We are in California. We are required to stay home with exceptions for groceries, gas, exercise (not in groups), etc.

This morning we picked up our first order for groceries. We find groceries on the internet, find an available pick up time and in a few days go there at the scheduled time and call from the pick up area. They bring over the groceries and put them in the trunk. It worked smoothly. The supermarket had just set up an online ordering service late last year so the timing was lucky.

Less smooth was washing the groceries. I wore rubber gloves and used soap and water. Plastic bags and surfaces might harbor virus for 3 days or longer so I carefully put them in the trash. There was a lot of hand washing.

If anyone finds some smoother ways to disinfect groceries other than the seat-of-the-pants process that I used this morning, please post the links.

I had a look around and found this article from the Seattle Times. It echoes most others in that food should be washed in water at roughly the the same temperature of the food itself but do make sure all the surfaces around the food are sanitised with food appropriate sanitiser. Hope its helpful.

This recent publication I believe is the best available at this time on how long the Covid 19 is viable after emission. It covers several surfaces including plastic. Plastic kept the virus viable the longest at 3 days or longer. Stainless steel was 2 days. Cardboard 24 hours. Airborne was 3 hours. There were a lot of plastic packages in my groceries so I would not trust any information that is what I call cut-and-paste information. Find the original publications or measurements if possible.

Here is the publication.

Please give your references. Your last paragraph conflicts with this publication.

I had been saying that the virus lives for 3 days on stainless steel and plastic. It looks like on stainless it is 2 days (below).


I think this publication is important because it may be the best available information for Covid 19. Are there any others? Chinese measurements?

Here is the publication on surfaces and airborne viruses. The stainless steel says 2 days, I've been saying 3 days. For Covid 19 aerosol it says that it "remains viable in aerosols throughout the duration of our experiment (3 hours), ". So it could be longer than 3 hours. I hope everyone will read this publication and get the numbers. Fausci was on TV and I interpret that the test could involve the ability to culture the collected virus as expressed by a "Titer" number. I am not going to interpret what a Titer number means or the what the reduced exponent means in their presented results. The viability decreases.

