"This test data is obviously abnormal. Is there something wrong with the instrument?" On the eve of the National People's Congress and the National People's Congress, the reporter went to the Institute of Infectious Diseases Medical Department of the Fifth Medical Center of the General Hospital of the People's Liberation Army to interview Chen Weiwei, the representative of the National People's Congress and the chief technician of the Institute. At that time, she was video-connecting with a technician from a hospital in Sierra Leone. After careful inquiry, Chen Weiwei analyzed the reasons and put forward countermeasures, and the test data soon returned to normal. "From 2019 to 2022, I accompanied the fourth and fifth groups of military medical experts in Sierra Leone to carry out the medical mission of foreign aid. After returning home, my colleagues from Sierra Leone often communicated with me on the Internet, and they would also ask us for help in case of difficulties. Medical treatment has no borders, and we have formed a deep friendship." Recalling the details of the assistance to Sierra Leone, Chen Weiwei was full of emotion. After the outbreak of COVID-19, Chen Weiwei, who has been committed to the detection, clinical research and prevention of infectious diseases, and other members of the military medical team for Sierra Leone aid, jointly planned to set up a series of indicators for COVID-19 severe early warning detection, prepare testing reagents, organize emergency drills, effectively improve the detection efficiency, and play a positive role in stabilizing the situation at the moment. Sierra Leone has limited medical conditions, high incidence of malaria and AIDS, and low level of laboratory diagnosis. After the hands-on training and one-to-one one-to-one teaching of a group of medical team members of the Sierra Leone Army, represented by Chen Weiwei, the medical capacity of local medical staff has been significantly improved, especially the level of clinical laboratory diagnosis. During the aid to Sierra Leone, Chen Weiwei often led the members of the military medical team to investigate the local common disease spectrum, and drove hundreds of kilometers deep into remote areas to deliver medicine to local villagers. "From the moment we put on the white robe of the 'Chinese Military Medical Group', we always remember that we are not only the doctor who saves the lives of the wounded, but also the envoy of the friendship between China and Serbia, and we must go all out to perform our duties," said Chen Weiwei. After returning to China, Chen Weiwei invested in clinical basic research of infectious diseases. As the newly elected representative of the National People's Congress, she prepared relevant suggestions on strengthening the co-construction and sharing of military and local medical and health resources and promoting the integrated training of military and local medical and technical personnel. "It is our duty to protect the health of officers and soldiers and the combat effectiveness of the troops," said Chen Weiwei. (Outlook New Era)
