Fears of disease after Nepal quake

U.N. humanitarian officials in Nepal have raised alarm over the spread of disease. According to them more helicopters are needed to reach isolated mountain villages, which were hard to access.

The true extent of the damage from the magnitude-7.8 quake is still unknown as reports keep filtering in from remote areas, some of which remain entirely cut off. The U.N. has estimated the quake affected 8.1 million people — more than a quarter of Nepal’s 28 million people.
