  • The Risks – Know Them – Avoid Them

    Informative blog post summarising the dangers of enclosed spaces with a high density of people and poor air circulation in spreading COVID-19:

    Ignoring the terrible outbreaks in nursing homes, we find that the biggest outbreaks are in prisons, religious ceremonies, and workplaces, such a meat packing facilities and call centers. Any environment that is enclosed, with poor air circulation and high density of people, spells trouble. [….] Basically, as the work closures are loosened, and we start to venture out more, possibly even resuming in-office activities, you need to look at your environment and make judgments. How many people are here, how much airflow is there around me, and how long will I be in this environment. If you are in an open floorplan office, you really need critically assess the risk (volume, people, and airflow). If you are in a job that requires face-to-face talking or even worse, yelling, you need to assess the risk. If I am outside, and I walk past someone, remember it is “dose and time” needed for infection. You would have to be in their airstream for 5+ minutes for a chance of infection. While joggers may be releasing more virus due to deep breathing, remember the exposure time is also less due to their speed.

  • ‘Finally, a virus got me.’ Scientist who fought Ebola and HIV reflects on facing death from COVID-19

    Dr. Peter Piot reflects on his bout with COVID-19:

    ‘Many people think COVID-19 kills 1% of patients, and the rest get away with some flulike symptoms. But the story gets more complicated. Many people will be left with chronic kidney and heart problems. Even their neural system is disrupted. There will be hundreds of thousands of people worldwide, possibly more, who will need treatments such as renal dialysis for the rest of their lives.’
