如果大家有注意看在今天特朗普总统的发布会中美国CDC官员安东尼·弗契回答记者关于目前应对疫情方法是否有效。他的回答还只是强调个人卫生（包括洗手）、不到拥挤的地方去。他也没有提到戴口罩。而且他还讲到：Our （healthcare） system is designed very well, and the system we’vedesigned is telling us what we are doing now is the best (way to protect us).
现代的口罩无论厚薄一般都分为三层：内层是由非常纤细柔软的材料做成，不但让佩戴者感到舒适，同时可以吸附打喷嚏或者咳嗽者喷出来的飞沫。中层有过滤功能。外层表面光滑使病原菌不容易粘附同时有挡水的作用（当然，不同型号口罩挡水能力不一。以美国使用的外科口罩为例，有surgical mask level I, level II, level III. 而就挡水能力而言，以level III最强，level II比较差，level I 没有挡水能力）
D: If you don't wear a mask properly you're also spreading the virus.
F: You learned from the western medical science, I judge by facts and logic.
D: It doesn't make sense. It's airborne. Your mask is not tight. You have to change the mask every few hours which most people don't do. The spread of a lot of viruses is from virus surviving on hard surfaces.
D: If you can breathe with a mask on, you can breathe in the virus. As simple as that.
F: But, it reduces the chance of virus going into your mouth and nose. A medical face mask can filter very tiny particles. Understand?
D: No, oh my god you missed a lot of hygiene knowledge. That's not the only places it enters your body. How do you eat? With your hands. How do you see, with your eyes. Is your mask covering those areas? No.
D: There are many different medical masks, they do not filter virus, Dad, don't forget I work in a hospital. Why are you trying to be an expert in this topic and spread false information. In order to wear a N95 mask properly you need to be mask fitted.
D: In the hospital we are all mask fitted with a personalized size to our face.
D: You are not mask fitted.
D: When it's properly fitted, it's very hard to breathe. You can't wear it for more than an hour because you will not get enough oxygen. That's how tight the mask is. You can't breathe and need to change to new mask.
A girl biked over 300 km to Wuhan to help patients
Translation Story from a Chinese Media
Translated by Xiaozhou
Recently a girl in her early twenties biked over 300 km from her home village to Wuhan to go to work to help patients who are infected coronavirus. She works as a laboratory technician for a Wuhan hospital.
She was visiting her parents on vacation prior to Chinese New Year. A few days later, since the coronavirus outbreak, Wuhan was locked down. All public transportation is shut down.
During these days many patients with fever are pouring into her hospital, waiting to be assessed, to see if they are infected by the coronavirus. Her laboratory’s work load immediately increased. As she a healthcare professional, she feels obliged to return to work and help patients and assist her coworkers. In fact the hospital laboratory does need her, as only three people work in the laboratory. It is very difficult to test so many cases with limited staff. One of her co-worker is aged and continuously worked over 10 days.
However, she cannot return to work easily, as there is no public transportation, and no taxi, nor carpool services will go to Wuhan, as the drivers fear to contact the virus. Therefore, if she chooses to stay at home instead of returning to work, nobody would blame her, as she has reasonable ground to do so and not to risk her health.
In spite of this, with the strong obligation of a healthcare professional she decided to go back to Wuhan on a bicycle. In these days everyone must be quarantined at home to avoid the virus propagation. She had to contact her president to get an electronic permission to access roads to Wuhan. Her parents supported her decision. Her father biked with her together for some distances, and then the girl refused her father continuously to accompany with her to take the risk of the virus infection. It took her 4 days and three nights to arrive at her hospital. She also had to walk for a few hours for many kilometers, as even a bicycle is prohibited in some regions.
On the way many policemen were surprised why a girl was biking on some highways and streets where there were very few vehicles at night. Especially, she biked at nights with her flashlight and her down jacket was soaked by rain. Not only did one policeman stops and questions her. Those policemen were moved by her story; they bought food and water for her and found a carpool for some parts of her journey.
Eventually, she arrived to the front door of her hospital. After knowing how she got back, her supervisors and coworkers were surprised and touched.
Now, the girl is busy with her work and tests over 20 samples a day. She hopes the epidemic will go away as soon as possible.
Wuhan’s coronavirus outbreak threatens the lives of many people. However, a lot of healthcare professionals, scientists, military soldiers, and etc. like the girl, traveled to Wuhan to rescue and save lives, including international efforts.
Wuhan will be successful in defeating the virus. We all bless Wuhan.
