    手上存活5分钟。意思是5分钟前有病毒,抠鼻屎也没事了啊
  • 行走的拖拉机
    我都是挖完鼻孔,揉完眼睛,才想起来是不是应该洗洗手去

    看一些相关报道,应该是15秒到30秒就足够了。







    以下是Wiki上说的:

    Alcohol-based hand sanitizer is more convenient compared tohand washingwith soap and water in most situations in the healthcare setting.[3]It is generally more effective at killingmicroorganismsand better tolerated than soap and water.[4]Hand washing should still be carried out if contamination can be seen or following the use of thetoilet.[5]

    Hand sanitizer that contains at least 60 % alcohol or contains a "persistent antiseptic" should be used.[16][17]Alcohol rubs kill many different kinds of bacteria, includingantibiotic resistantbacteria andTBbacteria. 90% alcohol rubs are highly flammable, but kill many kinds of viruses, includingenveloped virusessuch as theflu virus, the commoncold virus, andHIV, though is notably ineffective against therabies virus.[18][19][20]

    90% alcohol rubs are more effective againstvirusesthan most other forms of hand washing.[21]Isopropyl alcohol will kill 99.99 % or more of all non-spore forming bacteria in less than 30 seconds, both in the laboratory and on human skin.[16][22]

    The alcohol in hand sanitizers may not have the 10–15 seconds exposure time required to denature proteins andlysecells in too low quantities (0.3 ml) or concentrations (below 60%).[4]In environments with high lipids or protein waste (such as food processing), the use of alcohol hand rubs alone may not be sufficient to ensure proper hand hygiene.[4]

    For health care settings like hospitals and clinics, optimum alcohol concentration to kill bacteria is 70% to 95%.[23][24]Products with alcohol concentrations as low as 40% are available in American stores, according to researchers atEast Tennessee State University.[25]

    Alcohol rub sanitizers kill most bacteria, and fungi, and stop some viruses. Alcohol rub sanitizers containing at least 70% alcohol (mainlyethyl alcohol) kill 99.9% of the bacteria on hands 30 seconds after application and 99.99% to 99.999%[note 1]in one minute.[21]

    For health care, optimal disinfection requires attention to all exposed surfaces such as around the fingernails, between the fingers, on the back of the thumb, and around the wrist. Hand alcohol should be thoroughly rubbed into the hands and on the lowerforearmfor a duration of at least 30 seconds and then allowed to air dry.[26]

    Use of alcohol-based hand gels dries skin less, leaving more moisture in theepidermis, than hand washing with antiseptic/antimicrobialsoapandwater.[27][28][29][30]


    在大多数情况下,酒精洗手液比用肥皂和水洗手更方便。它通常比肥皂和水更有效地杀灭微生物和更好的耐受性。如发现有污染或如厕后发现有污染,仍应洗手


    应使用含有至少60%酒精或含有“持久性防腐剂”的洗手液。[16][17]酒精摩擦杀死许多不同种类的细菌,包括耐抗生素细菌和结核细菌。90%的酒精摩擦是高度易燃的,但能杀死许多病毒,包括包膜病毒,如流感病毒、普通感冒病毒和艾滋病病毒,但对狂犬病毒明显无效


    90%的酒精按摩比其他洗手方式更有效。[21]异丙醇可以在30秒内杀死99.99%或以上的非孢子形成细菌,无论是在实验室还是在人的皮肤上


    洗手液中的酒精可能没有10-15秒的接触时间,不足以使蛋白质变性和溶解细胞的数量过少(0.3 ml)或浓度过低(60%以下)。在有高脂或蛋白质废物的环境中(如食品加工),仅使用酒精洗手液可能不足以确保适当的手部卫生


    对于医院和诊所等医疗机构,杀灭细菌的最佳酒精浓度为70%至95%。东田纳西州立大学的研究人员称,在美国商店里可以买到酒精浓度低至40%的[23][24]产品


    酒精洗手液可以杀死大多数细菌和真菌,并阻止一些病毒。含70%以上酒精(主要为乙醇)的洗手液,使用后30秒内杀灭手上99.9%的细菌,一分钟内杀灭99.99% ~ 99.999%的细菌[注1]


    对于卫生保健,最佳的消毒要求注意所有暴露的表面,如指甲周围、手指之间、拇指背部和手腕周围。手酒精应该彻底擦在手上和前臂下部,至少持续30秒,然后让空气干燥。[26]


    与使用抗菌肥皂和水洗手相比,使用含酒精的洗手凝胶使皮肤干燥程度降低,在表皮上留下更多的水分。[27][28][29][30]
