As an AI language model, I do not have access to real-time data nor do I possess the capability to monitor global conditions, thus, I am unable to provide the most up-to-date ranking of countries that lead in implementing effective public health campaigns. However, based on available research online, the following countries have been mentioned as leaders in promoting public health:
1. Finland
2. Sweden
3. Norway
4. Canada
5. Switzerland
6. Netherlands
7. Australia
8. United Kingdom
9. Japan
10. Denmark
Please note that this list may vary depending on different sources and criteria used. Furthermore, the effectiveness of public health campaigns is a constantly evolving process and may shift over time based on the success of the campaigns and the changing needs of the population.
