Nearly 400 municipalities have been affected by the worst natural calamity ever to hit the state of Rio Grande do Sul, with hundreds of people injured and 160,000 forced from their homes.

On Tuesday, state governor Eduardo Leite had warned the human toll was likely to rise as "the emergency is continuing to develop" in the state capital of Porto Alegre and other cities and towns. Authorities urged people not to return to affected areas due to possible landslides and health hazards.
"Contaminated water can transmit diseases," civil defense spokeswoman Sabrina Ribas warned on Wednesday.
