I’m an expert on online disinformation, misinformation, and mathematics relevant to disease transmission. Recently I’ve been answering a lot of common questions about Covid-19 on social media, trying to dispel misconceptions and falsehoods. I’ve compiled a list of the most common responses, with the hope that this makes this information more easily accessible to others. Note: I am not public health or medical professional, however, I have taken extra care to square all my responses here with official guidance and medical advice.
