Advice - last updated at 10:00 Sat 08aug20

I would emphasise that, if you use a scorebox then, in general, only the one scorer should be inside.  This is primary advice in ECB circular.

 In addition there should be no sharing of computers, walkie-talkie handsets, pens, pencils. paper, scoreboard accessories. 

Sanatise everything as often as practical.  This is an indoor workplace and a very confined workspace.. The virus can survive 3 days on certain surfaces

There is a high risk of transmission if there are more than one person in a scorebox, unless it is VERY large and has proper social distancing / separating panels (not just a simple screen -  remember how pervasive cigarette smoke is - and covid is likely to be similar)..

HOWEVER, 6 hours indoors with someone who is asymptomatic even sitting sideways at 2 metres and with a mask has a very high chance of transmission.  Indeed a good, civilian style, mask has a lifetime of 4 hours.

A gazebo for the visiting scorer would be more sensible.  If both scorers use PCS Pro on laptops, then the Live Scorer can do end-of-over checks with the Suppprt Scorer electronically.

If possible teams should be uploaded to Play-Cricket in advance and then downloaded so that there is no need for pieces of paper to be handled.

The use of walkie-talkies for communication between the two scorers and between one of them and one umpire would be very useful. 

Every team, no matter how informal, really needs a single full time scorer.

if players take it in turns, then they should not share pens, paper etc - and indeed the area should be sanatised before the exchange. 

Players must not congregate around the scorer.  If the scoreboard consists of loose metal plates, then these should also be handled by a single person.

Remember always that if you contract covid-19, then your whole family is at risk.


JUSTIFICATION & REFERENCES

There is a great deal of draft scientific advice around that still needs review.  I have based the above using common sense and various references, especially:
 https://www.telegraph.co.uk/news/2020/05/20/science-behind-three-key-coronavirus-rules-does-stack/ which quotes a 1930 study of Tuberculosis and goes on to say

At the beginning of March, the Department of Health released guidance on social distancing warning that coronavirus can be spread when people have "close, sustained contact", which typically means "spending more than 15 minutes or longer within two metres of an infected person".
However, the 15-minute rule appears to have been lost somewhere in the recent guidance, even though there is no evidence to suggest anyone has ever caught the virus by briefly passing someone when out and about.
It gives many oither statistics about survival and transmission.

https://www.bbc.co.uk/news/world-53329946 talks about aerosol transmission. 

The New England Journal of Medicine on 17 March 2020 https://www.nejm.org/doi/10.1056/NEJMc2004973  suggests that the Virus can remain viable "in aerosols up to 3 hours"

There is no proof that Covid-19 spreads like Tuberculosis or tobacco smoke BUT I suggest that this is highly likely and risks should be mitigated on that basis.
