A focus on the systematic monitoring of G20 country policy responses to Covid-19 facilitates better understanding of the extent to which they have supported health equity globally and where they fall short and highlights actions G20 countries can take to place equity at the front and centre of recovery efforts.
Any efforts to construct a composite index must consider carefully how to treat the indicators, weight indicators and dimensions, and aggregate the data; the brief outlines options and their implications.
Efforts to monitor G20’s Covid-19 response are beset by limitations, not least the absence of indicators on actions no member country has taken, such as compelling pharmaceutical companies to share vaccines, knowledge and patents with poorer countries.
The available data reveals huge variation in G20 country performance, irrespective of their incomes, and between what countries have done and what they could have done to advance equity. Rand [to 09 Apr 2022] https://www.rand.org/pubs.html Reports, Selected Journal Articles

Key updates On 24 March WHO started the establishment of a logistics hub in the city of Dnipro in collaboration with the United Nations High Commissioner for Refugees (UNHCR), the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) and other United Nations (UN) partners, to facilitate the delivery of medical supplies and humanitarian assistance to areas in eastern Ukraine most severely affected by the ongoing conflict. WHO has developed tools to estimate the need for antiviral treatment and burden of tuberculosis (TB) among refugees from Ukraine to other countries. Both these tools are meant to support resource planning for the refugee-hosting countries. Based on the preliminary estimates, more than 30 000 people living with HIV may need HIV services in refugee-hosting countries. In Poland WHO conducted a joint mission to assess the availability and accessibility of health services in the border region of Lublin on 25–26 March. In the Republic of Moldova, WHO and the MoH conducted a rapid assessment of the health services available to refugees on 27 March…

This number has dropped significantly, with only 175 000 people being vaccinated between 24 February and 15 March despite suboptimal vaccination coverage. Between 23 February and 30 March, the overall number of beds available and beds occupied by patients with COVID-19 has decreased by 29% and 85% respectively, reflecting potential challenges in accessing hospitals, limited data reporting, and a potential decrease in actual hospitalizations following the peak of the Omicron wave earlier in February…

Volume 376| Issue 6588| 1 Apr 2022 https://www.science.org/toc/science/current Special issue – Completing the human genome
Introduction to Special Issue Filling the gaps
BY Laura M. Zahn
31 Mar 2022: 42-43
A fully sequenced human genome was triumphantly announced more than 20 years ago. However, owing to technological limitations, some genomic regions remained unresolved. Here, Science presents research by the Telomere-to-Telomere (T2T) Consortium, reporting on the endeavor to complete a comprehensive human reference genome. Generated primarily by long-read sequencing of a hydatidiform mole, a doubly haploid growth, this effort adds ∼200 megabases of genetic information—a full chromosome’s worth—to the human genome.
Through the resolution of previously unsequenceable and unalignable regions, mostly composed of highly repetitive sequences, this reference genome allows for a detailed characterization of the centromeric satellite repeats, transposable elements, and segmental duplications. Mapping of genomic sequences, including those from previously published studies, resolves aspects of human genetic diversity, including evolutionary comparisons with our primate relatives. Furthermore, it allows for identification of how changes in methylation density differ within and among centromeres and how epigenetics can affect the transcription of repeat sequences.
These investigations have only begun to tease apart how the T2T reference genome influences the detection of biomedically relevant variants and the evolution of genomic regions that determine human traits. Although much remains to be discovered, the T2T reference genome provides another celebratory benchmark to observe as we continue to delve into the genetics that underlie our complete selves.//
The complete sequence of a human genome
BY Sergey Nurk et al [89 authors]
31 Mar 2022: 44-53 Abstract
Since its initial release in 2000, the human reference genome has covered only the euchromatic fraction of the genome, leaving important heterochromatic regions unfinished. Addressing the remaining 8% of the genome, the Telomere-to-Telomere (T2T) Consortium presents a complete 3.055 billion–base pair sequence of a human genome, T2T-CHM13, that includes gapless assemblies for all chromosomes except Y, corrects errors in the prior references, and introduces nearly 200 million base pairs of sequence containing 1956 gene predictions, 99 of which are predicted to be protein coding. The completed regions include all centromeric satellite arrays, recent segmental duplications, and the short arms of all five acrocentric chromosomes, unlocking these complex regions of the genome to variational and functional studies.

