Disease

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.

STUDY: measurement of facemask efficacy for filtering expelled droplets during speech

Tue, 2020-08-11 23:12 — mike kraft

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.
