According to US media reports, recently, the US mainland is suffering from unprecedented "three major disasters", namely viruses, hornets and rats. If you add to that the "murderous discrimination" in the United States now, it is really "four mountains".
According to reports, in order to slow the spread of the new coronavirus, restaurants in many cities in the United States have chosen to close or only provide takeaway services, which makes it difficult for rats in the city to eat leftovers in restaurant bins. Desperate rats take to the streets in search of the only food to eat.

According to videos posted on social media, New Orleans, Chicago and New York were all captured by rats. During the day, swarms of rats poured into the streets in search of food and even climbed into car engines. A passerby even spotted nearly 30 rats in a small spot on a street corner. Sometimes for a little food, a group of rats will tear their hearts and lungs in order to eat each other's stomachs, even at the expense of eating their own cubs, like murderers.
In the matter of the murderous bumblebee coming to the United States, the American people were already very afraid of it. This time, rats everywhere evolved into "killers." The American people are really insecure. In the face of the abnormal behavior of rats, urban rodent experts also gave a corresponding explanation: rats are also a mammal. When they are hungry and feel like they are going to starve to death, they often make crazy moves and will desperately try to keep themselves alive. Rats that have lost their food source will flee to other places where they still have a source of food, competing with the rats who originally lived there for food. Whoever can fight can get enough food to survive. In this case, the attack power of the rat will be greatly increased. People are better off taking a detour than provoking them.
(This?) Bigger than many pet dogs. )
These crazy rats attracted the attention of many cities, and they also took action to catch rats. The panicked CDC even gave a report on how to prevent and control mice, which gave three methods of prevention and control. The first is to tighten the entrance blockade of homes and companies in an attempt to prevent rats from entering. The second is to clean up domestic garbage and vegetation suitable for rats in time. The third is to remove the rations of domestic pets from the yard to avoid attracting rats.
The only good news in this case is that rats can't spread COVID-19, but people can't take it lightly. After all, mice are carriers of more than 50 diseases. The "Plague of Justinian" in the 6th century AD and the "Black Death" that swept across Europe in the mid-14th century AD were both caused by rats. The plague of these three worlds. In addition to spreading the virus, rats can cause other hazards, such as invading human buildings and biting off cables. In New York City, 26 percent of cable breaks and 25 percent of unidentified fires in New York City are caused by rats.
I don't know what the president of the United States thinks about the sudden outbreak of the plague. After all, no one knows everything better than he does.
