Omikejon is coming! How do we respond?

On the afternoon of February 21, a press conference held in Chengdu informed that the first indigenous case reported by Chengdu city has preliminarily completed the whole genome sequencing of the new crown virus, and the result is the Omi kerong variant, and the sequencing of other cases is also underway.

The "Omikeron" variant has the characteristics of strong transmissibility and short incubation period. The outbreak has detected a number of cases in a very short period of time, distributed in five districts and counties of Chengdu. Combined with the epidemiological investigation, the cases showed a cluster of living spaces and working spaces. Most cases have lower Ct values, indicating a higher viral load and a higher risk of transmission. Of the 9 cases currently reported, the contact relationship is very clear.

O'Mikron is coming, what should we do? Are the current protective measures still effective? Are existing COVID-19 vaccines effective? ......

Sichuan disease control experts said:

You don't have to worry,

The mainland has many successful experiences and methods in dealing with the "Omikejong" variant

The existing protective measures and prevention and control methods are still effective!

Scratch the point!

Be sure to enhance the awareness of protection,

Implement prevention and control measures

Do a good job of personal protection.

1. What are the new features of the New Coronavirus Semikron mutation strain?

Compared with the Delta mutant, the Aomi Kerong mutant is more disseminated and hidden. After infection with the Omikejong variant, the symptoms are relatively mild, mainly manifested as: fever, dry cough, sore throat, headache, fatigue, nasal congestion, etc., resulting in infected people are not easy to be found in time.

Therefore, to prevent the Aomi Kerong mutation, we should not take it lightly, pay more attention to personal protection, maintain social distancing, conscientiously fulfill personal prevention and control responsibilities, and actively cooperate with various prevention and control measures.

2. In the face of the Ami kerong mutant strain, are the current protective measures and methods still effective?

effective. The Omikejong mutation is still a new coronavirus in essence, similar to the previous transmission of the new crown virus, so conventional protection methods are still effective.

(1) Frequent hand washing, more ventilation, wearing masks, less gathering, and maintaining social distancing are still effective means of protection. Wearing a mask is also applicable to blocking the Opichron variant, even if the full vaccination and vaccination of the booster needle have been completed, it is also necessary to wear a mask in indoor public places, public transportation and other places.

(2) Moderate disinfection, do a good job of environmental cleaning. The Site of Mutation of the Omiljunn variant is the Spike Protein, and the envelope protein of the virus is still sensitive to the current disinfectant, so the disinfectants and disinfection methods currently used are still effective for the Omilcroon strain of the new crown virus.

(3) Do a good job of personal health monitoring. When there are suspected symptoms of new crown pneumonia, such as fever, cough, shortness of breath and other symptoms, timely monitor body temperature and take the initiative to seek medical treatment.

(4) Reduce non-essential entry and exit. Travel to high-risk areas should be avoided as much as possible, and personal protection during travel should be strengthened to reduce the chance of contracting the Aumechjung variant.

3. What should I do if I have symptoms of suspected new crown pneumonia?

After infection with "Omikejong", the patient's symptoms will be relatively mild, only some cases will have fever, and some cases will have imperceptible symptoms such as muscle soreness, throat discomfort, and dry cough. If you have the above symptoms, especially in the family, company or relatives and friends, many people have suspicious respiratory symptoms, you should be more vigilant, you should wear a mask immediately, avoid taking public transportation, and go to the nearest hospital fever clinic to take the initiative.

4. The effect of existing vaccines on the prevention of infection of the Aomi Kerong variant

effective. The results of the existing studies show that the Olmi kerong variant does not completely immunize to escape from the existing vaccine; the existing vaccine still has a certain protective effect on the Aomi kerong variant, but its ability to prevent infection has declined; it has not been found that the Olmi kerong variant causes an increase in the rate of severe illness and mortality, and for the Aomi kerong variant, the existing vaccine is still effective in preventing severe illness and death.

5. Effect of the Omikeron variant strain on existing nucleic acid detection reagents

The genomic analysis of the Omikerong mutant strain showed that its mutation site was not located in the primer and probe target area of the nucleic acid detection reagent published in the eighth edition of the "Novel Coronavirus Pneumonia Prevention and Control Plan" in mainland China, which did not affect the sensitivity and specificity of mainstream nucleic acid detection reagents in mainland China.

Tips

The "Omi Kerong" variant strain is highly transmitted, in order to resist the virus, please be sure to implement various prevention and control measures and do a good job in personal protection.

Maintain good habits such as wearing masks, washing hands frequently, ventilating frequently, gathering less, dividing meals, using public chopsticks, and one-meter lines, and cooperate with epidemic prevention and control measures such as scanning codes, bright codes, and nucleic acid testing.

People returning to Sichuan from outside the province (especially those who have returned to Sichuan from cities and cities with positive infections in the past 14 days) and counties (districts) where the local epidemic has occurred in our province should do nucleic acid testing as soon as possible within 24 hours.

Actively pay attention to the relevant information on the epidemic released by the government, especially the activity trajectory of the local cases, and check whether there is any intersection. If you have a recent history of living in an epidemic area, intersecting with the trajectory of positive cases, receiving a reminder text message, or a health code changing to a "red code" or "yellow code", please immediately report to your village (community), unit or hotel, cooperate with various epidemic prevention and control measures and complete nucleic acid testing as soon as possible.
