Coronavirus 3M N95 mask DIY

As WHO announced Coronavirus Global Health Emergency, it's not WHO lost faith in China (because Chinese gov is really acting fast and effectively on it). But for lower income countries and regions, if it became a outbreak, it could be very difficult to contain.  I'm relieved to see that at least the world is in alarm now and institutes and organizations are trying their best to prevent. 

3M, N95 masks are going to be out of stock eventually everywhere in the world, especially considering the fact that most masks are made in China. But mask is mask, just a layer to block virus, it can totally be made by yourself. 

Things to know: 1. People can get the virus from their eyes,  2. It requires a hard layer to block it.

So the essense is a layer of plastic (when you sew a mask yourself, add a layer of PLASTIC in the middle), either you make it into a mask or a cup to cover your head. 

In this photo, my friend who is working as a doctor made this head cover out of file folder. He disinfects the cover and his hands with 75% alcohol every few hours. 

May we all overcome.

What do you need to know about Coronavirus from China?

I think I was under panic attack last week lol...but now there is much more coverage and awareness, I'm at ease. What do you need to know about the Coronavirus?

1. The incubation period is from 1 to 14 days. Before showing any symptoms, the patients are most probably infectious. 

2. Some infected don't show any symptoms, which means some patients are infectious and moving around but we don't even know.

3. It's airborne, meaning a patient's sneeze that floats in the air could infect whole lot of people, especially if that's a "super infectious" ( a Chinese term, don't know if it applies to English). A "super infectious" could infect up to 14 people. The average infecting rate is 2.6, meaning averagely each patient could infect 2.6 others, without prevention.

4. Mask N95, 3M only could prevent it, and keep a 2-meter distance to the patient. Note: N95 3M one-time use are mostly out of stock in bay area, reusable ones still have some stock in Amazon. Get some,  just in case. 

5. Wash your hands as often as possible, each time at least 20 seconds with soup/detergent. 75% alcohol hand sanitizer also works, apply it as often as possible. 

6. Elderly, young and the sick who have weaker immune system have less chance to fight it. 

7. The number is surely going to climb and we have to know about it so to take precautions. 

This is the action that my daughter's preschool takes to prevent the spread.

关于印度和印度的神与神话

印度老公给孩子们念儿童绘本版的印度古史诗巨篇《罗摩衍那》(成书于公元前300年) - 这也是印度排灯节的故事原型,故事中的很多人名地名据史学家考证都是真实存在的,史诗相当于是对当时真实事件的记载。

但这并不是印度教的起源,只是最早的几部有文字记载的印度教故事之一。比罗摩的故事更早远的有神(Shiva,Vishnu和Brahma等主神和众神)与众鬼之间争夺不死水的神话传说,有杜迦女神制服恶魔的神话故事等等等等。

这些更早远得多的神话传说虽没有文字记载,但至今依然完整地流传于民间,比如在排灯节之前二十天的庆祝是杜迦女神节,这是我婆家庆祝的主要节日,头尾十二天的各种祈福仪式,千百年如此。

印度其实自古以来是这么一个地缘概念,几千年来在这个半岛上,因为气候温和偏热,土地肥沃种什么长什么,这里的人们都特别悠闲特别放松,特别能侃特别爱想象特别爱讲故事。

从古印度到现在,隔段时间出个新神来个新故事,到现在叠加起来有千百个神千百个故事。你家把哪个神供奉做主神,把ta的节日当作一年中的主要节日,那是每家的自由。每家的选择都不同,你爱祭拜谁祭拜谁,没有统一标准。

但不管有多复杂,所有的神话故事都是关于正义与邪恶,光明与黑暗,无私与自私的战争,而最后都以光明正义无私的一派胜利告终。

所以印度人大多内心柔软明亮,顶多是几堵泥墙,没钢筋水泥利枪尖矛😁
