Because of the AIDS epidemic, the concern of healthcare workers and patients about medical gloves’ quality and barrier effectiveness has increased in recent years.
The relative merits of nitrile, latex and vinyl as a barrier to transmission of infectious agents, especially viruses, had been examined by studies. For being a successful barrier, a particular material must prevent penetration. Such as the passage of pathogens, through closures, permeable materials, seams, and pinholes or other faultiness in the barrier material. When penetration happens in a medical glove, it is through imperfection in the material, like pinholes, tears, etc. Other important factors in barrier efficiency contain the resistance of a glove material to mechanical stress. Resistance to chemical collapse by agents such as disinfectants and alcohol used to prepare and clean an operating room is also important. Glove quality is appraised in order to guarantee strength, durability, and reliability during clinical use.
Researchers made a lot of studies about gloves’ integrity. They have found that virus penetration happened in 5 – 10% of control gloves, whether latex or vinyl. Gloves were subjected to three different levels of use designed to imitate glove stresses during clinical patient care.
When vinyl and latex gloves were given needlestick punctures meant to serve as positive controls to measure virus leakage, an unexpected result occurred in this study. Visual and viral leaks is formed only in the vinyl gloves, and not in any of the latex gloves. The researchers ascribed this result to the elastic resealing property of latex.
Other studies have used dye exclusion to estimate glove barrier protection properties. In another study, vinyl and latex gloves were subjected to stresses designed to simulate 15 minutes of clinical activity in an intensive care unit. When tested for dye exclusion, testers found that a failure rate of 53% for vinyl gloves, compared to 3% for latex gloves.
Nitrile gloves are the most protective gloves when they compared with vinyl and latex gloves. Nitrile gloves are prefered by healthcare workers and patients more than other types of medical gloves because of their barrier protection properties.
There are various types of protective gloves. These gloves work to prevent hurt to your hands. The type of gloves you wear is very important, because depending upon the type of the gloves, you can be protected from chemicals, blood, cuts, burns and frostbite. They type of material the gloves are made from that determines the risks you are protected from.
The HIV/AIDS epidemics disease is spreading through countries of African tribes. Though it is not right to speak of single African epidemic disease, Africa is with no doubt harmful virus affects that region. Inhabited by more than 12% of world’s population, it is estimated that Africa have over 60% of AIDS infected population. Lots of deadliness of epidemic in African tribes has to do all with deadly synergy between AIDS/HIV & Tuberculosis, although this particular synergy is not at all limited to Africa. Actually Tuberculosis is world’s most infectious destroyer of women of the reproductive age and leading source of death of people with AIDS. Almost all of newly infected people stay in developing world, mainly southern Africa. Majority of them are the young adults, some of whom don’t know that they are been infected. This epidemic disease is leading cause of the death in Africa. Worldwide, AIDS is a leading source of death for adults between ages of 15 to 59 years.
