If a face mask was enough then would the authorities be approaching suspected infected people in the hazmat suits?
I read somewhere- but don't have the source to hand, that eyes & ears are points of entry, also the virus can survive a long while on surfaces.
So the only thing a mask is any use for is preventing the wearer from coughing or snotting droplets on others.
If the wearer has the virus and has touched their face & not properly washed their hands then a mask is not gonna stop transmission of lurgy.
However, keeping fit/ eating healthy foods such as fruit & veggies to boost the immune system, washing hands to the point of obsession (maybe that is just me) and maintaining decent hygiene should keep as many nasty bugs out of the head/facial zone as possible.
I am concerned that the jump in confirmed cases was more than 1500 in 24 hours but the incubation period may be part of the explanation.
The virus can sit around in the body for over 5 days (and up to 14 days if reports are accurate) before one shows symptoms- so I am cynical about the temperature reading devices at airports being effective.
Indeed looking at the global spread, one may assume the opposite (depending on when these temperature screenings were implemented).
I think my main take-away from all this , at this point would be: If you have elderly or infirm family members and come down with flu/like symptoms, best to keep your distance or practice stringent hygiene procedures as they are the ones who are at highest risk of fatality- from any type of flu.
& remember there have been 132 related deaths to date, in 2 months, all in mainland China.
So, why would one panic?
