There is a strong evidence to show that cholera disease is correlated with environment variables, as low precipitation and high temperatures in warmer months could provide the swifter bacterial replication. These conditions in Iran, especially in the central parts, may raise the cholera infection rates.

How is cholera related to climate change?

By midcentury, outbreaks of cholera may worsen and move inland as climate change continues. Researchers studying disease already agree that as temperatures warm and the climate becomes more unpredictable, populations around the world will most likely see more and more cholera outbreaks.

When does cholera become endemic in an area?

Epidemiology, risk factors, and disease burden. Cholera can be endemic or epidemic. A cholera-endemic area is an area where confirmed cholera cases were detected during the last 3 years with evidence of local transmission (meaning the cases are not imported from elsewhere).

Is there a global strategy to end cholera?

A global strategy on cholera control, Ending Cholera: a global roadmap to 2030, with a target to reduce cholera deaths by 90% was launched in 2017. Cholera is an acute diarrhoeal infection caused by ingestion of food or water contaminated with the bacterium Vibrio cholerae.

What are the signs and symptoms of cholera?

Illness & Symptoms. Persons with severe cholera can develop acute renal failure, severe electrolyte imbalances and coma. If untreated, severe dehydration can rapidly lead to shock and death in hours.
