Thanks Doc Drew. I could imagine that, even influenza had strings of zero counts, during covid. I was just looking at the UK ‘data’, that was presented in the link. Lyme disease seems to have become common. Anecdotally, I see way more feral dogs in the field than twenty years ago, and maybe ticks can adapt like feral hogs, and edge up into pheasant country. Hogs may be a tick vector that has changed the game, if there ever was one?
