Legionaire's disease is treated with patiem fermagnate anfd forulin how do i know ??? it was my job
No it is absolutely not Legionnaires. As has been posted here many times, Legionella is a water-borne pathogen. It is spread through inhalation of aerosol droplets containing the bacterium. So many people are still posting here stating their fear of dirty aircon filters at hotels, but those absolutely do NOT harbour Legionella.
Read here:
http://en.wikipedia....i/Legionellosis
Note that in this article, it is stated that 40% to 60% of all cooling towers contain Legionella. So if 40% of northern Thailand's contain Legionella, they are on the low end of the scale. I really think this is all unfounded hysteria, a la swine flu, bird flu, SARS, etc.

According to www.legionella.com, air conditioners are not a source of Legionaires disease.They were suspected to be the source of the original American Legion outbreak in a Philadelphia hotel, but new data suggests that the water supply was the culprit, as was the well publicised outbreak in the BBC building.The most popular theory is inhaling droplets of water containing Legionella, but new evidence suggests that it is aspiration or choking.
Sorry wrong, it was the A/C system. The cooling tower( part of A/C system) on the roof exhausted the water droplets off the roof down the front of the building at the entrance. The legioners and the wives were entering and leaving on a daily basis being exposed, breathing in the droplets of water carring the bacteria also they were partying, drinking so reduced immune system.
The water droplets that carry the bacteria have to be a certain size, if to small the bacteria cannot ride if to big you cannot breathe the droplet into your lungs so no infection. That is why you very seldom here of some one getting this diease from a shower droplets to big but not that it could happen.
The bacteria is usually found in water obtained from the surface rivers, creeks and lakes if your water supply comes from a well not to worry so much. The source for outbreaks have been found up to 4 miles away so these little buggers can carry a good distance.
Donot worry about being infected by this nasty bacteria which poses as a virus that is why it took them a while to figure it out, if you have a good immune system you will generally have a bad cold.

Well,the experts say different. Incidently, Legionella pneumophila, which is resposible for 90% of all cases, can lurk in any water supply pipework as a biofilm. Plastic,wood and rubber are particularly good at attracting this.

"figures cannot be revealed as it would hurt tourism, Injai said"
So responsibity concerning Tourists health once again is only taken into account as long as it does not interfere with the Countries income?
Sad County!

I have three 21 year old aircon units in my rented house. How do I clean the filters?With water or just shake them ss I have always done? Thanks in advance Dave..No good asking the landlord for help or new units...lol
Domestic air cons have to be cleaned twice a year by specialised staff.
Not only the filters need to be cleaned, but also the gas pressure to be checked.
In Pattaya the cleaning of the filter costs about THB 300 per air con; a gas top-up, when necessary, can cost up to THB 600 per air con, depending on the quantity of gas needed.
If the gas pressure is low or inexistent, your electricity consumption will go up and the cooling effect will go down.

I would suggest that the filters be cleaned by the home owner at least weekly, it only takes a small amt. of dirt to raise your electrical usage.

What do the experts say that is different? If you get your water from a surface source contaiminated then the water supply will fill the cooling tower which is made from wood, plastic, and othe materials. The bacteria will then grow in this very friendly enviroment. As most cooling towers use a fan to either push or pull air across the cooling medium, the contaminated water, water particles with the bacteria are exhausted into the air
ready for some unsuspecting person passing by to inhale the airborne contaminated water particles.
No the part of the A/C system most people see, in their room was not responsible that is a closed loop system. The part of the system that delivered the bacteria in a arosol to be breathed in was the cooling tower a major part of the a/c syatem that no ones see. Yes it was fed by pipes delivering contamined water.

Well, I've just had 3 brand new Aircons fitted in my home and ever since then I've had a cold and a permanent cough. Does this mean I have Legionaire's disease now?
No it means you could be allergic to the AC,i have the same problem,i never use the AC in hotels (ask for a fan),(patlum),nor do i have it at home,sorry to say you may have wasted your cash,i bought a potable AC 2000Bt,you fill with water or if you need to be more cool you can put ice in,works great,i also use ceiling and/or a portable stand up fan,if it's really hot i have a supply of damp towles in the fridge to dowse down with (paian) easy simple,AC is overrated.
Just to be pedantic, the portable units you are describing are not actually Air-Conditioners. They are used extensively in the US (swamp coolers/desert coolers is, I believe, the laymans term) but in fact are only effective in areas of low humidity. Guess what .... Not Thailand where Humidity is king. They work on the theory of evaporative cooling (cooling is achieved by evaporation, radiation convection and conduction). If you live in arizona they are a great buy, in Thailand......Naaah
In regard to other posts which are more On topic, why shut down the Hotel ??, generally in western eyes it is seen as a sign that the management acknowledges the potential risk and wants your custom, so they do a thorough cleaning before exposing guests to the potential again, ie Scarborough UK, that huge imposing victorian hotel, bunch of people got sick, legionnaires confirmed, they (at hotel expense) transferred everyone else to another hotel, shut down the hotel for professional cleaning, paid expenses for everyone inconvinienced, and also paid for any private medical expenses. As a result, 6 months later Hotel was again at full capacity, manager noted that the hotel actually gained customers due to their swift actions and total bill payments, not an ambulance chaser in sight because hotel paid all claims without going to court.

Just to add another spoke to the Cleaning wheel, I work for 6 months a year on a small (60-80 metre) research vessel,. We have central AC to the critical areas, ie Instrument room, engine control room, general deck areas and individual AC to some of the newer cabins (added after a refit) Every week we have a shedule for AC maintenance and every 2 weeks we have a schedule for individual AC filter cleaning. This is adhered to 100%, preventative maintenance saves money, no contest, try explaining that to Thai managers

I used to stay at a hotel in Bangkok where I would get sick every time I stayed there. I suspected that there was some kind of bacteria in the air con and stopped staying there and stopped getting sick when I visited Bangkok..
Yes - so you weren't in Chiang Mai and you survived for 3 weeks without treatment......
