Things You Need To Know About Cholera
What is Cholera?
What Causes Cholera?
Cholera is an extremely virulent disease. It affects both children and adults and can kill within hours. Cholera transmission is closely linked to inadequate environmental management. Typical at-risk areas include peri-urban slums, where basic infrastructure is not available, as well as camps for internally displaced people or refugees, where minimum requirements of clean water and sanitation are not met. Underdeveloped countries such as Africa are at a higher risk than most. Any disruption of water and sanitation systems, or the displacement of populations to inadequate and overcrowded camps can increase the risk of cholera transmission if the bacteria is present or introduced. For 2011 alone, a total of 589 854 cases were notified from 58 countries, including 7816 deaths. Many more cases were unaccounted for due to limitations in surveillance systems and fear of trade and travel sanctions. The true burden of the disease is estimated to be 3–5 million cases and 100 000–120 000 deaths annually.
Check Your Stool; Symptoms of Cholera
Cholera is an easily treatable disease. Up to 80% of people can be treated successfully through the administration of oral rehydration salts. Very severely dehydrated patients require administration of IV fluids. Such patients also require appropriate antibiotics to diminish the duration of diarrhea, reduce the volume of rehydration fluids needed, and shorten the duration of V. cholerae excretion. Mass administration of antibiotics is not recommended, as it has no effect on the spread of cholera and contributes to increasing antimicrobial resistance. In order to ensure timely access to treatment, cholera treatment centers (CTCs) should be set up among the affected populations. With proper treatment, the case fatality rate should remain below 1%.
Once an outbreak is detected, the usual intervention strategy is to reduce deaths by ensuring prompt access to treatment, and to control the spread of the disease by providing safe water, proper sanitation and health education for improved hygiene and safe food handling practices by the community. The provision of safe water and sanitation is a challenge but remains the critical factor, and one of the only ways to really reduce and prevent the impact of cholera.
