Pictures of crowded election rallies in Bihar (the final stage of polling is on Saturday) have brought on concern in some quarters a couple of spike in coronavirus illness instances within the state.
Such concern is misplaced.
In line with the HT dashboard, Bihar had a mere 7,001 energetic instances of Covid-19 on Tuesday evening. On Tuesday, the state registered simply 846 instances from the 143,642 assessments it carried out. That interprets to a positivity fee of zero.6%. The cumulative positivity fee of the state is 1.9% (it carried out 11.33 million assessments until Tuesday night and registered 218,964 instances). And it has a case fatality fee of zero.5%.
These are numbers of which Germany, a rustic broadly acknowledged with managing the pandemic nicely — largely on the energy of aggressive testing and its legacy investments in hospital infrastructure — can be proud (Bihar’s numbers are rather a lot higher than Germany’s, you see).

Bihar’s inhabitants, at 125 million, is round 50% increased than Germany’s 83 million. It’s also 25 occasions New Zealand’s inhabitants. That island nation’s cumulative positivity fee is zero.17%.
I’ve written beforehand in regards to the thriller of Uttar Pradesh’s numbers, and the way that is much like the thriller of Africa’s (which has additionally seen disproportionately few instances and fewer deaths than most components of the world).
It’s a thriller that’s led to some attention-grabbing hypotheses, resembling this: “The mortality as a consequence of Covid-19 in numerous nations is related to the demographic character of countries and the prevalence of autoimmunity.” That’s a paper by Bithika Chatterjee, Rajeeva Laxman Karandikar and Shekhar C Mande, revealed on the pre-print server medRxiv. The authors are from CSIR, Nationwide Centre for Cell Sciences, and Chennai Mathematical Institute. The paper, revealed in mid-October and never peer reviewed but, means that the explanation for this thriller might be the so-called “hygiene speculation”.
“The speculation postulates that publicity to pathogens early in life protects folks from allergic ailments later of their lives. Furthermore, enchancment in hygiene practices resembling higher sanitation, availability of secure consuming water, hand washing services and so forth. reduces the influence of communicable ailments. Quite the opposite, such a discount to the publicity to infectious brokers could be associated to increased prevalence of autoimmune problems,” the authors write.

They picked “GDP, HDI, prevalence of assorted ailments, demographic parameters, varied sanitation parameters”, demographic information, the administration of the BCG vaccine, and measured the correlation between these and the case fatality fee to show their speculation. With the previous caveat that correlation doesn’t imply causation, I imagine that is an attention-grabbing examine that deserves additional exploration, together with area research (the authors based mostly their paper on secondary analysis utilizing revealed information).
It’s shocking that India’s federal well being ministry or the Indian Council of Medical Analysis haven’t thought the achievements of Bihar and UP in managing the pandemic worthy of nearer examine. In any case, why look to Germany or New Zealand as benchmarks when you’ve gotten native ones (that you could be vocal about).
Each Bihar and Uttar Pradesh predominantly use fast antigen assessments, that are unreliable. A New York Instances report stated on November 2 that one well-liked fast antigen take a look at (Sofia, made by Quidel) recognized solely “32% of optimistic instances recognized by the” extra correct reverse transcription polymerase chain response (RT-PCR take a look at). Different research have proven that fast antigen assessments miss round half the optimistic instances (though some corporations, together with Abbott Laboratories, have launched what they declare are correct fast antigen assessments). However the numbers in these states are far too low, even when one had been to account for using such assessments.
