Genomewide Association Study of Severe Covid-19 with Respiratory Failure

Study shows that people with Type A blood have a higher risk of catching coronavirus and of developing severe symptoms, while people with Type O blood have a lower risk. People with Type A blood had a 45% higher risk of becoming infected than people with other blood types, and people with Type O blood were just 65% as likely to become infected as people with other blood types.

Coronavirus testing indicates transmission risk increases along wildlife supply chains for human consumption in Viet Nam

Study shows that field rats sold in markets and restaurants of Southeast Asia harbour multiple coronaviruses, a study shows. The proportion of positives increased as live animals were moved from “field to fork”, suggesting they were picking up viruses in the process. The strains detected are different from Covid-19 and are not thought to be dangerous to human health. However, scientists have warned that the wildlife trade is an incubator for disease. The mixing of multiple coronaviruses, and their amplification along the supply chain into restaurants, suggests “maximal risk for end consumers”.

Rationing social contact during the COVID-19 pandemic: Transmission risk and social benefits

The study identifies the businesses that have the best overall risk-benefit profiles when weighing important factors such as essential value to shoppers and the economy, as well as the relative risk of contracting COVID-19—or as one researcher put it, which businesses give us the most bang for our buck. At the top of the pile are banks, which are economically important yet uncrowded and visited infrequently.

Identifying airborne transmission as the dominant route for the spread of COVID-19

A comprehensive study shows wearing masks significantly reduces the number of infections, far more than other measures such as social distancing. It shows that airborne transmission is highly virulent and dominates the spread of COVID-19. It reveals that the difference with and without masks represents the determinant in shaping the trends of the pandemic.

Governance, technology and citizen behavior in pandemic: Lessons from COVID-19 in East Asia

This paper analyzes the responses in East Asian countries and provides some commonalities and lessons. While countries have different governance mechanisms, it was found that a few governance decisions in respective countries made a difference, along with strong community solidarity and community behavior. Although the pandemic was a global one, its responses were local, depending on the local governance, socio-economic, and cultural context.

The effect of travel restrictions on the spread of the 2019 novel coronavirus (COVID-19) outbreak

Paper published in Science looks at how travel and quarantine influence the dynamics of the spread of COVID-19. It concludes that the travel quarantine introduced in Wuhan on 23 January 2020 only delayed epidemic progression by 3 to 5 days within China, but international travel restrictions did help to slow spread elsewhere in the world until mid-February. The results suggest that early detection, hand washing, self-isolation, and household quarantine will likely be more effective than travel restrictions at mitigating this pandemic.

Selection of viral variants during persistent infection of insectivorous bat cells with Coronavirus

New paper shows that when exposed to the MERS Coronavirus (CoV)  bat cells adapt—not by producing inflammation-causing proteins but rather by maintaining a natural antiviral response. Simultaneously, the MERS virus also adapts to the bat host cells by very rapidly mutating one specific gene. Operating together, these adaptations result in the virus remaining long-term in the bat but being rendered harmless. Instead of killing bat cells as the virus does with human cells, the MERS coronavirus enters a long-term relationship with the host, maintained by the bat’s unique ‘super’ immune system. SARS-CoV-2 is thought to operate in the same way. The work suggests that stresses on bats—such as wet markets, other diseases, and possibly habitat loss—may have a role in coronavirus spilling over to other species.

Effect of Alert Level 4 on Reff : review of international COVID-19 cases

This study mapped the coronavirus epidemic curve for 25 countries and modeled how the spread of the virus has changed in response to the various lockdown measures. It classifies each country’s public health response using New Zealand’s four alert system. Levels 1 and 2 represent relatively relaxed controls, whereas levels 3 and 4 are stricter. By mapping the change in the effective reproduction number (Reff, an indicator of the actual spread of the virus in the community) against response measures, the research shows countries that implemented level 3 and 4 restrictions sooner had greater success in pushing Reff to below 1.

Stopping Deforestation Can Prevent Pandemics – Scientific American

This article in Scientific American points out that three-quarters of the emerging pathogens that infect humans leaped from animals, many of the creatures in the forest habitats that we are slashing and burning to create land for crops, including biofuel plants, and for mining and housing. The more we clear, the more we come into contact with wildlife that carries microbes well suited to kill us—and the more we concentrate those animals in smaller areas where they can swap infectious microbes, raising the chances of novel strains.

CIDRAP report COVID-19 to spread up to 2 years

The new coronavirus is likely to keep spreading for at least another 18 months to two years—until 60% to 70% of the population has been infected, says a new report. The primary focus of these scenarios is on the Northern Hemisphere, but similar patterns could occur in the Global South, as well. The lack of robust healthcare infrastructure and comorbidities such as other infections, malnutrition, and chronic respiratory disease in certain areas of the Global South could result in the pandemic being even more severe in those areas, as was noted during the 1918-19 pandemic.

