is legion's disease spread through air vent systems
135410
Legionnaires' Disease is caused by  Legionella pneumophila.  It casuses pneumonia and typicall abdominal cramping.  It typically grows in air vents with moisture.  You can read more of it here: http://www.bbc.co.uk/dna/h2g2/A882371

Not sure what you're looking for besides the obvious....\n\nAirborne spread is much faster than person-to-person.  For a person-to-person disease, the infected person has to come in physical contact with someone else to spread the disease.  For airborne transmission, the infected person just needs to have been in the same room.

Quite a lot of people have bad allergies (to things like dust, pollen, and animal dander). Also, influenza is easily passed around, simply by being around a sick person's sneeze, or touching a faucet in a public bathroom (This applies to seasonal colds as well).

A sealed (pessurised) system is normally about 1.5 bar. Open vented - depends on the head, 10 meters/ 33'  = 1bar

If material was released into the air and they didn't clean the place well it could be in the carpets, cabinetry, false ceiling, and air ductworks or air conditioner. It's shouldn't be in the plumbing, or radiating from the walls, unless of course they still have a big stash hidden there but if the police were smart enough to use dogs they shouldn't have missed anything. Pull off any air vent covers and vacuum them out well and  the vents too. Empty shelves and cupboards, (look for false panels), and scrub them out. Then at least you won't be worried about it.

Uh, The sources on air purifiers creating toxic fumes seem to be reliable.  On the other hand, you have such a difficult time with spelling that I can't really trust your scientific knowledge.

The only thing that might be of concern from what I have read, if true, is that the folds of skin have a higher degree of holding bacteria which increases the chance of infections and transmitting STD's.\n\nUsing a condem might help reduce spreading of STD's, but every 1 out 5 have defects and if not properly worn tend to roll off \nand therefore the spred of disease is still present.

Short Answer:\n\n\n   Infections spreading, through valve-less veins, in the head are most commonly overgrowths of anaerobic normal flora that begin with tonsilitis & dental infection. \n\n     See:\n       http://www.otohns.net/default.asp?id=15225\n\n\n   Patients with this infection are operated on by DMD OroMaxilloFacial Surgeons, so they may be the best ones to answer questions about this.  \n \n     See:\n        http://www.allexperts.com/postQuestion.asp?Expert=37196&Category=966\n         (above link is to ask a DMD OroMaxilofacial Surgeon)\n\n\n\n\nLonger Explanation:\n\nVeins draining the sinuses (like the cavernous sinus) in the head don't have valves, so blood moves only by pressure diferences.  When localized infections get inflamed,  it increases the pressure in that area.  Infections around the mouth & nose can spread through the valve-less veins into the skull cavity.  Once inside the skull sinuses they can infect the brain usually causing at least nerve dammage, if not death.  \n\nSee:\nhttp://cats.med.uvm.edu/cats_teachingmod/gross_anatomy/head_and_neck/pages/veins.html\nhttp://web.indstate.edu/thcme/duong/head.html\n  (Note: search link for infection [with Ctrl-F] )\n\nThe most common infections to spread via these veins today are tonsilitis & dental infections, that resulted from an overgrowth of normal flora (overgrowth of bacteria normally living in the healthy body).  Most of these [10:1] are anaerobic bacteria (bacteria that do not use & often can not survive in an oxygen rich enviornment).  Most of these infections will spread to infect the sinuses, nose or ear.  \n\nSee:\nhttp://www.otohns.net/default.asp?id=15225\nhttp://www.nlm.nih.gov/medlineplus/ency/article/001047.htm\n\n\nYou may want to ask your question to Dentists\nAbout AllExperts offers Dentistry Expert Q & A\nSee:\nhttp://experts.about.com/q/Dentistry-966/Systemic-infection.htm\n(above link is a sample answer)\nhttp://experts.about.com/q/Dentistry-966/index.htm\n(above link is Previous Dentistry answers) \nhttp://www.allexperts.com/postQuestion.asp?Expert=37196&Category=966\n(above link is to ask a DMD OroMaxilofacial Surgeon)\n(Note: DMD's operate on patients with these infections) \nhttp://www.allexperts.com/postQuestion.asp?Expert=68880&Category=966\n(above link is second form to reach same DMD)\nhttp://allexperts.com/getExpert.asp?Category=966\n(above link describes other dentists willing to Answer)\nhttp://allexperts.com/central/howtoask.shtml \n(above link describes the technical asking process) \n\n\n\n\nAsking DMD (both dentist & MD) above is probably best \n(most qualified, familiar & open to answering Q's)\n\n\n\n\n\nif you want to contact others...\n(who will likely be less quaified & less open) \nwriters on this topic may be open to corresponding\n\nNote: you can only correspond when others agree to\nmost physicians have demanding & hectic schedules \nso be very polite, appreciative & flexible\n. .

it could be mono or a flu virus

theres a whole bunch of conspiracy theorys on this if you search around.  I found this one article though that was kind of interesting http://archives.cnn.com/2002/WEATHER/05/27/bugs.weather/index.html\n\nif we can use microbes to make medicine why not control the weather with them... really both concepts are pretty crazy but the medicine one is already done.

