It's impossible that a specific medicine can cure all diseases. The largest population in the world is not any animal, but bacteria. Although the emergence of antibiotics has been able to defend against most bacteria, the height of the road is one foot, the height of the magic is one foot, and bacteria are constantly evolving.
There are many situations that will threaten people's lives and form deadly viruses, and human beings can never exhaust all the diseases.
Although medicine is developing day by day, there are still many intractable diseases that cannot be solved. For example, today's cancer is a big problem. After so many years, there is still no effective solution. In fact, cancer is not caused by bacteria, but by human genetic mutation.
Let's talk about the epidemic situation we are experiencing. We all know that pneumonia in Covid-19 has brought great losses to people, but what role has science and technology played here? We still use the most primitive isolation method to fight it. As for those scientific and medical methods, do they work for it? Obviously, it has no obvious effect, and ultimately it depends on human immunity to fight the virus.
It can be seen that the development of human science and technology is always targeted. You should first put forward a topic and then study it. You can't get the answer directly without the research object.
So when those new situations don't happen, there can't be a specific medicine to treat them, so what humans can study is only those diseases with cases. As for what kind of unprecedented diseases there will be in the future, it is unpredictable.
In short, it is a disease that has not happened before a project, and it is impossible for human beings to understand it, so there is no way to produce specific drugs in advance.
There are some irresistible external factors, such as the virus carried by animals is transmitted to people, and people are defenseless, so how can human beings overcome the diseases generated at this time?
That bat has become a man with a back-pot, but there is nothing humans can do about it.
