USA: All 50 U.S. States Have Now Started To Reopen, Easing COVID-19 Shutdown – NPR

The U.S. economy, frozen by COVID-19 shutdowns, is in the process of thawing out. All 50 states have at least partially eased tight restrictions on businesses, with a mix of policies letting restaurants or stores welcome customers. Just after midnight Wednesday, Connecticut became the final state to let business serve customers more directly than they have in weeks. The state is now allowing outdoor seating at restaurants, and non-essential retail stores and malls can also reopen.

Low white blood cell counts linked to severe COVID-19 cases – Modern Healthcare

Host factors rather than viral genetic differences appear to influence disease outcomes among COVID-19 patients, according to a new study from China. Researchers in Shanghai examined clinical, molecular, and immunological data from more than 300 people with confirmed COVID-19. While infection with SARS-CoV-2 can lead to severe respiratory disease and death, it also can result in more mild pneumonia in some patients. [Related Study]

COVID Narratives by Dr. David Nabarro

Across the world, the nations that are getting ahead of the virus know that economies and societies can thrive if they implement comprehensive action to keep it at bay. Yet, not all the nations represented at the Assembly are implementing the COVID-19 containment policies that have been continuously advocated by the World Health Organization (WHO) since late January 2020.

Tedros hails WHO ‘landmark resolution’ to accelerate COVID-19 response – UN

With “unprecedented solidarity”, the World Health Assembly adopted a “landmark resolution” on Tuesday, which sets out a “clear roadmap” of the actions needed to sustain and accelerate the COVID-19 response at both national and international levels, the UN health agency chief told a press briefing on Wednesday, the day after the meeting concluded.

As COVID-19 cases near 5 million, WHO sees long road ahead – CIDRAP

As cases neared 5 million today, the World Health Organization (WHO) director-general said that a record daily high of 106,000 cases were reported over the past day. And with worries rising about cases in low- and middle-income countries, there’s still a long road ahead with the pandemic.

What a Second Wave of Coronavirus in the Fall Could Look Like – Healthline

As temperatures and humidity levels rise, there are hopes that infection rates of the new coronavirus may drop in the spring and summer — following a similar seasonal pattern as the flu and common cold.

COVID-19 & PEPFAR: Implications for the Future – Kaiser Family Foundation

COVID-19 has the potential to deeply impact PEPFAR countries, especially those in sub-Saharan Africa and, as such, affect PEPFAR’s future trajectory.
As the largest U.S. global health program, PEPFAR is in a unique position to respond to COVID-19, but the outbreak also raises urgent new questions for PEPFAR, as well as underscores existing challenges.

Dutch farm worker contracted coronavirus from mink: agriculture minister – Reuters

A person who worked on a farm where mink are bred to export their fur contracted the coronavirus from the animals, the Dutch Agriculture Minister said in a letter to parliament on Wednesday.

Europe learning the dangers of going back to school after coronavirus – Politico

Europe has two problems when it comes to reopening schools. First, there’s weighing the risks of opening the gates again against the potential damage done by keeping them closed, whether to economic recovery or mental health. Even more challenging may be convincing anxious parents that now is the time to send their children back to school.

Science and Tech

Main receptors used by SARS-CoV-2 for cell entry are absent in the human placenta – Medical News

Although severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is unlikely to infect human placenta through the canonical cell entry mediators, Wayne State University researchers showed that other interacting proteins may still play an important role during the viral infection.

Nearly half of Twitter accounts pushing to reopen America may be bots – MIT Tech Review

There has been a huge upswell of Twitter bot activity since the start of the coronavirus pandemic, amplifying medical disinformation and the push to reopen America.

COVID-19 exposure notification settings begin to go live for iOS users with new update – Tech Crunch

Apple has released iOS 13.5, which includes support for the Exposure Notification API that it co-created with Google to support public health authorities in their contact-tracing efforts to combat COVID-19. The API requires third-party apps developed by public health authorities for use, and none have yet been released, but iOS device users already have access to COVID-19 Exposure Logging global settings.

Building a Mouse Squad Against COVID-19 – Smithsonian

The Covid-19 pandemic has skyrocketed the demand for new strains of mice to help scientists understand the progression of the disease, test existing drugs, find new therapeutic targets and develop vaccines.

Enlisting Monoclonal Antibodies in the Fight Against COVID-19 – NIH Director’s Blog

We now know that the immune system of nearly everyone who recovers from COVID-19 produces antibodies against SARS-CoV-2, the novel coronavirus that causes this easily transmitted respiratory disease [1]. The presence of such antibodies has spurred hope that people exposed to SARS-CoV-2 may be protected, at least for a time, from getting COVID-19 again. But, in this post, I want to examine another potential use of antibodies: their promise for being developed as therapeutics for people who are sick with COVID-19.

COVID-19 study looks at genetics of healthy people who develop severe illness – Washington University School of Medicine St. Loius

Washington University School of Medicine in St. Louis is one of more than 30 genome sequencing hubs worldwide participating in a study to sequence the DNA of young, healthy adults and children who develop severe COVID-19 despite having no underlying medical problems. The researchers also will study people who never become infected despite repeated exposures to coronavirus. Knowledge gained from understanding COVID-19’s extremes could lead to new therapeutic strategies for the illness.

Emory’s antibody study sheds light on COVID-19 immunity – Emory

New research from Emory University indicates that nearly all people hospitalized with COVID-19 develop virus-neutralizing antibodies within six days of testing positive. The findings will be key in helping researchers understand protective immunity against SARS-CoV-2 and in informing vaccine development. The test that Emory researchers developed also could help determine whether convalescent plasma from COVID-19 survivors can provide immunity to others, and which donors’ plasma should be used.

Antivirals

A Trial of Lopinavir–Ritonavir in Covid-19 – NEJM

After a review of the findings of Cao et al. (published in the Journal online on March 18),1 many clinicians are abandoning the use of lopinavir–ritonavir for the treatment of Covid-19. We consider this action to be premature. It is crucial to realize that although this trial did not show that the time until clinical improvement was meaningfully better than standard care among patients with severe Covid-19 who received lopinavir–ritonavir, the trial was statistically underpowered to show this outcome. In addition, the analyses of secondary outcomes (which still require confirmation) suggested that lopinavir–ritonavir may be associated with substantial lowering of overall mortality (19% in patients in the lopinavir–ritonavir group vs. 25% in the standard-care group), the risk of severe adverse events (20% vs. 32%), and the risk of respiratory failure or acute respiratory distress syndrome (13% vs. 27%).

Vaccine

SARS-CoV-2 Prototype Vaccine Protects Macaques – Genetic Engineering and Biotechnology News

The only thing better than one new study showing positive COVID-19 vaccine results in monkeys is two studies. The papers, published back-to-back in Science this week are some of the first to show that non-human primates can develop protective immunity to SARS-CoV-2—a finding critical for vaccine and public health strategies.

The global scientific community has joined forces in an unprecedented effort to understand, track, forecast, test for, and find a cure for the current coronavirus pandemic. But in a crisis where every second lost means more loss of lives, solidarity alone isn’t enough. Supercomputers are enabling a vastly accelerated pace by which scientists can conduct research and collect and analyze data. Never have they proven their value to society more than during this COVID-19 pandemic.
