Haiti could soon face an outbreak of diseases due to the lack of enough shelter and bathroom facilities.

In a camp just across the street from Haiti's collapsed National Palace, one toilet served approximately 2,000 people. It forced many to use a gutter that runs parallel to an area where food is prepared and children are bathed.

"We wash the vegetables first from water brought in by trucks, but a lot of times the water isn't clean," said one 45-year-old Haitian mother. "We don't have any choice."

Many crowded areas have puddles of filthy water, which have become a breeding ground for mosquitoes.

That, in turn, has begun the spread of deadly diseases and epidemics such as dengue, malaria and cholera.

Some hospitals are reporting that half the children they treat already have malaria.
