Cholera: Treatment is simple, just not in Zimbabwe
The breakdown of the country's healthcare infrastructure is
behind the large number of deaths.

The cholera outbreak that has killed at least 775 people in Zimbabwe
is part of an epidemic that has been afflicting Africa for three
decades, according to the U.S. Centers for Disease Control and
The disease is the result of a lack of adequate sanitation and water
treatment facilities; the high number of deaths results from the
near-total breakdown of the healthcare infrastructure in Zimbabwe.
Cholera is an acute diarrheal illness caused by infection by the
bacterium Vibrio cholerae.The organism spreads when infected feces
enter the water supply and the bacteria are not killed or removed by
treatment. Cholera is no longer a problem in industrialized countries,
except for the occasional case brought by returning travelers or
caused by consumption of inadequately cooked shellfish.
In most people, the infection is mild with few or no symptoms. But
about one in 20 victims is stricken with profuse, watery diarrhea,
vomiting and leg cramps. That can lead to severe dehydration, shock
The profuse diarrhea contaminates water supplies if the feces enters
latrines or directly enters rivers and streams, causing the disease to
Treatment is simple: rehydration with an oral solution made from a
prepackaged mixture of sugar and salts. The most severe cases may
require intravenous fluid replacement. Treatment must be started
within a couple of hours after symptoms develop, however, and
Zimbabwe's lack of health infrastructure makes that difficult.
Antibiotics such as tetracycline can shorten the course of the illness
but generally are not necessary if rehydration is adequate.
A new oral vaccine called Dukoral, manufactured by the Swedish company
SBL Vaccin, is available in some countries. The CDC says it appears to
provide better protection and has fewer side effects than previous
vaccines, but the agency does not recommend it for travelers.
