What causes diaper infection?

There are many causes of diaper infection, but most of them are caused by not paying attention to the baby's cleanliness and hygiene. There are also many types of diaper infection. Generally speaking, the symptoms are caused by urinary tract infection. After the occurrence, you must receive formal treatment, so that the chance of improvement will be greater and prevent it from affecting the normal development of your baby.

Pathogens usually enter the urinary tract by one of two routes. By far the most common route is through the lower end of the urinary tract - the opening at the end of the penis in men or the urethra at the vulva in women, resulting in ascending infection that spreads upward through the urethra; another possible route is direct infection of the kidneys through the bloodstream. Urinary tract infections can be caused by bacteria, viruses, fungi, or many parasites.

Any pathogenic bacteria can cause urinary tract infection, but the vast majority are Gram-negative bacilli, such as Escherichia coli, Escherichia coli, Proteus, and a few are Staphylococci and Enterococci. Most bacteria ascend from the urethra and enter the bladder, causing cystitis. The bacteria in the bladder then migrate to the kidneys through the ureters, causing pyelonephritis. A few cases are infected through blood or urethra.

The incidence rate in girls is significantly higher than that in boys. The reasons are:

① Girls’ urethra is short and wide, and the urethral sphincter is weak, making it easy for bacteria to invade. The activation function of the bladder-ureter junction in girls is weaker. When the pressure inside the bladder increases, it is easy to cause urine reflux and cause kidney infection.

③The distance between girls’ urethra and anus is relatively close, making them easily contaminated by bacteria.

Urinary tract infections are generally divided into upper urinary tract infections and lower urinary tract infections. According to the route of bacterial invasion, it can be divided into: bloody infection, ascending infection, and descending infection. Most women have ascending infections because their urethra is straight and short, so bacteria can easily ascend to the bladder and cause infection.

In addition, the external opening of the female urethra is very close to the vaginal opening and anus, and is easily contaminated by feces and bacteria excreted in the anus. In addition, the ability of elderly women to completely empty their bladder is reduced, so bacteria can easily multiply in the residual urine. The most common clinical disease is lower urinary tract infection, also known as cystitis, which is a common and frequently occurring disease in elderly women. Its incidence rate is 8-10 times higher than that in men, so prevention is very important.

In a healthy person, the urine in the bladder is sterile, that is, there are no bacteria or other infectious microorganisms present. The tube that discharges urine from the bladder to the outside of the body, namely the urethra, does not contain any infectious pathogens or only has very few pathogens and will not cause infection. However, any part of the urinary tract can become infected, and these infections are usually classified as lower or upper urinary tract infections. A lower UTI is an infection of the bladder or urethra; an upper UTI is an infection of the kidneys or ureters.
