SARS LIKELY SPREAD THROUGH HONG KONG APARTMENT'S SEWAGE PIPES

HONG KONG (AP) - A SARS patient with diarrhea infected other people in a Hong Kong apartment complex as the disease apparently spread into homes through a sewage pipe linked to poorly sealed water drains, an official report said Thursday.

More people who came down with severe acute respiratory syndrome in Block E of the Amoy Gardens apartments also got diarrhea, creating huge amounts of contaminated feces that spread the virus through pipes in Hong Kong's biggest outbreak of the flu-like illness, said the health secretary, Dr. Yeoh Eng-kiong.

Rats and cockroaches also may have spread SARS, but only incidentally after they picked it up around the apartments, Yeoh told a news conference.

"They were just passive, mechanical carriers," Yeoh said, adding that rats captured by the investigators did not come down with SARS symptoms.

There is no evidence of airborne transmission, Yeoh said.

At least 324 people were infected in Amoy Gardens, where SARS was also apparently spread through person-to-person contact and in common areas, such as elevators, lobbies and staircases, according to the report made by several Hong Kong government agencies.

The SARS outbreak in Amoy Gardens has been the most alarming in Hong Kong, where the disease has infected 1,297 people and killed at least 65. Four new deaths and 29 new cases were reported Thursday.

About 40 per cent of the SARS cases in Amoy Gardens came from one building, called Block E, that was evacuated at one point with all of its residents moved into holiday camps that were turned into makeshift quarantine centres.

The disease was brought to Amoy Gardens by an infected man who visited his brother there on March 14 and March 19, Yeoh said. The outbreak peaked in Block E on March 24 and there was a lag of about three days later before it spread to residents of other blocks.

Yeoh said that once the virus got into the waste pipe in Block E, droplets that carried it apparently moved up through people's bathroom drains when U-shaped water seals dried out. Fans apparently helped suck the virus particles into homes, he said.

One resident of Block E told The Associated Press the report's findings sounded right and she called on officials to focus on calming the public and stopping the spread of SARS.

"We have long suspected it could be problems with the sewage system - the apartments are so close together," said Anna Yuen, 45, who lives in Block E with her husband and three children.

"We were scared at first but after the isolation, we haven't seen any outbreak like what we had before," Yuen said by telephone. "I believe the situation has come under control."

But Yuen said she'd give the government's handling of the crisis just "70 marks out of 100."

"They have not been quick enough in calming the public," Yuen said.

The pneumonia-like illness has killed at least 166 people and infected about 1,300 worldwide. Mainland China has reported 65 deaths as has Hong Kong. Singapore has 15 SARS death, Canada 13, Vietnam five, Thailand two and Malaysia one.

Meanwhile, the world's second most populous country reported its first SARS case on Thursday.

Authorities in India said a 32-year-old man in the western state of Goa contracted the disease after travelling to Hong Kong and Singapore, S.P. Agarwal, the government's director general of health services, told a news conference. Prashil Varde, an Indian marine engineer, returned home to Goa on April 3, he was treated by a private doctor for cough and fever, two of the symptoms of SARS, said Dr. Shivlal, director of the National Institute of Communicable Diseases. He uses only one name.

The man and his wife, who has not tested positive for the virus, have been isolated, Agarwal said.

The World Health Organization has said scientists have confirmed the identity of the SARS virus, in a key step toward finding drugs to fight it.

In Singapore, airline passengers arriving from some SARS-stricken areas were being scanned for fever by military-grade equipment adapted for the war on SARS.

Those who show up on the camera screen as "hot bodies," or with a temperature greater than 37.5 C, will be pulled aside to have their temperature taken by a nurse, said Evelyn Ong, a spokeswoman at the Defence Science and Technology Agency.

In Beijing, universities said Thursday they have cancelled activities and some classes to prevent the spread of SARS, breaking with earlier official insistence on continuing public events.

The buildings where I work have automatic flush toilets (supersonic, by the sound) and no lids.

don't breath dried deer mouse urine.

Good advice for anyone, I expect! LOL

A SARS patient with diarrhea infected other people...as the disease apparently spread into homes through a sewage pipe linked to poorly sealed water drains, an official report said Thursday.

Good heavens, how many different methods of transmission there can be?

From the World Health Organization;

Wednesday, 16 April 2003 Press briefing:

Close personal contact is the major way that we believe this disease is spread, from person to person, sitting next to you or just in front of you, by something that comes from you that lands on them, as you speak or as you cough.

[InShanghai]

Unfortunately, many toilets (including those in the building where I work) don't have lids any more.

I don't know if I should laugh or cry...

[Dog Gone]

I was wondering when India would get its first case. If the SARS virus gets into the Genges River, there's no telling how fast it would spread.

[buffyt]

My cats prefer to drink straight from the faucet. I wish they could learn how to turn it on and off!

[First Amendment]

The pneumonia-like illness has killed at least 166 people and infected about 1,300 worldwide.

What's with these figures???? I will go search for new SARS articles but aren't these numbers way low??

[riri]

Yes, the cases are more like double that number.

I feel like I am in a bad sci fi horror movie.

Airport heat Sensors Used to Conquer SARS

My husband has a meeting today with some self important executive type who routinely travels to Asia. I told him sit as far away from him as you can, wash your hands after meeting with him and if he is coughing or looking blue don't come home. LOL

The reporting here and lack of familiarity is leaving a bit of a misconception in how SARS spreads through pipes.

The way the bathrooms are set up in Asia is the bathroom floor has a vent/drain. You can literally hose your bathroom clean and the water washing down the floor drain. The drain also acts as a vent for the tub/shower.

Anyone that has lived over there, anyone from the U.S. or other Western Country, knows to put a wet towel over the vent becuase sometimes you get an odor from it.

I'm certainly no expert in how SARS spreads, but these pipes are more akin to vents than they are to pipes. They are actually an air to air vent and all the aparments are linked by them.

Not sure how much difference this makes to anyone except that you can bet now that Westerners are not the only one sealing off that little floor drain/vent.

[MissBaby]

Note that the story says no airborne transmission.

I personally think the reporter is mixed up. It is airborne transmission through vent pipes (see my post 30) that they are calling sewage pipes.

[per loin]

Cheap plumbing. If they have floor drains, they should have trap primers to insure the water seal against such rise of vapors.

[aristeides]

If Asian plumbing is what has allowed the spread, that would explain why there has been so little secondary spread in this country. But it doesn't explain Toronto, does it?

[aristeides]

Speaking of Toronto, here's what may be a case of SARS spreading from one condo to another: Condo residents may have been exposed to SARS.
