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 reporting of epidemics, and eradicate malaria patients and those with Plasmodium. The following diseases are the causes of intermittent chills: 1. Pulmonary malaria disease Pulmonary malaria disease refers to the damage to the lungs caused by Plasmodium vivax. The organism may or may not have typical systemic symptoms of malaria after being infected by Plasmodium and at the same time appear obvious respiratory symptoms, such as cough, coughing, shortness of breath, wheezing or chest pain. The clinical manifestations include malarial asthma, bronchitis, pneumonia, pulmonary edema and acute respiratory distress syndrome (ARDS). There is no exact statistical information on the incidence. Malaria nephropathy Malaria is an insect-borne disease caused by the bite of Anopheles mosquitoes and infection with Plasmodium. It is characterized by periodic chills, fever, headache, sweating, anemia, and splenomegaly. The incidence of the disease is high in children and is mostly prevalent in the summer and autumn. Due to the establishment of local malaria prevention and treatment institutions, the highly endemic areas in China have been basically controlled and the incidence rate has been significantly reduced.