Misinformation During a Pandemic leads to negative health outcomes

A novel study looking at impacts of coverage of COVID-19 by two Fox News shows in the United States – Hannity and Tucker Carlson Tonight – on viewers’ behavior and downstream health outcomes. Carlson warned viewers about the threat posed by the coronavirus from early February, while Hannity originally dismissed the risks associated with the virus before gradually adjusting his position starting late February.  Hannity’s viewers changed behavior in response to the virus later than other Fox News viewers, while Carlson’s viewers changed behavior earlier. Greater viewership of Hannity relative to Tucker Carlson Tonight is strongly associated with a greater number of COVID-19 cases and deaths in the early stages of the pandemic.  The researchers say that provision of misinformation in the early stages of a pandemic can have important consequences for how a disease ultimately affects the population.

When Confronting a Pandemic, We Must Save Nature to Save Ourselves

This is a well-written statement entitled “When Confronting a Pandemic, We Must Save Nature to Save Ourselves” from the Centre for American Progress. The statement says COVID-19 outbreak has laid bare the need for a more proactive and integrated approach to fight infectious disease epidemics, which are becoming more common in many regions around the world. Specifically, we need to address the problem at its root: the destruction of nature. Nature is connected to human health, from the inherent mechanisms through which ecosystems regulate the emergence of new pathogens to the health benefits of spending time outdoors. But in our destruction of earth’s natural resources, we are losing these free services and reducing our resilience to new diseases.

Outcomes of hydroxychloroquine usage in United States veterans hospitalized with Covid-19

A pre-print of the results of a study of 386 coronavirus patients in a US government hospital for military veterans found more deaths among those treated with hydroxychloroquine than those treated with standard care. These findings highlight the importance of awaiting the results of ongoing prospective, randomized, controlled studies before widespread adoption of this drug, say the authors of the study.

Phylogenetic network analysis of SARS-CoV-2 genomes

New important research shows early ‘evolutionary paths’ of COVID-19 in humans – as the infection spread from Wuhan out to Europe and North America – using genetic network techniques. The research revealed three distinct ‘variants’ of COVID-19, consisting of clusters of closely related lineages, which they label ‘A’, ‘B’ and ‘C’. Variant ‘A’, most closely related to the virus found in both bats and pangolins, is described as ‘the root of the outbreak’. Type ‘B’ is derived from ‘A’, separated by two mutations, then ‘C’ is in turn a “daughter” of ‘B’.

Model quantifies the impact of quarantine measures on Covid-19’s spread

MIT has developed a model to determine the efficacy of quarantine measures and better predict the spread of the virus. The model found that in places where strong measures were implemented quickly, the quarantine effort could effectively curb the spread of the virus. In places where the quarantine efforts were rolled out slowly, the effort to slow the spread has been less effective. The model predicts when the coronavirus ‘plateau’ will take place, finding that the cases aren’t likely to start stagnating until some time between April 15 and April 20. It says that restrictions on quarantine can only be made when multiple conditions are met, including when the transmission is controlled, hospitals have capacities to meet all the needs of the public, workplaces have effective preventative measures in place, and more.

Sub-Saharan Africa Regional Economic Outlook

The International Monetary Fund (IMF) has released its Economic Outlook for Sub-Saharan Africa. The health crisis has precipitated an economic crisis reflecting three large shocks: disruption of production and a sharp reduction in demand; spillovers from a sharp deterioration in global growth and tighter financial conditions; and a severe decline in commodity prices. As a result, the region’s economy is projected to contract by 1.6 percent this year—the worst-reading on record. Some economies such as this highly dependent on tourism are expected to shrink further.

Determining the optimal duration of the COVID- 19 suppression policy: A cost-benefit analysis

The paper published on March 27 by the American Enterprise Institute compared the economic costs of businesses staying closed, which causes a steep drop in the gross domestic product, with the economic benefits of a lockdown. The research found that for at least two more months, the economic benefits of controlling the virus and preventing illness and death are greater than the economic cost of closing most non-essential businesses. It also found that even after the lockdown is lifted, we must keep in place more moderate measures, such as wearing face masks and limiting public gatherings, until a vaccine or an effective drug or treatment becomes widely available.

Extreme genomic CpG deficiency in SARS-CoV-2 and evasion of host antiviral defense

New genetic analysis of SARS-CoV-2 and related coronaviruses suggests the ancestor of COVID-19 and its nearest relative — a bat coronavirus — infected the intestine of dogs, most likely resulting in a rapid evolution of the virus and its jump into humans. This suggests the importance of monitoring SARS-like coronaviruses in feral dogs. It is to be noted however that other experts have doubts.

The paper projects that the US may have to endure social distancing measures — such as stay-at-home orders and school closures — until 2022, unless critical care capacity is increased substantially or treatment or vaccine becomes available. Another round of the virus is possible once social distancing measures are lifted. Even in the event of apparent elimination, SARS-CoV-2 surveillance should be maintained since a resurgence in contagion could be possible as late as 2024.

