Even to day also cholera kills about 60,000 to 120,000 people annually. Mostly the children. Cholera vaccine is not very effective. So cholera is going to be threat for ever. It is one of the biological weapon, which can be used in wars, to kill the 'Humanity'.
Cholera, typhoid, smallpox and syphilis
The threat of cholera was eliminated from US and for that purpose from all the developed countries, by way of good sanitation and hygiene. The human longevity has increased to present level, long before (almost 100 years) the advent of modern chemotherapy.
Cholera is still common in developing countries. It is common to get the patients of cholera like syndrome in your clinical practice and at times of severe case of cholera. The picture has changed on positive side over last three decades, due to improved sanitation and public awareness of water born diseases.
cholera affects the countries which have poverty & cannot afford clean water. ie India Brazil and Peru.
The terrorist threat still exists.
Cholera is caused by the bacteria called as vibrio cholerae. These bacteria are excreted in very large number in loose motion of the cholera patient. These bacteria are transmitted through contaminated water and by flies, at times by hands to other people.
Cholera is spread by sewage-tainted drinking water. Cholera can become a problem anyplace that basic sanitary services cannot be provided. Disaster zones, war zones, wilderness areas; anything that interrupts the handling of sewage and the supply of clean drinking water can spread cholera.

I believe it is because there still is no cure to either disease.
cholera is poopy.
In cholera vaccination you are injected the dead cells of cholera. So you get antibodies to cholera. This vaccine is not very effective. The protection rate is some where 50 to 60 % only. So you can not keep faith on the vaccine for protection from cholera.
Chlorine does not cause cholera. You may get cholera, by absence of that little chlorine in public water supply.
