2020 has a terrible start, because a sudden epidemic caught everyone's heart.
As of the early morning of February 7, 31260 cases have been diagnosed nationwide, far exceeding SARS more than ten years ago.
Seeing the rising number of infection cases, the outbreak of new pneumonia in Wuhan has become more serious.
At the same time, since the outbreak of the virus, there have been countless news, hot searches, rumors and rumors that have triggered daily discussions.
so many people can’t help but have a question in their minds:
Why did we fail to learn from our previous experience?
The answer to the question may be in this documentary recently launched by Netflix-
"Pandemic: How to Prevent an Outbreak of Influenza"
Pandemic: How to Prevent an Outbreak
There are 6 episodes in total, each of which lasts less than 50 minutes. The
production team followed up and interviewed groups fighting on the front line of influenza from all over the world, including doctors, scientists, officials, agency representatives, volunteers, etc. From the perspectives of medical staff, researchers, and vaccine developers,
presents the different situations and enlightenments of the United States, India, Vietnam, China, etc. facing Ebola, avian flu, swine flu and other epidemics.
is different from general medical documentaries that are partial to knowledge and popular science. The film also focuses on social issues and realistic thinking. The director
spent a lot of detail describing the current public policy in response to the epidemic, leading the audience to get to know the heroes who are fighting on the front line of the flu, and understand their efforts to prevent the next global epidemic.
I have to say that this documentary on Netflix is too appropriate to be released recently. As a popular science documentary on medical subjects,
did not attract much attention at the beginning.
Just a few hours after the documentary went live, the local government of Wuhan announced the "closed city". The aggravation of the epidemic made the documentary popular quickly.
especially looks at the current time node-the clues and details in the
film may be quite meaningful, and the worries and predictions are happening now.
The threat that cannot be thrown away
The history of mankind is a history of fighting various germs.
Almost every once in a while, viruses or bacteria will sweep the world and bring a catastrophe to mankind.
From the plague, cholera, and the flu at the beginning of the last century, to today’s SARS, swine flu, avian flu... Fighting viruses is the norm for mankind.
But as told in the documentary:
correct understanding of disease is the basis for overcoming it.
In the process of humans conquering nature and animals, they have never given up instinctive resistance.
With the improvement of the quality of life, the human food chain has become more and more complicated, and brand-new viruses brought by seafood, livestock, poultry, and wild animals are always threatening human society.
When a brand new virus is brought into the animal body and humans have no natural immunity to it,
our human system cannot resist the infection, the infection may become fatal.
The vast majority of viruses currently known are transmitted from wild animals to domestic animals or some intermediate host, and then to humans.
, especially in recent years, has proved that many epidemic viruses are related to bats.
For example: Ebola virus, SARS, Middle East Respiratory Syndrome, and the new coronavirus that is now raging.
It can be said that bats are the "memory" of various viruses.
The biggest feature of epidemic viruses is: high infectivity and rapid spread. After infecting the human body, the
virus can quickly spread among people through coughing, sneezing, etc., and even breathing, which is a way to spread diseases.
only needs one person and one host to cause an outbreak to cause an epidemic.
In just a few weeks, a new type of highly virulent influenza strain can make our cities powerless to resist.
As a medical worker in the documentary saidLike:
only needs one person to cause an epidemic. We are basically a human-shaped incubator.
If you miss one case of Ebola, you will infect six more and then double again.
In the hundred years after the huge epidemic at the end of World War I, humanity is also changing: the total population exceeds 7 billion, and the three-dimensional transportation network of land, sea and air extends to every corner of the earth; developed animal husbandry has crowded a large number of animals in a small space... …
for viruses-each item of
is "good news" conducive to their spread, and new viruses are emerging in endlessly. The
documentary quoted a data model made by epidemiologists, and the calculation results are quite shocking:
with the current level of population mobility, a virus can conquer a large city in two weeks, and spread across the country in a month. Infects the world in a month. Compared with the current reality,
can be said to be exactly the same as the spread of Wuhan pneumonia. The first case of
new pneumonia occurred in early and mid-December. For more than a month, it has radiated the whole country with Wuhan as its center.
In overseas countries, whether it is Thailand, South Korea, Japan, neighboring China, or Germany and France as far away as Europe, there have been confirmed cases, and the speed of transmission is amazing.
is precisely because of this, the epidemic virus is like the sword of Damocles hanging over the head of human beings-
is destined to be a protracted battle against the epidemic.
fights the "epidemic"
Since the virus is always there, how to overcome, or even defeat, becomes an important matter. In addition to being highly contagious, the
influenza virus is particularly difficult to treat, and the fatality rate is far greater than the cure rate. The average fatality rate of
Ebola is about 50%, and the fatality rate can reach up to 90%. Although the fatality rate of
SARS is low, it spreads surprisingly fast...
plus many viruses continue to mutate, the original virus The vaccine has no protective effect on the newly emerging epidemic virus subtypes.
