WITH coronavirus cases plummeting, lockdown measures are set to ease next week - and pubs, restaurants and hotels will be allowed to reopen.
There is strong evidence that a disease cannot be passed on if an infectious person is effectively isolated. Studies measuring droplet production found high rates of transmission reported in several choirs and religious groups. Those considering this mitigation would need to factor in how long it takes to kill the virus and how frequently the surface is touched.
More hand washing stations should be installed to increase frequency of hand washing and avoids potential crowding around sink facilities.Physical partitions are thought to be good at blocking larger droplets of the virus. This can be as simple as opening a window or vent, or installing a form of mechanical ventilation system such as an air purifier.For those with the luxury of air conditioning systems, set the airflow distribution so that fresh air is reaching all areas of the space.
But experts say these devices are not readily available and their effectiveness will depend significantly on design and positioning.Propping open doors can lead to larger ventilation flow rates and reduce contact risks, such as touching door handles. But it only works when people are sitting right by the system and without careful design, one study found they could transport exhaled pathogens and increase indirect exposure.Mobile UV and hydrogen peroxide vapour systems can reduce surface contamination levels in room spaces of various sizes and have been applied to vehicle use in some cases.There are also cost, environment and toxicity issues, according to the scientists.
Several studies have found SARS-CoV-2 - the virus that causes Covid - on shared equipment such as computer mice and keyboards.Where it is not possible to do so, a cleaning regime between users must. be implemented, the experts say.There's evidence that the virus can survive on different materials for a considerable time.
It's more appropriate for places such as transport hubs, shops or corridors in busy offices or schools.

Husband & I just had some real fun with this...An engineer building bespoke cars outside in a bubble made from washing up water surrounded by screens wearing a space age suit in a howling gale & the pissing rain or blazing 30C but the workshop is empty, clean & ventilated 😂😂
