Does China have a malaria vaccine, why is there no malaria in China?

According to relevant data, malaria vaccine research has been going on for a century, but most of them only contain a single molecule of the pathogen, which cannot provide sufficient immunity. It is understood that the World Health Organization is promoting malaria vaccine, and the malaria vaccine is being piloted for the first time in three African countries. The vaccine protects mainly children under 5 years of age.

However, its protection rate is low, only about 30%, and the outlook is not very optimistic. But for malaria-endemic areas in Africa, it still makes a lot of sense. For travel enthusiasts, the way to prevent malaria is to prevent mosquito bites, and preventive medications, such as piperaquine phosphate, can be prepared.

Malaria is an insect-borne infectious disease caused by infection with Plasmodium parasites, especially in Africa, which is a frequent area, and will occur periodically after the disease, generally manifested as chills, fever and sweating throughout the body. In endemic or high-malaria areas, it is best to take precautions against mosquito bites, which can be prevented with drugs or vaccines.

Malaria prevention can be achieved by: 1. Management of the source of infection, ** malaria patients with current symptoms and malaria parasites. 2. Cut off the transmission route, eliminate Anopheles mosquitoes, prevent Anopheles mosquitoes, clear the places where Anopheles mosquitoes breed strongly, and widely use insecticides, and apply repellents or mosquito nets for personal protection to avoid mosquito bites.

3. Protect susceptible populations. Malaria vaccination, combined with pharmacological interventions, is expected to significantly reduce malaria morbidity and mortality.

China's anti-malaria drug artemisinin, which has saved millions of lives around the world, has been codified in WHO technical documents and replicated in other countries.

In 1967, the state launched the "523 Project"; Artemisinin was discovered in the 70s and is still the core compound of the most effective antimalarial drugs; The spread of drug-impregnated bed nets as the main measure of malaria control in many parts of the country has led to a significant reduction in the incidence rate.

Since 2010, the "137" strategy has been gradually established: that is, cases are reported within one day of discovery; Complete the survey within 3 days; Take measures such as mosquito control within 7 days to ensure that the epidemic does not spread.

After four consecutive years without local cases, on June 30 this year, the World Health Organization concluded that China had established a timely and effective malaria surveillance system capable of controlling the re-transmission of malaria, and issued a malaria-free certificate.

Hearing the news, Dong Xueshu and his colleagues, who are already in their old age, shed tears, "I studied malaria prevention and treatment at the age of 23, and now that malaria has been eliminated, I am 86 years old." Over the years, Dong Xueshu has sorted out the information and spent more than 5 years drawing the "Yunnan Mosquito Chronicle", which contains the basic knowledge of mosquitoes, which is of great significance for future disease control.

As of June 30, 2021, there are 40 malaria-free countries and regions within the scope of the whole acre. Malaria-free countries refer to countries that have been certified malaria-free by the World Health Organization, and on 30 June 2021, WHO declared China malaria-free.

Malaria is an insect-borne disease caused by infection with the Plasmodium parasite through the bite of Anopheles mosquitoes or the transfusion of blood from a person with the malaria parasite.

China is the first country in the WHO Western Pacific region to be certified as malaria-free in more than 30 years.

China was one of the first countries in the world to try to use insecticide-treated nets to prevent malaria, earlier than the WHO recommended the use of bed nets for malaria control.
