PITTSBURGH — A little more than three weeks ago, officials in Pittsburgh announced a milestone enviable for almost any major city in America: A day had gone by without a single new confirmed case of the coronavirus. It was good news for a city that had seen only a modest outbreak all along, even as the virus raged through places like Philadelphia and New York.

Coronavirus has been detected on particles of air pollution by scientists investigating whether this could enable it to be carried over longer distances and increase the number of people infected.

The work is preliminary and it is not yet known if the virus remains viable on pollution particles and in sufficient quantity to cause disease.

The US is rolling out digital contact tracing. How has it been working in other countries?

vox.com - by Shirin Ghaffary - April 18, 2020

If and when lockdown restrictions are lifted in the US, would you agree to let the government anonymously track your interactions with people within a 6-foot radius to control the spread of Covid-19?

That’s an increasingly urgent question as President Trump and state governors debate how and when to safely reopen the US economy — and as technology is being touted as a solution that would help people reenter public life.

And tech giants are stepping up. Last week, Apple and Google announced a plan to turn phones into opt-in Covid-19 tracking machines that would, if all goes as planned, make it easier for health officials to identify and alert people if they’ve been exposed to the virus.

Late Monday, the Pentagon announced a $415 million contract to commission 60 decontamination systems that will allow millions of highly protective N95 face masks to be reused.

The system, which can process up to 80,000 masks per day, has been called a potential "game changer" for the front-line health care workers and first responders who rely on the masks, according to hospital officials concerned about a shortage of protective equipment to shield their staff from COVID-19.

But the story of how this system came to be is a testament to what can happen when a doctor and an engineer — who happen to be husband and wife — ask, "What if?"

Researchers in Finland have released a shocking simulation that apparently shows how respiratory droplets from just one cough in a grocery store can linger in the air for “several minutes” and travel across two aisles, possibly infecting other shoppers nearby with coronavirus.

Aalto University, the Finnish Meteorological Institute, VTT Technical Research Centre of Finland and the University of Helsinki studied how aerosolized particles released from the respiratory tract when coughing, sneezing or even talking flow through the air.

Preliminary results indicate that tiny particles carrying the coronavirus can linger in the air for longer than originally thought, reinforcing the importance of completely avoiding crowded spaces, or at the very least following social distancing guidelines.

As the world grapples with the escalating coronavirus pandemic, China reopened the city of Wuhan on Wednesday, allowing its 11 million residents to leave for the first time in over two months, a milestone in its effort to combat the outbreak.

But while the operation to contain Wuhan’s coronavirus outbreak has been hailed as a success by China and many international health experts, it didn’t come easy.

Using virus case data, official reports and over a dozen interviews with officials, residents and scientists in Wuhan, Reuters has compiled a comprehensive account of how the military-style quarantine of the city unfolded.

Researchers in Shanghai hope to determine whether some recovered coronavirus patients have a higher risk of reinfection after finding surprisingly low levels of Covid-19 antibodies in a number of people discharged from hospital.

A team from Fudan University analysed blood samples from 175 patients discharged from the Shanghai Public Health Clinical Centre and found that nearly a third had unexpectedly low levels of antibodies.

In just ten minutes, Gauthier used extra tubing to multiply the number of patients that could be ventilated.

themindunleashed.com - by Elias Marat - March 23, 2020

As health care facilities across the globe continue to grapple with a general shortage of supplies to help them with the devastating coronavirus pandemic, one doctor in Canada has managed to use a bit of creativity, ingenuity, and an idea inspired by YouTube to help future patients.

Dr. Alain Gaithier, an anesthetist at the Perth and Smiths Falls District Hospital in Ontario, was worried about the possibility that his rural hospital’s one ventilator would hardly be able to carry the load that the CoViD-19 outbreak could entail.

So Gauthier, who has a Ph. D. in respiratory mechanics, borrowed an idea conceived by American doctors Greg Neyman and Charlene Babcock in 2006 to double the capacity of a single ventilator.
