Do you know when you can eat after the epidemic? The sudden epidemic disrupted people's life rhythm and wanted to have dinner with relatives and friends, but the epidemic is still not over. When can we have dinner together after the epidemic? I have carefully arranged it, hoping to help you.
When can I eat after the epidemic 1 1? When can I eat after the epidemic?
Generally speaking, you can't have dinner until 28 days after the epidemic ends.
2. When can it be called after the epidemic in 2020?
Although many places have achieved zero growth at present, this does not mean that the epidemic has passed. Because after the increase of 0, there may still be imported cases, suspected cases, latent patients, asymptomatic infected people and so on.
Therefore, the usual practice of epidemic prevention and control is to observe two incubation periods, that is, 28 days in COVID-19. Even if there is only one new case in these 28 days, the calculation needs to be restarted, because the new patient may come into contact with a group of people. In addition, the 28 days mentioned here refers to the whole country, depending on a province or a city, there is no new reference within 28 days, which is of little significance.
Therefore, we must work hard to maintain it after the epidemic.
At present, some areas have gradually liberalized the restrictions on group dinners.
With the control of the epidemic, some areas have gradually liberalized the restrictions on group dinners.
● On March 2 1 day, Wenling, Zhejiang Province issued a notice that large-scale banquets such as wedding banquets can be held.
● On March 22nd, gusu district, Suzhou plans to launch "Five Systems for Accelerating Resumption of Work". Birthday banquets, full moon banquets and other banquets with strong demand from residents are allowed under the condition that the place is ventilated and the health of personnel can be traced back. At present, the system is widely soliciting opinions from all walks of life. Judging from the current voting results, nearly 60% agree!
● On March 25th, emergency headquarters, Sichuan issued an announcement: it decided to terminate the clause of "temporarily prohibiting collective dinners (including self-organized collective banquets in rural areas)" in Announcement No.2.
Aggregation activities gradually show a recovery trend from prohibition to conditional opening. I believe that with the further stabilization of the epidemic, the whole country will return to normal.
Regarding when we can have dinner together after the epidemic, it is still necessary to make it clear that the epidemic is not over and there are risks. We must take strict precautions and not relax!
When can I eat after the epidemic? 2 How to choose masks under different standards?
1. national standard (China standard): civil mask standard GBT 326 10-20 16 and labor protection mask standard GB2626-2006.
1 and GBT 326 10-20 16 mainly classify masks according to two indicators: filtration efficiency and protective effect. From low to high, it is divided into four grades: D, C, B and A. The higher the grade, the better the effect.
2. According to the "leakage rate" and "filtration efficiency" of masks, GB2626-2006 classified masks into 90(KN90, KP90), 95(KN95, KP95) and 100(KN 100, KP/kloc-0. This standard is close to international standards, such as EU standard EN 149, NIOSH certified masks in the United States, AS 17 16 in Australia and JS-T-8 15 1 in Japan.
As can be seen from the above table, KN and KP have their own emphases. KN is for non-oily particles (such as neocoronavirus) and KP is for oily particles (used in special working environment). To prevent and control the epidemic situation, KN95 should be the most cost-effective under the national standard.
II. EU labor protection mask standard EN 149. There are three grades: FFP 1, FFP2 and FFP3, and the effect of FFP2 is similar to the national standard N95.
3m mask
Note: The well-known "3m mask" is a global brand, and every country implements corresponding standards.
Third, NIOSH certification in the United States. Similar to the national standard (the national standard is KN and the American standard is N), the standards of N95 and KN95 are close: N stands for non-oily environment (P stands for oily), and 95 stands for filtration efficiency.
South Korea, Japan, Australia and other standards are not introduced. Let's start with Korean standard KF94. Compared with KN95, it has its own advantages. KF94 has certain effect on oily environment, but KN95 has better filtration effect in non-oily environment. Therefore, KN95 is more suitable for epidemic prevention and control than KF94.
For ordinary people, it is enough to know the relevant standards. Whether it is to prevent and control the epidemic or use labor services, there is nothing wrong with buying masks according to standards. You don't have to know the raw materials and processes, such as the core raw material "meltblown cloth", just to meet the needs of use. As long as you know, masks on the market will be marked with relevant standards. For example, the N95 mask must be "meltblown cloth", so don't worry.
