Core tip: Presumably everyone wants the epidemic to end as soon as possible, so when can we control the epidemic?

Since the outbreak in late 2019, the COVID-19 pandemic has infected nearly 500 million people worldwide and caused more than 6.2 million deaths.

Globally, Omicron led to a significant increase in new COVID-19 cases around January 2022.

Past studies have shown that even if some previous coronaviruses have successfully entered the human system, partial immunity can prevent people from getting seriously ill, which can't help but make people sigh: when will the new crown virus end!

What is the main spread of the new crown virus?

Droplet transmission

Droplet transmission in the respiratory tract is the main route of transmission, which means that in the process of face-to-face communication with patients infected with the new coronavirus, if the infected person coughs and sneezes, a large number of droplets containing the new coronavirus will be sprayed. Normal people can colonize the respiratory tract after inhaling these droplets, causing infection.

Contact transmission

Contact transmission means that droplets containing the virus settle to the surface of the object, when touched by healthy people with their hands, the virus can be contaminated to the hands, in the absence of hand washing or hand hygiene, with contaminated hands to contact the mouth, eyes, nose, can pass through the mucous membranes to cause human infection.

Aerosol propagation

Refers to droplets containing viruses mixed in the air to form a very tiny aerosol, which, when inhaled, can lead to coronavirus infection.

The new crown virus can also be isolated from feces and urine, so we should pay attention to the contact transmission and aerosol transmission caused by environmental pollution.

When will the COVID-19 epidemic end? Huang Jianping, an academician of the Chinese Academy of Sciences, made a prediction

A team of academicians Huang Jianping of Lanzhou University published a review article entitled "Whether the Omicron Pandemic Will End" in the English journal "Innovation" published by the Youth Innovation Promotion Association of the Chinese Academy of Sciences in cooperation with the Cell Press.

The forecast concludes that the COVID-19 pandemic will end around November 2023.

According to its official website, since June 2020, the system has successfully predicted more than 30 times, and its accuracy rate is as high as 94%. However, this conclusion is based on the current development of the pandemic, and if a more contagious virus appears in the future, the result will be different!

Although the new coronavirus is "fierce", it also has 3 "weaknesses"

Weakness 1: Intolerance to high concentrations of alcohol

In the process of fighting the new coronavirus, experts found that the new coronavirus is not intolerant to alcohol, and in a certain concentration of alcohol, it will soon be killed and lose infectivity. However, the concentration of alcohol should reach more than 75%, that is, to reach the medical level.

In addition to alcohol, chlorine-containing disinfectants can also kill the novel coronavirus.

Weakness two: the time to survive in the air is relatively short

The study found that after the new coronavirus leaves the host, it can only survive in the air for about 2 hours. Many people may think: 2 hours is still short? We can't look at absolute values, we have to look at relative values.

Compared with other infectious viruses, the air survival time of the new coronavirus is relatively short, like A flow, which survives in the air for up to 24 hours.

Weakness three: not resistant to disinfectants

Alcohol has a certain fat solubility, which can kill the virus with envelope structure, dehydrate and degenerate the protein, resulting in virus inactivation. It is recommended to use 75% alcohol for the best disinfection effect. In addition, chlorine-containing disinfectants and peroxide disinfectants can also be effectively disinfected and are mostly used in daily necessities.

Is COVID-19 the biggest plague in history?

The new crown pneumonia is not the biggest plague in history, there have been many plagues that are bigger than it, such as the previous Black Death, most of the plagues that have occurred so many times in history are plagues, only the plague of smallpox has been ended by humans, and other plagues have been slowly eliminated by isolation.

Today, we are still making a final effort to prevent the new crown epidemic.

But the new crown is the most widespread, the most influential, the most deadly plague in the past hundred years, and the new crown epidemic we are experiencing now, according to the number of deaths, is also several million, but the impact on all mankind is far inferior to other plagues.

Of course, this also benefits from our current advanced medical means, I believe that in the near future, we will be able to defeat the new crown.
