Amazon has pulled more than 1 million items from its digital shelves due to claims that the products could either cure or help prevent the spread of coronavirus.

The move comes during the same week that Facebook said it would ban advertisements on its platform for products purporting to cure or curtail the spread of the virus that has so far infected more than 80,000 people, and results in almost 3,000 deaths, mostly in China.
