Searches for “coronavirus AND sun” had different start times across countries but peaked at the same time for multiple countries. Conclusions: Patterns in the start, peak, and doubling time for “coronavirus AND 5G” were different from the other misinformation topics and were mostly consistent across countries assessed, which might be attributable to a lack of public understanding of 5G technology. Understanding the spread of misinformation, similarities and differences across different contexts can help in the development of appropriate interventions for limiting its impact similar to how we address infectious disease epidemics. Furthermore, the rapid proliferation of misinformation that discourages adherence to public health interventions could be predictive of future increases in disease cases. %M 33264102 %R 10.2196/24425 %U //www.mybigtv.com/2020/12/e24425/ %U https://doi.org/10.2196/24425 %U http://www.ncbi.nlm.nih.gov/pubmed/33264102
