Coronavirus data bias | Busting virus myths

Editor's note

One of the most asked questions when it comes to the coronavirus pandemic is which country has the best strategy for curbing the spread of COVID-19. Many of us are anxiously following the daily updates of ever rising death rates across the world, hoping to learn the answer. But different countries have radically different approaches to testing, sampling and reporting. This leads to significant biases in the data, which can make country comparisons useless. If a country has a low death or infection rate compared to others, it is not necessarily because it is managing the virus any better or that the virus has infected fewer people. Luckily, as Norman Fenton, Magda Osman, Martin Neil and Scott McLachlan explain, there are ways to improve the modelling, something which should ideally be done in parallel with random testing.

Nicolas Guilhot, meanwhile, examines why so many conspiracy theories have sprung up in the months since the virus first emerged. And Stanley Shanapinda busts the dangerous myth that radiation from 5G technology can spread the coronavirus.

No, 5G radiation doesn’t cause or spread the coronavirus. Saying it does is destructive

Stanley Shanapinda, La Trobe University

As if attacks on health workers weren't upsetting enough, reports indicate broadband engineers are now also being abused - as conspiracy theorists link 5G technology with to COVID-19's spread.

Infecciones y estigmas: lecciones de la pandemia del VIH para el mañana de la COVID-19

Sergio Villanueva Baselga, Universitat de Barcelona

Si miramos al pasado (y también a parte del presente), veremos cómo los enfermos de la epidemia del VIH (que ya ha matado a más de 30 millones de personas) fueron y son estigmatizados. En España ya empezamos a ver justicieros de balcón y vecinos que denuncian a otros. Es momento de mirar hacia atrás para no cometer los mismo errores.
