Viruses are the easiest to spread during warm winter or spring and autumn, in fact, viruses have a characteristic, that is, they are not afraid of cold but afraid of heat. So low temperatures are the time when viruses like it the most and are most active.
Now the new coronavirus.
The reason for the outbreak is that the virus spreads easily in winter, and in such a climate, the survival rate of the virus will be higher and it will not be easy to kill, which is why so many people are infected. The virus is generally at zero degrees Celsius.
At four degrees Celsius, it can be stored in the air for several weeks, which is the temperature of the southern winter.
And in the winter in the north, when the temperature is dozens of degrees below zero, the virus can still be stocked, and it will not be killed. Just wait until the temperature rises a little and the virus can be active again. But as long as the temperature rises, the virus is often easier to kill in summer, so it is difficult for infectious diseases to break out in summer, and basically infectious diseases can be basically eliminated when summer comes, SARS.
That's how it was.
Under normal circumstances, the virus is around 56 degrees Celsius and can be inactive as long as it is maintained for 30 minutes, and the virus can be killed at such a temperature. But in addition to temperature, there is also a condition that is time, so high temperature plus enough time can kill the virus. And after the summer heats up, because of the presence of the sun, there are ultraviolet rays in the sun.
Therefore, under long-term ultraviolet exposure, the genetic material of the virus can also be destroyed, so the DNA of the virus will lose its infectivity if it is destroyed.
So if you want to kill the virus, you want the temperature to rise. After all, if you keep the temperature low, the virus in the air outside may be stored for a long time, so once someone goes out and gets rid of the virus, it is easy to get sick. This is also one of the reasons why the number of people infected with the new coronavirus is very high now, and the virus that may have been left over from a few months ago can still be transmitted today.
-
For viruses, temperatures that are too high or too low are not conducive to their survival. In general, a dry environment is conducive to the survival and spread of the virus. However, in rainy weather, the body's resistance will decrease, and it is more likely to be infected with the virus.
-
The virus spreads easily in the spring and winter because these two seasons are cold. There is a comparatively damp. Then it is easy to lead to the spread of the virus, resulting in excessive microbial growth.
-
The virus spreads most easily in hazy weather and rainy weather because there is less UV exposure.
-
Viruses are most easily spread when the weather is cold, because many viruses break out in winter, and this time the virus is also active, in the cold air, the virus is very active.
-
The virus spreads most easily during the rainy season because of the humid weather, poor air circulation, and the lack of sterilization by the sun.
-
Viruses can only survive on their own, and cannot survive on their own, but bacteria are different and most can survive independently. Neither viruses nor bacteria can survive in the air, but they can. For example, the flu virus can be transmitted through the air, so wear a mask and avoid going to crowded places during the flu season.
Tiny organisms that can spread between other organisms and infect organisms (in fact, viruses cannot be metabolized by themselves, so viruses cannot be said to be living organisms to some extent). Slippery Pure sometimes uses the term "virus" to describe those organisms that circulate and infect eukaryotes; The term "phage" or "phagosome" is used to describe those organisms that spread between prokaryotes.
-
Different viruses have different transmission routes, and airborne viruses naturally exist, such as influenza virus, SARS virus, cold virus, avian influenza virus, etc., and some viruses can also be transmitted through droplets in close proximity to dense populations.
-
The virus needs a host cell to survive, and if it is about 1 minute to survive without the host cell, then if you are exposed to a sufficient concentration of virus in this area, there is a chance of infection. If it's really airborne, wait for Resident Evil, even nuclear ** can't save you without a vaccine. Therefore, as long as you wash your hands, you will not be in crowded places, and you will not be exposed to unhealthy people.
-
Viruses and the weather are actually related to each other, because some viruses are suitable for hot weather, but some viruses will break out when the weather is cold.
-
Yes, SARS also broke out in the winter and ended in the summer, so it can also be optimistically estimated that the new coronavirus will end in the summer.
-
If it is a sunny day, when the sun is very strong, the virus inventory rate will be greatly reduced, because the sunlight contains ultraviolet rays to kill the virus, and if it is a cloudy day, it will greatly increase the activity rate of the virus.
-
There must be a relationship, some viruses like heat and cold, and some are the opposite. So many viruses disappear after a period of time, not successfully**, but the environment defeats the virus.
-
Yes, but only necessary, because viruses are the most likely to multiply in warm climates, and now that global warming has exacerbated the increase in temperatures, the weather has also contributed to the growth of viruses.

Dangers of network viruses and how they spread.
Internet viruses are also harmful to users of applicable computers. I accidentally opened a letter from a stranger, and the system crashed, which has happened to many friends.
Here's how computer viruses spread on the web:
Generally speaking, the basic structure of a computer network includes a network server and a network node station. Computer viruses generally first enter the network through the workstations that have signed to floppy disks and hard disks, and then begin to spread online.
Specifically, it spreads in the following ways:
Viruses are copied directly from the server to the server.
The virus first infects the workstation, resides in the memory of the workstation, and then infects the server when running the program in the network disk.
The virus infects the workstation first, resides in the memory of the workstation, and directly infects the server through the image path when the virus is running.
If a remote workstation is infected by a virus, the virus can also enter the web server via communication data exchange.
Once the virus enters the file server, it quickly spreads to every computer in the entire network. For diskless workstations, because they are not really diskless, when they run a poisonous program on the network disk, the virus in memory will be transmitted to the program or transmitted to other files on the server through the image path, so the diskless workstation is also a breeding ground for viruses.
It can be seen from the above ways of virus propagation on the network that in the network environment, in addition to the commonality of computer viruses such as transmissibility, executability, and destructiveness, viruses also have some new characteristics:
The infection is fast:
In a stand-alone environment, viruses can only be carried from one computer to another via floppy disks, while in a network, they can spread rapidly through network communication mechanisms. According to the measurement, for the normal use of a typical PC network, as long as there is a virus on one workstation, it can infect all hundreds of computers on the network within tens of minutes.
Difficult to remove completely:
Computer viruses on a single machine can sometimes be used to delete toxic files. Measures such as low-level formatting of hard disks can completely remove viruses, and as long as one workstation in the network can be disinfected, the entire network can be re-infected by viruses, and even a station that has just completed the removal work may be infected by another workstation with poison on the network. Therefore, virus removal on workstations alone cannot solve the harm of viruses to the network.

Blacks are not stupid You know when you come to the United States that 50%+ of American civil servants are black. So what Africa lacks is education and infrastructure.
