Beware And Take Care Symptoms, Treatment And Prevention Of Cholera

SHARE

Health cabinet secretary Cleopa Mailu, on tuesday announced that 79 kenyans in critical condition were in Nairobi hospitals suffering from cholera.

More recently, a groom-to-be died of Cholera after eating contaminated samosas at Kenya International Confrence Centre.

To avoid such cases, read through these symptoms, treatment and prevention of cholera.

How cholera is spread

Infection occurs when the bacteria are taken in by mouth, usually in food or water contaminated by human faeces.

Cholera is spread by:

  • drinking contaminated water
  • eating food contaminated by dirty water, soiled hands or flies
  • eating fish or shellfish from contaminated waters.

The cholera organism can survive for long periods in water and ice.

Signs and symptoms

Infection is often mild, or without any symptoms, but it can be severe.

Symptoms include:

  • sudden onset of painless, profuse, watery diarrhoea
  • nausea and vomiting early in the illness
  • dehydration.

In severe untreated cases, death may occur within hours, but with simple treatment full recovery can be expected.

Diagnosis

Diagnosis is suspected on clinical signs and confirmed by growing Vibrio cholerae from a faecal specimen.

Incubation period

(time between becoming infected and developing symptoms)

A few hours to 5 days, usually 2 to 3 days.

Infectious period

(time during which an infected person can infect others)

During the acute stage and for a few days after recovery. However, some people (called ‘carriers’) who do not have symptoms may still carry the bacteria and be infectious, sometimes for months to years.

Treatment

Anyone who has been in a high-risk region within the previous 5 days and develops severe vomiting and diarrhoea should seek urgent medical assessment.

Although cholera can be life-threatening, it is easily treated by immediate rehydration, that is, replacement of the fluid and salts lost through diarrhoea.

Oral rehydration fluid is recommended. This can be obtained from pharmacies.

Patients with severe dehydration or who are unable to keep oral fluids down require hospitalisation and intravenous fluid replacement.

Antibiotics shorten the duration of the illness and lessen the severity, but they are not as important as rehydration.

Prevention

  • Exclude people with cholera from childcare, preschool, school and work until there has been no diarrhoea for 24 hours. If working as a food handler in a food business, the exclusion period should be until there has been no diarrhoea or vomiting for 48 hours.
  • Infants, children and adults with cholera infection should not swim until there has been no diarrhoea for 24 hours.
  • Follow good hand washing procedures.
  • Severely ill patients should be isolated in hospital.
  • People who are less severely ill can be nursed at home. Faeces and vomit can be disposed of into the toilet except in areas where there is not an adequate sewage disposal system.
  • All linen and articles used by the patient should be washed in hot soapy water and the room thoroughly cleaned when the person has recovered.
  • Vaccines are available but are recommended only for travellers to high-risk countries. They may not protect against all strains of cholera bacteria and protection is for several months only.
  • When travelling to high-risk countries, seek advice from a travel medical clinic or an experienced general practitioner on how to protect yourself from cholera and other diarrhoeal illnesses. In particular, drink only water that has been boiled or disinfected with iodine or chlorine tablets. Carbonated bottled drinks are usually safe, if no ice is added.
  • Good food handling procedures should always be followed, including when travelling.
  • Contacts (for example, family members) of a case should be observed for 5 days from the date of the last exposure to the infected person. A contact is any person who has been close enough to an infected person to be at risk of having acquired the infection from that person.
