Leaving aside all the usual difficulties with collecting data of that kind, it’s worth noting that such a procedure only has a hope of producing reliable results if: * The majority if cases of Monkeypox are both symptomatic and reported. * The majority of transmissions occur by contact between people who know each other personally (rather than e.g. brushing up against each other in a tube carriage). * It is possible to share names and other details in a way that respects people’s privacy. (On the face of it, sending out surveys saying 'Sam Jones had Monkeypox, did you kiss them last week?' is just unlawful.) We may eventually get reliable information about the main vectors for the current outbreak. At present, we haven’t. No-one is hiding anything. We just don’t know because it’s difficult to find out. edit: Also note the following from the article: >For many of the confirmed cases, health officials don't know how the person caught the virus. Those infected haven't traveled or come into contact with another infected person. That means the virus is spreading in some communities and cities, cryptically.
