Tens of thousands of students in southern Brazil have been gone a month without seeing their classrooms after catastrophic floods submerged some schools and turned others into shelters, raising concerns about their mental health. Of Rio Grande do Sul state's more than 2,000 public schools, nearly a fifth remain closed, affecting some 185,000 students. Rains that started in late April have swollen several rivers and lakes in Brazil's southernmost state of Rio Grande do Sul to record highs, causing floods that killed at least 169 people and left more than 580,000 displaced, according to state officials.
