Scrapping Covid surveillance study would put public health at risk [by Silvia Richardson]

Royal Statistical Society president (and very dear friend) Sylvia Richardson published this tribune in the Guardian defending the preservation of a national surveillance system last week:

Sajid Javid is right to argue against scrapping the Office for National Statistics’ Covid surveillance study. Throughout the pandemic, national surveillance studies have provided invaluable information to support decision-making.

For any real-time health surveillance system to be reliable and cost-effective, it cannot rely solely on self-reported tests. These data sets are likely to be biased, as it is impossible to know how many people are also reporting their negative results and, if tests start to come with a cost, how many people simply aren’t testing. If we are to get reliable information about the prevalence of Covid, it is essential to maintain studies such as the ONS’s and React to allow statisticians to estimate infectiousness and the proportion of the population who are infected (including those without symptoms), as well as to identify new variants.

Abrupt disruption of a surveillance system is wasteful, will make tracking of prevalence meaningless and will put in jeopardy the future health of the public. If important surveillance studies must be scaled down, this cannot be led by arbitrary cost-cutting targets, but should be led by statisticians to ensure that studies continue to provide reliable information.

In the latest Significance, there was a flyer with some members updates, an important one being that Sylvia Richardson had been elected the next president of the Royal Statistical Society. Congratulations to my friend Sylvia! Another item was that the publication of the 2018 RSS Statistic of the Year has led an Australian water company to switch from plastic to aluminum. Hmm, what about switching to nothing and supporting a use-your-own bottle approach? While it is correct that aluminum cans can be 100% made of recycled aluminum, this water company does not seem to appear to make any concerted effort to ensure its can are made of recycled aluminum or to increase the recycling rate for aluminum in Australia towards achieving those of Brazil (92%) or Japan (86%). (Another shocking statistic that could have been added to the 90.5% non-recycled plastic waste [in the World?] is that a water bottle consumes the equivalent of one-fourth of its contents in oil to produce.) Another US water company still promotes water bottles as one of the most effective and inert carbon capture & sequestration methods”..! There is no boundary for green-washing.
