Diseases & National Health Programme
For controlling an outbreak of cholera, all of the following measures are recommended except
|B||Proper disposal of excreta|
|C||Chlorination of water|
|D||Early detection and management of cases|
a. Mass chemoprophylaxis is not advised for total community because in order to prevent 1 serious case of cholera, about 10,000 persons must be given the drug.
b. The drug's affect is short lived for a few days and whenever mass chemoprophylaxis was attempted, it failed to stop the spread of cholera.
c. Due to these reasons, chemoprophylaxis is advised only for household contacts or of a closed community in which cholera has occurred. Tetracycline is the drug of choice for chemoprophylaxis.
