CAIRO, January 7 (IslamOnline.net & News Agencies) - Sleeping in open-air slimy camps and using greenish water for cooking, cleaning and drinking, survivors of Asia’s devastating natural disaster are facing high risks of killer diseases, threatening more residents, especially children, with death.

Surviving the killer tidal waves that pounded her country, thin and frail seven-month-old baby, Fatima, found herself threatened by another killer disease, has been suffering from diarrhea, British daily The Guardian reported Friday, January 7, as a case in point.

Wailing in the arms of her grandmother, Fatima has been losing weight after being attacked with killer diseases.

“Since the illness came, she is getting thinner. I do not know what to do,” Meera, Fatima' mother, told the daily.

It was simple to guess reasons why Fatima, and other children, were unable to recover. The tsunami survivors, in Sri Lanka, are living in slimy camps and using greenish water for cooking, cleaning and drinking, according to the daily.

“All the water here has been contaminated. How can she get better staying in a place like this?” Kalandhar Rais, a public health doctor in Kalmunai, told the paper.

“We need proper chlorination facilities and hand pumps from international organizations. Until then we are simply spreading disease and will face another disaster.”

In the Sri Lankan district of Ampara, physicians said skin rashes and lesions are increasingly commonplace on the refugees' limbs.

Over 150,000 people have been confirmed killed and thousands have been missing in walls of tidal waves triggered by a 9.0 magnitude underwater earthquake - the world’s biggest in 40 years - which struck deep in the Indian Ocean off the west coast of Indonesia’s Sumatra Island December 26.

In the restive Indonesian Aceh province, the tsunami worst-hit area, the scene could prove even worse at the first glance.

With garbage seen scattered everywhere, survivors found no other way but to sleep in large refugee tents nearby a drainage ditch in Cut Meutia hospital complex, Lhokseumawe, after the tidal waves that washed both homes and villages.

“I caught a cold because I've been sleeping near the ditch from the first day until now, without a blanket. The only thing I have is this thin mat,” M. Nasir, 51, an Indonesian survivor was quoted by the Jakarta Post as saying.

Naisr, a fisherman before the tsunami catastrophe, had no other place to go after his village, Kuala, was washed away by the destructive tidal waves.

The Cut Meutia hospital complex, one of the busiest refugee camps in Lhokseumawe, is home to some 3,427 refugees from five Indonesian villages.

Seeking shelter with his wife and five children, Karisyam, 36, a Kuala village resident, found no other place to go but the slimy refugee camp to settle in.

“If my son had not been sick, I wouldn't want to sleep in this tent. It has no lamp and there are so many mosquitoes,” said Karisyam.

Karisyam's two-and-a-half-year old has been suffering diarrhea since the horrible tidal waves.

After the earthquake hit Asia, hundreds of millions of dollars were collected swiftly across the world to help send relief supplies to the victims in an unprecedented scene of solidarity.

The World Bank offered last week $250 million for tsunami relief, bringing total aid contributions from around the world to nearly $500 million, the United Nations said.

The British public has donated 32 million pounds (45 million euros, 62 million dollars) for victims of the Asian tsunami, with calls to an aid line hitting a peak of almost a million an hour, charity organizers told AFP Friday.

Such world figures as UN Secretary General Kofi Annan and outgoing US Secretary of State Colin Powell also rushed to visit areas affected by the tidal waves.

They were both horrified at the scale of the disaster, and both, separately said it was the worst ever disaster they have ever seen.
