Dengue fever continues to spread, and several patients have died. In addition to the hot sale of anti-mosquito products, there are also online remedies claiming that drinking guava juice can treat dengue fever. Overseas Chinese in Indonesia once said that if local people were infected with dengue fever, doctors would recommend eating red guava and drinking guava juice. However, Zhuang, deputy director of the CDC, said that these remedies have not been proved to be effective in treating dengue fever by clinical trials, and he suggested that drinking more water and taking more rest is the fundamental way to treat dengue fever. Infection with dengue fever will lead to water shortage in the body, which is the main cause of patients' illness aggravation or death. Zhuang pointed out that maintaining water balance in the body is the key to treating dengue fever. At the initial stage of dengue infection, there will be symptoms such as fever, headache, muscle or bone pain and loss of appetite. In addition, nausea, vomiting, diarrhea and so on are also common symptoms, which easily make patients in a state of water shortage due to water loss. Zhuang explained that most infected people can have a chance to recover naturally by supplementing more water and taking more rest in the early stage, but some patients, such as infected people or the elderly, and people with chronic diseases (such as diabetes), are high-risk groups that lead to the aggravation of dengue fever. Studies have shown that the patient's condition is aggravated because the permeability of microvessels increases after infection, which leads to water (plasma) leaking out of blood vessels, thus leading to shock and complications. If, after the doctor's assessment, it is found that the patient's physical condition allows him not to be hospitalized, he can instruct the masses to drink more water after returning to China and ask them to pay attention to whether there are warning signs. In case of persistent vomiting, severe abdominal pain, dyspnea, bleeding, cold limbs or change of consciousness, you must go back to the hospital immediately for further treatment.
