We have underestimated and misunderstood COVID-19 since it first appeared. And as we learn more, it’s clear that COVID-19 can be more than just a respiratory disease. It’s joined the ranks of other “great imitators”—diseases that can look like almost any condition.

It can be a gastrointestinal disease causing only diarrhea and abdominal pain. It can cause symptoms that may be confused with a cold or the flu. It can cause pinkeye, a runny nose, loss of taste and smell, muscle aches, fatigue, diarrhea, loss of appetite, nausea and vomiting, whole-body rashes, and areas of swelling and redness in just a few spots.

In a more severe disease, doctors have also reported people having heart rhythm problems, heart failure, kidney damage, confusion, headaches, seizures, brain inflammation, Guillain-Barre syndrome, and fainting spells, along with new sugar control problems, blood clots throughout the body, and severe immune system responses.