Take the flu as an example. The seasonal flu vaccine needs to be updated every year to deal with the type of flu virus that year.
If you get a flu vaccine, the human body will be protected for a period of time, but the continuous mutation of the virus will make the vaccine ineffective, so it needs to be vaccinated again. This has led to
-
current medical technology has no preventive measures, vaccines or therapeutic interventions.
But this does not mean that the problem is really unsolvable.
In fact, scientific elites all over the world are trying to develop a universal vaccine that can fight all new viruses. Although progress is slow, this field has infinite development prospects.
In the future, if the influenza virus universal vaccine technology is successfully applied to various rapidly mutating pathogens, it will be a huge breakthrough on the road to creating a patient-free category.
On the other hand, in the face of epidemic viruses-
, in addition to treatment, is also important to prevent. The
documentary shows people's efforts in all aspects of epidemic prevention and control, and the epidemic prevention system needs to be linked together.
For example:
needs resources to develop effective vaccines;
wants to popularize vaccines, so that all classes can be vaccinated and can be treated after illness;
must have epidemic prevention and isolation measures to avoid large-scale community Disseminate and avoid infection of medical staff;
allows the community to trust medical staff in their management and seek medical treatment in time. The words of an Indian medical scientist in the
documentary are particularly impressive:
cannot resist the epidemic by itself, neither doctors nor the government. Only the three working together can defeat it.
It can be said that fighting an epidemic virus is a work that affects everyone.
From the top down, the government needs to provide adequate resources; from the bottom up, the people need to trust the science and medical system.
ultimately cuts off the path of new viruses infecting humans, requiring the joint efforts of scientists and every member of human society.
take precautions
apart from the virus itself, peoplePerhaps the biggest enemy of the epidemic is ignorance and contempt.
In Rajasthan, India, more than 5,000 people contracted "swine flu" during the 2018-2019 flu season, and the death toll exceeded 200.
At first, no one paid attention to the epidemic, thinking that:
was just a cold.
According to the local method, some honey, turmeric and lemon are enough, maybe just like we superstitiously believe in Banlangen and Shuanghuanglian. The government did not pay enough attention to the contagiousness of the "swine flu", and it was not until the epidemic spread that the health department that had inferiority realized that "this is a disease in our department".
We are on the other side of the earth. Before the outbreak of the epidemic, some people did not have much sense of crisis. In the
news, there will be people who insist on going out every day, without wearing a mask, still continue unhealthy habits, and even go out when sick, thinking that they just have a cold.
's lack of attention to epidemics stems from humans’ neglect and even indifference to others.
As long as the pain does not happen to oneself, after the epidemic has passed, the pain and struggle of the epidemic disease and the busyness and sacrifice of medical staff can be thrown out of the sky.
A few years later, another epidemic came quietly, but at this time people are still immersed in the confidence of past diseases.
Some scholars in the documentary put forward such a point:
next epidemic will only be a matter of time, we don’t know where and how it will happen, but it will happen.
It can be said that the war between humans and epidemics will never stop, and it is very likely that it will never really win. More scholars at
are outspoken:
believes that China is the focus of the next stage of epidemic prevention work.
Look now, this is almost a prediction!
So here comes the question-
What can we ordinary people do in the face of epidemic diseases?
First, we must face the epidemic, but don't be overly nervous.
In the case of the spread of the epidemic, it is normal for everyone to panic, but the ultimate victory over the epidemic is calm and rational.
Second, wash your hands frequently, go out less frequently, and wear a mask.
strictly abides by these nine words. It is to protect one's own life and is also responsible for his family.
Third, do not believe in rumors, do not eat indiscriminately, and monitor the body temperature of family members and yourself at any time.
Each of us can only protect others if we protect ourselves.
Fourth, those who have the ability can lend a helping hand. Under the
epidemic, there are no bystanders. This is what each of us should do.
Finally, the old saying goes well:
is not too late.
Although the current situation is still unclear, we are still willing to believe that we will be able to tide over the difficulties in the end.
But please remember that this war itself is a protracted war.
After overcoming the difficulties, how to avoid repeating the same mistakes is the more important issue before everyone.
