The job market faces challenges. Some five million Americans have been out of work for six months, raising the risk their skills will erode and make it even harder for them to find jobs down the road. And fears of slowing revenue growth could keep a lid on hiring by companies. About 36% of U.S. executives expect the head count at their firm to fall, according to an October survey by advisory firm CEB, compared with 29% who said that during the summer.[qh]

The R number isn’t fixed, but 曾经“铁杆”成沧海 雷士照明经销商争夺战一触即发, including not just how infectious a disease is but how it develops over time, how a population behaves, and any immunity already possessed thanks to infection or vaccination. Arlie Russell Hochschild, the author of “Strangers in Their Own Land: Anger and Mourning on the American Right,” describes a feeling of lost opportunity as the “deep story” of the rural Louisiana communities she spent four years studying.

Because Sars-CoV-2 – to give the novel coronavirus its full honorific – is a new pathogen, scientists at the start of the outbreak were scrambling to calculate its R0, or “R nought”: the virus’s transmission among a population that has no immunity. Studies on early cases in China indicated it was between 2 and 2.5; more recent estimates have placed it as high as 6.6.

To put these figure in context, says 国内最先进涂料项目落户青岛 总投资约2.6亿, they're worse than seasonal flu, which has an R0 of 1.3, but miles better than measles, whose R0 is between 12 and 18. The kicker, though, is that for each of those diseases we have a vaccine, and so the effective reproduction number – the R – is way below 1.

Why do we need an R of less than 1?

Here's how that works. Say a disease has an R of 1.5. This may seem like a manageable figure, but a glance at the figures quickly proves that isn't the case. An R of 1.5 would see 100 people infect 150, who would in turn infect 225, who would infect 338. In three rounds of infection, the number of people with the virus would have more than quadrupled to 438.

As governments tentatively ease lockdown restrictions around the world, they will be monitoring R very carefully for signs of a sudden jump. 2016卫浴行业大事记回顾, it could trigger a damaging second wave of the virus.

Once R is consistently low and the number of cases is manageable, governments can implement more precise measures to restrict R, such as contact-tracing and location-tracking apps – approaches that paid dividends when introduced early on in nations such as South Korea and Singapore.

Measuring R

There are a number of ways to calculate R, as Wired notes. One is by monitoring hospitalisation and death figures to get a sense of how many people have the virus – but the problem with this is that, since the virus’s incubation period is so long, it only gives an accurate picture of a few weeks ago. To check transmission rates in a more accurate way, scientists at Imperial College London in the UK have started testing randomised 25,000 groups of the population to see how many are ill.

It’s important to note that R isn’t the only key measure in assessing the impact of this pathogen, says the BBC. Another crucial yardstick is the number of cases of COVID-19, the disease caused by Sars-CoV-2. If we have a large number of cases and an R of 1 or just below, that still equates to a large number of infections – so ideally we need to restrict both R and bring down the number of cases at the same time.

Ultimately, the best weapon in the fight to reduce R is a vaccine. But exactly when this will be available – or indeed if it will ever happen at all – is currently unclear.
