It is estimated that up to 4.0 million cholera cases occur worldwide due to cholera every year. Cholera can kill within hours if untreated.3
Risk areas for Cholera
Mainly from drinking water or eating food contaminated containing the bacteria which cause cholera.1
Cholera is common in a number of countries across Africa and Asia but has also been reported in other countries where people have returned ill after travelling (see map).1,2 Outbreaks of the disease can also occur in countries where cholera was not previously common.3
Most people will not develop any symptoms, although they can still pass on the infection. Those who do develop symptoms can start to experience mild-moderate watery diarrhoea between 12 hours and 5 days after infection.3
Cholera can lead to severe watery diarrhoea and dehydration which can be fatal if not treated promptly.3 Treatment may involve oral rehydration solution, additional fluids or even antibiotics depending on the severity of illness.3
You can take the following precautions to help reduce your risk of infection:
- Visit your nearest convenient pharmacy or specialist travel health clinic for a risk assessment before your trip
- Avoid eating raw or undercooked fruit and vegetables that you haven’t prepared yourself. Use bottled or boiled water for washing food1
- Avoid eating shellfish and seafood1
- Avoid ice and ice creams1
- Use boiled or bottled water for drinking and brushing your teeth1
- Wash your hands frequently with soap and water, especially before eating and after using the toilet1
- Avoid unsanitary living conditions to reduce your risk of cholera infection4
