A member live in China near Wuhan wanna talk about SARS-COV-2
It's 2:13 am, can't sleep, laying on bed, at home about 200km from Wuhan City, Hubei province, China.Not good at English, so I will try my best to describe more exactly.
I work in Wuhan City, go back home 1 day before the public transport suspend.Have passed 14-days self-quarantine period.
We have more than 1 thousand confirmed cases here in my hometown until today, but half of them has been cured.(With whole another province's medical human resource support)
So I wanna to talk about some about the virus, mostly based on what I have known.
First Part:The Virus
The virus still can't confirm the original, but followed by research, the virus still don't have much mutate(less than 0.1%), so we human are delling the same virus now.
The new corona virus is easily infected, we have some sample here in China, one guy in supermarket have close range contact(less than 1 meter) with an infected person(confirmed after that) about 15s, then confirmed infect in next 2 days.Patients covered all age range from new born baby to old man.
The infected will show symptom about 1-7 days after first contact, most should less than 14 days.But in this period, the infected can also spread virus not like 2003 SARS.
Second Part:Vector and Spread
Yes, the virus mostly spread by attached on human body liquid(micro size victor) when infected patient cough.Also can spread by direct contact virus(like use hand with virus on it contact your eyes).
But the infect to human basically depends on the amount of virus, like with open air enviriment, the micro liquid spread to air by cough will be not thick enough to include enough virus to infect normal healthy person.
Third Part:Protect and Control
First at first: DON'T PANIC
Follow your local goverment advice and CDC advice, protect yourself, it's not a big deal.(If your gov and CDC are not trying to hide something like Japan goverment, they request only if you have fever longer than 4 days and have trouble with breathing you can get thr virus-infect-or-not test you believe that???)
The virus is NOT THE BIGEST problem, the PANIC IS.
N95(US)/FFP2(EU)/KF94(KOR) can block most of the nano particle like virus or the micro liquid particle it attached on.If you wanna go high risk area like hospital which have confirmed patients, or crowd facility like railway staton/air port.
If can't get the high level masks above, use surgery masks also can protect you from short range contact, cause these masks can't block virus itself but can block the nano particle which have virus on it.
WASH HANDS AND CLEAN SURFACE
Wash hands!Even if only use water!
After contact public used objects like door handle or elevator buttons!
If possible use chlorinated disinfectant or 75% alcohol clean suspicious object surface before touch.
STAY AWAY FROM CROWD
I understand some of you can't understand why our goverment place strict order to let citizen stay at home, cause we live in diffirent society and we have the crowded street and lots of population in every single city.The isolation means the best protection.
Just stay away from crowd if un-nessesary.You never know who has been infected before they get the RT-PCR test result.
Italy goverment are doing well, reduce human contact will help reduce confirmed cases.
After writing, it's 3:25 am now.
Hope everyone OK.
