Of note: Five days of drinking tap water in New Orleans in July, and I spent five months infested with the horrid parasite giardia, which reared its head and made my life a misery on and off all autumn.
I spent almost a whole month in Brazil in January where I was exposed to a wide array of infectious and/or toxic agents, including (but not limited to)
– mosquitoes (likely laden with viruses)
– questionable plumbing infrastructure
– the occasional overflowing toilet
– coagulated cheese
– Brazilian beer
… two months later and I’m still totally fine.
