Is that based on actual evidence, rather than wishful think, doc?

It won't like UV, so I'd bet virus on a surface exposed to strong sunlight won't last as long as one that isn't. That's not to say anyone should rely solely on that!

This raises a question from me. Why are some types of flu 'seasonal'?
Doc?

We could spend ages agonising over data, sources and hearsay - picking out the individual pieces that help defend the point we've already set our mind on. Or... we could listen to the overwhelming beseech-ment of frontline workers who are telling us to just stay indoors.

We're all going to find it tough, you're not special or exempt because you have a compulsion to be outdoors, we all do.

As far as I know, seasonality is partly due to virus survival (some don't like hot weather/sunlight) and partly due to human behaviour (we're much more likely to huddle together in under-ventilated rooms in winter).

Just a thought. Money, I mean currency changes hands a lot. I doubt the virus would live long on paper money, but modern notes are plastic.

This is weird, everyone seems to be saying similar things. There was a fellow encouraging people to deliver groceries in cardboard boxes because the virus couldn't survive as long on cardboard. I've spent a significant part of my career building and maintaining containment labs for people to work on viruses and such and devoting a significant effort to making sure everything is hard surfaced and wipe clean. Cardboard and paper being forbidden in many cases. Surely stuff that can be wiped clean is better than absobent?

I think it lasts longer on surfaces like plastic than it does on cardboard when left alone, but plastic is easier to clean. Which is better depends on whether it is likely to be cleaned or not.

Misattributed quote, this was written by a Twitter user about the current situation in the style of Pepys.

"Her Majesty's Men" is the giveaway, in 1664 the monarch was male; Charles II.

A number of reasons I believe. Usually in the winter months people are in closer proximity making it easier for the virus to transmit. Secondly in sunny weather viruses died more quickly from UV light exposure.  I am sure cleverer people than me can think of other reasons.

Maybe a lack of vitamin D through winter makes peoples' immune systems a bit weaker?

Sure that adds in to the mix. Just before I retired I was actively thinking that all people in residential homes should be taking Vitamin D. Some experts were advocating it.

Also your blood doesn't circulate as quickly or thoroughly in cold weather to flush stuff through, inc. white blood cells; & the weather tends to be damper, so supports longer outside survival times for the virus.

Citation needed there I'm afraid. Warmer weather won't circulate your blood faster - however the decrease in physical activity will result in pooling blood in your venous system I guess. Still won't change the concentration of white cells at any point. Was trying to work out how it might be true.

Interestingly when you go out and have a temperature change your spleen contracts and ejects a load of white cells into circulation to cover your vulnerability as the temperature drops .
