The Chinese and Lao armies will organize the "peace train-2022" humanitarian medical rescue joint exercise and medical service activities in Vientiane, punhong and surrounding areas in Laos in mid to late July. The purpose of this activity is to share the experience of the medical services of the Chinese and Lao armies, exercise and improve the coordinated action and emergency response ability of the medical services of the two armies, and contribute to the construction of a human health community. The Chinese side dispatched 149 troops and a health train, carrying nucleic acid detection shelter, negative pressure ambulance, health and epidemic prevention vehicle and other equipment. The drill will adopt the method of "connecting the health train with the secondary hospital, combining medical treatment with epidemic prevention and control", and organize rescue drills such as joint command, on-site search and rescue, joint infectious disease prevention and control, transfer and acceptance of batch wounded, and superior placement of the wounded. Medical service activities include organizing and carrying out seminars, academic lectures, and publicity and education on the prevention and control of the COVID-19. (outlook new era)