Global shifts in mammalian population trends reveal key predictors of virus spillover risk

Paper shows that wild mammals that were at risk of extinction owing to human activities carried twice the zoonotic diseases compared to animals that were not at the same risk. Among threatened wildlife species, those with population reductions owing to exploitation and loss of habitat shared more viruses with humans. This has increased opportunities for animal-human interactions and facilitated zoonotic-disease transmission.

Effect of non-pharmaceutical interventions for containing the COVID-19 outbreak in China

Study shows that by the end of February 2020 without non-pharmaceutical interventions (NPIs) in China– such as early detection, isolation of cases and social distancing – the number of infected people would have been 67 times larger than that which occurred. If NPIs could have been conducted one week, two weeks, or three weeks earlier in China, cases could have been reduced by 66%, 86%, and 95%, respectively, together with significantly reducing the number of affected areas. Improved disease detection, isolation of cases and social distancing are likely to a far greater positive impact on containment than travel restrictions, says the study.

How does COVID-19 kill? Uncertainty is hampering doctors’ ability to choose treatments

How does COVID-19 kill? Uncertainty over whether it is the virus itself — or the response by a person’s immune system — that ultimately overwhelms a patient’s organs, is making it difficult for doctors to determine the best way to treat patients who are critically ill with the coronavirus. Clinical data suggest that the immune system plays a part in the decline and death of people infected with the new coronavirus, and this has spurred a push for treatments such as steroids that rein in that immune response. But some of these treatments act broadly to suppress the immune system.

Rational use of face masks in the COVID-19 pandemic

Comparison of face mask use recommendations by different health authorities. Despite the consistency in the recommendation that symptomatic individuals and those in health-care settings should use face masks, differences in recommendations were observed for the general public and community settings. Evidence that face masks can provide effective protection against respiratory infections in the community is scarce. However, face masks are widely used by medical workers as part of droplet precautions when caring for patients with respiratory infections. The study suggests vulnerable individuals avoid crowded areas and use surgical face masks rationally when exposed to high-risk areas.

Identifying SARS-CoV-2 related coronaviruses in Malayan pangolins

A new paper, 26 March, describes multiple lineages of pangolin coronavirus and their similarity to the SARS-CoV-2. A previous study had suggested that Pangolins could be intermediate hosts.  Although bats are likely reservoir hosts for SARS-CoV-2, this study says that pangolins should be considered as possible hosts in the emergence of novel coronaviruses and should be removed from wet markets to prevent zoonotic transmission. The study was done on Malayan pangolins (Manis javanica) seized in anti-smuggling operations in southern China. Pangolins are the world’s most trafficked animals.

The SARS, MERS and novel coronavirus (COVID-19) epidemics, the newest and biggest global health threats: what lessons have we learned?

This paper finds that Inadequate risk assessment regarding the urgency of the situation, and limited reporting on the virus within China has, in part, led to the rapid spread of COVID-19. Compared with SARS and MERS, COVID-19 has spread more rapidly, due in part to increased globalization and the focus of the epidemic. The conclusion is that we did not learn from the two prior epidemics of coronavirus and were ill-prepared to deal with the challenges the COVID-19 epidemic has posed. Future research should attempt to address the uses and implications of the internet of things (IoT) technologies for mapping the spread of infection.

We shouldn’t worry when a virus mutates during disease outbreaks

Mutation. The word naturally conjures fears of unexpected and freakish changes. Ill-informed discussions of mutations thrive during virus outbreaks, including the ongoing spread of SARS-CoV-2. In reality, mutations are a natural part of the virus life cycle and rarely impact outbreaks dramatically say virologists writing in the journal Nature Microbiology.

Are viruses alive?

 Viruses are kind of mysterious – there is debate on whether on not they are “alive”.  At a basic level, viruses are proteins and genetic material that survive and replicate within their environment, inside another life form. In the absence of their host, viruses are unable to replicate and many are unable to survive for long outside the host. Therefore, if they cannot survive independently, can they be defined as being ‘alive’? Taking opposing views, two microbiologists discuss how viruses fit with the concept of being ‘alive’ and how they should be defined.

WHO launches global megatrial of the four most promising coronavirus treatments

An article from the publishers of Science on 22 March on WHO megatrials. WHO is focusing on what it says are the four most promising therapies: an experimental antiviral compound called remdesivir; the malaria medications chloroquine and hydroxychloroquine; a combination of two HIV drugs, lopinavir, and ritonavir; and that same combination plus interferon-beta, an immune system messenger that can help cripple viruses.

Twitter thread on Chloroquine (CQ) and Hydroxychloroquine (HCQ) by Dr. Gaetan Burgio

Unusually, we include a Twitter feed here as it represents a good analysis of the efficacy of the antimalarial drug chloroquine as a treatment for COVID-19. It is from Dr. Gaetan Burgio, a geneticist at the Australian National University who dug into the available & published data and reveals that as of this date the evidence remains anecdotal and a clinical trial is incomplete and not following scientific rigour. More research is needed.
