Study hints, can’t prove, survivor plasma fights COVID-19

Mayo Clinic researchers reported a strong hint that blood plasma from COVID-19 survivors helps other patients recover, but it’s not proof and some experts worry if, amid clamor for the treatment, they’ll ever get a clear answer.

Face masks with valves or vents do not prevent spread of the coronavirus, CDC says "Masks with one-way valves or vents allow air to be exhaled through a hole in the material, which can result in expelled respiratory droplets that can reach others," the CDC says.

Coronavirus in Europe: Infections surge in France, Germany and Spain

Thu, 2020-08-13 22:57 — mike kraft

Germany has recorded its biggest daily increase in coronavirus cases in more than three months as European countries struggle to curb a surge in infections.

More than 1,200 cases were reported in Germany in the past 24 hours. Officials said the rise was due, in part, to people returning from holidays.

It came as Germany warned against non-essential trips to parts of Spain.

Meanwhile, France had 2,524 new cases in 24 hours, the highest daily rise since its lockdown was lifted in May.

The Many Symptoms of Covid-19

Thu, 2020-08-13 01:54 — mike kraft

For a Texas nurse, the first sign that something was wrong happened while brushing her teeth — she couldn’t taste her toothpaste. For a Georgia attorney, it was hitting a wall of fatigue on a normally easy run. When a Wisconsin professor fell ill in June, he thought a bad meal had upset his stomach.

But eventually, all of these people discovered that their manifold symptoms were all signs of Covid-19. Some of the common symptoms — a dry cough, a headache — can start so mildly they are at first mistaken for allergies or a cold. In other cases, the symptoms are so unusual — strange leg pain, a rash or dizziness — that patients and even their doctors don’t think Covid-19 could be the culprit.

‘A Smoking Gun’: Infectious Coronavirus Retrieved From Hospital Air

Wed, 2020-08-12 20:18 — mike kraft

Skeptics of the notion that the coronavirus spreads through the air — including many expert advisers to the World Health Organization — have held out for one missing piece of evidence: proof that floating respiratory droplets called aerosols contain live virus, and not just fragments of genetic material.

Now a team of virologists and aerosol scientists has produced exactly that: confirmation of infectious virus in the air.

Low-cost measurement of facemask efficacy for filtering expelled droplets during speech Mandates for mask use in public during the recent COVID-19 pandemic, worsened by global shortage of commercial supplies, have led to widespread use of homemade masks and mask alternatives. It is assumed that wearing such masks reduces the likelihood for an infected person to spread the disease, but many of these mask designs have not been tested in practice. We have demonstrated a simple optical measurement method to evaluate the efficacy of masks to reduce the transmission of respiratory droplets during regular speech.
