Before we knew it, the new coronavirus has existed in life for nearly three years. The emergence of the new coronavirus has broken the originally peaceful life and hindered the development of the economy.

Unconsciously, New Coronavirus has existed in life for nearly three years. The emergence of the new coronavirus has broken the originally peaceful life and hindered the development of the economy.

Faced with the growing number of confirmed cases, people couldn't help panic. When will the new crown that has lasted for nearly three years disappear?

Why is the new crown so difficult to completely eliminate?

and mutations faster

Any virus will mutate during evolution, mostly towards adapting to the environment, especially RNA viruses like COVID-19, which mutation is normal and faster.

is named Greek letter α(α), β(β), γ(γ) and δ(δ) viruses respectively; different variants have different characteristics, but they have one common feature, the variants are more toxic.

. The incubation period is long.

For SARS virus , its incubation period is 2-7 days. Most people will experience high-risk conditions on the third day, and they can detect and treat them early. In addition, the SARS virus has weak contagious ability during the latent period, so , SARS, is easier to eliminate.

The incubation period of the new coronavirus is between 1-14 days, so the quarantine time is two weeks. During this period, it also has strong contagious ability, and various asymptomatic patients make it particularly difficult to control the epidemic.

. Strong infectivity

On Epidemiological , the basic infection number (R0) is an important indicator for measuring the virus's infectious ability. The larger the R0 value, the stronger the virus's contagiousness. Currently, the new generation of delta mutant strain R0 has such strong transmission ability, as fast as chickenpox and smallpox.

The most important thing is that there are many ways to contagious the new coronavirus, including food, frozen products, and respiratory transmission, making it more difficult to absolutely prevent the new coronavirus.

When will the new crown epidemic end? Huang Jianping’s team made a prediction, and Academician Zhong Nanshan also expressed his views

For the general public, the most concerned issue is when the new coronavirus will end? . The team of Huang Jianping, an academician of the Chinese Academy of Sciences, made a prediction: the new crown will end at the end of November 2023.

The prediction made by Academician Huang Jianping’s team did not come out of thin air, but based on the results of inferred by multiple experiments. They used the new crown self-test system to repeatedly infer the current epidemic situation, with an accuracy rate of up to 94%.

research team also pointed out that the main reason for the fewer confirmed cases in mainland China is the implementation of strict restrictions. Therefore, before developing a more effective vaccine, we should still abide by epidemic prevention requirements, wear medical masks, and restrict large gatherings to slow the spread of the new crown epidemic.

Academician Zhong Nanshan also expressed his views on the end of the new crown epidemic. He said: The epidemic may exist for a long time, but large-scale transmission can be controlled. We will gradually open up in the process of dynamic removal, which shows that the epidemic can still be prevented and controlled.

What symptoms will the human body appear after being infected with the new coronavirus?

, fever

Usually, colds and fever will not cause repeated fever after the body returns to normal body temperature. However, the recurrence of fever caused by the novel coronavirus infection is difficult to control. In addition, a few people have mild symptoms and no fever. After patients with

, dry cough

, they will experience symptoms of lung infection , among which dry cough is the most common. Some early patients will have slightly mild symptoms after taking antibiotics and other drugs on their own, but their condition will worsen in a short period of time.

, eye symptoms

virus may also survive and reproduce in the eyes, thereby causing viral conjunctivitis , which is generally manifested as symptoms such as eye pain, itchy eyes, foreign body sensation, tears, increased eye secretions, and ht will appear ml1 conjunctiva congestion , conjunctiva edema,

, skin symptoms

is infected with the novel coronavirus and may also cause irritation to the skin, resulting in symptoms such as erythema, papules , and papules and vascular lesions may also occur. After the patient is infected with the novel coronavirus, the respiratory and digestive systems are attacked by the virus and their function is reduced. At this time, the patient will feel weak all over. Without further medical intervention, it may lead to various complications, such as hypoxemia , acute respiratory distress, sepsis, metabolic acidosis and other serious diseases.

How do we take self-protection measures in the current epidemic situation?

. Pay attention to personal hygiene

You must maintain frequent hand washing and good respiratory hygiene habits, use soap and hand sanitizer to wash your hands with running water, and maintain good respiratory habits. Use tissues, towels, and arms to cover your mouth and nose when coughing or sneezing, and avoid facing others.

. Wear a mask

The main transmission method of the novel coronavirus is droplet transmission and close contact transmission. In order to prevent the new coronavirus pneumonia, you must wear a mask when going out, enter indoors in public places, do not take off your mask, and avoid places with dense crowds.

. Strengthen physical fitness and improve immunity

Zhang Wenhong made a clear statement regarding the new crown epidemic:

There is no magic medicine in the world that can quickly remove the virus. For patients with mild symptoms, it does not require a particularly complicated treatment and can finally recover. This proves that human immunity is very important. Most viral diseases are eliminated through immunity.

Therefore, in addition to taking personal protection during the epidemic, we must also improve our personal immunity.

(1) Supplementing vitamin C

Vitamin C can effectively improve the body's immunity. Eat more fresh fruits and vegetables in normal times. When you encounter flu outbreak or have low immunity, you can take some vitamin C tablets.

(2) Protein intake

such as meat and milk. It is recommended that meat be mainly white meat such as chicken, fish, etc., and eat less red meat such as pork and mutton. The fat in red meat, cholesterol is higher than that in white meat, and should not be consumed in excess.

(3) Don’t stay up late

Staying up late is a killer to reduce immunity. Staying up late can promote the secretion of corticosteroids. This hormone can keep the body excited and cope with the need to stay up late, but it will greatly reduce the body’s immunity.

(4) Moderate exercise

Excessive physical exercise can make the body tired and immunity decrease. Reasonable exercise every day can promote metabolism, maintain active vitality and immunity.

(5) Smoking quit smoking and limiting alcohol

Long-term smoking causes lung damage, reduces the body's oxygen supply, excessive alcohol intake increases the burden on the kidneys, and weakens the body's resistance.

(6) Optimistic mentality

Cultivate a wide range of interests, keep a happy mood every day, and a positive optimistic mood has a certain auxiliary effect on improving immunity. Anxiety, excessive psychological pressure, sadness, depression, etc. can reduce the body's immunity.

In addition, under the guidance of a doctor, vaccination with seasonal influenza vaccines and immune enhancement drugs is also a way to improve the body's immunity.