NIH – Researchers generate the first complete, gapless sequence of a human genome – Completion is critical for understanding the full spectrum of human genomic variation and for understanding the genetic contributions to certain diseases.
March 31, 2022 — Scientists have published the first complete, gapless sequence of a human genome, two decades after the Human Genome Project produced the first draft human genome sequence.
According to researchers, having a complete, gap-free sequence of the roughly 3 billion bases (or “letters”) in our DNA is critical for understanding the full spectrum of human genomic variation and for understanding the genetic contributions to certain diseases. The work was done by the Telomere to Telomere (T2T) consortium, which included leadership from researchers at the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health; University of California, Santa Cruz; and University of Washington, Seattle. NHGRI was the primary funder of the study.
Analyses of the complete genome sequence will significantly add to our knowledge of chromosomes, including more accurate maps for five chromosome arms, which opens new lines of research. This helps answer basic biology questions about how chromosomes properly segregate and divide. The T2T consortium used the now-complete genome sequence as a reference to discover more than 2 million additional variants in the human genome. These studies provide more accurate information about the genomic variants within 622 medically relevant genes.
“Generating a truly complete human genome sequence represents an incredible scientific achievement, providing the first comprehensive view of our DNA blueprint,” said Eric Green, M.D., Ph.D., director of NHGRI. “This foundational information will strengthen the many ongoing efforts to understand all the functional nuances of the human genome, which in turn will empower genetic studies of human disease.”… The full sequencing builds upon the work of the Human Genome Project, which mapped about 92% of the genome, and research undertaken since then. Thousands of researchers have developed better laboratory tools, computational methods and strategic approaches to decipher the complex sequence. Six papers encompassing the completed sequence appear in Science(link is external), along with companion papers in several other journals. That last 8% includes numerous genes and repetitive DNA and is comparable in size to an entire chromosome. Researchers generated the complete genome sequence using a special cell line that has two identical copies of each chromosome, unlike most human cells, which carry two slightly different copies. The researchers noted that most of the newly added DNA sequences were near the repetitive telomeres (long, trailing ends of each chromosome) and centromeres (dense middle sections of each chromosome).
“Ever since we had the first draft human genome sequence, determining the exact sequence of complex genomic regions has been challenging,” said Evan Eichler, Ph.D., researcher at the University of Washington School of Medicine and T2T consortium co-chair. “I am thrilled that we got the job done. The complete blueprint is going to revolutionize the way we think about human genomic variation, disease and evolution.”…
According to consortium co-chair Adam Phillippy, Ph.D., whose research group at NHGRI led the finishing effort, sequencing a person’s entire genome should get less expensive and more straightforward in the coming years.
“In the future, when someone has their genome sequenced, we will be able to identify all of the variants in their DNA and use that information to better guide their healthcare,” Phillippy said. “Truly finishing the human genome sequence was like putting on a new pair of glasses. Now that we can clearly see everything, we are one step closer to understanding what it all means.” Many early-career researchers and trainees played pivotal roles, including researchers from Johns Hopkins University, Baltimore; University of Connecticut, Storrs; University of California, Davis; Howard Hughes Medical Institute, Chevy Chase, Maryland; and the National Institute of Standards and Technology, Gaithersburg, Maryland. The package of six papers reporting this accomplishment appears in today’s issue of Science, along with companion papers in several other journals.

