Katrina: Aftermath is a public health nightmare

Infection Control Monitor, October 4, 2005

West Nile virus, typhoid, cholera, and hepatitis may be the latest challenges facing the victims of Hurricane Katrina, health experts say.

Flooding since the hurricane on Aug. 29 has contaminated water supplies, which could lead to typhoid, cholera, and hepatitis. The flooding also may serve as a breeding ground for mosquitoes, which may spread West Nile virus.

About 80% of New Orleans is flooded, according to the Centers for Disease Control and Prevention.

"We are gravely concerned about the potential for cholera, typhoid, and dehydrating diseases that could come as a result of the stagnant water and the conditions," Health and Human Services Secretary Michael Leavitt said at a recent briefing.

The hurricane has left behind decomposing bodies, failed sewage, and rotting debris, which are all potential breeding grounds for bacteria, viruses, and parasites.

Health officials are trying to get safe drinking water into the region. They are also trying to encourage residents to leave the area until the contaminated water is displaced.
