legionnaires disease?


My grandmother's doctor said she might have legionnaires pneumonia. I looked up the odds that I could get it from visiting her. Has anyone heard of that winding up in hospitals in New York? I know the disease was going around Syracuse, but i don't know about the pneumonia.
----------

Generally the incidence is linked to exposure to air-conditioning systems on the industrial scale that not regularly cleaned and are good breeding grounds for the legionaires. The typical prevention cleaning includes flushing with a highly chlorinated water.

Most hospitals don't have "central air". Cooled water runs through a pipe into a radiator like unit inside the room where a fan blows air across the coils. This way there's no sharing of recirculated air from room to room and floor to floor.

If the hospital where she stays or works has central A/C the odds are they have an upgraged filter sytem with black lights in the ducts to kill or capture bacteria. If not then anythings possible.

More worrysome is drug resistant tuberculosis.

Good Luck!  (+ info)

Legionnaires Disease?????????????????


What is the common and scientific name for Legionnaires Disease?? PLease Help!! School project!!!!!
----------

This is a water carrier disease in that it breeds where water is present like in an air conditioning System. It's called several names but legionnela bacteria is good enough. Go to Med.com health for more info.  (+ info)

Is it possible to get a legionnaires disease from a oldish warm opened water bottle?


oldish as in maybe less than a day old. But then again it was was very hot and humid outside.
----------

Legionellosis infection normally occurs after inhaling an aerosol (suspension of fine particles in air) containing Legionella bacteria. Such particles could originate from any infected water source. When mechanical action breaks the surface of the water, small water droplets are formed, which evaporate very quickly. If these droplets contain bacteria, the bacteria cells remain suspended in the air, invisible to the naked eye but small enough to be inhaled into the lungs.[7] This often occurs in poorly ventilated areas such as prisons where a condensating air conditioner can spread it throughout the entire room, infecting anyone not immune to the strand of bacteria. Potential sources of such contaminated water include cooling towers used in industrial cooling water systems as well as in large central air conditioning systems, evaporative coolers, hot water systems, showers, whirlpool spas, architectural fountains, room-air humidifiers, ice making machines, misting equipment, and similar disseminators that draw upon a public water supply. The disease may also be spread in a hot tub if the filtering system is defective. [8] Freshwater ponds, creeks, and ornamental fountains are also potential sources of Legionella.[9] The disease is particularly associated with hotels, cruise ships and hospitals with old, poorly maintained pipework and cooling systems. When the disease is caused by contact with the organism in a hospital, it is called a "nosocomial infection."  (+ info)

What precautions are necessary to prevent the spread of Legionnaires disease to other patients in the ward?


legionnaires disease is a water-based respiratory infection. if the infection arose in the ward, search for and get rid of any and all standing water (check inside, under and behind air conditioners, refridgeration units and the like for condensation puddles) Breathing in water vapours containing the pathogen is the most common vector.
if the patient came into the ward with legionnaires, then it's much easier. the pathogen cannot survive for long periods of time in open air, so simply ensure that they have some privacy from the other patients, and have all staff treating them wear masks to prevent possible infection and cross-contamination.  (+ info)

Can you get legionnaires disease from a window airconditioner?


I would imagine that you could, but i think it would be rare. I have never heard of it happening. The only case i have ever heard of actually is a bunch of people getting it from a fountain in a restauraunt.  (+ info)

Is it possible that Bernie Mac was killed by Legionnaires disease rather than pneumonia?


Doubtful. They would have tested for Legionnaire's disease since it is so similar to pneumonia. He died from complications of pneumonia, which is very unfortunate.  (+ info)

What antibiotics help treat Legionnaires Disease? (moxifloxacin HCI?)?


Does Avelox's Moxifloxacin HCI help treat Legionnaires Disease?

it can help with pneumonia so I was wondering if it can help with that too.
----------

Yes moxifloxacin has been effective for treating LD. Newer macrolides like azithromycin has also been effective. Antibiotics that are effective must be able to achieve high intracellular concentrations. These include drugs out of the following classes: macrolides, quinolones, ketolides, tetracyclines, and rifampin.  (+ info)

can some one get Legionnaires' disease just by drinking contaminated water?


from what i read it had to be breathed in.
----------

How Legionnaires' disease is spread

Legionellosis infection occurs after inhaling water droplets that originated from a water source contaminated with Legionella. It must be inhaled through a fine aerosol of tiny water droplets that are strung with the bacteria. This often comes from poorly ventilated areas such as prisons where a condensating air conditioner can spread it throughout the entire room, infecting anyone not immune to the strand of bacteria. Potential sources of such contaminated water include cooling towers used in industrial cooling water systems as well as in large central air conditioning systems, evaporative coolers, hot water systems, showers, whirlpool spas, architectural fountains, room-air humidifiers, ice making machines, misting equipment and similar disseminators that draw upon a public water supply. The disease may also be spread in a hot tub if the filtering system is defective. [5] Freshwater ponds, creeks, and ornamental fountains are also potential sources of Legionella.[6]  (+ info)

Is it dangerous to leave your water heater off. I mean like for bacterial growth like legionnaires disease.


I have a 40 gallon tank, it's in an unairconditioned area 80-100 degrees during the day.
----------

Legionnaires' Disease lives in warm/hot water. Is your water source chlorinated? It should be OK if it is. I don't know why your water heater is off, but it will have to totally re-heat all that water every day which is energy intensive. Maybe you should look into one of those smaller new water heaters that only heat what you will use.  (+ info)

What is the incubation period for legionnaires' disease ?, and how can it be contracted....?


The disease presents as a rapidly progressive, severe, necrotizing pneumonia, accompanied by fever, nonproductive cough, and myalgias.
The onset is abrupt, after an incubation period of 2 to 10 days.
Within 2 days, most patients develop a persistent high fever and respiratory rales.
It involves primarily the lower respiratory tract, although it is often associated with multi-systemic extrapulmonary manifestations. Afflicted patients may sometimes have gastrointestinal symptoms, liver function abnormalities, renal failure , central nervous system complications and cutaneous manifestations which may include erythematous, maculopapular or petechial skin lesions.
Those who abuse alcohol and smoke heavily are also at increased risk.
The organism has been recovered from soils, ponds, water systems, and air conditioning systems.  (+ info)
