Aid arrives, desperation spreads in cutoff towns

Concern is growing over an increase in cholera cases after Hurricane Matthew

Helicopters are ferrying in food and medicine to devastated southwestern Haiti, but almost a week after Hurricane Matthew's assault life here is still far from normal and desperation is growing in communities where aid has yet to arrive.

Power is still out, water and food are scarce, and officials say that young men in villages along the road between the hard-hit cities of Les Cayes and Jeremie are putting up blockades of rocks and broken branches to halt convoys of vehicles bringing relief supplies.
