Cholera is an acute diarrhoeal disease that can kill within hours if left untreated.Cholera is a disease of poverty affecting people with inadequate access to safe water and basic sanitation.Conflict, unplanned urbanization and climate change all increase the risk of cholera.Researchers have estimated that each year there are 1.3 to 4.0 million cases of cholera, and 21 000 to 143 000 deaths worldwide due to cholera (1).Cholera is an acute diarrhoeal infection caused by ingestion of food or water contaminated with the bacterium Vibrio cholerae. Cholera remains a global threat to public health and an indicator of inequity and lack of social development.
Cholera is an extremely virulent disease transmitted through the ingestion of contaminated food or water (2). Cholera can cause severe acute watery diarrhoea and the severe forms of the disease can kill within hours if left untreated. Most people infected with V. cholerae do not develop any symptoms, although the bacteria are present in their faece...
During the 19th century, cholera spread across the world from its original reservoir in the Ganges delta in India. Six subsequent pandemics killed millions of people across all continents. The current (seventh) pandemic started in South Asia in 1961, reached Africa in 1971 and the Americas in 1991. Cholera is now endemic in many countries.
There are many serogroups of V. cholerae, but only two – O1 and O139 – cause outbreaks. V. cholerae O1 has caused all recent outbreaks. V. choleraeO139 – first identified in Bangladesh in 1992 – caused outbreaks in the past, but recently has only been identified in sporadic cases. It has never been identified outside Asia. There is no difference in...
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). A cholera outbreak/epidemic can occur in both endemic countries and in countries where cholera does not regularly occur. Ch...
A multifaceted approach is key to control cholera, and to reduce deaths. A combination of surveillance, water, sanitation and hygiene, social mobilization, treatment, and oral cholera vaccines are used.
Cholera surveillance should be part of an integrated disease surveillance system that includes feedback at the local level and information-sharing at the global level. The detection of a suspected cholera case is based on clinical suspicion in patients aged two years and older with acute watery diarrhoea and severe dehydration or dying from acute w...
The long-term solution for cholera control lies in economic development and universal access to safe drinking water and basic sanitation. Actions targeting environmental conditions include the implementation of adapted long-term sustainable WASH solutions to ensure use of safe water and basic sanitation and good hygiene practices. In addition to ch...
Cholera is an easily treatable disease. The majority of people can be treated successfully through prompt administration of oral rehydration solution (ORS). The WHO/UNICEF ORS standard sachet is dissolved in 1 litre (L) of clean water. Adult patients may require up to 6 L of ORS to treat moderate dehydration on the first day. Severely dehydrated pa...
Dec 9, 2022 · Causes. Risk factors. Complications. Prevention. Overview. Cholera is a bacterial disease usually spread through contaminated water. Cholera causes severe diarrhea and dehydration. Left untreated, cholera can be fatal within hours, even in previously healthy people.
Apr 30, 2021 · When a person eats or drinks food or water that contains V. cholerae, the bacteria grow inside them. The bacteria then make the small intestines secrete (leak) fluid, leading to diarrhea. Cholera usually doesn’t spread directly from person to person, but it can.
Drinking any contaminated water and eating any foods washed in the water, as well as shellfish living in the affected waterway, can cause a person to contract an infection. Cholera is rarely spread directly from person to person.
