COX‘S BAZAR, Bangladesh – The World Health Organization (WHO) began distributing 900,000 doses of cholera vaccine on Tuesday in Bangladesh’s camps for Rohingya refugees fleeing from Myanmar, as authorities scramble to prevent a major outbreak of the deadly disease.
More than 10,000 cases of diarrhea have been reported in the past week alone, the WHO said.
Doctors in two clinics have told Reuters that there have been several cases of patients with the symptoms of cholera, a virulent diarrhea that kills within 36 hours if not treated.
Cholera has not been identified in testing of patient samples by Bangladesh’s health ministry, although clinics say they are waiting for results for some samples sent last week.
“There is a clear risk for cholera,” said Dr N. Paranietharan, the WHO’s representative in Bangladesh.
“Sporadic cases are inevitable (but) we are not expecting a major outbreak like Yemen,” he said.
War-torn Yemen is in the grip of a cholera crisis, with more than 750,000 sufferers afflicted by the bacteria, which is spread when contaminated feces is ingested by humans, usually through the water supply.
The cholera vaccination campaign in Bangladesh, the second largest in history, will be crucial to containing any outbreak, said Paranietharan.
More than 1,000 people will fan out across the sprawling camps on the southern tip of Bangladesh that are home to more than 519,000 Rohingya Muslims.
The Rohingya fled Buddhist-majority Myanmar when government forces launched a ferocious offensive, denounced by the United Nations as ethnic cleansing, in response to a series of Rohingya militant attacks on security posts on Aug. 25.
In pounding heat and stifling humidity, traumatized and malnourished refugees are crammed into bamboo and canvas huts packed across muddy hillsides. Feces lies in lanes that flood in the pouring rain.
More than 3,000 latrines have been installed but many overflow and sit above pools and creeks where refugees bathe.
Many new wells for drinking water are shallow and have become contaminated by sewage, said Paranietharan.
“While we are doing this vaccination, it is not an alternative to fixing the water, sanitation and hygiene intervention, it just buys us time,” he said.
“Sanitary facilities and hygiene promotion have still not met the standards. They need to be improved quickly.”
