I heard on the radio it's spread by the virus on surfaces, not just airborne. For this reason those masks are not effective.
Is this true?
Goo idea for a thread by the way, we need facts!

The virus spreads in airborne droplets so if theyre on surfaces there is a risk.
General use Surgical facemasks dont protect the wearer from airborne germs,theyre for preventing the wearer sneezing coughing or breathing on a patient.
Thats why care staff in isolation units wear positive pressure headgear.
You need quite sophisticated full face masks that filter gram-negative bacteria or virus to counter airborne pathogens.
Pathogens can be breathed in, ingested by mouth or absorbed via mucosa (your eye tear ducts are an entry way,hence why goggles or face shields are worn.)
Antibacterial spray will kill most hard surface infections.
Hospitals usually use Antibacterial hand cleaners like hibiscrub.
If its a contact spread pathogen then any handle,shopping trolley,food surface,money etc would be a risk....but for now it appears the biggest risk is airborne transmission between people in close proximity.

That makes sense, thanks for the explanation NomadCris |

If it came from animals can they contract and spread the virus around the world?

There are a few different coronavirus that are found in the wild, this one is believed by Chinese researchb to have come from trafficked Pangolin and Bats.University rsearchers of Cambridge and Nottingham have questioned that connection.
Its also been found in 33+ different wild species around Wuhan and (supposedly) in pet dogs in the affected area.

Coronavirus: Can it spread via door handles? And other questions www.bbc.co.uk/news/world-asia-china-51176409I don't like the way that they reply on this............. Buying goods from China, apart from the fact that the world is running out as they've shut up shop, there's the question of will anything you buy carry the infection and would ordainary household cleaners be good enough to sanitise such goods. |

Ive trawled through a lot of medical info,a lot of it quite technical, but found this Dr on youtube who is making a decent job of explaining the issue.

As the above Dr Campbell has explained,theres a worry this is spread not just by airborne droplets but by airborne aerosolisation which means it can travel as minute particles over greater distances than just coughed or sneezed droplets between people in close proximity.

All these type of infections can get spread by hands because we cough on them, sneeze on them etc then touch surfaces. Worst surfaces are supermarket trolleys and grab rails on public transport, door handles etc. Next person along touches the same surface and transfers the virus to their own hands, then onto their food etc or just breathes it in off their own hands etc. |

As said, a case in Hong Kong where it is believed to have travelled upwards through a soil/ smell pipe in a high rise

Public 'pull or push' surfaces are primary transfer agents. Supermarket trolley handles and baby seats are about the worst as - like money- theyre never cleaned.
ATM,phones,ticket machines and computer keyboards, are other bad transfer agents.
If the aerosolisation transfer theory proves correct then theres pretty much nothing you do will guarantee you stay free of it.
Best defence is stay away from people especially in enclosed spaces