Aerosol and Surface Stability of SARS-CoV-2 as Compared with SARS-CoV-1
TO THE EDITOR:
A novel human coronavirus that is now named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (formerly called HCoV-19) emerged in Wuhan, China, in late 2019 and is now causing a pandemic.1 We analyzed the aerosol and surface stability of SARS-CoV-2 and compared it with SARS-CoV-1, the most closely related human coronavirus.2
We evaluated the stability of SARS-CoV-2 and SARS-CoV-1 in aerosols and on various surfaces and estimated their decay rates using a Bayesian regression model (see the Methods section in the Supplementary Appendix, available with the full text of this letter at NEJM.org). SARS-CoV-2 nCoV-WA1-2020 (MN985325.1) and SARS-CoV-1 Tor2 (AY274119.3) were the strains used. Aerosols (<5 μm) containing SARS-CoV-2 (105.25 50% tissue-culture infectious dose [TCID50] per milliliter) or SARS-CoV-1 (106.75-7.00 TCID50 per milliliter) were generated with the use of a three-jet Collison nebulizer and fed into a Goldberg drum to create an aerosolized environment. The inoculum resulted in cycle-threshold values between 20 and 22, similar to those observed in samples obtained from the upper and lower respiratory tract in humans.
Our data consisted of 10 experimental conditions involving two viruses (SARS-CoV-2 and SARS-CoV-1) in five environmental conditions (aerosols, plastic, stainless steel, copper, and cardboard). All experimental measurements are reported as means across three replicates.
Figure 1.Viability of SARS-CoV-1 and SARS-CoV-2 in Aerosols and on Various Surfaces.
SARS-CoV-2 remained viable in aerosols throughout the duration of our experiment (3 hours), with a reduction in infectious titer from 103.5 to 102.7 TCID50 per liter of air. This reduction was similar to that observed with SARS-CoV-1, from 104.3 to 103.5 TCID50 per milliliter (Figure 1A).
SARS-CoV-2 was more stable on plastic and stainless steel than on copper and cardboard, and viable virus was detected up to 72 hours after application to these surfaces (Figure 1A), although the virus titer was greatly reduced (from 103.7 to 100.6 TCID50 per milliliter of medium after 72 hours on plastic and from 103.7 to 100.6 TCID50 per milliliter after 48 hours on stainless steel). The stability kinetics of SARS-CoV-1 were similar (from 103.4 to 100.7 TCID50 per milliliter after 72 hours on plastic and from 103.6 to 100.6 TCID50 per milliliter after 48 hours on stainless steel). On copper, no viable SARS-CoV-2 was measured after 4 hours and no viable SARS-CoV-1 was measured after 8 hours. On cardboard, no viable SARS-CoV-2 was measured after 24 hours and no viable SARS-CoV-1 was measured after 8 hours (Figure 1A).
Both viruses had an exponential decay in virus titer across all experimental conditions, as indicated by a linear decrease in the log10TCID50 per liter of air or milliliter of medium over time (Figure 1B). The half-lives of SARS-CoV-2 and SARS-CoV-1 were similar in aerosols, with median estimates of approximately 1.1 to 1.2 hours and 95% credible intervals of 0.64 to 2.64 for SARS-CoV-2 and 0.78 to 2.43 for SARS-CoV-1 (Figure 1C, and Table S1 in the Supplementary Appendix). The half-lives of the two viruses were also similar on copper. On cardboard, the half-life of SARS-CoV-2 was longer than that of SARS-CoV-1. The longest viability of both viruses was on stainless steel and plastic; the estimated median half-life of SARS-CoV-2 was approximately 5.6 hours on stainless steel and 6.8 hours on plastic (Figure 1C). Estimated differences in the half-lives of the two viruses were small except for those on cardboard (Figure 1C). Individual replicate data were noticeably “noisier” (i.e., there was more variation in the experiment, resulting in a larger standard error) for cardboard than for other surfaces (Fig. S1 through S5), so we advise caution in interpreting this result.
We found that the stability of SARS-CoV-2 was similar to that of SARS-CoV-1 under the experimental circumstances tested. This indicates that differences in the epidemiologic characteristics of these viruses probably arise from other factors, including high viral loads in the upper respiratory tract and the potential for persons infected with SARS-CoV-2 to shed and transmit the virus while asymptomatic.3,4 Our results indicate that aerosol and fomite transmission of SARS-CoV-2 is plausible, since the virus can remain viable and infectious in aerosols for hours and on surfaces up to days (depending on the inoculum shed). These findings echo those with SARS-CoV-1, in which these forms of transmission were associated with nosocomial spread and super-spreading events,5 and they provide information for pandemic mitigation efforts.

Sorry to hear that and you have my best wishes - keep hydrated and I hope that you're friends and family that are firstly safe and secondly able to get you your food and meds. The self isolation has been tough but I am nearly at the end of it. TT has been one of the few avenues out of this room I am in at the moment and I am grateful for that. @S&V-not_dead_yet in post #5 put together a really good list of vits/food supplements that can also help. Will you have to be self isolating for 3 weeks?
Now here's something crazy. I just read an article on COVID in Southeast Asia. There is a case reported, whom was quarantined for 14 days, tested negative, got released. 6 days later, the patient exhibited symptoms and got test positive. It is unclear when the patient really had it. But, to be sure, 3 weeks is necessary.

That could be the case with several cases that have been self isolating, should they not have had it then they would run the risk of getting it when they left isolation. So difficult without testing, I think the South Koreans got it right by testing everyone. That way no doubt.

Today is the 7th day of isoaltion for the family. I'm feeling a bit more like it and my son and I fancied a little bit of kitchen tennis. God bless my patient wife who cooked a fabulous curry and ignored our odd framed volley! I lost 7-4 or 7-5 and was never likely to win - he's to good.

I hope you are all staying well and weathering the storm.

