New crown virus "strongest variety" hit?"O'K戎" is infectious to high?

2021-11-29 18:05:29 33 ℃

Recently, a new crown virus variant (B.1.1.529) spreads spread in African countries such as Botswana and South Africa, making the world again.

It is reported that the B.1.1.529 new crown variant of this test, the World Health Organization is qualitatively "close attention to variants" (VOC), named OMicron.

1. Infect O'K戎 virus symptoms

According to reports, O'K戎 currently only triggered "mild disease", symptoms include muscle pain, fatigue, and with minor cough. No infected people lost their taste and smell, symptoms were not obvious.

2. New variants infectivity or increased by 500%? What is the difference between Delta virus?

Delta strains have a total of 15 mining protein mutations. At present, O'Kek's poisonous strains have been known to 32 minimous proteins, more than double more than Delta poison.

Some experts believe that these variations are diversified, which may cause viruses infectious and evaporated to evade vaccine immunity. An American epidemiological expert even believes that "new variants may have 500% of powerful infectious power."

But it is necessary to be clear

Most variations, does not mean that the virus is contagious, the key is whether the variation site will affect the infection capacity of the virus, and the number of variation sites and the propagation capacity is not determined. relation.

Even if Okith has strong immune escape, it does not mean that the virus can be combined with the host cell, so it takes at least 2 weeks in the future to clarify whether the Austrian virus communication capacity is stronger.

3. What is the emergence of Ao Tielike?

O'Kek's spread is very fast, and the variant virus strains found in Botswana in southern Africa have been spread in many countries in Europe. In order to prevent O'Kek into the mirror, there have been many countries have adopted immigration restrictions.

Previously, four variants were incorporated by WHO, namely Alpha (B.1.1.7), Beta (B.1.351), Gamma (P.1) and the most propagated Delta ( B.1.617.2), Okeki (B.1.1.529) is the fifth.

The emergence of O'K戎 means that the new crown virus varies very quickly, and more new varieties may occur later.

At present, although its spread is faster, the symptoms are not serious. However, after all, O'K戎 has a short period of time, and cannot figure out its popularity from existing data.

So how much harm is there, will not make the disease more serious, and whether it needs to perform vaccine development, it is necessary to judge according to subsequent research.

Therefore, O'K戎 can develop into a future poison, and it takes further observation. It can be determined that this virus carries a lot of mutations, and there will be more challenges for epidemic prevention.

4. How big is the O'K戎 threat?

Due to the current research data of O'K戎 viruses, no one has a complete understanding, so it is not clear how much the threat is made.

However, you can rest assured that China's current rapid response and dynamic cleaning strategy can cope with various types of new crown virus variants, which will not have too much impact on China. Existing new crown vaccines also need to continue inoculation.

5. O'Koi lethal life rate

Although the number of cases infected O'K戎 virus is increasing, because of the short time, it is still unclear whether other variant strains such as Delta are more serious than that of Delta.

So now whether it is pre-propelled whether the O'Kek poison species causes critical illness, and the mortality rate is still too early.

But regardless of how the virus varies, the protective measures we need to take are constant. It is wearing mask, not gathering, maintaining social distance, paying attention to personal and environmental sanitation, living room and working environment, and actively vaccination.
