The end of tourism? Christopher de Bellaigue publishes an insightful Guardian long read about the devastated global tourism industry. One key paragraph: “Tourism is an unusual industry in that the assets it monetizes – a view, a reef, a cathedral – do not belong to it. The world’s dominant cruise companies (…) pay little towards the upkeep of the public goods they live off. By incorporating themselves in overseas tax havens with benign environmental and labor laws – respectively Panama, Liberia and Bermuda – cruising’s big three, which account for three-quarters of the industry, get to enjoy low taxes and avoid much irksome regulation, while polluting the air and sea, eroding coastlines and pouring tens of millions of people into picturesque ports of call that often cannot cope with them.”

Those who might be tempted to attend a political rally should read the summary of COVID Reference’s Transmission chapter:
- It appears that a high percentage (as high as 80%?) of secondary transmissions could be caused by a small fraction of infectious individuals (as low as 10%?; Endo 2020); if this is the case, then the more people are grouped together, the higher the probability that a superspreader is part of the group.
- It also appears that aerosol transmission might play an important role in SARS-CoV-2 transmission (Prather 2020); if this is the case, then building a wall around this same group of people and putting a ceiling above them further enhances the probability of SARS-CoV-2 infection.
- It finally appears that shouting and speaking loudly emits thousands of oral fluid droplets per second which could linger in the air for minutes (Anfinrud 2020, Stadnytskyi 2020, Chao 2020, Asadi 2019); if this is the case, then creating noise (machines, music) around people grouped in a closed environment would create the perfect setting for a superspreader event.
Stay away from mass gatherings.
