What enlightenment has this wave of COVID-19 outbreaks in megacities since spring brought us? See what the experts say

The spring of 2022 is not easy! After the Spring Festival and now after the May Day holiday, affected by the epidemic caused by the mutant strain of Omicron, many areas have stopped. Even during the holidays, most people did not go out to play, but chose to stay at home, especially in places like Shanghai, Beijing and other megacities with a population of over 20 million.

Through the efforts of the government and the public, the fluctuation of the COVID-19 epidemic in China has gradually shown a downward trend, but we have also learned some inspiration from the COVID-19 epidemic in several large cities since this spring.

What are the implications of this wave of COVID-19 outbreaks in megacities since spring?

1) The Omicron mutant virus strain spreads quickly and has strong concealment

The emergence of the mutant strain of Omicron has caught many cities by surprise, although we have accumulated some experience in dealing with the original strain of the COVID-19 pneumonia virus, as well as mutant strains such as Alpha and Delta. However, the Omicron mutant strain spreads stronger than the previous virus strain, and most of the asymptomatic infections make the virus more difficult to detect and more occult. So we can't treat it with the previous style of play. Only by being faster and stronger than it can we surpass the virus and defeat the epidemic.

According to the CDC, like previous variants, Omicron spreads through inhalation, direct person-to-person contact, and contact with objects containing the virus; anyone infected with the Omicron variant can The virus spreads to other people regardless of whether they have been vaccinated or have no symptoms of the disease. Although it does not cause as severe symptoms as the Delta variant, the Amicron variant has similar or even greater dangers than its predecessors.

2) Go all out to achieve "Four Responses and Four Efforts"

For the invasion of the mutant strain of Omicron, we must go all out to achieve "four responses and four eliminations", all inspections should be carried out, all should be isolated, all should be harvested, and all should be cured. This is also the case of Wuhan in 2020 It is an experience formed by China's phased victory in the fight against the epidemic since the outbreak. At the same time, in the process of fighting against the epidemic, if these four points are not achieved, it is often in a passive situation where the epidemic spreads. This reminds us that as long as we do "four responses and four efforts", we can quickly and effectively cut off the chain of epidemic transmission , Effectively protect the health of the people, including the effective implementation of medical treatment.

3) Vaccines are very important, especially for special populations such as the elderly and patients with underlying diseases

Although many of Omicron are mild or asymptomatic infections, the risk of severe illness or even death is much higher for special groups such as the elderly and patients with underlying diseases. Vaccination is an important means of preventing viral infection and endangering severe disease or even death. We need to strengthen the vaccination of these special groups in order to effectively protect the health of the people.

The Covid-19 vaccine remains particularly important as the best way to prevent people from getting Covid-19 so far. Timely vaccine coverage not only helps protect human health from Covid-19, but also reduces the likelihood of new variants emerging. Vaccination is a method of stimulating the body to produce antibodies by introducing antigens, strengthening the immune system, and reducing serious illness and mortality in patients, thereby generating active immunity. Especially for high-risk groups such as children, the elderly, people with underlying diseases, and people with low immunity.

For the omecroron variant, scientists are still studying the effectiveness of the vaccine in preventing infection with this variant. The current Covid-19 vaccine is still assessed to protect vaccinated people from serious illness requiring hospitalization and even death from infection with omegatron.

Therefore, everyone should inject booster needles in time.

Summarize

Judging from our experience in fighting the virus for more than two years, the earlier the epidemic is detected, the easier it is to be controlled. The COVID-19 pneumonia epidemic is not only a matter for the government and the community, but also a matter for the whole society. Therefore, only each of us should take good protection, get vaccinated, seek medical treatment in time when symptoms appear, and cooperate with the government's arrangements. I believe we can win this battle A fight against the epidemic.
