. They required dialysis, which cleans the blood when the kidneys cannot. Dr. Alan Kliger, a kidney specialist at Yale University School of Medicine, said, “That’s a huge number of people who have this problem. That’s new to me. I think it’s very possible that the virus attaches to the kidney cells and attacks them.”
