You will hear repeatedly that there are no mosquitoes on the Negra River. This may be true on the river itself, but once you get into the forest or near people there are mosquitoes. Perhaps not enough to drive you crazy, but enough to transmit Malaria. I took Chloroquin but still came down with Malaria two weeks after exposure. This fits the expected course of the disease and emphasizes the fact that the prophylaxis may be protective, but it is not 100% effective. My home town doctors seemed to enjoy the break from the usual things they have to treat for treatment of the exotic.
When you're four nights in a boat down the Amazon, you either:
- don't eat
- took your own food
- eat what they give you
I chose number 3 and used the bathroom 10 times a day for the next three or four days upon docking.
So try not to eat the food served on board, if you have a stomach used to fresh food bewared on fridges.
Alternative: buy some cheese from people on some intermediate harbours in the middle of the Amazon! Or some shrimps.
Just don't eat that lousy chicken!!
First of all, because of the rainforest, humidity and weather changes viruses and flus spread fast and often.
A flu shot can help you, it really sux to get a cold or a flu on vacations.
Also, take care with the mosquitos and insect bites if you are going to Presidente Figueiredo or in the country side or one of those river beaches in the middle of the river.
And for those who enjoy getting in touch with nature, DO NOT GO SWIMMING NAKED.
Some fish can swim up any available cavity, like the Candiru, for instance.
Also, avoid swimming if you have bleeding wounds too. No biggy, just common sense.
And remember only "Mad dogs and Englishmen go out in the midday sun".
If you plan on walking around downtown in a sunny day, try not to do it in the middle of the day. Too hot and no wind at all. If you are not used to the hot weather you might feel sick.
Wear light clothes!
