La nueva normalidad: vigilancia, confinamiento y pasaportes de inmunidad

La vida que conocíamos se ha terminado, solo podemos aspirar a llegar a una nueva normalidad lo antes posible. Repasamos cómo será, qué retos tenemos por delante para lograrla y quiénes serán los más afectados en un futuro en el que solo serán libres quienes puedan demostrar que son inmunes

Reutilizar fármacos para luchar contra esta pandemia y las siguientes

Dado que la primera vacuna contra el SARS-CoV-2 llegará como pronto, hasta dentro de un año, los medicamentos tardan 10 años de media en llegar al mercado, varias empresas están analizando la eficacia de cientos de fármacos ya disponibles, algo que podría agilizar la respuesta ante coronavirus de otros tipos

Por qué es tan difícil calcular cómo y cuándo desescalar el confinamiento

Los intentos de definir las mejores formas de relajar las restricciones solo son capaces de llegar a una conclusión: los datos, modelos y predicciones se basan en grandes incógnitas e incertidumbres. Para solucionarlo, los investigadores insisten en la urgencia de monitorizar correctamente los contagios

Facebook launches COVID-19 data maps for the US, will take its symptom tracking efforts global

Many, many symptoms trackers have launched during the coronavirus pandemic, but few with the potential to reach even a bucketful of Facebook’s vast ocean of users.

Facebook launched a symptom tracking partnership with Carnegie Mellon University’s Delphi epidemiological research center early this month, and now the company now plans to expand the project outside of the U.S. In early April, Facebook began prompting some users in the U.S. with a CMU survey asking them to self-report COVID-19 symptoms. The effort is designed to help governments and health officials to predict where the virus could hit next.

Facebook will work with researchers from the University of Maryland on the expansion as the team at CMU’s Delphi develops an API that would allow any researcher to tap into the dataset.

Facebook is also collecting survey data onto its own symptom map, which visualizes the percentage of the population with COVID-19 symptoms by county and hospital referral region. The map also displays flu activity distinct from reported COVID-19 symptoms. With testing capacity still limited in many places, this kind of survey effort seeks to provide a more anticipatory picture of the virus and where it might be spreading next.

“The real-time estimates we’ve derived correlate with the best available data on COVID-19 activity, which gives us confidence that we may soon be able to give health care officials forecasts of disease activity that is likely to occur in their localities several weeks into the future,” Ryan Tibshirani, co-lead on Carnegie Mellon University’s Delphi COVID-19 Response Team, said in a statement.

The opt-in CMU survey asks Facebook users if they were experiencing coughing, fever, shortness or breath or loss of smell—symptoms that can show up in COVID-19 patients in more mild forms and that likely would be present prior to an individual seeking treatment and thus being tracked by healthcare systems.

CMU published its initial findings on Monday, which show the data collected on Facebook correlates with existing COVID-19 public health data. The research team is introducing a tool called COVIDcast, which collects aggregated data about COVID-19 activity, sorted by geographic area. Google has also joined CMU’s research effort and later this week the COVIDcast will integrate data from both Facebook and Google survey responses. So far, the project has collected nearly one million responses each week on Facebook and 600,000 through Google’s Opinion Rewards and AdMob apps.

In an op-ed in the Washington Post, Mark Zuckerberg touted his company’s efforts.

“Getting accurate county-by-county data from across the United States is challenging, and obtaining such focused data from across the whole world is even harder” Zuckerberg wrote, adding that Facebook is “uniquely” suited to aid research efforts that require surveying large subsets of the population.

After a long season of criticism, social media companies are striving for relevance in the fight against the virus. Facebook, particularly dogged by negative press and privacy scandals in recent years, was early to add UI elements promoting COVID-19 information from health experts on its platform. Still, Facebook and other social networks remain plagued by coronavirus misinformation, scammers and conspiracies, which spread quickly and have proven difficult for companies to stamp out.

Last week, a handful of U.S. anti-government protests organized on Facebook and promoted by President Trump defied the advice of state governments and public health officials, calling users to gather in public—an act of defiance that could potentially spread the virus to new communities in spite of the best efforts by state governments to protect their residents.

Microsoft built a ‘Plasma Bot’ to tell you if you can donate plasma to help fight COVID-19

Plasma taken from the blood of recovered COVID-19 patients stands a real chance of being one of the more effective short-term measures feasible in the ongoing effort to control the global coronavirus pandemic. The FDA has issued a broad call for donations from eligible individuals, and now Microsoft has built an online screening tool on behalf of the CoVIg-19 Plasma Alliance (which is funded in part by the Bill and Melinda Gates Foundation).

The “CoVIg-19 Plasma Bot” that Microsoft created for the foundation is just the latest COVID-19-related bot built by Microsoft using its technology, and its symptom self-checker for the CDC was one of the earliest large-scale efforts of its kind in the U.S. The Plasma Bot takes you through a series of simple questions to determine your eligibility, from the perspective of both your ability to meet the actual biological and health requirements, to your willingness and a ability to participate in the plasma collection process itself at a donation center.

Use of convalescent plasma, or the liquid part of blood taken from people who have had, and subsequently fully recovered from, COVID-19, is a key treatment avenue being explored by a number of different scientists and researchers. The investigations into its use take two main paths: First, direct use of the plasma injected into coronavirus patients and high-risk individuals in order to boost their own immune system for either prevention or faster recovery; and development of what are known as hyperimmune therapies, which concentrate the antibodies from donated plasma to develop treatments that are potentially easier and more effective to administer at scale.

The biggest bottleneck to overcome for the trials and therapeutics in development related to convalescent plasma is definitely the plasma itself, which can only come from patients who’ve had COVID-19 and are now fully recovered and healthy, and who also meet other standard, existing requirements for donating blood and plasma.

Unlike a lot of other treatments under investigation and development to address COVID-19, convalescent plasma has been shown to have been effective in treating other respiratory infections, and it has a long history of use for such applications.
