The harm of Omicron virus, some patients will have symptoms of general fatigue after being infected with Omicron virus strain, and some patients will feel general fatigue. At this time, you'd better go to the hospital to check to see if you are infected with the virus. What is the harm of Omicron virus?
Harm of Omicrovirus 1
The former COVID-19 is not over yet, but now the virus has mutated again, and Omicron has appeared. Many people don't know much about this virus. Omicron is more contagious and is a variety of COVID-19. However, the harm of this virus is inconclusive. Because there is not much data showing the harm of this virus, we can't speculate for ourselves. So it's still too early to draw conclusions. Because this virus is a new mutant strain, we need to wait for experts to get specific data to know how harmful it is. Academician Zhong Nanshan said: It will take some time to judge the harm of Omicron mutant. . However, as long as we take protective measures and protect ourselves, I believe we will not be infected by this virus. There is no need to panic excessively, as long as normal measures are taken to prevent and control the epidemic, there is almost no problem.
Omicron (English name: Omicron, serial number: B. 1. 1.529) is a variant of neocoronary pneumonia.
2021165438+1On October 26th, WHO held an emergency meeting to discuss B.1.529 COVID-19 mutant. After the meeting, WHO issued a statement, which listed it as a variant of concern and named it Omicron.
Although it was named after the Greek letter 15, it was the 13 COVID-19 strain officially named since the outbreak of Xinguan pneumonia. No one explained why it was named after two Greek letters.
According to WHO reportNo.165438+1October 26th, Omicron was first confirmed in South Africa on June 5438+065438+1October 9th. Reports No.24 and No.26 were recognized as "the most worrying variants" by WHO, which was the first time since the outbreak of COVID-19.
Harm of Omicrovirus Ⅱ
At present, it is observed that the incubation period and infection period of patients infected with Omicron and Delta are close, but it needs to be observed because of the short epidemic time of Omicron.
It is worth noting that there is no systematic research data on the infectivity, pathogenicity and immune escape ability of Omicron mutants in the world.
1 1 On the evening of 29th, Omicron mutant has important amino acid mutation sites of spike proteins of the first four VOC mutants, including enhancing cell receptor affinity and virus replication ability. According to epidemiological and laboratory monitoring data, the number of cases infected with Omicron mutant in South Africa has increased sharply, and it has partially replaced Delta mutant. The infectivity needs further monitoring.
Is COVID-19 vaccine still effective in Omicron?
In view of this, National Health Commission said that studies have shown that the mutation of K4 17N+E484A or N50 1Y indicates that the immune escape ability is enhanced; Omicron mutant has triple mutation of "k417n+e484a+n501y"; This mutant combination may reduce the protective effect of some antibody drugs on Omicron mutants, but the immune escape ability of existing vaccines needs further monitoring and research.
So far, many domestic vaccine companies are paying close attention to this variant and starting to develop new vaccines. Liu Peicheng, spokesman of Kexing Holding Biotechnology Co., Ltd., said that information and samples related to the new variant have been actively collected and obtained through the global partner network to understand the influence of Omicron strain on the existing inactivated vaccine in COVID-19 and the necessity of developing variant vaccine. If necessary, the company can quickly promote the research and development and mass production of new vaccines, and can guarantee the required vaccines.
Harm of Omicrovirus 3
Omicron is a mutant strain of COVID-19, and its symptoms are similar to those of COVID-19, mainly including weakness, headache, muscle soreness, throat discomfort and other symptoms. Some patients occasionally have a slight cough and runny nose, similar to the initial cold. When the disease worsens, it will not rule out the impact on people's respiratory system, but the symptoms of the virus are still being found. If you are infected with Omicron, if you don't take relevant preventive measures, it will spread to more people, mainly through the air. The most serious harm is life-threatening, so you should take relevant preventive measures now.
Early manifestations of Omicron
1, fatigue
Some patients will have symptoms of general fatigue after being infected with Omicron strain, and some patients will feel general fatigue. At this time, you'd better go to the hospital to check to see if you are infected with the virus.
2, muscle pain
After suffering from Omicron strain, some patients will have muscle aches, just like catching a cold. Everything is sore, but if there are no other symptoms, don't worry. When you have the flu or the common cold, you will have symptoms of whole body pain.
3. My throat itches and hurts.
After suffering from Omicron strain, patients will feel itchy throat, but this is caused by many reasons. If there are no other symptoms, don't worry. However, if you have been exposed to Omicron recently, you must attach great importance to it and go to the hospital for nucleic acid testing in time.