I've tried sanitising my stuff by capturing them on high speed video at 240 fps in broad daylight, with little to no motion blur.

But in all seriousness...yikes, I'm glad my city hasn't got it bad enough despite being a stone's throw from the PRC.

Cool. Do you feel better since starting this thread?

Maybe you can share some ideas in the other thread at https://tt.tennis-warehouse.com/index.php?threads/lets-gather-great-ways-to-practice-tennis-in-these-virus-times.666279/

Nice to see other guys playing tennis no matter where.

Hey thanks for the good wishes. The last two days, Tuesday and Wednesday, my temperature has been back up over 100 hence the radio silence as did nothing but sleep but today it has returned down to a manageable level with meds. It is the worst virus I have had to fight but I have really believe in our collective will to beat this invisible threat. The kind wishes from the forum alone has been so heartening and a source of real strength. Something I will not forget.

The UK has now issued strict instructions to work from home or stay away from any groups following suit with other countries in the world. Several industries and retail stores are no longer allowed to trade temporarily. During all this and whilst isolating it is possible to get really anxious (my mind has strayed a few times) and I've put together a few ideas below to try to stave off the worrys:

- remind yourself that the current restrictions are for a good reason and they are only temporary. What we took for granted will happen again in time.

- Try not to get obsessed with all the bad news, be aware of it but only rely on official sources.

- use the home time to do something that you haven't done before, for example a craft, read a book that has been sat on the shelf for ages, painting, for us guys a few of those household jobs we've deferred for to long. I quite like the idea of learning a new language but we'll see.

- lots of tennis exercises for us tennisnuts, the post from Top Tennis Training earlier in the thread is excellent and focuses your mind on your passion which is your sport. Visualisation is a skill good tennis players possess and now is the perfect opportunity to practise it.

- plan the demise of your rivals on the tennis court. You'll have plenty of time to figure out some good tactics and surprise them when you get back on there.

- plan a routine on a daily basis and how you will spend your time. Try to follow normal routines as much as possible like getting up at same time and going to bed at same time. If you're not happy with your usual routine then take the opportunity to change it. Reflect on it.

- other exercises could be cleaning the house, dancing to music (not my bag but you never know!) - do post it if you do, going up and downstairs, keep an eye on sitting and make sure you get up and move regularly.

- Get as much sunlight and fresh air as possible in the garden. Keep the windows open so long as it's not to cold.

- keep checking the TT threads and posting. Have loved Jollys thread on posting vid of you playing well - recommended.

There are more but for me I am already making plans for a kitchen tennis rematch with my son once my temperature has settled. Hes been skipping, doing cardio work, ab work and a whole load of shadow swings - so to even the balance I may ask that we play with frying pans. That might slow him down a bit. I'll post the results.

I will try and keep posting useful activities and tennis related stuff now I'm feeling a little better. Keep safe everyone and look after yourselves! [emoji123][emoji106]

halarious, but looks better than just sitting on the couch all day. Me and wife and son my take this up. :) Me and wife play but son doesn't play anymore but he'd do this. He's been sent home from college and bored as hell. we were going fishing but the fishing place we like is swollen to hell fish all up on the damn bank swimming around...

Cant wait to see the vid - please post. Looks like it will be a round Robin between the 3 of you! Have a good one and stay safe!

Take care, mate. I heard France is telling people to stay off the vitamin I (as in ibuprofen), and stick with paracetamol, as there has been a correlation between ibuprofen users and critical cases.

I've stayed off NSAIDS for the time being just in case. I've read some articles that suggest it's really only people with an existing problem with that family of meds - but taking no chances. Until the gov specify something I will pass on them.

The rematch this evening using household kitchen utensils. My theory that I could narrow the gap using pans was just that theory - lost 7-5. Good pick me up after a tough couple of days for both me and my son. Those pans must weigh half a kilo so thinking about adding 200g to my Tour 100P to bring it up to 505g strung ;). The plough was amazing and you save so much on stringing! Stay safe everyone.
