Tansmition

“Even for the flu, which we’ve studied for decades, we still don’t know how much is transmitted by aerosols or by touching contaminated objects.” Civil and environmental engineer Linsey Marr, who co-authored an influential commentary urging authorities to acknowledge the potential for airborne transmission of COVID-19, emphasizes that there are many unanswered questions.

STATISTICS - SBC

A  Sociedade Brasileira de Cardiologia está de parabéns pela implantação de seu site STATISTICS e pela realização da vido conferência que tive a felicidade de assistir no dia  de hoje.

Dying soon

Would most covid-19 victims have died soon, without the virus?

 new study suggests not

“Sacrifice the weak”, urged a sign at a protest against Tennessee’s lockdown on April 20th—though whether the person holding it was trolling the other protesters is unknown. Some claim social distancing is pointless, since covid-19’s elderly victims would soon have died of other causes. In Britain many pundits have said that two-thirds of the country’s dead were already within a year of passing away. They cite an estimate made in March by Neil Ferguson, an epidemiologist at Imperial College London who advises the government.

Mr Ferguson notes that two-thirds was the upper bound of his estimate, and that the real fraction could be much lower. He says it is “very hard” to measure how ill covid-19’s victims were before catching it, and how long they might have lived otherwise. However, a study by researchers from a group of Scottish universities has attempted to do so. They found that the years of life lost (ylls) for the average Briton or Italian who passed away was probably around 11, meaning that few of covid-19’s victims would have died soon otherwise./.../

Scientists have discovered six entirely new coronaviruses lurking in bats in Myanmar. 

These viruses are in the same family as the SARS-CoV-2 virus that is currently spreading across the globe; but the researchers said the newbies aren't closely related genetically to SARS-CoV-2 or to the two other coronaviruses that cause severe infections in humans — severe acute respiratory syndrome (SARS), which caused the 2002-2003 pandemic, and Middle East respiratory syndrome (MERS)

These Historic Photos Show How San Francisco Survived the Last Pandemic

You can see parallels between the community response to the 1918 Spanish Flu and Covid-19

Covid-19 has completely changed the way we live, and it feels unprecedented. But the world, and San Francisco, has actually been here before, a little over 100 years ago during the deadliest flu epidemic in American history, referred to as the 1918 Spanish Flu. Back then, the city — like now — shut down schools, emptied streets, improvised hospitals, canceled events, encouraged mask-wearing, and most of all, firmly warned to stay at home.

Taking a look back at photos from that year, it can be jarring to see such similarities to today and interesting to see what they did differently (for better or worse.) In the image above, dozens of men lie in a warren of narrow beds separated by simple cloth screens, forming a sea of white. It’s reminiscent of photos we’re seeing today of hospitals crowded with Covid-19 patients around the world. But the men in this photo weren’t sick yet — like us, they’re practicing social distancing. Although… not up to our standards today.

The coronavirus outbreak reached a somber milestone in the U.S. on Thursday (March 26) — the nation now has more coronavirus cases than any other country in the world.

A new study rests on several big assumptions, but highlights the desperate need for antibody testing.

On March 24, a headline in the Financial Times proclaimed that "Coronavirus may have infected half of UK population," suggesting that many people in the region may have already recovered from and developed some immunity to COVID-19.

But is that actually true?

The news article focused on a new study from the University of Oxford, which has not been peer reviewed or published in a scientific journal. The study authors collected available data about deaths tied to the novel coronavirus, called SARS-CoV-2, reported in both the United Kingdom and Italy, and used these numbers to model how the virus might have spread through the U.K. so far.
