I think it should be treated differently. For people living in poverty, the disabled, children and others, it should be free. It is more appropriate to collect the cost of pure nucleic acid materials symbolically. Objectively speaking, for citizens who earn thousands of dollars a month in most cities, the test of tens of dollars a month is still affordable. However, in some places, a routine check-up costs eight yuan, and a family of five charges forty yuan, one month 1200 yuan. Because of the epidemic, people can't go out to work and have no income. Obviously, it will increase the cost of living and make the life that is not rich worse. Anyone who has experienced in the countryside knows that many old farmers have always lived frugally and carefully. Even if it is not a penny, it should be said that they are still very careful, whether they are rich or poor.

Therefore, the charge for nucleic acid testing can be tried out in cities, even in rural areas, especially in towns and villages with low income. Moreover, COVID-19 has long been defined as a public health event, and nucleic acid testing is not only for one's own personal safety and health, but also for others, mass organizations and the whole society. Therefore, the test of skilled individuals can be charged, and so can the unified standardized test, unless it is extremely difficult in the local area.

Because testing one item is not entirely for personal needs, but more for the safety of the whole city; Second, the normalization test is too frequent. Many places are now tested twice a week, 8~9 times a month, even if they are mixed, it will cost tens of dollars a month.

Those special people, such as those engaged in catering express delivery, are tested four times a week. If they are all at their own expense, it will be a big expense in one year. Therefore, whether the practice of charging for nucleic acid testing is pushed forward, I think it is necessary to make a comprehensive evaluation and be cautious.
