? Why are the vast majority infected with the elderly?
? First of all, the location of this spread is the key node of this epidemic spread. Lin arrived at Harbin West Station by K350 train from Nancha, Heilongjiang, and taught in Aishang Health Center in Fan Jiatun Town, Gongzhuling City and Quality Life Workshop in Tonghua City successively, causing group infection.
Infected people are exposed to high-concentration aerosol environment for a long time in a closed space, and most of them are middle-aged and elderly people, with basic diseases, poor immune function and easy to be infected. ? Zhao Qinglong said. Many epidemic prevention and control personnel suggested that theaters, KTV, restaurants, hotels and other places where people gather are easy to supervise, but training places such as medical care, insurance and wealth management. Often in the dark, gables are hidden, and some are hidden in residential buildings, which is difficult to supervise. Among them, there are a large number of health centers, and a large number of elderly people often get together to listen to lectures, buy health care products and receive gifts. Since the epidemic stabilized some time ago, this kind of activity has been cleaned up and strictly controlled? Make a comeback? .
? ? Then, with the growth of age, the performance of various organs of the human body gradually declines, the most prominent performance is the decline of immunity, easy to get sick, and the recovery time is longer. For the elderly, decreased immunity will cause many diseases, and at the same time, it is more likely to be infected with viruses.
I hope Jilin can survive the special period, and also remind everyone to do personal protection in an emergency, don't get together, don't gather!
