The droplet protocol in the hospital I work at requires that we wear protective gowns/face masks/gloves over our clothing when there is a risk of infectious disease. If we are not able to protect our clothing or if we are dealing with a patient in the ER and are unsure of a diagnosis, if we get sneezed on or are exposed to blood/bodily fluids, we are either required to change our scrubs (which, unlike you think, we always have extras and what you see in Walmart may very well be a clean pair of scrubs)or apply disinfectant spray on the areas exposed. Like I said earlier, do not clump all health care workers together. I am sorry that the hospital you were in had poor protocol. Where I work, we MUST wash hands after every patient contact, we MUST wear gloves, we MUST protect the patients and ourselves from exposure. We as health care workers are NOT responsible for the emptying of hazardous waste materials or trash, that is up to the HASMAT department of the hospital and the hospital custodians. As far as washing my scrubs, there is no need to disinfect the washer, that is what HOT WATER, bleach and LAUNDRY soap is for. I wash my scrubs in the same washer I use to wash my kids' clothes...and THEY HAVE NEVER BEEN SICK due to cross contamination from a patient I have seen. By the way, it is not the laundry soap or bleach that kills bacteria/viruses...that only helps a bit. Nor is it the hot water. There is this little thing in the washer called an AGITATOR...look up why soap is not exactly needed to kill germs. It is the hot water and FRICTION that kills the germs. That is why steam cleaning is so effective. Oh, and we can always wash our scrubs at work, if needed...which I have done before. As far as not changing your sheets goes, there is a REASON we don't do that unless it is necessary. We, as far as protocol goes, have a responsibility to ourselves and our other patients to lessen the risk of exposure. Unless needed, the sheets are NOT changed until the patient leaves. And by needed, I mean as far as blood/stool/urine/vomit goes. Just ask one of the many women on this forum like myself that have been in the hospital for preterm labor. Or the many other people who have been in the hospital for extended amounts of time. They not once changed my sheets either. Well except for the time my magnesium bolus caused me to vomit. I got those protective pads placed under my bottom and those were changed. My sheets were changed when I was moved to a gurney to be sent to the OR for an emergency c-section, the bed was wiped down and disinfected, like protocol states.
And as far as acanthamoeba goes, there are several kinds, acanthamoeba keratitis is a rare disease where amoebae invade the cornea of the eye, acanthamoeba granulomatous encephalitis is an opportunistic protozoa that rarely causes disease in humans but in patients with it, they are usually immunocompromised, with diabetes, cancers, AIDS, lupus, or even alcoholism. Acanthamoeba can increase MRSA numbers by 1000-fold. MRSA can infect and replicate inside of Acanthamoeba polyphaga, which is WIDESPREAD throughout the ENVIRONMENT (I capitalized that because it is not JUST HOSPITALS where this can happen, it can happen ANYWHERE). Because A. polyphaga can form cysts, the cysts infected with the MRSA can act as a mode of AIRBORNE dispersal for MRSA, not DIRECT CONTACT, but AIRBORNE. Meaning you would get it from breathing in the bacterium, not through touching someone's scrubs. That is why hospital ventilation equipment is being looked at as a cause for hospital-related MRSA and NOT THE HEALTHCARE WORKERS THEMSELVES. There is hospital protocol set in place for prevention of airborne MRSA, including new ventilation and filtering systems. I need to add that we as healthcare workers, and patients themselves, are partially at fault for these mutated bacterium. These bacterium became resistant to our antibiotics because we gave out antibiotics to patients with simple infections their bodies could rid themselves of. Such as parents with a child with a simple bacterial ear infection. These practices of handing out antibiotics for every little infection have made bacteria, once killed by the antibiotics, resistant to the antibiotics now. These practices were more common when Methicillin came out, which was in 1959 but continued until recent medical research was done and it was found that the risk of taking the antibiotics, which one of the risks was creating a resistant bacterium, greatly outweighed the benefits, especially when it comes to infections that the body can generally take care of itself or with a weaker antibiotic or other treatment, such as ear infections, some skin infections, and some respiratory infections. Methicillin is no longer clinically used, but term methicillin resistant staphylococcus aureus (MRSA) continues to be used to describe staph aureus strains resistant to all peneicllins. Methicillin is no longer manufactured because the more stable and similar penicillins such as flucloxacillin, dicloxacillin, and oxacillin are used medically. As far as the resistant bacterium go, advances have been made in medical research and there are now other antibiotics that can be used to kill MRSA, which is not a death sentence.
Oh, and do not call names on this forum, especially obscene names or you can be reported. And thank you, but if "Labworker" is supposed to be insulting to me, it isn't. I am proud of the field I work in, making a difference in my patients' lives by diagnosing their cancers early, diagnosing what they have so they can be cured, or letting them have joyous news, such as finding out they are expecting a little one.
