We go to the clinic whenever we are really sick, but sometimes that stay can lead to another illness on top of that first medical issue. These health care-associated infections or Nosocomial infections occur because a hospital puts a lot of people with infections in one place, many of them with low immunity, without strict procedures for maintaining sterile conditions; these can cause pathogens to spread.
Catheter UTI
Sometimes patients can't urinate due to injury, surgery or other reasons.
When that happens, a nurse or doctor may install a catheter that automatically
drains urine from the person's bladder. One end of the tube goes through the
skin and into the bladder; the other end attaches to a collection bag.The problem is that the bladder and urinary tract are usually germ-free environments, and introducing an external tube can allow pathogens to get into the bladder and cause a urinary tract infection, the most common hospital-acquired infection.
