I don't think there would have been any consequences because the conditions in ancient times were different from now, and we can't look at what might have happened in ancient times in the same way as we do now.
When the New Crown Epidemic broke out, the New Crown Epidemic did have a major impact on our lives. Some people feel that if the New Crown Epidemic had happened in ancient times, it would likely have had more serious consequences, but this is actually an oversimplification, which I will answer in detail in the following points.
The New Crown Epidemic would not have had more serious consequences in ancient times.
This reasoning is very simple because there are many viruses that we have experienced since ancient times, and the New Crown Pneumonia can only be described as a virus that can be ranked in the top 10 in the current history. Many of you have heard of the Anthony Plague and the Black Death, including the smallpox virus that we often refer to, and these epidemics have been a bit more destructive to mankind. In a way, we've experienced much more serious viruses in ancient times.
Ancient societies were not as densely populated.
The reason why the New Crown epidemic was able to spread so quickly in a short period of time was also due to the fact that the New Crown virus is exceptionally strong in its ability to spread, and on the other hand, it also had a lot to do with population density. Because the population density of the current society is particularly high, so the new crown has already had a hotbed of spread, but if we put it into the ancient society, in fact, the population density of the ancient society is not so great, so the new crown epidemic may not be able to spread down.
Ancient populations didn't live that long either.
We can understand this way, the New Crown Epidemic is more harmful to the elderly, because it is difficult for the elderly to recover after being infected with the New Crown Epidemic, but for the young people, the New Crown Epidemic is less lethal to the young people. Because the ancient population didn't live that long, there were very few people who lived longer than 50 years old. For ancient societies, if an outbreak of the New Crown Epidemic did occur, it would actually not be that devastating to the entire society, because the number of elderly people in ancient times determined the number of people affected by the New Crown.
