根据著名医学杂志柳叶刀（Lacent）文章：冠状病毒肺炎死亡率为15%，远高于SARS的10%，危险性在增高，各位朋友切实重视。  在昨天的个人家庭的防护方法有提到环境高温法，但只是经验，今天已找到相关的理论支持，具体的资料如下英文资料。 环境高温法保持室内环境在20-30度左右，模拟夏天的高温的环境，这个细菌存活的机会就没有了，上次的SARS也是如此，到了夏季才完全解决。因此，有空调的个人和家庭把家里的空调的温度调到最大，湿度调到50%相对湿度，这个病毒就不会有存活.农村的朋友可以采用烧火烧碳，把室内环境温度调整到最大，基本上病毒没有存活的机会。这个已得到医学专业的理论支持。一句话，想办法把室内的温度提高一下20-30度左右。以下是根据2010年Casanoca的文章：在20℃和50%相对湿度，类似病毒在实物表面可以存活3-5天；在4℃，可以存活大约一个月；在40℃，很快死亡。 Effects of air temperature and relative humidity on coronavirus survival on surfaces. Casanova LM, et al. Appl Environ Microbiol. 2010. Show full citation Abstract Assessment of the risks posed by severe acute respiratory syndrome (SARS) coronavirus (SARS-CoV) on surfaces requires data on survival of this virus on environmental surfaces and on how survival is affected by environmental variables, such as air temperature (AT) and relative humidity (RH). The use of surrogate viruses has the potential to overcome the challenges of working with SARS-CoV and to increase the available data on coronavirus survival on surfaces. Two potential surrogates were evaluated in this study; transmissible gastroenteritis virus (TGEV) and mouse hepatitis virus (MHV) were used to determine effects of AT and RH on the survival of coronaviruses on stainless steel. At 4 degrees C, infectious virus persisted for as long as 28 days, and the lowest level of inactivation occurred at 20% RH. Inactivation was more rapid at 20 degrees C than at 4 degrees C at all humidity levels; the viruses persisted for 5 to 28 days, and the slowest inactivation occurred at low RH. Both viruses were inactivated more rapidly at 40 degrees C than at 20 degrees C. The relationship between inactivation and RH was not monotonic, and there was greater survival or a greater protective effect at low RH (20%) and high RH (80%) than at moderate RH (50%). There was also evidence of an interaction between AT and RH. The results show that when high numbers of viruses are deposited, TGEV and MHV may survive for days on surfaces at ATs and RHs typical of indoor environments. TGEV and MHV could serve as conservative surrogates for modeling exposure, the risk of transmission, and control measures for pathogenic enveloped viruses, such as SARS-CoV and influenza virus, on health care surfaces. |
