Some cholera confirmed in cyclone-hit Myanmar

BANGKOK (Reuters) - Some cholera has been confirmed among survivors of Cyclone Nargis, but the number was in line with case levels in previous years in Myanmar, the World Health Organization (WHO) said on Friday.

"We do have some confirmed cholera," Maureen Birmingham, acting WHO representative in Thailand, said of the hardest-hit Irrawaddy delta where cholera is endemic.

"We don't have an explosion of cholera. Thus far the rate of cholera is no greater than the background rate that we would be seeing in Myanmar during this season," she told reporters.

A network was still being set up to monitor for diseases among 2.5 million people severely affected by the cyclone which tore through the delta two weeks ago, she said.

Diarrhoea, dysentery and skin infections have afflicted some cyclone refugees crammed into monasteries, schools and other temporary shelters after the devastating May 2 storm.

The first sign of cholera, which is spread by drinking contaminated dirty water, is "rice water" diarrhoea leading to chronic dehydration and possibly death within a few hours.

Without treatment, it can spread rapidly through populations of displaced people and kill as many as one in two victims.

The WHO has sent emergency health kits to the devastated region and was providing bleach and chlorine tablets to treat dirty water.

Corpses are still rotting along the banks of the Irrawaddy river two weeks after the disaster which killed up to 128,000, but the WHO said they pose no risk to public health.
