Does spraying the streets work against coronavirus.Contractors were seen in Reading doing just that on Wednesday evening.
As the COVID-19 pandemic continue, you will probably have seen photos and video of workers in protective gear using high-pressure sprays to cleaning our streets.
You may have asked yourself if this really makes much difference to the risk of coronavirus transmission. If not, why would governments expend time, energy and money doing it?
The conditions required for disinfectants to work, we suspect these activities are as much about authorities being seen to do something as about actually stopping the spread of COVID-19.
The likely effectiveness of spraying streets and other public places depends on how the virus spreads, how the disinfectants work and what conditions these are used in.
