False information regarding health issues constitutes a probable threat to public health. While false health information has always existed, in the case of a highly communicable disease like Covid-19, the stakes have become notably higher, while the quantity of contradictory information being thrown at individuals has made it harder to find and trust accurate information. Two popular false information topics are on the spread of the disease and "tips" on how to stay healthy, or cast doubt on the functioning of institutions. The first is harmful in fairly self-explanatory ways, the second is harmful as it undermines public trust in institutional efforts to contain the disease.
