Cholera The Forgotten Disease
Cholera the Forgotten Disease It seems every time we hear of a major flood or
earthquake in a developing country, we hear once again about cholera. Cholera
has been very rare in industrial nations, such as the USA, for the last 100
years, however, what we do not realize is that cholera is endemic in many small
countries which have limited drinking water and sewage treatment facilities.
Caused by an infection of bacterium Vibrio Cholerae in the intestine, a cholera
infection is often mild or without symptoms, but sometimes is severe. Symptoms
appear 2 to 3 days after initial exposure. Approximately one in 20 infected
persons display symptoms of water diarrhea, vomiting, and leg cramps; this rapid
lose of body fluids leads to dehydration and sometimes shock. These fluids must
be replaced either intravenously or by drinking liquids such as fruit juice,
soup, or fluids called oral rehydration salts, which replace electrolytes.
Antibiotics may be proscribed to shorten the duration of diarrhea and excretion
of bacteria in feces. Without treatment, death may occur in hours. Although
cholera can be life-threating, it can easily be prevented and treated. A vaccine
for cholera is available; however, it confers only brief, 2 to 6 months, and
incomplete immunity, only about 50% effective. It is not recommended. Since
cholera is still common in other parts of the world, everyone, especially
travelers, should be aware of how the disease is transmitted and what can be
done to prevent it. The disease is not likely to spread directly from one person
to another; therefore, casual contact with an infected person is not a risk for
becoming ill.
A person may get cholera by drinking water or eating food
contaminated with the Vibrio cholerae bacterium. In an epidemic, the source of
the contamination is usually the feces of an infected person entering the main
water source. The cholera bacterium may also live in brackish rivers and coastal
waters. Shellfish from infected waters can cause infection. Unwashed fresh
fruits and vegetables irrigated with tainted water can also infect. Prevention
of cholera is easy. When in a possibly infected area: cook the food properly,
eat foods promptly after their preparation including shellfish, fruits and
vegetables, avoid drinking untreated water, and wash your hands thoroughly with
soap often. Cholera will not have great impact on me as a surgical technologist.
It is not common in the United States, and since it is not transmitted directly
from person to person, there is no risk of the Operating room staff transmitting
the disease from the patient. If an ill patient is scheduled, elective surgery
will be postponed, and in the case of emergency surgery on someone with cholera,
their fluids will be monitored meticulously. In closing, cholera, although not
prevalent, is a threat to world travelers. Education of the causes, treatment,
and prevention are a traveler’s first line of defense
