Why is the virus so aggressive in the epidemic swine flu that appeared in Mexico? Swine flu is something that can be transmitted from pigs to humans, and the current phenomenon is human-to-human transmission, from human to human. Some people ask if it will be less severe than the transmission from pigs to humans, it is not. This human-to-human swine flu is a hybrid type, which means that it has 3 genes: swine flu, avian flu and human flu mixed, and in areas where swine flu appears, the direction of this flu is likely to become apparent, rapidly human-to-human, threatening young adults easily in the first place. There are already reports of swine flu taking down young adults, with 68 deaths from the flu in Mexico, 20 of them from swine flu, involving more than 4,000 people in contact. The young adults who were infected were between the ages of 25 and 45. Why is it that the more fit and immunocompetent people are, the more likely they are to be killed by swine flu? The younger and stronger the person is, the more sensitive the body’s immune function is and the higher the immune energy it exerts. Once swine flu invades such a person, his body’s immune cells will be released rapidly, and because the immune function is strong, too much is released at once, and these over-released immune cells produce a suicidal effect, destroying the balance of the body’s own immune cells, and over-immunization occurs. When the immune balance is disrupted, it causes more damage to the body. Once young adults are infected by a virus, especially a serious one like swine flu, the release of autoimmune function brings more repercussions to the body. What should be done to prevent the epidemic? Pay close attention to information related to swine flu infection, do not go to any country or region where there is a swine flu outbreak; do not come into contact with people suspected of swine flu virus infection. For example, the current international sports program, the emergence of the epidemic countries and regions, there are participating countries to propose withdrawal. The next thing is to try to avoid staying in densely populated, poorly ventilated places, and the environment in which you live needs good air circulation. Pay attention to personal hygiene and wash your hands regularly. If you have symptoms of influenza, especially if they are aggressive, you must seek medical attention immediately. Having a strong body is something to be proud of, as it is the capital to overcome illness. A good immune system can be overly sensitive to viruses, but it is still a strong body that can enable a person to escape the clutches of the disease as soon as possible in case of illness!
