閱讀能力得零分？我係歐洲買貨
全部都係MADE IN EU
全部都係MADE IN EU
香港買到既3M就真係有可能Made in 支那 la
真係弱智 歐洲冇支那貨？
上面位巴打問P95可唔可以代N95 你話唔得
唔識唔好亂答人

口罩上面自然會寫住MADE IN邊嫁啦-.- 你係咪第一日買野?

How is SARS spread?
The primary way that SARS appears to spread is by close person-to-person contact. SARS-CoV is thought to be transmitted most readily by respiratory droplets (droplet spread) produced when an infected person coughs or sneezes. Droplet spread can happen when droplets from the cough or sneeze of an infected person are propelled a short distance (generally up to 3 feet) through the air and deposited on the mucous membranes of the mouth, nose, or eyes of persons who are nearby. The virus also can spread when a person touches a surface or object contaminated with infectious droplets and then touches his or her mouth, nose, or eye(s). In addition, it is possible that SARS-CoV might be spread more broadly through the air (airborne spread) or by other ways that are not now known.

傳播途徑
「沙士」主要透過人與人近距離的接觸，通過患者咳嗽或打噴嚏時產生的呼吸道飛沫而傳播。當患者的飛沫附在周邊人士的口、鼻或眼睛的黏膜上時，就有機會傳播病毒。病毒亦可間接地經雙手觸摸被污染的物件表面後，再觸及口、鼻或眼睛而傳播。

A basic reproduction number (R0) of approximately 3 is consistent with a disease spread by
direct contact or larger virus-laden droplets that travel only a few meters rather than by
lighter airborne particles. By contrast, if a disease is transmitted by aerosols, a single person
can infect an entire room by coughing, as can happen with measles and influenza. If so,
then simple infection control techniques, such as frequent hand washing can go a long way
toward slowing the spread of the disease.

https://jamanetwork.com/journals/jama/article-abstract/2749214
Findings In this pragmatic, cluster randomized clinical trial involving 2862 health care personnel, there was no significant difference in the incidence of laboratory-confirmed influenza among health care personnel with the use of N95 respirators (8.2%) vs medical masks (7.2%).

mers sars 呢類由coronavirus引起acute resp syndrome都係droplet transmission，正常人根本無需要戴n95攞苦黎辛。如果會接觸到aerosol嘅情況(比人0距離顏射)，你戴n95對眼咪又係一樣奶野 n95係預你玩插喉suction或者入隔離病房呢d會有液體橫飛aerosol generating procedure嘅情況先要戴，仲要係配成套ppe+標準嘅gown up degown procedure。 先唔好講普通人會唔會遇到呢d情況，如果你遇到嘅話，你就算戴n95我唔信你其他位置唔奶野(眼，衣物，頭髮等位置一樣會沾染飛沫)。
結論就係，唔需要過度焦慮，n95提供更高嘅防護唔代表你用得著，我更唔認為你地會有足夠嘅IC知識同埋ppe去發揮n95優勝嘅點，但佢更高嘅價錢同埋不適感我就肯定你會有親身嘅體驗

想問3M8511得唔得
之前手快快見有就買左盒
見佢話help reduce exposure to airborne biological particles，但就唔知有冇用

得,
不過都係講句, 睇你點用
