"Since most of the transmission is sexual transmission, you have a regional or local response to the virus"

This quote by Luc Montagnier recommends that the spread of the virus is largely due to sexual transmission, and for that reason the response to the virus need to be localized. This implies that the reaction to the infection ought to be customized to the specific area or locality in which it is present. This is because the infection may spread differently in different areas, and the action should be customized to the specific needs of the location. For instance, if the virus is spreading out quickly in a certain location, then the reaction ought to be more aggressive in that location, such as increasing testing and contact tracing. On the other hand, if the infection is not spreading out quickly in a particular location, then the reaction must be more relaxed, such as providing education and resources to help people secure themselves. By customizing the reaction to the infection to the particular area or area, it can help to minimize the spread of the infection and protect the people in that area.
