I have gobs of Lysol, a healthy immune system, an health insurance policy i havent used in 4 years, and a positive disposition so when you are ready, Jin- I am. I'll be watching for a thread announcing sales availability.
That, and I figure the way things are going, any shipment from China is likely not going to fast-track through customs anyway.

The human coronavirus 229E (HCV/229E) mentioned above is from several years before the
present coronavirus existed.
This is where you need to go for information on the present epidemic.
https://www.cdc.gov/coronavirus/2019-nCoV/summary.html
You will find lots of updated information.

Well it's annoying that there is so much misinformation.
https://www.ncbi.nlm.nih.gov/m/pubmed/2999318/
It's from a 1985 study... Hopefully by now we know more...
If I did my math right (assuming radioactive decay), we may have to quarantine objects for a few weeks...

Quoting CDC below:
The survival of airborne human coronavirus 229E (HCV/229E) was studied under different conditions of temperature (20 +/- 1 degree C and 6 +/- 1 degree C) and low (30 +/- 5%), medium (50 +/- 5%) or high (80 +/- 5%) relative humidities (RH). At 20 +/- 1 degree C, aerosolized HCV/229E was found to survive best at 50% RH with a half-life of 67.33 +/- 8.24 h while at 30% RH the virus half-life was 26.76 +/- 6.21 h. At 50% RH nearly 20% infectious virus was still detectable at 6 days. High RH at 20 +/- 1 degree C, on the other hand, was found to be the least favourable to the survival of aerosolized virus and under these conditions the virus half-life was only about 3 h; no virus could be detected after 24 h in aerosol. At 6 +/- 1 degree C, in either 50% or 30% RH conditions, the survival of HCV/229E was significantly enhanced, with the decay pattern essentially similar to that seen at 20 +/- 1 degree C. At low temperature and high RH (80%), however, the survival pattern was completely reversed, with the HCV/229E half-life increasing to 86.01 +/- 5.28 h, nearly 30 times that found at 20 +/- 1 degree C and high RH. Although optimal survival at 6 degree C still occurred at 50% RH, the pronounced stabilizing effect of low temperature on the survival of HCV/229E at high RH indicates that the role of the environment on the survival of viruses in air may be more complex and significant than previously thought.

Except the virus dies on any surface after about 30 minutes according to the radio...

Thanks for the good news, but I stopped ordering anything from overseas until this Corona virus thing is over. The entire overseas mail supply chain system needs to get disinfected. Cargo cars & planes, storage warehouses, delivery depots & trucks.

Good to know, I'm anxious to get at the new designs. Thanks for the update!

At 4:30 am I received the update from Jin that they have started normal work again.
