How COVID-19 Affects Your Body
What COVID-19 Can Do
Doctors continue to learn about the short-term and long-term effects of COVID-19 on your body. For some people, It starts with basic flu symptoms. But it could eventually affect your lungs, liver, kidneys, and even your brain.
How It Spreads
Usually the virus makes contact with you when a nearby infected person sends droplets(微滴) into the air by coughing, sneezing, or talking. It spreads easily between people within about 6 feet of each other. An infected person can spread these droplets, even if they don’t feel sick. The virus may infect you after you touch an object, like a doorknob(门把手), that has the virus on it. But that's not as common.
Main Symptoms —Upper Respiratory Infection（上呼吸道感染）
Once the virus enters the body, it usually settles in the cells that line your nose, sinus cavity(鼻窦腔), and throat. For most people, this is where it stays. Symptoms often follow, but you may not feel anything for up to 2 weeks, as the virus starts to invade(侵略) healthy cells and reproduce. You can transmit (传播) it to others even if you don't show any symptoms.
Other Common Symptoms
The first symptoms that typically appear include a fever, headache, sore throat, and dry cough. But what you'll feel can vary widely in this early stage. You may also have:
●Shortness of breath
●Chills, fever, body aches
●Loss of sense of smell or taste
●Unusual tiredness
●Stuffy(不通的) or runny nose
●Nausea or diarrhea
No Symptoms?
Some studies show that up to 40% of people with COVID-19 are “asymptomatic(无症状的).” That means they don’t feel sick or have symptoms. But the virus can still affect your body. X-rays and CT scans of some people without symptoms show lung damage including “ground-glass opacities,”a typical lung lesion(损害) in people with COVID-19.
