感冒病毒的的存活时间有多久
比如说；一个杯子，一个感冒的人喝过了，过多久才能喝那个被子，感冒病毒才会死亡
感冒病毒在适宜的环境中能存活较长时间，如在粪便中能存活100天以上。而在一般的环境中只能存活几天到十几天。

很久。不但在体外，在鼻腔内随时都有病毒，只不过由于鼻子的排毒功能正常，所以病毒数量一直能保持得很低，所以人就没有生病。而且空气中一直漂浮着大量的细菌、病毒，除非是无菌房，任何地方都充满了细菌和病毒。人很多时候没有生病就全是人体自身防御系统的功劳，绝大部分的原因是因为鼻子对外界空气的过滤。了解了人是如何感冒的，你自己就知道怎么样来治疗和预防感冒了。
我们每天所呼吸的空气中本身就漂浮着大量的细菌、病毒、真菌等致病菌，而这些致病菌也通过我们的呼吸不断进入到我们的鼻腔中。但是一般情况下，鼻腔本身的排毒系统能够在15到30分钟之内将致病菌运送到鼻咽处，并最终进入胃中消化掉。此时病毒的数量始终保持在鼻腔免疫系统能够承受的范围之内，所以我们就不会生病。
但当诱发因素如受凉、淋雨、生理因素如经期、怀孕等可以让鼻腔的排毒功能降低，病毒则可以长时间停留在鼻腔内。此时病毒就可繁殖出鼻腔免疫系统无法承受的病毒数量，病毒便大肆侵入人体，我们也就感冒了。（鼻炎患者表现更为明显，即更加容易感冒。）稍后，鼻腔内病毒的基数更大，病毒数量增长更快，于是大量的病毒开始扩散至身体其他部位，这时感冒的全身症状就开始表现出来了。
因此，在感冒的时候，鼻子充当着病毒大本营的角色。只要我们不断地用温盐水冲洗鼻腔，将大量病毒清理出鼻子，越来越少的病毒侵入人体。最终可将鼻腔中的病毒数降低到鼻腔免疫系统能够应对的范围之内。而同时，人体的免疫系统将很快杀灭进入人体的病毒。
所以，自己买个洗鼻壶，在感冒时多用温盐水冲洗鼻腔，尽量保持鼻腔内没有多余鼻涕，可从根本上解决病毒问题。使用此法可在2到4天内治愈感冒，并且不用吃任何药物。平时早晚洗鼻子，可在很大程度上预防感冒，极大降低感冒几率。
同时因为流感和感冒让人生病的过程相同，只是病毒种类不同。所以该方法也可同时减轻流感症状治疗流感和预防流感，对各种流感均适用。以此方法将感冒治好后，洗鼻的次数就降为早晚洗，这样就可以慢慢地调理鼻子，治疗鼻炎了。

11 influenza flu season, scientists and engineers have identified the environmental conditions and surfaces that could enable a highly pathogenic（致病的，病原的） (H5N1) bird flu virus to survive for prolonged periods of time & at least two weeks and up to two months. Among them: The virus appears to thrive at cooler temperatures and low humidity（湿度，湿气） . The study, which could lead to new strategies for preventing the flu virus from spreading, appears in ACS' Environmental Science & Technology, a semi-monthly journal. Joseph Wood and colleagues note that the highly pathogenic (H5N1) avian influenza virus so far has been rare but dangerous in humans, with mortality rates of about 60 percent. Although the H5N1 virus may spread to humans by direct contact with infected birds or other virus-contaminated material, health experts are concerned that the virus could evolve to develop the ability to spread from person to person, and cause serious outbreaks. However, there is little information on how different environmental conditions and materials affect H5N1's survival.
The scientists investigated the ability of a strain of highly pathogenic H5N1 originating from Viet Nam to survive on a variety of materials under different environmental conditions, including changes in temperature, humidity, and simulated sunlight. The materials included glass, wood, steel, soil, and chicken feces. They found that H5N1 survived longer (up to two weeks) at cooler temperatures & around 39 degrees Fahrenheit & but lasted only up to one day at room temperature. The virus also tends to persist（坚持） at low humidity and no sunlight and on certain surfaces, including glass and steel. Although when exposed to simulated sunlight, the virus survived longer on soil and chicken feces compared to the other materials. It could potentially survive for up to two months on those materials, they estimate. At low temperatures and low humidity, the virus actually survived longer on steel, glass, and soil than in chicken feces, a common source for spreading the virus. &Measures taken to contain and inactivate the virus, especially in these areas or conditions, may be warranted（保证的，担保的） ,& the article notes.
