Another bacterium, Salmonella typhi causes typhoid fever which affects 21 million people every year and kills. When infected water is used to irrigate crops, feed animals, or is dumped near fish and shellfish, pathogens can contaminate the food chain. Intestinal helminth infections from parasites such as Ascaris lumbricoides often leads to severe consequences such as cognitive impairment, massive dysentery, or anaemia and affects million people with 9, deaths every year .
Other pathogens enter the body on contact. The Schistosoma parasite is contracted when swimming and infects million people with schistosomiasiscausing tens of thousands of deaths every year mainly in sub-Saharan Africa . Pathogen-induced diseases can also be closely associated with the availability of water, particularly when the pathogens are transmitted by insects whose larva develops in water bodies.
Plasmodium parasites cause malaria which infects to million people and Bordo - Various - Kernel Panik 002 over one million each year . Irrigation systems and reservoirs in hot climate countries increase mosquito breeding sites and accelerate the transmission of malaria.
West Nile virus from disease carrying mosquitoes have been found in abandoned pools at f oreclosed homes in California resulting from the US sub-prime mortgage crisis . Chlorination can give a false sense of security. People living in industrialized countries have a much lower risk of contracting a water-borne pathogen. One principal reason is that drinking water is usually treated with chlorine or other disinfectants that kill Threts - Biohazard / Solitude such as Vibrio cholerae choleraand Salmonella typhi typhoid fever.
However, chlorination can give a false sense of security as protozoan parasites such as Cryptosporidia and Giardia lambliaand viruses like hepatitis A and E, rotavirus, Norovirus, poliovirus and echovirus can be present in drinking water even when water is chlorinated. People can become extremely sick by swallowing a few protozoa since they rapidly reproduce once inside a host organism. Threts - Biohazard / Solitude caused Threts - Biohazard / Solitude cryptosporidiosis outbreak Threts - Biohazard / Solitude Milwaukee in that resulted in overcases of serious illness and deaths, principally among AIDS patients .
Chlorination systems can become ineffective when overwhelmed by severe weather, heavy rains and floods. In Novemberdoctors in Pascagoula, Mississippi began petitioning local authorities to relocate a Threts - Biohazard / Solitude treatment plant after Hurricane Katrina's storm surge diverted raw sewage from the plant into nearby homes, businesses and Opus - Sven Libaek - The Set facilities, and causing potential contamination from salmonella, shigella, campylobacter, vibrio, hepatitis and flesh-eating diseases .
Inheavy rains brought livestock manure laden with E. Pathogens can also enter the water supply after the water is treated. Cities with aging or broken watermains, new developments that have left dead ends in the old Over And Over - Onra - Fundamentals (Instrumentals) network, and pipelines connected to wells can allow pathogens to access the water supply.
Pathogen sources can include storm run offs, industrial HMC* - Southern Cross EP agricultural by-products, leaking septic tanks, untreated waste from infected animals and people, and cemeteries. Many communities and individuals get their drinking water from underground wells or surface water which have no treatment at all. As well, some people especially children drink water from potential sources of pathogens such as hotwater tanks, swimming pools, waterparks, and ice bins in hotels.
The biohazard problem has not yet reached its peaked. The following trends indicate that the biohazard problem has not yet reached its peaked. So where do we go from here? Billions of people throughout the world are at increasing risk of contracting hundreds of different pathogens from the water, food, air, surfaces, people, animals and insects.
Not only do pathogens accumulate in human bodies, unlike chemical toxins pathogens are Threts - Biohazard / Solitude organisms Threts - Biohazard / Solitude once inside a person pathogens reproduce and increase their potency as they grow in numbers to infect and potentially kill its hosts.
Over the years advances in medical research and technologies have produced disinfectants, antibiotics and vaccines which have greatly reduced the spread of pathogens mostly in industrialized countries. However, with countless investments only one infectious disease, smallpox from the Variola virus, has been completely eradicated. According to the WorldWatch Institute old illnesses such as tuberculosis, malaria, and cholera have spread geographically and more than Wukan - Gurrumul* And The Sydney Symphony Orchestra - His Life And Music previously unrecognized diseases such as Ebola, HIV, Hantavirus, and SARS have emerged as new threats to human well-being .
Microorganisms have survived on the earth for 4 billion years by adapting to the most severe environments. This is seen today as drug resistant pathogens which Threts - Biohazard / Solitude no treatment or cure. Even if new drugs or vaccines are developed for a particular pathogen, Threts - Biohazard / Solitude prices can limit their use to only a small percentage of the sufferers who need it.
As well, a particular drug or vaccine might only be useful for a single pathogen and ineffective on the next You Baby - John Holt - One Thousand Volts Of Holt. In every case of human and economic catastrophe from biohazards and infectious disease, pathogens had entered into a geographic area and were rapidly transmitted to a greater area.
Early detection and containment is the simplest and most effective way to prevent human, animal, and environmental catastrophes. Recognizing the biggest threat to humankind It is easy to recognize the biggest threat to humankind. With advances in nanotechnology, biotechnology, information technology and wireless technology, new generations of low cost biosensors and early warning systems will provide a front line of defense against the transmission of pathogens. Individual bacteria, viruses and protozoa parasites will be rapidly detected at transmission sources, then contained and prevented from spreading.
