Harmonizing to Centers for Disease Control and Prevention by June 2008, there were 17 of the outbreak-related hospitalization out of 1276 instances in United States were caused by Shiga toxin — bring forthing Escherichia coli. E coli O157: H7 besides causes six multistate eruption in which those eruptions occurred in more than one province. ( L. Hannah Gould, 2011 ) In another words, there are estimated 110000 infections, 3300 hospitalizations and 91 deceases in United States caused by E coli O157: H7 each twelvemonth. ( Kate Cummings, 2009 ) Besides, studies of infection instances that are received by The California Department of Public Health ( CDPH ) are about 2067 from 2001-2008. In these seven old ages, they besides received studies of 22 confirmed and 2 suspected of foodborne eruption related to E coli O157: H7 in California. ( Kate Cummings, 2009 ) In history, the first eruption was identified in White City, Oregon, December 1981. Hemorrhagic inflammatory bowel disease caused by E.coli O157 had led to outbreak of nutrient poisoning which kidney failure and decease were the worst instance. In 1993, Washington, there was another disease named Hamburger Disease in which the toxin E.coli O157 was found in undercooked beef and caused 4 decease instances of kids while 100s are sick at that clip. It was so followed by apple juice eruption in 1996 which hemorrhagic inflammatory bowel disease are caused by toxin E coli O157 in apple juice. In July 1996, infected boodle from California has caused an boodle eruption whereby hemorrhagic inflammatory bowel disease has caught by people in Midwest and Northeast. In the same month, eruption of haemorrhagic inflammatory bowel disease had happened in Japan, killing 7 people and 1000s fell badly. It is the worst and most serious eruption in recent history. ( Adams, n.d. )
The most common symptoms after one get infected with E.coli O157: H7 are terrible watery diarrhoea which will go bloody within 3 yearss. This diarrhoea can normally lasts 1 to 8 yearss. ( Thomas G. Boyce, 2012 ) Besides, symptoms such as abdominal hurting and vomitting may besides happen. ( Ingrid Koo, 2009 ) A mild febrility possibly present or sometimes absent in some people. Those symptoms are normally appear 2-5 yearss after exposure to the E.coli O147: H7 and it might be vary from individual to individual. ( SafeFood, n.d. ) There are 2 % -7 % of people that get haemorrhagic inflammatory bowel disease may develop into more serious complication such as haemolytic uretic syndrome ( HUS ) . HUS can affect anemia, thrombopenia, kidney failure and encephalon harm such as shot. It normally develop in 2nd hebdomad after the infection and is characterized by increasing febrility. It is more common in kids below 5 old ages old and aged people. However, haemorrhagic inflammatory bowel disease can do decease in people even without HUS and its complications. ( Thomas G. Boyce, 2012 )
By and large, there are three ways for E coli O157: H7 infection to be transmitted to human. The chief and common beginning of transmittal will be through foodborne particularly in meat. ( Keith R. Schneider, 2003 ) E.coli O157: H7 is able to entree into the meat or specifically undercooked and contaminated land beef. ( WebMD, 2010 ) People get infected when they consume those natural and undercooked meat merchandises. Other nutrient that contact with the feaces of cowss that are infected can besides contaminated and do E coli infection to worlds. Those nutrient include boodle, sprouts, unpasteurised milk, unpasteurised fruit juice, natural fruits and veggies. ( WebMD, 2010 ) Other than that, waterborne transmittal is besides one of the method of transmittal. ( WHO, 2011 ) There is ever the possibility that feaces of human and animate beings that are infected get into the lakes, pools and H2O supplies. Peoples get infection when they drink the H2O that has non been treated with Cl and contaminated by farm animate beings. ( WebMD, 2010 ) Besides, people can besides acquire infected when they by chance swallow the pool H2O while swimming. ( CDC, 2012 ) The last and the of import manner of transmittal will be through contact from individual to individual, normally by direct physical contact. ( Keith R. Schneider, 2003 ) E.coli can distribute from an septic individual & A ; acirc ; ˆ™s custodies to other people. Peoples ever get infected when they eat the nutrient prepared by people who do non rinse manus after utilizing lavatory. ( CDC, 2012 ) This method of transmittal is normally happens in households or child care Centre.
A physician will first surmise a patient get haemorrhagic inflammatory bowel disease when he reports that he hold bloody diarrhoea. A stool trial is performed to observe the toxin produced by E.coli. ( Thomas G. Boyce, 2012 ) After a patient is identified to hold haemorrhagic inflammatory bowel disease, intervention will get down. Normally, people who are infected will acquire better and retrieve themselves within a hebdomad. They frequently do non see the physician and do non cognize that E.coli is the cause of their unwellness. ( WebMD, 2010 ) . The chief and of import facet of intervention is drink plenty of H2O to forestall from desiccation. ( Thomas G. Boyce, 2012 ) Dehydration is the consequence from diarrhoea which cause patient to lost a batch of organic structure fluid. It is unsafe for babe and the aged. Therefore, it is necessary to reconstruct the organic structure fluid by imbibing a batch of H2O. ( WebMD, 2010 ) Antibiotic will non be given and it is non promote to be given to patient as it will increase the hazard of haemolytic azotemic syndrome ( HUS ) . Besides, there is grounds that shows antibiotic will decelerate down the digestion and let toxicant caused by E.coli to be absorbed into the organic structure. ( WebMD, 2010 ) E.coli infection will besides do blood and kidneys jobs. Those patients will necessitate intervention such as blood transfusion and dialysis. ( WebMD, 2010 )
Prevention is ever better than intervention. Although it is difficult to observe and happen out whether the nutrient or H2O we consumed have been contaminated or non, we can still make something that can protect us from the infection. First and first, we can get down from our personal hygiene. Always wash custodies after utilizing the lavatory or altering the nappies. Peoples who have diarrhea should besides maintain that in head to cut down the hazard of distributing. After holding contact with farm animate beings particularly cowss, ever wash manus instantly. Food should besides prepared merely after the custodies has washed. ( WebMD, 2010 ) Next, we should cook our nutrient at appropriate temperature before eat. Ground beef and beefburger should be exhaustively cooked so that the bacteriums inside can be killed. Always avoid natural meat, fruit and veggies. Besides, choose and consume merely pasteurized milk, dairy and fruit juice merchandises. ( CDC, 2012 ) . . Since the infection can besides be transmitted through waterborne, it is of import that we merely drink the H2O which has been decently treated with Cl. We should besides avoid get downing pool H2O while swimming. Other than that, kids who get infected should be isolated and quarantined in place. Avoid directing them to the child care Centre which will increase the opportunity of distributing. ( WebMD, 2010 ) If there is any symptoms of haemorrhagic inflammatory bowel disease, it is advised to acquire a health care supplier or a physician to forestall develop into more serious complication such as HUS.
