> That’s why we have so few pandemics!! Depends on how you define pandemic. Just in my lifetime I've seen the rise of HIV, SARS-CoV, MERS-CoV, H1N1, SARS-CoV-2, and perhaps others that I've forgotten, that meet the dictionary definition of pandemic. That is more than one pandemic per decade, on average, which seems like a lot. But you can also avoid calling them pandemics. HIV, for example, is officially a "worldwide epidemic". As per the dictionary definition of pandemic, I cannot find any difference between pandemic and worldwide epidemic, but I suppose to an epidemiologist there is a difference.
