It was the details revealed by Dr Li Wenliang before he died which concerned me.
In his Weibo post he describes how on 10 January he started coughing, the next day he had a fever and two days later he was in hospital. His parents also fell ill and were taken to hospital.
Dr Li says he was tested several times for coronavirus, all of them came back negative.
On 30 January he posted again: "Today nucleic acid testing came back with a positive result, the dust has settled, finally diagnosed."
Do the math. 30 - 10 = 20 Twenty days before his infection was confirmed as Covid-19 which is nearly a week longer than the quarantine time we are following. Not everyone, as shown by "patient zero" gets really sick, some just have a passing cough or nothing at all. Which logically means there could be people with it totally un - diagnosed but spreading it to others.
Healthy people have a tendency to socialise with other healthy people, tis sociology, and sicker people tend to be around other sicker people i.e elderly in homes for the elderly. Hence in the initial weeks, the majority of victims have been the elderly and the sick as they get ill easiest and have less opportunity to avoid the contagion.
All of a sudden as we move into the third month of the virus, we might see many more fitter people falling ill over a greater geographical area. The first official death was on or about 14th Dec. A week later the toll is 6 people. Another week it's 106. Another week later and it's 565 (figures scoured from sites including BBC and cross referenced but still prone to slight inaccuracy)
Herd immunity is about giving those who cannot due to age i.e babies have vaccinations yet but who would suffer severe consequences. I suspect that last Sunday's "Call the Midwife" was a shot across the bow of the anti vaxxers, with the death of a newly born baby from complications congenital rubella syndrome.
I see both sides of the argument. If the lifes of babies can be saved by vaccinating older children and adults then why not, but also I understand the concern anti vaxxers have about the alleged contaminants and additives in vaccine. There is credible evidence that aluminium for instance is a possible cause of some types of senile dementia. Therefore the government really should step in and have a through review of the manufacture of vaccines. If there is no basis for the concerns then let it be known, rather than simply brow beat those campaigning against such vaccines.
