Deep in the Amazon rainforest in northern Brazil, where rivers are the only highways, the coronavirus pandemic is sharply limiting boat traffic, leaving villages even more cut off from the world than before.
Canoes, motor boats and ferries are the cars, trucks and buses of the Amazon, bringing people and goods to remote communities that can only be reached by river -- sometimes with a journey of more than a week.
But because of the pandemic, authorities in Amazonas state have restricted river traffic to essential travel, seeking to stop the spread of the virus in a region that could be particularly vulnerable to it.
Cargo transport is operating normally, but passenger transport is restricted to exceptional circumstances such as medical emergencies and essential services like paramedics and police, said Jerfeson Caldas, regional coordinator for national health agency Anvisa.
Even those trips are bound by special rules: boats can only operate at 40 percent of their passenger capacity, and must supply water, soap and hand sanitizer.
