An Unwelcome Visitor from the Past


A young man at the Chateau Marmont had been coughing for two weeks. He had a fever, and my stethoscope revealed lung noises typical of pneumonia.

I enjoy diagnosing pneumonia because, in an otherwise healthy person, it’s the only common illness with a cough that doctors can cure. Everything else is a virus. 

I didn’t like this particular diagnosis. It takes a tough germ to cause pneumonia in most people, so unpleasant symptoms begin quickly. This man’s cough had persisted for some time. Furthermore, he was gay and admitted to having unprotected sex. I suspected that he had a pneumocystis infection. Pneumocystis is a fungus so benign that it lives in the lungs of most of us, causing no trouble.

Until forty years ago, it was rare, affecting patients already sick with cancer or serious diseases requiring drugs that suppressed immunity. Doctors were mystified when Pneumocystis began attacking previously healthy young men during the 1980s. It turned out to be the most common sign of AIDS.

It’s rare again today because we track immune cells of HIV patients and prescribe preventive drugs when the numbers drop. This young man had not been tested, but he was no fool. He cut short his visit and returned home.
