And now these three remain: faith, hope and love. But the greatest of these is love.

I'm not good with the old school Asian model minority stigma where we won't speak up or stand up for ourselves. In times like now, we truly truly need to stay united. Lets fight this virus TOGETHER!! Wash your hands, practice social distancing, take this seriously, stay safe ❤️

[Jeremy Lin @JLin7]

And I dont wanna hear about no German measles/Spanish flu bc everyday Asian-Americans inc ppl I know are threatened and physically attacked. I dont give a crap about the history of names rn. What I do know is this subtle anti-Chinese message only empowers more hate towards asians

[Jeremy Lin @JLin7]

🤦🏻‍♂️I wish you would powerfully support the vulnerable people that will suffer due to our mismanagement of this virus, including those that will be affected by the racism you’re empowering

[Jeremy Lin @JLin7]

Can you honestly tell me there is ZERO anti-Chinese sentiment in all his characterizations of the virus? Can you honestly tell me Asians aren't being unfairly physically attacked today in the US? Is it that hard to use coronavirus or COVID-19? We playin the blame game in a crisis

[John Burn-Murdoch @jburnmurdoch]

I’m no epidemiologist, but I am a #dataviz specialist, so here are some thoughts on coronavirus and log scales:

1) In the initial outbreak phase, a virus like this spreads exponentially not arithmetically, i.e a log scale is the natural way to track the spread
