请学医的核实一下。原来还奇怪为什么有防护的医务人员还死那么多。看来N95 N100口罩也不是100%安全。 The US Centers for Disease Control and Prevention (CDC) recently reported that the SARS virus can be transmitted by fomites and aerosols and that infection can occur via the mucous membranes of the mouth and eyes (the conjunctiva).3 The CDC report3recommended use of an N95 respirator (a half-mask) for protection against SARS, but the finding that transmission can occur through the eyes indicates that a half-mask respirator is not appropriate for this purpose. This conclusion is supported by 3 other recent publications4,5,6 reporting that N95 respirators do not appear to be effective. This ineffectiveness is due to the particle size of the SARS virus, poor fit and inadequate eye protection. Instead, use of an elastomeric (rubber) full-face respirator with an ultra-low penetrating air (ULPA) filter, rather than a high-efficiency particulate air filter, is warranted (e.g., North full-face respiratory 7600 series
