Since COVID days I’ve always carried hand sanitizer and a packet of those wet-wipe tissues (unscented of course!)
A small bottle or tube of gel alcohol hand sanitizer is useful.
I started using this a few years before Covid while on field contracts with a colleague who had contracted Lyme disease.
He made a point of using it before eating picnics or handling drinking water, he said he didn't want to catch anything else.
We got the firm we worked for to add gel alcohol to the field kit they already provided for their employees, along with the first aid kit and (IMO useless) snake venom extractor.
Hand sanitizer is no good for Lyme disease, as that is transmitted by tick bites. But it can help protect from many other nasty pathogens, such as leptospirose, which can be transmitted in water contaminated by infected rodents such as rats and coypu.
