The new crown BA.5 mutant plants are popular, how should it be prevented?Attachment: One picture understands

At present, BA.4 and BA.5, the new crown virus Omikon, has become the world's main popular strains. Since August, there have been more than 100 local infections in 11 provinces across the country. Hainan, Xinjiang and other places have detected Omikon mutant BA.5 and their evolutionary branches. So what are the characteristics of the new crown mutant Omikon mutant BA.5?

01 What is the infectiousness?

Omikon mutant plant BA.5 has stronger transmission capacity and faster transmission than previous mutant strains, and has stronger infectious and immune escape.

What methods do you pass through?

The BA.5 propagation method of Omikon is still transmitting through the respiratory tract droplets and close contact. In a relatively closed environment, it is transmitted by gas solidarity. It may also cause infection after exposing items contaminated by the virus.

How long is the 03 incubation period?

According to the "New Coronatte Pneumonic Pneumonia Prevention Plan" (ninth edition), the average incubation period of Omikon variants is shortened, mostly 2-4 days.

What are the symptoms after infection?

Most of the infected people infected with the infection of Omir Rongju is asymptomatic infected. There are many obvious clinical symptoms and chest imaging characteristics. As a result, the epidemic is more hidden and it is not easy to find early.

After the BA.5 infected with Omikon variants, several common symptoms may occur, especially for continuous cough, nasal congestion and sore throat; another prominent symptom is extreme fatigue. The common taste and losing sense of smell after infection with the new coronal virus have become no longer common.

05 Is the pathogenicity increase?

Dong Xiaoping, chief expert of the China Centers for Disease Control and Prevention, introduced that compared with the previous mutant strains, the pathogenicity of Omikon mutant BA.5 has not significantly enhanced and weakened. The recent prevention and control practices of the Omikon mutant BA.5 epidemic in China also reminded that existing prevention and control measures are still effective.

06 Is the vaccine still effective?

On August 10th, the State Council ’s joint control mechanism mentioned that the current vaccine we use can be seen that the first one is significant in preventing severe illnesses and death effects, and the second is clear. Completing the full vaccination and strengthening needles can effectively prevent severe illnesses and death.

Do a good job of epidemic prevention and control

Everyone is the first person in charge of health. Everyone is responsible for the normalization of the new crown epidemic. Everyone should keep in mind wearing a mask, to wash their hands, ventilation, less gathering, "one meter line", and personal protection measures with public chopsticks. Essence

In addition, it is advocated that everyone will actively implement public prevention and control measures such as regular nucleic acid testing and active scanning sites in accordance with the specific epidemic prevention and control requirements in the area. Let's learn health knowledge, do a good job of health monitoring, enhance social responsibility, prevent and control scientifically, and not relax.
