According to

  • Cholera has undergone mutations, causing more deaths
  • Outbreaks now last longer, mass vaccinations needed
  • Experts differ on utility of vaccines

The first mutation resulted in the bacterium infecting patients thought to be immune because of previous exposure to an older strain. The second made it more dangerous.

With the new cholera strain posing a greater threat, lasting longer and with the availability of improved vaccines, the time has come for a rethink, of past expert views on the appropriateness of vacinnating people against cholera.
