Obesity and infection are interacting with each other. Infection causes obesity, and obesity contributes to the occurrence and deterioration of infection. The sources of infection that cause obesity include viruses such as adenovirus, intestinal viruses, bacteria such as intestinal microbes, parasites, and the antibiotics that cause these microbes to change. The above risk factors cause chronic inflammatory reactions in the body, and in ad- dition, obesity is further accelerated when bad eating habits are accompanied. Among the infections that occur often in obese people and worsen their condition are various viral infections such as influenza viruses and coro- navirus, bacterial infections that cause urinary tract infections or periodontal infections, respiratory infections such as bronchitis, pneumonia, floor infections and infections in surgical areas. Infection in obesity increases complications, and reduces the effectiveness of antibiotics and vaccines. The mechanism between obesity and infection is a decrease in immunity resulting from increased chronic inflammation. Based on the evidence that obesity and infection cause and effect each other and interact with each other, it can be used for prevention and treatment of obesity. Studies related to the development of obesity vaccines and the maintenance of healthy in- testinal microbes are under way, which is expected to reduce obesity and prevent future prevention. As a result, reducing obesity will reduce the risk and deterioration of infection.
