The wife of the Brazilian president tested positive for the new coronavirus. How do foreign countries prevent the disease?

I remember that in March and April, commercial vehicles parked on the streets in the Philippines had the slogan "Stay at home or lie in a coffin" written on them. There is also the hard-core operation in Russia of releasing 500 tigers on the streets to force people to quarantine at home. The other thing is to strictly check the entry and exit personnel. After all, the infection rate of entry is also very high. It is said that North Korea has completely sealed its borders, and if anyone is found smuggling across the border, they will be quarantined on the spot. Those who seriously violate quarantine regulations in North Korea can immediately enforce the law on the spot. It is still very tough. Thanks to these tough measures, the epidemic can be controlled to a large extent. After all, the way the epidemic spreads is through person-to-person contact, so it will be easier to deal with it after cutting off contact.

However, although there are differences in how countries release tigers and coffins, they are still consistent in many aspects. For example, wear a mask, wash hands frequently, don’t gather in groups, etc. Especially in places with a high degree of development, due to the relatively high degree of automation in public places, this has also reduced the infection rate to a certain extent.

In addition, it is to ensure that people can cooperate with isolation. Countries in the West were dismissive of COVID-19 at first, but the biggest problem is that everyone from leaders to ordinary people have been negligent about the epidemic. What's more, the new coronavirus is very easy to infect. If the number of infected people is too large at the beginning, it will become more and more difficult to control later. Once the medical system is paralyzed, it will be difficult to control the number of infected people.

In addition, Iceland adopts a nationwide spot check method. After all, Iceland’s total population is not large.

Needless to say, the United States coincides with a time of frequent conflicts, and it is very difficult to isolate everyone at home. And the people themselves are indifferent to the new coronavirus, do not pay attention to protection work, and even try to contract the virus themselves. If they do not cooperate with the epidemic prevention actions, it is not surprising that the number of infected people is high. There are too many people, and the number of medical supplies, wards and medical staff are far from being able to meet the excessive demand, not to mention the psychological pressure is also very high. Therefore, it is difficult to effectively control the infected population.
