Always getting sick after 1.18 update

[Mongo63a 1]

For some reason I keep getting cholera and I have no idea how its happening. I am using a canteen and 1 water bottle. I either use well water from the towns or if from a lake I use chlorine tabs to purify it. I have gloves so there is no issue with bloody hands.  I was able to cure it and while running around and only drinking from a well in a town I got it again. I have been cooking wolf steaks with a frying pan over a gas stove.

 

Do you need to get rid of all your water containers after you get cholera and cure it? Before 1.18 I never had this issue so I have no idea what is happening.

Same, 
I drank a found water bottle and it gave me cholera. which is understandable. but I've used vitamins to lose the icon and symptoms ( no more vomiting or sweats.) Cholera returned after some time, the second round I ditched my mask and didn't eat or drink anything, the virus left and again returned with no cause. I'm on round 3 cured (for now) and hoping I'm not bugged.
