I think H 1N 1 Influenza, like common influenza viruses, "challenges" our immunity through air transmission. As long as our immunity is strong, we will not be infected by it, so whether a person will get H 1N 1 is related to a person's immunity. Whether drinking oolong tea can effectively prevent H 1N 1 depends on whether it can improve people's immunity. I think the strength of individual immunity is determined by our physical fitness, so in order to enhance our ability to resist H 1N 1, what we should do is to strengthen exercise and improve our physical fitness. In addition, H 1N 1 is a highly contagious virus, and prevention is the priority. Pay more attention to the occasions where you go in and out, your personal lifestyle and habits, and keep yourself away from the source of the virus. Through the above two efforts, I believe that everyone will be able to defeat this virus. I hope my personal opinion is useful to everyone.