4, mild cough
After being infected with Omicron, a few patients will have a slight cough. Sometimes there is phlegm in my throat, but I can't cough it out, which makes me feel uncomfortable. But if it is a mild cough, it may be a common cold or pharyngitis.
5, runny nose
After suffering from Omicron strain, some patients will have symptoms of runny nose, but if there are no other symptoms, no treatment is needed. For example, patients with common cold and frostbite. It will have a runny nose, so it is not a big problem to simply have a runny nose.
Step 6 have a headache
After suffering from Omicron strain, a few patients will have headache symptoms, but they should not be one-sided, and should be judged according to the symptoms. For example, migraine sufferers occasionally have headaches.
The first case of death from the new Omicron occurred in Britain.
According to the BBC, the first death case of a new strain of Omicron occurred in Britain at 12+03 local time, which is also the first death case of Omicron in the world.
Sajid Javid, the British Health Minister, said that there were 47 13 confirmed cases of Omicron in Britain, accounting for about 20% of the total cases in COVID-19. Under the influence of Omicron, at present, the number of infected people in Britain is estimated at around 200,000 per day. Britain raised the alert level of COVID-19 to level 4 on 12.
Dzhavid said with concern: "At present, the proportion of this case in London has risen to more than 44%, and it is expected to become the main COVID-19 variant in the capital in the next 48 hours."
Dzhavid said that Omicron is spreading at an alarming rate, and the number of infected people doubles every two to three days, adding that it is too early to judge whether the symptoms of the new strain are mild.
The first unknown case caused public outrage in Britain.
The first death of Omicron in Britain aroused public anger at the lack of transparency in the government. Experts asked the government to announce the first death case of Omicron in Britain, such as the vaccination situation of individuals, whether they belong to susceptible population and whether Omicron is the main cause of death.
British Prime Minister Boris said: "At least one patient was confirmed dead in Omicron." However, Boris did not disclose the age of the deceased or whether the deceased had potential health problems.
Cairol Sicora, a medical professor and oncologist, said that the government did not provide enough death information to the public, which caused "unnecessary panic".
Who warns humans to underestimate Omicron!
According to the UN website 14, the Director-General of WHO, Tedros Adhanom Ghebreyesus, revealed that Omicron strains now exist in 77 countries and regions and are spreading at an unprecedented speed. He pointed out that it is wrong to think that this COVID-19 variant is "moderate".
Don't underestimate Omicron
Tan Desai said: "Omicron is spreading in any variety at a speed that we have never seen before. We are worried that people will think that Omicron is gentle. Of course, we now know that we underestimated the harm of this virus to us. "
"Even if Omicron does cause only minor diseases, the number of cases may once again overwhelm the unprepared health system. I need to make it very clear that vaccines alone cannot get any country out of this crisis. Countries can and must take effective measures to prevent the spread of Omicron today. " He said.
Take all epidemic prevention measures
Tedros Adhanom Ghebreyesus warned that it is wrong to "pick and choose" just to stop the epidemic. He stressed: "This is not a question of vaccine, but a question of keeping social distance. This is not a vaccine problem, but a need for ventilation or hand hygiene. Take all these measures, stick to it and do it well. "
He said that in the past 65,438+00 weeks, the number of vaccines delivered by COVID-19's vaccine purchase mechanism exceeded the sum of the first nine months of this year, and most countries put them into use immediately after obtaining vaccines.
He said: "A few countries are facing challenges in launching vaccines and rapidly expanding their scale. WHO and our partners are working closely with these countries to overcome the bottleneck. Although we expect further improvement in supply, this does not guarantee that our hard-won gains are fragile. "
Give priority to the most vulnerable groups.
Tan Desai said: "We will ensure that health workers, the elderly and other high-risk groups get the main vaccine dose, thus saving the most lives."
"In most countries, people who are hospitalized and die are those who are not vaccinated. Therefore, even in countries where vaccines are most easily available, people who are not vaccinated must be given priority. " He pointed out that in order to curb the global epidemic, the primary task of each country "must be to protect the least protected people, not the most protected people."
At present, about 4 1 countries are still unable to vaccinate their 10% population, and 98 countries have not yet reached 40%. Tedros Adhanom Ghebreyesus stressed: "If we end inequality, we will end the epidemic. If we allow inequality to continue, we will allow the epidemic to continue. "