pneumonia is caused by a bacteria, so u need to acquire the bacteria in the first place.  smoking will cause damage to the alveoli causing fibrosis and build up of mucus along the cilia lining.  so smoking increases your risk by making you more susceptable to bacterial invasion

thi happen in a frien of mine in singapore, and as far as i can guess it can in here UK to. specialy with this hot weather...\n\n\n\nFrom a friend.\nWe purchased a "Takada" Air Cooler from Carrefour about 4\nmonths ago but\ndid not realised that it can be a breeding ground for mosquitoes.\n\nLast week I noticed a  few young mosquitoes flew around my son's writing\ndesk, close to where we placed the Air Cooler for my son in his study\nroom.\n\nThen, I was wondering where could these young mosquitoes come from and I\nwas thinking whether could it be from the water in the Air Cooler.\n\nYesterday morning, I was burdened again to check the Air Cooler and to\nmy horror when I drained out the water from the Air Cooler and was\nshocked to find about 20 huge mosquito larvae flowed out from the Air\nCooler.\n\nYesterday, I reported in writing to Dr Yaacob Ibrahim, the Environment\nMinister from the Ministry of the Environment to request him to urgently\ntake the appropriate action to advise the Public to drain out the water\nfrom their Air Cooler to check for mosquito larvae because no one,\nincluding ourselves, suspect mosquitoes can fly into the Air Cooler and\nbreed from there. Secondly, I requested him that in order to prevent the\ngeneral Public from innocently breeding the mosquitoes in their Air\nCoolers at home and the office, the Ministry should ban the sales of\nthese Air Coolers ( there are several brands in the departmental\nstores). We hope this feedback will help in the prevention of the Dengue\nFever in Singapore.\n\nWith this email, I hope you can inform your staff and your friends to do\nsome regular checks on their Air Cooler if they own one, before their\nFamily become victim of the Dengue Fever. \nThank you.

Pubic lice (crabs) are normally spread by sexual contact and are considered a sexually transmitted disease, but can also be spread by sharing clothes or bedding. A common misbelief is that infestation can be spread by sitting on a toilet seat. This is not likely since lice cannot live long away from a warm human body. Also, lice do not have feet designed to walk or hold onto smooth surfaces such as toilet seats.\n\nI would still always wipe clean or cover with toilet paper the toilet seat when using public toilets.

Legionella Pneumophila & Legionellosis\n       \n \n \n  \nLegionella Pneumophila & Legionellosis - Legionella is the genus of bacteria, which gives rise to the risk of infection from diseases, collectively known as legionellosis. These consist of both pneumonias and non-pneumonic varieties. The species Legionella pneumophila presents the most serious hazard, which is mainly, but not solely, responsible for causing legionnaires' disease. This is a pneumonia which has serious effects and is fatal in 10-12% of cases.\n\nLegionella is widespread in both natural water sources and artificial water systems. It proliferates where temperatures are favourable (20-45 Degrees C), nutrients available and water is stagnant or recirculates. Infection can then occur by the inhalation of aerosols or particles generated from the source.\n\nParts of this document © Crown Copyright - originally produced and published by the UK's Health & Safety Executive.\n\nAdditional Information\n\nFor further information and expert assistance please call us on +44 (0) 161 240 2245 or email info@legionellacontrol.com.

First of all, be sure to be there when they do the job!  We had our ducts cleaned and got robbed by one of the workers who thought we wouldn't miss a few "minor" personal items.  But, even though they didn't believe us at first, we reported it to the police and the company and he got caught!\n\nSecondly, ask if they not only remove the vent covers but clean those too.  Ask how they clean them and if they use their own cleaning supplies and take the vent covers outside to clean--not in your bathroom or kitchen sinks, using your personal towels.  Ask if they clean up the lint that falls into the room with a vacuum cleaner.\n\nThey should have a crew of at least two people to put the hose in and clean out the vents and one to clean the vent covers and the area around the vents where the lint falls.\n\nThey should clean the air intake vents and cover also.  Some try to sell you on cleaning out your actual AC/HVAC unit coils.  I don't see the need for that, but if they insists it is needed, get them to show you the dirt in there that they will be cleaning out. If they can't show you, chances are they will not be able to get in there to clean it.\n\nThey should change the air filter, but be sure they don't try to sell you some heavy-duty, life-time guarantee filter that supposedly never needs to be replaced.  Those don't let enough air flow through.  The medium grade ones changed every few months or so work the best.  You can buy those at a home improvement store and change them out yourself during the year.\n\nMake sure that they don't damage your walls with their big machine, trying to get it down the hall and around corners.  They damaged our walls, too and we had to have them plaster and paint it again.\n\nJust because the company has a nationally recognizeable name doesn't mean they will do the best job. Often these are owners who hire flunkies to do the work who are thieves and don't care.  It would be better to get a local guy that has been doing it a long time and can furnish you with references of satisfied customers.

Respiratory infections are contagious and are spread by droplets when people cough or sneeze.  You should spray hard surfaces with antibacterial spray and let it air dry and wash your linens in hot water and use bleach or antibacterial cleaner.  Pay attention to door knobs and sink handles as if he is considerate he prob. covers mouth and nose when coughing but would touch door knobs and sink levers with contaminated hands.  \nIt would be highly unlikely to catch his ear infection as how would it get out unless ear is draining.\nGet yourself some zinc lozenges and start taking them as soon as you get symptoms.  It will reduce the duration and severity of cold symptoms by kicking your immune into high gear.  This really works well but only in the first 72 hours of symptoms so get some to have on hand in case.  I always keep them in case.  Once at work some people were out 2 and 3 days with cold virus and I only had mild symptoms for 3 days and they were symptomatic for 2 and 3 weeks.  \nGood Luck

The bird flu has not been spread outside Asia yet to my knowledge. It is possible from research studies of the Bird Flu that it could become airborne, spread through breathing, if that happens, a world panic would occur. Hopefully it doesn't and researchers will find a cure for it.
