One study found that more than one in four of the most popular YouTube videos about the novel coronavirus contained misinformation. Another found that vaccine skeptics were winning the battle for Facebook engagement.
More than 70% of adults turn to the internet to learn about health and healthcare, a team of researchers in Canada said. They analyzed popular YouTube videos on a single day earlier this year, filtering for those that mentioned coronavirus.
Excluding videos that weren't in English, that ran for more than an hour, or didn't have audio or visual content, they wound up with 69 videos twith a total of 257,804,146 views. They rated each based on factual content covering symptoms, prevention, treatments epidemiology and viral spread.