WHO releases 10-year strategy for genomic surveillance of pathogens One in three countries do not have the capacity to use this critical tool
30 March 2022 News release
…Genomic surveillance is the process of constantly monitoring pathogens and analyzing their genetic similarities and differences. It helps researchers, epidemiologists and public health officials to monitor the evolution of infectious diseases agents, alert on the spread of pathogens, and develop counter measures like vaccines.
Data collected by WHO show that in March 2021, 54% of countries had this capacity. By January 2022, thanks to the major investments made during the COVID-19 pandemic, the number had increased to 68%. Even greater gains were made in the public sharing of sequence data: in January 2022, 43% more countries published their sequence data compared to a year before.
Despite this fast progress, much remains to be done. Any new technology comes with the risk of increasing inequity, which is one of the gaps this strategy targets. Various public health programmes – from Ebola to cholera – use genomic surveillance to understand a pathogen at its molecular level, but COVID-19 has highlighted the challenges of bringing genomics to scale.
Dr Tedros Adhanom Ghebreyesus, WHO Director-General, said, “The complexities of genomics and the challenges of sustaining capacities in different settings, including workforce needs, means that most countries cannot develop these capabilities on their own. The global strategy helps keep our eyes on the horizon and provides a unifying framework for action. WHO looks forward to working with countries and partners in this important and highly dynamic field,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. “We will do best if we work together.”…
Global genomic surveillance strategy for pathogens with pandemic and epidemic potential, 2022–2032 [WHO]
28 March 2022 32 pages
The Strategy provides a high-level unifying framework to leverage existing capacities, address barriers and strengthen the use of genomic surveillance in the detection, monitoring and response to public health threats. Genomic surveillance is part of the broader surveillance and laboratory system, and its implementation should reinforce end-to-end capacities including sample collection, diagnostics, data sharing and analysis. The strategy aims to facilitate the connectivity between different disease control programs and surveillance networks. This interoperability will strengthen the cross-cutting essential public health laboratory functions underpinning genomics holistically. The strategy articulates the overarching goal, objectives and strategic actions needed. These are dependent on commitments from countries, partners and WHO for their implementation.
A herd immunity threshold is the proportion of a population with immunity against a communicable disease agent (resulting from innate immunity, natural infection, or vaccination) above which transmission of the agent is largely prevented, except for sporadic outbreaks in under-vaccinated or otherwise incompletely protected subsets of individuals.
As commonly understood [1-7], herd immunity thresholds are reached when a sufficient proportion of the population is vaccinated or has recovered from natural infection with a pathogen such that its community circulation is reduced below the level of significant public health threat. For example, this threshold has been met with polio and measles circulation in the United States.
However, SARS-CoV-2, the virus that causes COVID-19, is so different from polio and measles that classical herd immunity may not readily apply to it. Important differences include the phenotypic stability of polio and measles viruses, and their ability to elicit long-term protective immunity, compared to SARS-CoV-2. For these and other reasons, controlling COVID-19 by increasing herd immunity may be an elusive goal…
[Closing Section] HERD IMMUNITY AND COVID-19. There are significant obstacles to achieving complete herd immunity with COVID-19. “Classical” herd immunity, leading to disease eradication or elimination, almost certainly is an unattainable goal. As noted, mass vaccination and aggressive public health approaches have struggled to control other (seemingly more controllable) respiratory infectious diseases, such as smallpox, measles, and rubella, all caused by viruses with limited phenotypic evolution. Controlling SARS-CoV-2 and its cycles of new variants presents a much more formidable challenge *23+. Like influenza, SARS-CoV-2 mutates continually into new variants that can escape immunity derived from infections and vaccines. It also can be transmitted asymptomatically and without pathognomonic signs, impeding public health control. SARS-CoV-2 appears not to substantially engage the systemic immune system, as do viruses such as smallpox, measles, and rubella that consistently have a pronounced viremic phase. Moreover, neither infection nor vaccination appears to induce prolonged protection against SARS-CoV-2 in many or most people. Finally, the public health community has encountered substantial resistance to efforts to control the spread of SARS-CoV-2 by vaccination, mask wearing, and other interventions.
If vaccine- or infection-induced immunity to SARS-CoV-2 indeed proves to be short-lived, or if escape mutants continue to emerge, viral spread may continue indefinitely, albeit hopefully at a low endemic level. This notably has occurred with the 1918 pandemic influenza virus, whose viral descendants still are causing seasonal outbreaks and occasional pandemics 104 years later (pandemic H2N2 in 1957, H3N2 in 1968, and H1N1 in 2009) (24), and which we have been unable, after more than 80 years of trying, to fully control with vaccines. Such factors probably make SARS-CoV-2 impossible to eradicate (only one human virus – smallpox — has ever been eradicated), difficult to eliminate over long periods within large geographic areas, and difficult to satisfactorily control even with good vaccines.
Thus, COVID-19 is likely to be with us, even if at a very low level of endemic community spread and with lower severity, for the foreseeable future. Like influenza, any level of herd protection against SARS-CoV-2 potentially can be overcome by ever-changing levels of immunity among countless sub-populations, by human movement, crowding, changes in social or prevention behaviors, by demographics, by vaccination levels, by variations in durability of infection- or vaccine-induced immunity, and by evolution of viral variants, among many other variables.
But encouragingly, after more than two years of viral circulation, and more than a year of vaccines with boosters, we now have a high degree of background population immunity to SARS-CoV-2, as well as medical countermeasures such as antiviral drugs and monoclonal antibodies to prevent progression of disease, and widely available diagnostic tests. With these interventions we can aspire to, and very likely will succeed in achieving, substantial control of community spread without the disruptions of society caused by COVID-19 over the past 2 years. We no longer need the elusive concept of “herd immunity” as an aspirational goal: COVID-19 control is already within our grasp.
Looking forward, more broadly protective vaccines could play important roles in controlling SARS-CoV-2 and its inevitable variants. Developing “universal” coronavirus vaccines (or at least universal SARS-CoV-2 vaccines that elicit durable and broadly protective immunity against multiple SARS-CoV-2 variants) is an important goal for the immediate future (23). Meanwhile, optimal COVID-19 control will require both classic, non-pharmacologic public health approaches and vaccination of many more people globally with the SARS-CoV-2-specific vaccines we already have, with booster shots and with updates to vaccine antigens if needed.
Living with COVID is best considered not as reaching a numerical threshold of immunity, but as optimizing population protection without prohibitive restrictions on our daily lives. Effective tools for prevention and control of COVID-19 (vaccines, prevention measures) are available; if utilized, the road back to normality is achievable even without achieving classical herd immunity.
Weekly epidemiological update on COVID-19 – 29 March 2022 Overview Between the end of January and early March 2022, there was a consistent decreasing trend in the number of new COVID-19 cases, which was followed by two consecutive weeks of increase in cases. During the week of 21 through 27 March 2022, the number of new cases declined again with a 14% decrease as compared to the previous week. On the other hand, during the same period, the number of new weekly deaths has increased by 43%, driven by changes in the definition of COVID-19 deaths in countries in the Region of the Americas (Chile and the United States of America) and retrospective adjustments reported from India in the South-East Asia Region.
Across the six WHO regions, over 10 million new cases and over 45 000 new deaths were reported. All regions reported decreasing trends in the number of new weekly cases and four regions reported a decreasing trend in new weekly deaths. As of 27 March 2022, over 479 million confirmed cases and over 6 million deaths have been reported globally.
In this edition, we provide updates on the geographic distribution of circulating SARS-CoV-2 variants of concern (VOCs), including information on recombinant variants.

