Intermittent chills are one of the symptoms of malaria, an infectious disease caused by Plasmodium, characterized by intermittent chills, high fever, sweating and splenomegaly, and anemia. The main purpose of cutting off the transmission route is to eliminate Anopheles mosquitoes and prevent their bites. Remove Anopheles larvae breeding sites and the use of insecticidal drugs. Personal protection can apply repellents or mosquito nets to avoid being bitten by mosquitoes. Control the source of infection, improve the reporting of epidemics, and treat patients with malaria and those with malaria parasites. Malaria can be divided into three types of malaria: inter-day malaria, three-day malaria and falciparum malaria according to the attack cycle. The main symptom of malaria is chills and shivering, which is called chills in medical science. The chills last for a few minutes and then the fever starts to rise, which can be as high as 40°C. After about 3 to 4 hours, the body sweats heavily and the body temperature gradually decreases to normal. In addition to chills and fever, the patient often feels weak, tired, anorexic, dizzy, and sore and sleepy in the back and limbs. In the case of children, they may sometimes have seizures. In severe malaria, coma and delirium can be seen, and even life-threatening. Every year, 200-300 million people in the world still get malaria, and as many as 3 million patients die from malaria. Prevention of intermittent chills caused by malaria: 1. Sleep well Pay attention to rest, as it is easy to develop when the body’s resistance is low due to exertion. 2.Eat well Eat more onion, ginger, garlic, chili leek, garlic pasta and other products that help Yang to replenish Yang energy. Eat less mangoes and wet products, eat more pineapple, white radish, yogurt and other damp and appetizing products. Diet is especially important in the rainy season. 3.To take anti-malarial drugs According to statistics, the incidence rate of preventive medicine is 30%, and 50% for those who do not take it. When you first arrive at the infected area, you should take it for 3 months, because when you first arrive, you will be tired from the journey, you will not be able to adapt to the water and soil, and your resistance will be low, so it will be difficult to adapt to the disease. 4. Pay attention to warmth. Add and subtract clothes at any time, pay attention to appropriate activities, but should not sweat a lot, because cold and a lot of sweat are easy to hurt Yang Qi. Do not drink cold, sleep in the open air at night, mosquito nets should be hung, pay attention to indoor ventilation and dryness, especially in the rainy season. 5.Take medicine in the rainy season There are many mosquitoes in the rainy season. From the perspective of Chinese medicine, the rainy season is heavy with dampness, which is easy to trap the spleen and injure the yang, and malaria in the rainy season is difficult to heal and easy to repeat.
