It was not until 2010 that I read about the "Punta Gorda Flu" in Florida. It seemed hard to believe this had been overlooked since 1956. I went to the trouble of getting
the NEJM paper on this investigation, by Henderson and Poskanzer. Henderson was a known quantity with an excellent reputation in epidemiology, but the CDC seemed to have lost any recollection of him. Poskanzer was a respected neurologist who went on to investigate clusters of MS in places like the Orkney Islands.
Poskanzer et al. also proposed a "two-hit" model of a number of neurological diseases.
Who did the extensive library research to connect present illness with past reports -- at a time when you couldn't just search the Internet? Dr. Lerner.
Who made serious attempts to treat the illness with antivirals at a time when this was professionally dangerous? Dr. Lerner.
He was the one who insisted treatment had to last longer than a few weeks. He also emphasized there was frequently onset of chronic illness following an acute viral illness. This model is now being used in a number of research studies. He was decades ahead of the official medical establishment.
Personal confession: I just happened to pass through Punta Gorda in 1956, and stayed in a tourist destination nearby where people from Punta Gorda held service jobs. I wasn't too sick at the time, but when the Asian Flu hit in 1957 I was so sick I was afraid I was going to live. This is my basis for believing in a "two-hit" model.
You can find psychiatric research by Karl Menninger on the increase in psychiatric illnesses after the "Spanish Flu" epidemic of 1918, and on the surprising recovery some individuals made years later without any currently accepted treatments. I haven't seen corresponding research on the consequences of the Asian Flu epidemic of 1957. It seems most doctors of that time "knew" psychiatric diseases were not caused by viruses, and that psychiatric diagnoses were infallible.
Dr. Lerner was an important exception. We will all miss him.
