When the air is smoky from burning wildfires, health experts say to stay indoors.

How long can I expect a COVID-19 illness to last? Most coronavirus patients have mild to moderate illness and recover quickly. Dr. Khalilah Gates, a Chicago lung specialist, said many of her hospitalized COVID-19 patients still have coughing episodes, breathing difficulties and fatigue three to four months after infection. She said it’s hard to predict exactly when COVID-19 patients will return to feeling well. COVID-19 can affect nearly every organ, and long-term complications can include heart inflammation, decreased kidney function, fuzzy thinking, anxiety and depression.

Public health experts say 1 million worldwide deaths are among reasons to be concerned, if not fearful, and to take everyday precautions despite rosy advice from the still-recovering president. You’re going to beat it,” Donald Trump said in a White House video released after he left the hospital Monday. But experts can’t predict which patients will develop dangerous or deadly infections. It is true, as Trump said in the video, that medicines have been found that can treat the virus, reducing chances for severe illness and death. Another reason for concern is uncertainty over which patients will develop lasting complications affecting the lungs, heart, kidneys and other organs.
