For a trip of 7 to 10 days floating down from Pucallpa to Iquitos to Leticia in March, is it really essential to take anti-malarials? My inclination is to avoid taking them given the side effects. I have the yellow fever vaccination. It's hard to believe everyone living in the jungle takes anti-malarials and they seem to be surviving.
I've made multiple trips to the jungle areas of southern Peru and never bothered.
I'd appreciate thoughtful, informed replies from those who know what they're talking about. Thanks.
