Hello Don and Others,
as the ABC's Medical Reporter Dr Norman Swan has pointed out, a successful Covid-19 response means that not much appears to be happening, conversely, if a lot is happening, then the problem is getting worse. Hence, it is preferable if we all keep on our guard, wash our hands more often (**), limit travel to essential purposes, maintain social distancing, and other hygienic strategies until such time as the Covid-19 threat has been substantially reduced.
This could take a few years, yes, years, if we look at the misnamed Spanish 'Flu which predates 1919, and was still around, in diminished form, in 1921. Some studies intimate that it broke out in Kansas ( USA ) in 1916, but that also means that it was possibly starting to mutate in 1915.
(** You can wash your hands with sufficient time by singing Happy Birthday, or God Save the Queen ( German or English versions to taste ! ) or Queen's We will Rock You, take your choice. )
The uptake in 'flu shots should be encouraged as both the 'flu and Cover-19 have similar symptoms , and like pneumonia can develop from the 'flu, it is equally likely that the 'flu could make you more susceptible to Covid-19, so understandably, the Medical Authorities are encouraging people to get a 'flu shot.
I also note that the ABC News this evening made comments about the high risk poorly ventilated offices pose, which is also evident in the past when the 'flu spread though an office building rapidly.
Do not underestimate the ability of a virus to mutate, especially a virus that has shown an ability to infect people quickly. It is also to be noted that people who have recovered from Cold-19 spent 6 weeks + in hospital, and returned home in a weakened state, which some survivors has indicated this weekend state has lasted for months and they still do not feel as well as they were prior to hospitalisation.
Best wishes and regards to all, Radioman.