This week, two humanitarian convoys from U.S. Agency for International Development (USAID) partner UN World Food Program (WFP) transported emergency food aid to the Tigray and Afar regions of northern Ethiopia, including the first convoy to Tigray in more than three and a half months. This emergency food aid will support more than 100,000 people in northern Ethiopia. The arrival of the convoys is an important development in the effort to provide life-saving assistance to the people of Tigray and Afar, as only road transport can deliver the scale of assistance needed across northern Ethiopia. USAID commends the federal and regional Ethiopian authorities, as well as local communities, which worked together to make this first step possible. USAID urges all parties to ensure sustained and significant access for the delivery of life-saving assistance in these regions, as well as the neighboring Amhara region.

Entire Shanghai Placed Under Lockdown City reported more than 6,300 new Covid infections Friday Eastern half of city remains under tight restrictions Bloomberg News. April 1, 2022, 10:43 PM EDT Updated onApril 2, 2022, 6:44 AM EDT
Shanghai’s 25 million residents are almost all under some form of lockdown as the financial hub struggles to contain the coronavirus’s highly contagious omicron variant.
The eastern half of the mega Chinese city remains under tight movement restrictions despite the end of a four-day sweeping lockdown Friday morning, according to a government statement Saturday. That means the entire population of the metropolis is currently under some form of quarantine as the two-part lockdown shifted to the western half of Shanghai on Friday.
Residents in the western part of the city, where about two-thirds of its population live, began their four-day lockdown at 3 a.m. local time on Friday as the program approached an end in the east. During the restrictions, residents are barred from leaving home except for mandatory mass Covid tests…

Public hearings regarding a new international instrument on pandemic preparedness and response
12 – 13 April 2022
In a consensus decision aimed at protecting the world from future infectious diseases crises, in December 2021 the World Health Assembly agreed to kickstart a global process by establishing an intergovernmental negotiating body (INB) to draft and negotiate a convention, agreement or other international instrument under the Constitution of the World Health Organization to strengthen pandemic prevention, preparedness and response.
Dr Tedros Adhanom Ghebreyesus, WHO Director-General, said the decision by the World Health Assembly was historic in nature, vital in its mission, and represented a once-in-a-generation opportunity to strengthen the global health architecture to protect and promote the well-being of all people.
As part of this historic decision, the World Health Assembly requested the Director-General to hold public hearings, in line with standard WHO practice, to support the work of the INB. [Registration link not yet available]
28 March 2022 Global genomic surveillance strategy for pathogens with pandemic and epidemic potential, 2022–2032 [WHO] Overview
The Strategy provides a high-level unifying framework to leverage existing capacities, address barriers and strengthen the use of genomic surveillance in the detection, monitoring and response to public health threats. Genomic surveillance is part of the broader surveillance and laboratory system, and its implementation should reinforce end-to-end capacities including sample collection, diagnostics, data sharing and analysis. The strategy aims to facilitate the connectivity between different disease control programs and surveillance networks. This interoperability will strengthen the cross-cutting essential public health laboratory functions underpinning genomics holistically. The strategy articulates the overarching goal, objectives and strategic actions needed. These are dependent on commitments from countries, partners and WHO for their implementation.

Health Equity in US Latinx Communities
Latinx communities in the US include over 60 million people with a plurality of political beliefs, cultural practices, and wealth. This diversity is also expressed in population health data: some health indicators suggest advantages of Latinx community membership while other data demonstrate inequitable disease burden and maldistribution of environmental and occupational risk. Legacies of colonial conquest of the Americas persist in discrimination and marginalization today and are embodied by members of our Latinx communities.
